A

Recording okay.

B

So this is first.

C

A

Meeting so welcome to to the team, and the idea here is.

C

It's uh it's really about.

A

Let me see if I can uh oh yeah.

C

A

I could see myself anyway, um it's about yeah.

B

I'm excited the thing that excites me about this kind of relationship is that we can build a network of.

A

People like us in the different countries we're collaborating all together. The combined energy combines to.

D

Whatever any powerful corporation can do.

A

You know and it's something that hasn't.

B

Really happened.

A

B

History, I don't know of any organization, that's a.

A

Formidable uh enterprise.

B

That simply distributed open collaborative in that way, like the only thing we have for all the successful companies, it's like you.

D

A

D

Investor funding: you keep everything proprietary.

C

You go forward, you're not open to others, but that's really missing.

A

The point of the distributed.

C

Economy that we're.

A

C

B

And simply create a different paradigm of a.

A

Inclusive economy of abundance.

B

A

I like that and.

B

I look forward to that because.

A

I think we can set a new precedent for how more people.

B

A

Be doing work that they like.

B

I was just reading some statistics today that worldwide.

A

It seems like 85 percent of.

C

The population.

A

C

Not like their work.

A

You know I was.

C

Looking for the united states, it's similar in the united states, it seems to be like 65 or so.

A

uh Depending where.

C

You look so it's like.

A

Let's make an infrastructure where we are more fulfilled right, and I think uh part of this is the distributed nature of things you.

B

Have you simply have more control over what you're doing you don't have to subscribe to some big boss or uh some big? You know.

A

Some large-scale structures, which a lot of times uh start breaking.

E

Down once they reach a certain size, because I mean that's the whole case for distribution schumacher perhaps was a seminal figure in the uk who wrote a book called small is beautiful. He worked in the coal industry and he he found that he wrote a book called small is beautiful. The essential thesis was that look be.

A

If organizations.

B

In the human world.

A

B

A certain scale like they'll, they just start.

A

Breaking down and we.

B

Haven't figured that one out yet.

A

And I think this is a chance to do it, so I'm excited.

B

uh Right now, so we have you working in india, so there's a.

A

Guy named ken in indonesia.

B

Who's working on a printer, the guy john.

A

B

Blackley in.

A

New york state there's a guy in south.

B

Africa, who.

A

B

On the printer there he's kind of on standstill, as he's got.

A

His work that he's addressing right now, but let's keep building that and and part of that, like the thing to notice about.

E

A

E

How do we collaborate in this large scale,.

B

Without without collaborative laws,.

A

B

There's a thing called collaborative waste. You know you.

A

Have competitive.

B

Ways right people.

A

Not working together or getting patents and not allowing anyone else to learn from their work. But there's.

B

Also collaborative ways which I think.

A

B

Situation there.

A

Is not a lot of people are really super good at it and because everyone is.

B

Proprietary, it's just impossible for people to to work like.

A

B

Just not how things.

A

Are done so? How can we do it work openly? So it's a skill that so I looked at your.

B

Notes on what you'd like to learn, and you said collaborative.

A

Development is a skill you'd like to learn, and I think it's a skill that many many corporations just just about everybody- will.

E

Will start to respect like it's already respected in software I mean that's a no brainer any software, but I think it will just transcend to all the other areas.

F

A

F

It does require.

G

Some basic skill sets it's not too hard. I mean the good thing is that the tools are there.

A

I mean we've got all the cloud collaborative.

B

Tools like we can conference now right now, we can edit.

A

Docs, like we can both go on a dock and.

B

A

And what's the limit.

B

To that, in terms of the number of people that can put their minds together for constructive work, I don't think there's there's any like if you have.

A

An organized process, you know where to put things others know where to find your stuff, you can have dozens hundreds of people, thousands working.

D

Collaboratively.

A

It does require just.

D

A basic level of understanding, but I think that level of understanding could be achieved then, just as far as the technicalities of the process in like you know, four hours, few.

A

Hours I mean it does, does um require.

D

Just a little shift of mindset of how you work.

A

D

That problem, I think, is quite.

C

Trackable- and we definitely want to test it out, so you and others like we're to do the major major event in august, like.

H

About august 21st or so the weekend.

A

24 hours major major sprint, where we basically.

B

Publish the entire business model and plans and blueprints.

A

And build instructions.

B

And on diagrams and economic analyses all of that related to the ceca home, so we can train others and we can continue a feedback.

A

Loop of constant development on that, so that's going.

D

To be a real experiment so like as you go forward with this, this is about okay, we're we're learning skills that we'll be applying we're. Not just talking about some theory of oh yeah. We can collaborate like that.

A

D

Are going to do it.

A

I

21St to friday.

A

uh If I look at my calendar, just uh I'm looking at the calendar march april.

B

July august, uh 21st, okay august 20 is gonna, be friday.

A

B

Sunday and we're saying: okay, let's get people to show up, I think the weekend is a very tangible short space within which one we have a big vision to solve. We're gonna solve housing.

A

We're gonna make affordable housing available to anybody, including the ability for you to get one of these homes from us or.

B

From other builders.

A

B

A big hairy problem, massive.

C

Transformative purpose that we're addressing second is we're going to create visible products, we're going to create a big book.

A

C

And price manual, and also like a coffee table book, which is going to be like a couple hundred pages like.

A

Mostly on inspiration and things, but also.

B

Get real design just solid real design, there's gonna be cad in there like, we can teach people how to do cad computer design and all the documentation necessary for such a project and.

A

It's and I think the you know to demystify how development.

B

A

uh It was um who, who said that that was, uh that was.

D

A

D

A

E

Inspiration, 99 perspiration.

A

Right so when you think.

E

A

E

B

That we can collaborate. A lot of the stuff is like you just need some ideas, some basics to go on.

A

B

That you just gotta do the hard work.

A

And that's why.

B

You need the numbers of people to show.

A

Up but the point is, uh if you share the actual underlying concepts openly, you can.

D

Involve many many people.

A

I

Breaking that task down according to modular design, uh methodology modular design, that's what software did they broke the linux.

C

Into a thousand parts and a thousand people could work on it at the same time. You know it's.

D

Modular breakdown, that's a that's a concept, so we can do that. The inspiring part is that with just some.

A

Basic skills, as long as you can learn.

I

A

What all the tech, all the know-how and technology is right, so why.

B

Doesn't this happen everywhere? Well because, like if you have some high power, guru or inventor or whatever they all kind of work in their corner secret.

A

B

Of times, there's this.

A

Attitude where oh yeah, it took me my life to solve this. uh You know uh a lot of.

B

People will think. Oh people are too dumb to understand this or whatever a lot of times it's that they can't explain it well to others. So, there's a lot of a lot of blocks and all kinds of levels from human psychology like how people can communicate, but but from the open source perspective.

A

The reality is learn.

B

Fast, learn openly share.

A

Everything, if it's a complex problem, you can break it down to many many parts, with a critical thing being that you expose you.

D

Teach others rapidly those very critical, essential nuggets.

A

D

The whole process to go forward- that's the stuff. You need the genius for.

A

C

Genius could also be collaborative. It could be that a lot of people.

A

Because they're getting fed all this best information, they can.

C

Conspire to to massive massive innovation.

B

Genius can happen from one person or it can happen for many people.

A

But that genius must be open source and it's really about cultivating open source.

D

Geniuses is what we're about here and that's why we think we can succeed and why the world, if it wants to be more effective in solving pressing world issues, people will pick.

B

Up on it more- and this will be a more popular method of development.

A

C

um So what are some of those tools, so maybe.

A

G

About just the nuts and bolts right now, so the first thing is like you got to have you gotta have people know.

J

Where to find your work, so uh I think I mentioned about starting your work. Log. Have you.

K

J

A

You've got that I know you've got it.

K

Yeah, I don't have access when I try to upload. You know the excel sheet. Sorry, the spreadsheet too,.

A

uh So you still cannot log into the wiki. I.

K

Can log in, but I can't edit it I tried putting in a test log. Also it didn't work it didn't. Let me do a test logging. There looks like there's some permissions or something.

A

uh So you got an account approved right so, but it you're not logged in you.

B

Can't well try it right now go to open source you, because this is critical like.

A

uh So we can start practicing this yeah.

J

Pull up the laptop give me.

D

One second.

K

Right here I was able to log in, but basically the page is not editable by me. I don't have permissions there. It basically said you need to set. You know. It said your browser needs to uh allow cookies uh from.

A

uh Okay, that's different! That's that's! In the timeline. I see.

J

A

E

That was the time sheet. The time sheet is.

B

A

There's some wait, but how are you able to do it before like you, it worked before for you somehow.

K

I know I didn't do any uh any additions to the workload. I mean how never uh made any additions to the work log.

L

Let me just log in.

A

Well because, for example, I see.

D

A

Hour log, the time the effort.

D

A

The time log it says, ashwin.

H

A

H

In like two test values, so so you were able to get into it.

A

February, 10 and 11.

K

Yeah, so I thought then I was showed up. Actually I thought they never showed up the effort lock yeah, because when I did that it never, you know it gave me a blank screen and when I tried to put up this spreadsheet there it says permission denied. Because of some you know.

K

Let me open that open source psychology.

A

But you did end up.

L

Those numbers did get logged in there. Like you, said tasks, seven.

A

Hours or six hours, yes,.

K

Yes, yes, uh but I'm not able to see them. I mean hang on sir. Oh they're actually come up sorry test test. One have come up.

A

G

Some so it's working yeah so keep.

L

Using it, but what I mean really: okay, that's a time log.

A

But what I mean below that, if you click, I want you to do this right now, like click.

K

Edit on, what's below.

A

That monday february 1.

K

Monday february, 1. click.

A

Edit on that and then type it, that's that's the latest entry. So let's go login.

H

I have a login so.

L

I will log in.

K

So so I say edit I get the edit, I click the edit link, so I can see the html page. You know what do you want me to change here?.

A

Yeah, so uh go back out. So today is: uh let's see the the.

K

A

February 13th, so I put a log.

A

C

February 13th, so I put an entry there. So if you refresh you can see it.

A

But that that's where you want to put in your spreadsheet.

L

K

Okay, I'll upload a spreadsheet now or if not, I can do that after the call yeah.

A

uh But embed it like there's a there's, a very specific thing: how to embed? How does there's a how to so.

D

Take a look at this link. There's a there's a page on the wiki called. Let me.

B

Paste it into the chat there.

A

But there's a page.

B

A

How to start a working doc, so the one thing is that yeah.

B

You put a link to it, but also embed it so that it's visible right there in the wiki.

A

And that way, like you.

C

Don't have to go to another, you know to google docs to see. What's in there, it shows up right in the wiki so that it's quite really quick to.

B

See like I can go to your log.

A

And then I don't have to be taken away.

B

To like google somewhere, that's it's right. There immediate.

A

B

Access to all the work product, okay, so.

A

B

D

A

D

Should probably so, just in general, like.

A

uh We want to be able to skip when you think about.

B

This we want to scale this process to as many people as possible. We have to think carefully about, like.

A

How we do everything if, under.

B

The assumption I say, there's a thousand other people working together right.

A

How do we make it that.

B

It's not like one second or two seconds or 30 seconds that everyone has to spend.

A

Extra together.

B

Because if you multiply that by a thousand.

A

You know like if you.

E

Did something on your log that you.

A

E

Documented something I have to go to a different site.

A

E

Scroll down whatever and find it.

A

E

H

Them 10 seconds to do it.

A

Right well, if a thousand.

E

People have to do it like, say it's a large collaborative problem.

A

E

A

Times, 10 seconds, it's like hours that you have just.

E

Wasted for the collective effort, instead of that, that time will go into development.

A

You have to be be careful about that. It's just.

E

Have that, in your mind, that kind of.

C

Awareness that you want to.

A

Provide the servant.

C

Like when you think about this, the the respect and service to others, and also in the service of efficiency,.

E

That you're, just as effective as possible when you communicate. So that means that's essentially the explanation for the immediate.

H

Link like say, you use your work. Log.

A

H

A link direct, so nobody wastes any time on that.

A

Getting getting to the answers.

K

So, for example, let me see if.

D

So to practice that right now, okay.

A

K

Right now, for example, if I had the access to your.

A

Your worksheet, I can click on.

K

B

Otherwise I have to go into my.

A

uh Email, so I'll do that if you can.

A

K

In fact that you are putting the first evil itself that once you complete the excel sheet put on the wiki as well, so I remember that, but maybe I was you know, I must have posted it on a regular basis, just to show the progress on a day-to-day basis yeah. I.

A

Didn't do that yeah and that's the uh that's the point about, and I talk about that in how to start a working.

B

Doc, so do take a look at that page because there's an explanation make sure that everyone has permissions.

A

And make sure that it's findable to other team members, um yeah yeah, just just read through that.

B

A

It's just a little.

B

Bit of insight.

A

On make sure that that anyone.

B

Can view it or edit it so they can collaborate. The point is that.

A

B

Don't do that like there's, potentially someone out there that can help you right now.

A

You know like for.

B

Example, the guys in indonesia or south africa or america that are working on it. They need to say: oh okay, hey, uh I can help you on this or maybe like they've, got some links for sourcing, but you I mean for india, it's gonna.

A

Be unique to you since they're, not in india, but so.

B

A

B

You want to get stuff out there as soon as possible for the purpose of maybelline collaboration.

A

So can you paste the the work doc, the spreadsheet, of your your materials, because what we want to do today actually is um we talked about.

E

C

Of what does it take.

A

uh As you load it up, what.

C

E

A

To understand the bill.

E

A

You have to know: okay, did you put it out there? Why don't you.

G

G

K

So I go back to my workload.

A

I

K

A

As well, there.

E

K

Log, so here it says new log entry. Do I uh copy paste the url of the google docs document? Well, that's.

A

The thing you gotta read the thing I sent you the chat box, yes, that you want to do that.

K

When you say chat box.

J

K

You made the gmail chat. Is it.

J

K

L

How to open this.

A

Yeah there's a bottom left there there's.

J

A

Open close chat.

L

Yes, sir I'll open that more options, yeah.

A

For now, just oh.

D

A

C

That so after people read that, but right now just paste.

D

C

Word in the chat.

A

K

Csrf verification failed request. Aborted csrf, cookie is required by the side from some particular form.

J

A

On I'm saying like in the chat box.

J

A

Can you please sure, I'm sorry.

K

Sure, I'm sorry I'll have to download and I'll do that, because I've got a very fast internet here. That's a week, I'm done with the desktop as well. So let's start meeting so gmail.

L

L

It's online lender of the.

L

L

K

So I have this chat box, I'm putting in the url there.

A

K

Within invite people security options, more actions start I I can. Actually you know yeah open close started says where I actually put in I'll put a high on the chat. In fact,.

A

Did you say just, can you type in anything into the chat just say.

K

Yeah, I just I typed hi yeah, hello, okay,.

A

No, where I don't add, not.

K

B

A

B

Into the jc.

H

Chat, which is the.

A

H

You go to the bottom left of the screen. There's open.

A

K

I'm sorry I got this 8090 copy, so this is.

K

Looks like I'm into a different chatroom.

K

There was nobody there, but I just.

K

So no no account needed so basically start open source psychology, I'm sorry yeah. So.

A

I don't know where you're.

L

D

A

A

You're already in.

L

K

Let's say meet and.

A

See because you're wrong on.

J

A

On a cell phone, where I see you but.

J

You just open up a computer.

A

You don't see it there.

K

On the ipad and the computer, okay, I can see on a big screen. I can see on a big screen.

I

K

A

Yeah and let's have a computer: let's, since we can.

B

Be working real time on some of these things and I want you to see how.

L

A

You want to use your laptop more than uh yeah ipad.

K

K

Open source, ecology is a start meeting, join it as.

I

A

Okay, um your video disappeared. There do.

I

You have a video.

A

You don't have a camera on that. Oh yeah, you do there, it is. I have a camera.

I

Can you see me nothing again, I'm just taking the headphones here.

A

J

D

The yeah I was going to ask you, so can you paste your.

A

G

Sure you know how to do that. Paste.

A

The link to your spreadsheet into the chat box and I have that yeah cause I'll share with you. So I should be on my drive.

A

Okay, I actually.

H

A

um All right, so I have it.

A

B

So let's talk about this so.

A

The idea there is thank.

B

A

um Yeah that takes me to do that. um Okay,.

C

So, what's the concept here, the concept is here, so we've got to build materials in front of us. This is the complete build materials for the 3d printer and the main task tab is the ordering list. So that's all the parts we order and then there's we three print parts which is in the second.

B

Tab but looking at the first tab: okay, so if you're say you're.

C

You want to get into production. This is the idea here. Is we want to start these enterprises all over the world with their localized supply chains?.

A

C

We go on, we actually start.

E

The one important aspect of it is.

A

E

Sourcing is one of the most critical aspects of any build project. You got to have the right parts.

A

The most secure.

E

Way to get to make sure you have the right parts is. If you can.

B

Can obtain them locally or even make them yourself the most.

A

Sure way is uh that would have zero dependence on anybody else's. If you can build.

B

A

B

Say the supply.

A

Chain crashes, you've got covid.

B

On a major scale, you can still.

A

Go on it won't matter um so part of the work that we do is. If we understand what the parts are, we can start.

B

Substituting them.

A

B

That's a that's an effort we can.

A

B

As a global effort make substitutions, that's.

E

Called recursion, we call that technological recursion, where we start building things in-house, but we first have to understand what are the requirements of the parts in order for that to happen,.

A

E

A collaborative effort we want to go down.

F

To okay say we're: we're.

E

You know using.

F

The rods for the 3d printer, you know the rods.

E

A

C

The main parts of the assist motion.

I

System, chrome plated rods.

A

I

C

The road we want to make them.

I

C

Do have the induction, furnace and metal infrastructure for metal, rolling.

A

C

Within the global village, construction set or the controller.

A

Which is a circuit.

C

Board, which can readily be done.

A

C

A cnc circuit mill and other open source pick and place machine.

A

Or even the metal.

B

Frame that we use right now.

A

We already uh we already print our own 3d printed.

B

A

For the 3d printer, but we can ask also what are all the limits.

B

Of what we can do in order to start substituting and making sure the supply chain is more robust.

A

um So we start with a good.

B

Understanding of the.

A

Of the build materials so.

B

You can take a look at the materials and just say: oh okay, I can get that part.

A

B

What happens if somebody doesn't have that part.

A

B

To make a substitution, you need to understand what are the critical parameters of that. So, let's start a document in which we document.

A

B

A

That's critical.

B

For anyone who wants to build this and make this work without, you know really be in in charge of this, so they do not fail in terms of quality control or producing.

A

A good product they have to have mastery of the bill materials, uh and that applies.

B

To everybody in the world who does this.

A

B

You're setting this up in india, for example,.

A

C

I'm not well qualified to help you like say you don't have something. You should be able to figure that out because you're closer to the sources around you, you can get help around you. So the localization of the bill materials is critical for.

A

um For the whole world and then how do we control that that kind of quality? If we do this in a distributed movement.

B

And then we say: oh well, this product in india is identical to ours and we can.

J

Certify that that's the case well, we have to have.

A

Some standards and common.

J

Understanding that makes that make sure that happens. So, let's start with a good understanding of the bill of materials.

A

Which is wrong.

J

Because it won't be just enough for you to.

B

Look at the bill, materials and say: okay, I get this click because you can be trapped as soon as click.

A

And the website is down and the product is no longer available. How do you make sure you get the right part? Okay, so so.

E

We're going to start a document right now, so this is actually um an aussie certification. You can read about uh actually there's an article.

A

C

A

uh Called I'm going.

G

To paste that into osc certification, which is which talks about.

A

G

Concept of what certification.

E

G

How do you guarantee.

A

G

Me paste that osc certification.

A

C

The chat box take a look at.

G

A

E

How do you guarantee.

A

What's known as.

E

We call that distributed quality control.

A

E

Have distributed production.

A

E

You guarantee it.

A

E

It's not really a thing.

J

That a lot of people know about because everybody's got centralized production. It's like you got one big factory.

E

Like okay say, you know, foxconn for uh apple.

A

E

Not distributed it's there, it's.

A

Like total dependence right so what.

E

B

When you do that in multiple places, you have to wait have a way to track it.

A

And uh make sure you've got the right page.

D

So it's a it's a novel topic like people. Don't.

A

D

Distributed quality control because they think it's impossible.

A

Well, it is quite impossible.

B

Because you can never get the same materials everywhere.

A

The only way you can start doing, that is, if you go down in increasing.

B

Your productive capacity, so that that you can make an identical part to me not because you can buy it.

A

B

Because you can produce it.

A

And that's the critical distinction, and that means all of us have to build up a higher capacity of.

B

Technological prowess.

A

Right, we have to have more skill and more capital, like intellectual.

G

A

B

Skills, more machines, more diversified technology.

A

Than just the kind of specialized way that.

B

A

Today that results in a more robust kind of a production ability where, in a small facility, you can produce many many different things. That's the whole.

H

Idea of the open source micro factory.

A

Basically, it's it's called flexible.

B

A

E

The specialization concept that most people today do specialization, but.

A

E

Another route that that's called flexible.

A

E

Specialization or.

A

More gent we're more generalized machines and higher skilled.

E

A

Produce all those things typical industries like dumb down the job so much so that an assembly line worker can do it. Well, if you talk.

B

About societally.

A

Not too great for the worker because they keep on doing the same thing.

B

It's not intellectually stimulating.

A

It wears people down, you know like.

B

Menial labor in a factory.

A

B

A thing of the first industrial revolution.

A

We still do it today we got to get beyond that. We got to skill people up, uh educate them, more open source, more machines that are flexible.

B

And open source that more people have access to it.

A

And then the kinds.

B

Of work that we do becomes more meaningful.

A

As well, it's more stimulating. It's got rnd built into.

B

It because you always have to solve new problems. It's just a different framework.

A

And it's the kind of framework we want to create because ultimately it distributes.

B

Power it solves for that big question. That's unsolved today, which is distribution of wealth.

A

That's one of the central.

B

Themes that we address in our work.

A

B

Let's, let's without further ado here,.

A

B

A

An admissible parts list: what are the critical aspects we'll start going through.

B

A

And uh we want to.

B

Get a comprehensive document.

A

B

Say these are all the things you need to know.

A

This is how you can substitute it. This is how you can well.

B

This, these are the properties. These are the substitutions possible and also, how do you go towards.

A

Making it in-house and what is possible to.

C

Make in-house and how quickly, how easily.

A

C

If you can make it in-house typically, that means.

A

More economic benefit to.

D

A

D

Capturing the value of that production.

A

Instead of throwing money out the door that money now keeps coming to you, so you, your business model, is much more robust, absolutely.

K

A

D

B

Like I've got some numbers to back that up like I I took, we call that so let me share a page called.

D

Technological recursion, which um technical law.

K

And very interesting work.

A

Yeah absolutely this.

C

I mean we're creating the new industrial system and you're part of it, and that's why anyone.

A

Who's watching this, we want.

C

To publish this, we want to invite more people because, as I said at.

B

The beginning, the only way this is going to happen is if enough people like us, are doing this and making it happen. There is no magic.

A

This is guaranteed to work. It's, it's simply a shift of mindset to collaboration and that's.

B

What we stand for so take a look at the productive recursion.

A

D

An interesting read because in there I say okay so say.

A

D

We're building a tractor or.

A

A brick press: well, did you know that if you don't just get the medal, how about you bring an induction.

D

Furnace into your own operation as a machine for melting metal.

A

And start from start scrap so say we we do builds here. We've got tanks.

D

I'm sorry, can you, please repeat the sentence.

A

You said induction induction furnace, so you can melt.

J

A

Right now, what does.

J

That mean, if you can melt.

B

A

You can take scrap.

B

A

And turn it into virgin metal that you can use again.

B

A

Profiles, whatever right so you'd, think well uh an average. uh You know. Machine builder would be like well, I'm not doing.

C

That in-house I can get get the metal from my metal supplier right.

A

E

You look look at my page, the recursion I discuss.

A

E

Happens when you start making that model.

D

In-House okay, what's the bottom line, what's the what's the actual sense of it? It's not just a nice idea. It's actually practical.

A

D

You look at the numbers. I just did a simple exercise to say.

C

Okay: well, what if we have an induction furnace where we can melt 200 pounds of metal per hour? You know that's a little induction furnace and we generate steel from it.

A

D

It turns out that, instead of paying.

A

Extra like steel.

B

Is typically like about a dollar a pound for steel, from.

C

The metal supply here, let's say.

A

C

Numbers that show that well you're, actually getting it down to more like 10 cents, an hour or 20 cents, an hour, sorry 20 cents or so.

H

You can look at the exact numbers.

D

But the bottom line is, if you count the labor and electricity and resources that it took you to make that.

A

I

Seeing that you are generating much more revenue in the house because you're not spending that money outside you're actually producing it.

A

I

A

I

B

Amount of return that you get from it is actually very positive.

A

C

A

C

Have to make this bubble of tractors that can actually and include more diverse production like the steel production in the house,.

A

I can make uh I can.

C

Still make the same amount of.

A

C

Too, and make more money but typically means you don't have that pressure to sell so many things, because you're making some.

J

Really good money.

L

Doing what you do already, so that's the idea that you basically start replacing the things that you would otherwise buy from the outside and making them in the house. Now.

B

Steel is a pretty radical example, because I mean that sounds pretty tough right to mouth seal and make.

A

C

Metal out of it.

A

C

Of a radical example, but you can apply that kind of thinking to many things.

E

Using 3d printing.

A

E

We have the right equipment to do so.

C

Like right now, we're not doing.

E

That we haven't worked that out.

A

E

Point is we can't so that's just an idea. We want.

C

To think about technological recursion, so that we can do.

A

C

Say it's all about robustification, a more robust enterprise model that is less susceptible.

D

To supply chain shocks- and that makes good revenue because it has more command of value. Adding.

E

C

Adds more value.

E

Throughout the process.

A

E

That means you're capturing that value.

A

E

Good for everybody, and we also focus on like, for example, with the steel example.

A

G

Line is you're re-localizing a.

B

Lot of the production process.

C

It's like right now. You know the cars in the junkyard. You know 10 miles down from us here. That's probably all going to china.

A

You know and then.

C

Coming back really inefficient, so we're talking about local, efficient.

A

C

Circular economy, close feedback, closed-loop systems.

A

You're bringing.

E

Up the community.

A

You're, making.

E

Better products because you're collaborating.

D

So I'm going to share this um with you.

A

Productively um then,.

D

A

D

Doc so I started.

A

G

A

A

C

A

And then paste, oh.

H

It comes all weird.

A

A

So I'm gonna erase that.

A

And then we can go.

B

Through each one.

G

So let's talk about.

A

G

Here we're going to basically go look at your.

A

Source, why can't I.

E

E

A

A

B

I'm able to actually.

A

D

Need to understand part by part, because even if you don't have like a single part like if you don't have the screw you're, not.

C

Going to be able to build the printer.

A

C

Each and every single part is very important.

A

C

Understand it, because what if that supplier didn't have it, and he has some other thing.

K

They actually provide they actually built 3d printers and they provide 3d printing services. I.

I

Wrote this part list with the kind of permission I.

K

Shared the excel sheet with them. Sorry, so they said now most of the parts. So what I'm trying to say is for me to build the first 3d printer. I think I can get most of the parts yeah. I will prove them all through these, so you know yeah! That's.

E

A

That's good um and it's still, you still have to know what all the parts.

B

Are so let's continue, so what is.

A

uh So that's 29 about 29 rupees.

L

Yep, how much is that.

J

How does that translate.

L

To uh a dollar standard for a piece, I think I had one I'll check the usda s3 imrs.

A

D

Is about a cent a little more.

A

D

J

K

K

72 rupees is a dollar and a hundred census or dollars. So basically, looking at you know, one dollar, seven cents, sorry 177, rupees, 75,.

L

Points yeah, yeah samples, let's get biceps.

A

So then you look at it and then so yeah. So let's, let's do this example on a bolt.

D

Like what are all the things we need to know about this bolt.

A

D

A

You look at the price and you say is that.

E

A

B

Question so first question: is that good would you buy it.

K

It's fine I'll, go ahead and buy it I'll buy all these parts for the first time no worries at all. I don't look at the password, I'm more keen on necessarily able to.

A

Okay, so yeah, okay,.

D

Well, let's understand a little bit more about the price. The first of the first thing is: did you sum up the entire bill of materials and what did you get.

K

I didn't sum them up.

A

So, even for that, like you want.

H

To say, okay, is that cool like okay? Do I.

A

H

I'm gonna make 100 printers. Do I want to buy this because maybe what if the guy has.

D

You know the next, you need like 50 of them, you know so say like 50 times 40. It's like 20 bucks and.

A

You want to make 100.

D

A

D

2 000 bucks.

A

F

These bolts, if you made 100 printers, that's that's a bit. You know, so you ask yourself well. Is that a good price once again.

A

So what I I would first say and look at the so.

B

If we have the blm of the.

A

E

The u.s, so you can go to, for example, d3d pro and you can go to bom.

A

And you look at first.

E

Thing you probably want to do is compare it to the us prices. We know the u.s price is pretty decent, that I've done some work.

A

On it to optimize it like, for.

L

C

In mcmaster.

A

C

A

Let's look at click on the link. Let me actually.

B

Share my screen with you, so you can see where I'm.

A

Where I'm going so, I went to mcmaster and I'm seeing 7.77 for 50., um so 777.

E

A

B

A

So, okay, so you you say so: you're.

C

A

Compare that first to existing blms like usa, well.

E

Right now we found out you're like two and a half times more expensive. Damn that's a lot.

A

E

Was gonna spend at two thousand dollars? I just can tell you you could probably spend four hundred dollars for the same.

C

A

Don't do it, but if it's just the first thing you're getting and you haven't really done the.

E

Optimization work, don't worry about it, maybe just get it, but I'm saying this is not cheap.

A

E

I I think I did some more work and I think I found stuff for like seven cents with you from the us.

A

C

Anyway, that's you.

E

B

C

A

Because you, if.

C

B

Make your numbers.

A

B

I

Up making sense.

A

You have to be able to evaluate how does the price compare to industry standards, industry standards you have to.

B

Go by is osc, that's we're doing it in america or maybe some of the other materials in other countries.

A

um So you may choose to proceed on it or not. It's.

C

Up to you, uh probably for the first printer, you might say just forget I'll just go with this. If I don't feel like looking for more because I only need.

A

um You still need.

B

Like 50 of them, so so, if you think that it's worth saving.

E

Over like 50 times, 40 you're, paying 20 bucks. If you think it's worth saving some money, then you can look for it. If you don't think it's worth saving money.

A

Then just buy it now. What are the substitutes here is that stainless.

B

Okay, so the next next.

D

A

You have to ask.

A

D

Question two: what is.

A

So you have to ask yourself at that time: what are the admissible materials um so.

E

Can you go with stainless? Maybe stainless is better, so stainless meets the requirement. The requirement is, we have to know what the requirement is. The requirement is.

A

You don't want it to rust, okay, so so that's the first thing: what are admissible materials.

B

You have to have a bunch of requirements for them, and it's.

E

A

No rust cool that means stainless zinc, plated.

A

Oh, that could work now. What, if.

B

You were in a bind.

A

And you get just plain plain black: I think it's called black oxide yeah.

K

A

Think that that ends up rusting like like.

G

You can look up. Does black oxide.

A

H

You don't know like you might want to do some research, there's black oxide rust. That's.

C

On the internet says.

A

C

A it's a mild layer of corrosion and abrasion.

H

Resistance, it will rust on you. I've seen it rust so.

I

So preferably you don't want to do it.

A

So one of the things you have to know is that black.

D

A

D

Go through a large number of kinds of.

A

Material coatings.

B

A

Common ones, so what you want to understand.

B

A

Is understand that pretty well because say you're in a particular bind you.

B

Need those screws they got just this one type of thing.

A

B

To answer is that going to be admissible.

A

D

Why I call it admissible parts list? Because if you have that admissible, if it's admissible.

A

And it's going to work you're not going to get.

B

Quality sure so the main criteria for screws is basically rust. Does.

K

A

Yeah but then you can say um in some cases you might say well would.

B

A

B

Is not great because plastic is a bit weak unless this this is only a one-quarter inch.

A

Plastic is not great, it's not good.

A

J

What you want to what you.

A

Want to note is do this. I think it would be called value.

B

Engineering, you can say: okay, you've got this one screw.

A

That's stainless this other one is zinc plated, but the.

B

Zinc plate is like half the price.

A

B

A

Acceptable, I think it boils down to data.

B

Like we could say.

I

We don't have that data, like I haven't seen any of my zinc plated, bolts, rust, yet.

A

I

E

Years, do they last and does it meet our criteria of lifetime design.

A

So I'm going to write that ask.

D

A

D

The material I'm going to make that a separate question: does that mean lifetime design considerations.

K

Perfect, the strength of the material also determines.

A

Because we know.

D

A

Stainless will not.

E

A

E

A

Takes x years to rest, I don't know so so you need data.

B

In that case, we would need data, but so far we haven't had any issues and so far admissible would be zinc, plated or stainless.

A

And you probably end up, I mean some.

B

Places it depends.

A

E

You are, but you might have stainless, be less cost less than zinc, blade or other way around.

A

E

Choose it by value engineering.

A

um So evaluate cost to performance.

A

E

Value engineering, so you see me typing in a doc.

A

Yeah so so the idea.

B

A

If you notice, in a meta level what.

B

Are we doing here.

A

We're actually.

B

Documenting this as we go so that everyone can contribute, and by doing that, we can create a document. Also I mean you can get into a lot of detail here. As far as.

A

What is good, what is better and what is best, and I'm.

B

Not claiming that we have the best.

A

B

I make this open is that other people can look at it. You get a million eyeballs on this and then you get to okay.

A

B

A

B

Needed to make it absolutely the best.

A

Because I think we.

B

Know it well or we know it decent, like what works and.

E

A

But what if there's other feedback.

E

That's just oh wow. This just works way better. It's cheaper, better, faster, that's, an absolute possibility and that's why we work.

A

Openly and that's.

E

Why we think we're going to get a.

G

Better product.

A

C

That's another level of why we share these documents and say we're editing this here, like.

E

I'm going to go into.

A

E

Let me show you this, because this is a.

A

E

Important point.

A

D

To show you what I do to this document, because I encourage everybody.

A

D

This, and so I.

E

Go into I'm in this document.

A

E

Admitting that I don't know everything.

A

E

A

E

But I want to learn faster and better.

A

E

If your goal is to learn faster and better.

A

E

What everyone else knows.

A

How do you do that open it to feedback loops? How do you do that? You.

E

Can, for example, do.

A

E

I

You go to share share this thing.

A

And in the link.

I

A

Anyone on the internet can find and.

I

A

Well, actually, I'm.

E

Going to go even further.

A

E

Going to say public, so anyone an entry can find a view, but also edit. It.

A

Just go ahead so that if, if there's indeed a bunch of people.

B

Looking at this, which is not you know right now, maybe a few people are going to look at it or maybe there's going to be a lot of people looking at.

A

It, but we know that in.

B

The future, when there's going to be a lot of people.

E

A

E

Is the the sharing this, so anyone can edit? It is a very practical thing, because what if there's a guy.

A

E

Knows the exact answer.

A

E

He has a chance to actually put that answer in here and you don't have to do it.

A

E

A

The best information.

E

In the world, just because you left it open for comment open for editing.

A

C

You might say why do we.

A

C

Vandalism, like people are going to mess up your.

L

A

L

Possible, but that's never happened and there's safeguards, because the document here has a version. History.

A

E

K

Is a version history which.

C

A

C

See the revision history and you see some revisions, but basically, if someone messes this document up, you can revert to a former document. So we find it better to keep things open.

A

And then correct it if we need.

C

A

C

E

Out and lock everybody out of the process, because the key thing is.

A

um Working openly means we open.

E

Up the process.

A

To feedback and work from others absolutely.

E

H

That and I share that document, so it's anyone can find and add it, so they can just because there's so many details here, like maybe there's somebody from india to.

K

Look at this video says: hey, there's.

B

A guy getting to open source 3d printers in india. Oh, it sounds interesting. They might want to collaborate with.

E

You or you might want to hire them in the future. They might be uh exactly who you needed or looking for.

A

E

Of course, there's going to be a lot of people that might not contribute anything they might be trolls.

A

But you just have to you have to police that yeah you have to you, want.

B

A

uh Open to to collaboration, but at.

C

The same time, if somebody trolls you you just.

A

Cut them out, that's a simple.

C

Thing you just either.

B

C

The document or block them out of a group or whatever, wherever that forum is like.

A

C

Were doing docket, you know work on a forum, then we just blacklist the person.

D

And stuff like that, so there's ways you can uh do that, but typically keep things open.

A

So on this screw thing, so um pretty much the cost to performance so.

B

A

uh Evaluated we.

B

Talked about the cost.

A

B

A

We talked a little bit about materials. You can talk about calculations like how do I understand this, like, for example,.

B

A

uh Calculations.

B

C

A

Acceptable well: here's where we get.

B

Into actual calculations and and.

A

You'll probably learn more.

B

About this as you go, but but the basic concept of.

A

Of compressive.

B

Strength and tensile strength, this strength call it the strength. You have to understand like how strong steel is.

A

Or how strong is plastic? Well, that's.

B

Called numeracy, that's like that's kind of like gets, it starts getting into engineering, but all it is is understanding.

L

C

A

How hard is steel well from working with it? I.

C

Know that that value is about 50 000 psi.

A

H

C

Pascals, I don't know mega pascals. I typically work in the.

K

Some quality of steel.

B

A

You have a thing called loosely speaking: it's called strength.

C

Specifically speaking, it would be tensile strength or compressive strength. Those are some of the two main things.

A

B

Tell you that those quantities are.

A

Comparable, like.

B

Tensile and compressive are typically comparable. You.

A

Can say, uh but I know that value to be like 50, 000., okay, well, that's cool, but that really doesn't tell me anything unless.

C

You really know what that number means.

A

um But you have to you kind of have to start wrapping.

B

Your head around what I call numeracy and that's the that's calculations.

A

In the back of your head, you should immediately tell me this screw is going to hold x pounds, but.

B

I'm going to teach.

C

B

E

A

It's easy: it's you! It's called back of the envelope.

B

Calculations just very basic first principle:.

D

Calculations which allow you to assess what works and what doesn't.

A

D

A whole field you can get into you can get into all kinds of calculations, but the good thing about calculations is, you can find a calculator for just about anything.

A

In the world on an.

B

A

B

That makes calculations or just that concept useful.

A

Is if you understand the basic principles.

B

Of what that calculation is describing, you have to understand.

D

A

Don't worry about like funky formulas and.

D

A

You have to understand the concept so.

D

For strength of a bolt.

A

This is a couple of concepts.

D

The first one is like.

A

The strength, the the pounds per square inch of strength, which is typically the compressive strength, which is quite.

B

Similar to the pencil pencil meaning when you pull.

A

It, how much can you pull it before it breaks compression? How much.

B

Can you press down on it before.

A

It squeezes like, like a strawberry and flattens, um so.

C

Okay, but let me just give you one one quick example:.

A

F

Is 50 000 psi about.

A

And that's a quarter.

F

A

B

The area of that is, you know if it's a quarter inch bolt.

A

Roughly speaking, you can call.

I

It a quarter inch, it's not exactly.

A

It's going to be less than that, but let's.

I

Say it's a quarter inch. Well, if I know that the strength is 50, 000.

E

A

B

A

B

Can I pull on that bolt before I actually pull it? I'm superman, I pull it, how much force I have to pull it for it to just come apart snap apart. What is that answer.

A

Can you tell if it's a quarter.

L

So psi you have to for that.

A

B

Is you have to understand psi pounds per square inch? That means the force.

A

A

That's a lot that.

H

A

H

A

Means that if you put 10 cars on that square inch, it would still hold those 10 cars and then the question to you comes okay. Well that bolt it's not one inch, because it's a quarter inch well real quick. Can you tell me how much.

K

Do I have to pull it before.

A

It falls apart.

K

uh You said: 15 50 cars; bm, sorry, that is 1.05 5 divided by.

A

First principles: you just told me that that bolt can hold like 10.

B

000 pounds or so.

E

A

C

A

C

That's that's right.

A

E

Bolt is very strong.

A

E

That leads to the next question. Okay, so that's.

A

E

Not gonna have like 10 000 pounds to hold on a printer like the printer is maybe 100 pounds.

A

K

Force of the head moving.

A

K

A

Like 100, possibly, why.

K

Are we actually investing in that kind of.

I

A

I

A

Factor of like 100, it's.

K

I

E

Enough, but it also tells you that if you use smaller bolts, it would work too, so you can.

D

So I can tell you right now.

A

D

What we're doing those bolts are way oversized.

A

D

Might say, okay, so this is like really.

B

Getting into understanding the build materials.

A

E

Next thing is: why are we using those quarter inch bolts there.

A

E

Way oversized ten thousand pounds, I don't need it.

A

E

A

Four four of those well like say to hold it. I know I use those.

E

D

To hold the axis.

A

D

Each axis you're gonna, have four of those bolts, so you've got.

A

Like 50 000 pounds at max and then you want.

D

To do a safety factor which you can say.

E

Okay, let's do a tax safety factor. Let's.

A

D

20 pounds whatever.

A

D

Does tell you that if that axis was like 5 000 pounds like those bolts would still.

E

A

E

Probably other parts wouldn't hold the plastic parts wouldn't hold.

A

E

Probably would bend all the way out.

A

It wouldn't really work but great you just.

E

Told me a very uh good insight. We can hold like ten thousand miles.

A

C

The point is: do back.

A

Of the envelope.

A

Example about fifty thousand um fifty.

E

Thousand psi for steel, okay,.

A

And now you can get the insights like yeah.

A

Is about 10 fold factor weaker, because I.

C

Understand some of the knobs.

C

A

Press 5000.

C

C

500 pounds and a square inch of.

D

A plastic can also have a plastic rod.

A

And it's a square inch that should be able to pull you.

B

Should be able to pull it like with.

A

B

Thousand pounds before it actually.

C

You will definitely be able to hold like 500 pounds.

A

C

E

Inch plastic rod.

A

E

That's actually coming close to what we need for the printer.

A

E

125 pounds.

A

Well, look at that. That's.

E

About that could possibly work.

A

B

I would actually say that if you're in a bind.

A

And you, you know.

G

B

On a desert island.

H

And you needed to build this 3d.

E

Printer, so you could print a boat, so you can escape to freedom.

A

E

A

B

Understanding so you connect calculations. So now I just told you well.

A

With plastic work there's an indication that it could possibly work and in practice, if you're in a bind, you can.

B

Try it or we can actually right now, because we found that the numbers, so the number for one.

A

uh One bolt is.

B

Roughly 100 pounds.

A

That it can hold roughly, we know we only.

C

Need to suspend an axis. That's like 10,.

A

Or maybe up to 20 pounds uh so.

D

C

Marginally good.

A

In which case we can we can.

B

Do some more thinking and say.

L

B

Might actually.

A

Work, how well does it work? Is it still like when you test it in real life, it will tell you the truth or you can.

E

Take some measurements in real life.

A

But you can say that.

B

Yeah plastic may work and for this reason we might say.

A

Why don't we 3d print our bolts.

A

And there are plastics that are way stronger than 5000 psi.

A

So if you understand.

E

The bill of materials you have just concluded.

A

We can possibly 3d print bolts for the 3d.

B

A

That's important because.

B

That means that might be a r d question for your branch in india.

A

It could be an r.

D

D question: for.

C

Anybody on the team.

A

C

We're identifying.

A

I

Ways to innovate.

A

Because we understand.

E

The bill of materials, so that's the point, calculations summary do them.

A

They give you insight.

A

On possibility.

D

E

Part substitution.

H

And if you talk.

A

About part substitution, technological recursion,.

H

In other words,.

A

H

Is making ourselves.

E

Okay, that's important.

A

So I'm gonna put a link there actually to the technological recursion. Since that's the word, that's gonna come.

E

Up a bunch because it's a.

D

G

A

K

Productivity regression as well. I think that wasn't the context of that sorry yeah.

A

Exactly that's good you're.

G

Right, productive, recursion or technological recursion, um some term. That's that says it's. I don't know what the standard.

E

Term is maybe somebody can help feedback, but I think they call it a vertical integration, maybe because some people by vertical integration they.

A

They mean, uh including some of the more productive.

B

Functions in the business.

A

B

Other words, you, you add more branches to your to one. What one business does.

A

E

Different words, but I haven't really found a good word for this concept of where you start making parts in-house like.

A

E

Sure there's maybe someone can just elucidate that for us, but I haven't really run into the.

A

Good work for them: um okay,.

B

Now the next thing.

A

B

The next question is, we kind of implied it.

A

A

Calculations um so so just to review. We.

D

Just did some calculations. We talked about the cost to performance ratio. We talked about lifetime design. Is that really lifetime design? What's the material that's admissible? uh First.

B

Question is like the price I mean, because the price is going to vary all over the place, whether it makes sense or not, because you just don't buy it just because you found it. The first.

A

Thing and then another.

A

From the osce.

E

Perspective and perspective of local economies, the technological.

A

uh Making parts a.

D

A

D

Are the possibilities.

A

um So we just said.

D

A

Potentially 3d print.

D

A

D

Potentially we can say: okay, we've got this printer, we are running a successful business.

A

We say: okay time for r d. How do we make it better? You might say: hey.

B

uh Let's try these bolts that.

A

B

A

Mib-1 might be an important thing to do, or it might.

E

Be just a thing that we just say: no, we don't really do that.

B

Do that just just if you don't have any any other options.

A

B

You can say it's.

A

It's good for experimental machines where you then melt it down and remake more.

B

Plastic filament out of that part, because I can recycle.

E

It so there's different considerations.

A

E

The kind of thought process you have to talk about for every single.

D

A

D

Could go through it.

A

And what we want to do so, as you see.

D

J

A bit of work there, but maybe what I can get you to do is for you to.

A

Really like try to understand, based on.

B

This logic that I presented it to you.

A

Try to see if you can fill in those questions for more of the parts I can what I, what I'd like to do is right now is I'll. Tell you some of the key things.

B

Like from the parts that we have so I'll start.

A

So that's the screw right there. um Let's.

B

Just go through a couple of them.

A

Like a few few parts just to understand like the key parts, let's.

B

Talk about so slide, I'm going to duplicate slide.

A

um So the first part was the screw.

A

B

Part, we know we have rods.

A

Right: let's talk about the rods, so let's go through a similar logic for the rods. um So let's take a look at what you've.

C

A

D

You can actually start.

A

uh You know telling me so rods, let's.

G

See where the rods here is uh the first one is the 964 you're gonna change that I'm sorry you're on the first line.

A

B

So that's one meter rods.

A

E

Hard chrome plated.

A

Yeah, that's the best thing you want to use hard chrome plated. That's.

I

A

B

What is it for? uh One.

A

A

B

A

D

B

That's a decent price like.

A

If you look at.

A

What we do eight millimeter rods, we get it so actually, what's.

B

Admissible here, like the dimensions.

A

um The ones we get are not great, because this kind of.

A

E

To do, but that will rust.

A

So it's not good, but I can't really can't really find good source a good source for chrome.

B

A

Hard steel rods- and I said: okay, that's.

B

Admissible as long as you keep it oiled.

A

But it's not really the lifetime.

B

Design you look at look for so yeah. I would say in the order.

A

Of preference, you want to start with.

B

Absolutely the hard chrome plated.

A

A

D

A

D

Hard chrome is ideal.

A

Stainless would be good, hard, chrome sure what.

A

D

B

Ideal material is what's acceptable, I mean if you're gonna buy, you can do.

A

You can definitely do other kinds of uh steel.

A

A

Steel will rust not ideal, but.

A

D

A

A

And in use it will.

D

I

A

But if you want the number one pick use the chrome.

B

E

Because the chrome doesn't rust.

A

Now, there's a one.

E

One thing about american versus.

A

uh Versus like which you have eight millimeter, eight millimeter and five sixteenths inch equals seven point. Nine.

B

Two millimeter.

A

E

That means is that so 7.92 millimeters means it's got like.

A

C

Discrepancy there.

A

C

Seen the difference between.

A

8 millimeter and.

B

7.92 millimeter.

A

E

Do rigorous testing we might be able to see a difference, but that would be some.

C

Some data point to.

A

C

But in america what I'm saying that is: there's a lot of 516's.

A

C

You also have imperial.

A

A

Yeah so 792.

B

A

Forget about that some on page two of the working doctor.

C

B

A

Be too weak? Well, maybe there's some other stuff like um there's. Probably there are, there are probably other materials like ceramic.

A

Or like fiber reinforced super hard plastics that might work, but it probably might be expensive. So you have to look at.

B

All the properties like.

A

You'll probably get like super precise ceramic rods, but they'll probably be.

B

Very expensive.

A

B

Again, you have to look at ceramic which we haven't.

A

We haven't ever assessed ceramic and it's not a point.

B

But so just stereo be a research point like. Can you actually find rods that are ceramic that will work.

A

And they maybe.

B

Have the advantage, even over.

A

B

Types that they might be higher temperature, for example, for some applications.

D

A

So we're getting like down kind of down the rabbit hole of higher performance functions.

D

K

D

Of beyond the scope, but.

A

D

Ask that question.

E

B

But in the meantime you got chrome rods, great, so we're saying.

A

About six dollars per meter, if.

H

You compare that to so, if you, if I go to real quick to chrome rods on amazon.

A

D

Like the first thing that comes up.

A

D

A

D

Mil or say, 500 millimeter wrong.

A

A

Two pieces in other.

D

Words the same as yours,.

A

Which is adds up to one meter.

D

And it costs 20.

B

A

Now six dollars is pretty good. You you guys.

B

Got pretty good raw sourcing.

A

There it's way better than we can do here, like I just haven't, found any.

F

Decent sources.

A

Of chrome rods.

K

Yeah, but for the other components I think my prices were comparable to the u.s prices. They were thought it should be cheaper here, but it didn't turn out to be. Unfortunately,.

A

D

K

A

If you look at those chrome rods that you you've got, um do you know.

C

Where they're made by any chance are they do they make them in india or they come.

A

K

Usually we get a lot of made in china and I saw the components made in taiwan stuff, it's usually important in bombay, which is mumbai and from where it was distributed to hardware stores in south india. So I.

A

Yeah, it's probably if you much closer.

I

To the chinese sources, you might get much better rates there, but.

A

I

I don't really understand fully the.

A

I

Rod situation because I haven't.

A

um Unless I think you buy like a real big bulk from china, there's just.

B

Nobody in the united states that makes them anywhere comparable to that kind of cost.

A

Whereas for other.

B

D

A

D

Are resources for chrome rods? I really haven't seen it.

A

D

Be one of those research points where I would have to say: okay, let's look at every single manufacturer and go through thomas register, which is do you know the thing thomas register.

A

D

C

A

It's an industry directory in the united states, um but yeah. If you look at.

B

So, for example, if you look at chrome rods,.

A

At mcmaster, I think they're, like.

A

Chrome-Plated hardened rods, they're gonna, be well first of all, that's too large.

A

So let's look at metric. Eight millimeter.

A

D

For for three for uh three foot lengths, they're 17.20.

A

B

Car, it's basically a meter, so you've got six dollars. Yeah.

A

That's three times um three times.

B

Better and where you are so that's.

E

A

um You have more.

E

Access to a critical component- that's that's very good, so I would just wouldn't be shy about buying that.

A

C

Lifetime design, yeah the the chrome that means lifetime design- that's pretty much. The destructor will last forever uh cost to performance ratio.

A

I mean I'm not sure.

D

What to say about.

B

That calculations.

A

F

What's a question.

A

F

Calculations, there is one question that becomes important.

A

And I would say, calculations in this.

A

Case, how long can you make an axis.

A

D

Do you have any feel for that? How you would go about solving that, so you got these chrome rods.

A

How do you know how long they could be before they just.

B

A

They just fall like right down, they're, just not strong enough, um so.

C

That the the logic there is okay, you've got a certain length, it'll be so strong, but the longer you make it.

A

The easier it will bend at the middle- that's just basic first.

B

Principles so then the question.

A

Is how long before.

B

You that happens.

A

B

To do that is called beam, deflection.

A

E

Find the beam deflection calculator online really easily.

A

E

Say: okay, if I've got a rod, that's made of chrome steel.

A

E

Is going to have certain psi.

A

E

Again, the compressive and pencil strengths.

A

The the particular.

B

A

You could do that. You can find.

B

Out how much it will bend, but there's calculators on that.

A

So, let's, let's go to one real, quick because.

E

Actually, we haven't looked at it, I'm just asking asking this right now, because it's a thing that when.

A

E

Really understand the bill of materials, we can.

C

Basically, before we go and do any builds, we can.

I

E

Okay, the maximum length of an axis is such.

B

A

B

I have to take other measures such as go to.

A

Thicker rods go to maybe.

B

A

A different material.

B

That's stronger than chrome because they you can get it.

A

uh Then chrome, steel, um you can.

C

Multiply the rise like make multiple axes, because our system is all scalable.

A

C

A

C

Question is: how long can that axis be and.

A

C

E

C

E

C

Deflection calculator.

A

C

Go to um I have that on a wiki, so there's a.

A

C

Deflection calculator.

A

B

Lot of these things as I come across them, I just.

C

A

Up online, uh so here's one that you can go on the wiki and google and search for that or you can just go right here.

A

So take a look at that link and you can do that yourself so so.

B

Here you can do.

A

It calculate the deflection for shapes.

I

So, first of all, you got to go to a round round shape so.

C

Beam deflection for the round, which is.

A

A

I'll share my screen, so you can actually follow what I'm doing here.

A

So I'm at this thing, so this is.

D

The bottom one here that's.

A

That actually shows this, um but let's.

E

Do this so length is going to be okay, I'm going to say first of all, what's our problem statement like I want to say: okay.

A

Say I have a two foot or like uh three foot.

I

A

We have built a printer.

B

Of three feet and it works.

A

Somewhat but let's get, how much will it bend in the middle? Because if once it starts bending.

E

Too much it'll just not do accurate prints.

A

E

A

To say how much can you allow it to bend before it starts to wobble enough that your prints start looking messed up.

A

Yeah well so, let's take a look at.

D

12 inches, let's say uh 12 inches beam deflection means that you have a beam and it's supported on one end. Well, this is a beam supported on two ends.

A

So 12 inches here would actually correspond to an axis supported on two sides. That's.

C

A

C

That makes sense to you so basically evaluated as a 24 inch axis would be like a beam supported.

D

On one side and you're you're, seeing how much it.

H

Will bend at 12 inches.

A

C

About it, that's kind of logical there, so, okay diameter is how many inches well, it's 5 16 inch. So that's.

A

C

Eight millimeters, so I would do- is eight millimeter two inches.

A

And that happens to be.

C

A

0.315 wall thickness no.

I

Sorry, this is round two beams.

A

Solid round beams, this is where I need.

B

A

B

Round beams this, this was round two beams. It's not a tube. It's a solid rod.

A

B

K

Inches diameter was point.

A

What was it three four one.

K

A

E

So this is the thing this is. This requires our insight. What kind of force are you gonna have in the middle of the rod.

A

Well, the force.

E

There is going to be largely gravity. It's also going to be inertia of the thing moving around, but gravity is the first force you consider so the.

J

First principle: approximation there is okay, we've got the.

A

J

A

We've got the rods the weight of the rods themselves. We've got.

B

The entire gantry that's moving up their.

A

Helmet, it's it's going to be around, maybe like, roughly speaking, it's going to be a few pounds like maybe up to I.

B

Don't know like say around five pounds, let's say.

A

B

A rough number we're just getting rough estimates here, because I can tell you that the.

A

Printer head is gonna, be about probably like.

A

One kilogram, okay or so so this is about.

L

B

That all together.

C

It's got a heavy.

A

Stepper motor on it's about about five pounds.

B

Okay, we say steel.

A

Now it doesn't get yeah, so this here doesn't really allow you.

B

To go anywhere.

A

Rather than steel, it doesn't say, like chrome, steel or whatever.

B

A

Or super strong steel, so steel would you'd have to probably look.

I

A

D

Value are they using for steel but they're going to be using something around 50 000. So we calculate okay.

A

Bam deflection.

L

Is going to be.

A

A

From five pounds it's quite a bit.

K

Point two is not advisable.

A

Sorry yeah! No, so, according to this basic kind of a calculation.

A

That would not work, but um then you start thinking about.

E

Okay, how do I make it work, so this is a 24 inch axis. Well, first of all, you got to remember that you've got two rods. There.

A

So you actually.

E

Got to take this and divide it into two, so you got 2.5.

A

So I actually have half this thing um well, but actually.

D

A

You can because.

D

We've got two of those axes.

A

There's another.

C

So if we talk about.

F

A

And I'm talking about one of the rods on the y-axis.

F

A

Axis that moves there's.

B

Two axes on the y.

D

A

E

I can actually say like.

A

E

This is not admissible. It's about.

D

0.1 inch, that's like it's wobbling, quite a bit.

A

K

D

A

1.25 to see if I'm in a ballpark, yeah 0.05.

E

So you kind of get less and less that's 1 20th of an inch. But that's that's a bunch of minecraft. You want to start getting down to.

A

E

Admissible things is 100.

B

Microns, because that's kind of like.

A

Around that area is where you want it to be good, um like the accuracy.

B

Of the 3d prints.

A

H

Into some of those figures, there's you you're getting into like a fraction of a millimeter.

A

Now point: zero: five, so you gotta do better than a fraction.

B

Of a millimeter.

A

And a one millimeter is point zero four inch and we're at so we're at about, like one millimeter deflection.

C

Here, well, it's getting there so.

B

A

B

This kind of tells you that yeah, if you have 24.

A

Inch as far as the.

B

Travel distance.

A

Yeah, that's pushing it so well. What about how well would it work for, like you know,.

B

12 inch long axis, which is right now we have a the small printers, have eight inch by.

E

Eight inch.

A

So that that means.

E

A

E

There you definitely it's 0.006.

A

A

Oh, that's 0.15.

B

A

B

A

C

That's kind of in the ballpark there so.

A

Yeah, so so, basically um we're saying that yeah we could definitely do like 12-inch rods and there's. This is just kind of like.

B

Really general here, because you don't know the exact.

A

Steel thing, steel um kind of steel they're, using maybe the chrome mods.

B

F

Better than the steel.

A

Value they're using here because.

D

Because I mentioned 50 000.

A

H

The first thing I look is like psi of.

A

Chrome rods, completed.

A

um Chrome plated steel.

C

A

C

Chrome plated steel. Here they say: yeah they're, like 75 000, psi, 85, 100, 000.

A

C

We might be doing better.

B

Than what this initial engineering thing.

A

Here is telling us, because steel is typically around 50 000, so.

B

Maybe it'll work, but the idea.

A

There is generally like calculations here for the rods. um The first thing is you're, going to say, can't do like two foot is with eight millimeter rods essentially, but do calculations.

D

Do beam deflection.

A

Yeah yeah, what was.

K

Your question: if the question.

K

J

What the underlying material is.

A

uh So I didn't read closely what that means.

B

A

B

This is actually that's the type of steel. It's called 1045.

A

Or 1050 type of steel, so those steels are harder than the mild like mild. Steel is 36 000 psi.

B

The kind of stuff you use to build tractors and just a very common.

A

Steel, um that's uh carbon steel that we use for building everything.

B

That's 36 000.

D

uh Probably the engineering guys, maybe they're using 36 000, I don't know they don't specify what steel they're.

A

Doing um unless you maybe dig.

B

Into that website they might specify somewhere.

A

E

The fusion idea for calculations you have to you basically want to ask yourself beam, deflection.

A

On the rods, and that's that uh making parts in-house yeah we'd like to do this.

B

A

J

K

A

K

Once we have the induction furnace, but that's I saw your article on that. The tire paralysis thing you are saying of higher temperatures. I'm sorry, maybe.

A

uh Yeah, there's uh that's different, so induction.

D

Is a particular way like the other stuff uh you're referring to, I think, is uh there's.

B

Two types of ways to make melt metal one is by electricity. One is by.

A

E

Burning like flames.

A

E

Are two main ways to do it, but the thing is about.

C

uh We want to go to induction, that's electrical highly precise and controllable.

A

C

A

Cleaner smaller size, uh that's.

E

Why we have the induction furnace? In particular, you can do that with a flame.

A

E

That's a much more brute process, brute, if you can say.

A

um The induction.

B

First is much more.

C

A

D

Of a process, it allows you to get much more.

C

Control over the process, so that's why we're saying induction.

A

Furnace but yeah induction for this is.

G

Like the induction cooker right.

C

Which you use in the kitchen.

A

And different frequency yeah I mean.

E

You can use that kind of you.

C

E

On ebay, you can get these tiny, it's actually really cool. These tiny induction heaters are only like one kilowatt. You can get that on ebay. You might want to play with that. That's probably really cool. I never touched those things yet.

A

But that's called open source power, electronics.

C

Once we figure out the electronics behind that.

A

We can build.

C

Whatever size of furnace, we like.

A

And we we connect that to our off-grid photovoltaics and you can get free cooking of steel into into virgin.

G

A

Yeah, fantastic. That would be great for.

C

uh Bootstrapping, an economy somewhere.

A

C

uh Where do we want to go for now, so how far.

K

Materials, the first time it's going to be very easy because, in addition to the websites, there's a company here that build city printers I'll spoken to them about the parts, so they will give me the parts. Otherwise there are hardware stores where I can buy as well. The robotic parts here building is not going to be a problem. I can start to know: okay.

A

K

See how fast you.

D

Can identify the next uh as soon as you got to just.

A

Email me so, let's, let's do this complete the the bill. Materials second part is the dock. We just started you can edit it it's editable and go through this kind of uh an analysis. This is.

B

This is rod so maybe put in a picture.

A

And kind of go through these, these analyses for each part as.

B

Much as you can.

A

Like just start thinking about it like how do I know this.

D

Is the right thing.

A

Like if you're going.

D

To be teaching somebody or.

B

Starting your enterprise.

A

B

You know, of course,.

A

You get a lot more with experience, but for right now the important part is. We are learning and.

E

Documenting collaboratively right.

A

E

Spend the time as you go through this just documenting your.

D

Thoughts on this and I'll help on this doc.

A

D

That we get a very exhaustive.

A

Treatment of how you truly understand the bill of materials and then what.

B

I can do is I can also do for certification. We have like a basic exam and I'll be like okay. Here's our main questions that you have to answer.

A

B

Be a form that you can do online and then get certified to say that okay, I really know the bill of materials. It might also have some thinking, questions in there that are.

A

Like calculate.

B

This, like is this part, going to be acceptable, so you have to understand not only like.

A

B

Want to go through these this logic and reasoning, so that, if I ask you a hard question about the bill of materials, you can answer that and gain leadership.

A

And a skill to teach others.

K

Is it okay to make mistakes while putting up documentation or if they're I mean.

A

Yeah, of course that's that's the thing I didn't mention anything about it, but absolutely um that's what I'm.

C

Saying like this collaborative process is largely a psychological mind. Shift yes make all.

E

A

D

Worry about publishing early and often the point is.

A

It's a live, live doc, it's not fixed in stone, it's editable. It doesn't cost anything to improve it. We should share it with others and like what I would do right now is.

B

Go to the oc workshops, facebook page and say: hey, I'm working on this document help me.

A

And you'll probably get some feedback so start involving others start talking about. It start blogging about it, telling your friends and get people around it and the main.

B

D

Is yeah make mistakes because that's how you're going to learn? That's.

A

D

H

D

Of self-esteem that you can say: okay, I'm open, I'm collaborative I'm going to be vulnerable, I'm going to teach others, you have to make mistakes. So thank you.

K

Hello, and secondly, uh is it okay to first start building the printer and then come back to the you know, or the material kind of the buildup material strength and assessing you know way back the technology and expression thing, because the way, maybe uh I'm sensing a test, build a first level, then records to the next level. Then records to the next level. Yeah.

A

That's a that's a way too. You can do that. Certainly.

B

Because some people can just learn much more, and I do believe that, like.

A

E

Now have the appreciation of documenting as I go along, because I got the experience already.

A

E

No, I did not do that. So, as you start yeah, you can do more bills and less documentation.

K

But you want to make sure that you come back to the documentation. Don't forget about it. Definitely absolutely.

K

And actually put up a small presentation on facebook once I've done this with you every one of the 60 items, because I am new to a lot of these parts right from you know some of the circuits that I used. I thought I would actually give others a basic introduction, because the way I learn is so take each of those 60 parts of the build up materials and give up maybe a very simplistic definition or example, or understanding to something else. Yeah.

A

Yeah, it's essentially a technical writing thing. It's like okay! Here I'm describing to you all this stuff, I'm I'm educating you! I'm learning in the process.

B

Like as I'm doing this, I'm learning.

A

Myself and there's a lot of information you can, you can gather like if you.

B

Understand the parts in the 3d printer I mean there's so many different parts, so.

A

Many so many subtleties and I mean there's electronics, there's mechanics, there's materials.

B

There's a lot of different stuff there, so that in itself that's a really an intensive kind of a documentation.

A

Thing if you you.

B

C

A

Somebody a you know.

C

Like a chemistry lesson, a physics lesson, an engineering lesson, a structural engineering lesson and.

A

C

Programming, it's all in there, so.

A

C

Why you want to involve as many people do, the document, but.

I

C

With the build materials there's a lot of information that goes to it.

A

And once you know it you, you can learn a lot. So so yes, it's worth spending some time on, like between materials, computer, aided design like if you have those two perfected. You have just about all the information how to how to build it.

B

Like so, the cad should correspond completely to the bill of materials. Once you have a complete build materials.

A

And you can from there for from the cad, you can get complete pricing in the future like if you've got a programmer guy. He.

B

Can take the cat and put in automatic pricing mechanisms within freecad.

A

um It's all kinds.

B

Of stuff you can do, but if you can reconcile the build materials with a full cad, you can do everything you can do instructionals animations of how the things go together.

A

B

A

Team that can work on it. That's part of what we're going to do in august. We're going to get this huge team just working on all that all together.

C

A

The whole manual like really get it to a decent.

C

K

But then one more question in august uh is the requirement to be on site in the unit.

A

K

Is remote and then the.

A

On-Site is september 1st.

K

Through november.

B

31St, so if you can make it you're invited to that.

A

B

C

We're going to have a lot of people here, it's really going to be about collaborative development and design. It's going to be crazy. It's going to be the biggest thing we've ever had.

A

So that's going to be good.

A

Excellent, yes, so.

D

So continue on building materials continue working on the dock and, if you can like, if you can spend any time on it, but if you want to just get right into the build just finish, the build materials I'll work on I'll continue working on this.

B

Dock as much as possible anyone who's watching it.

A

Feel free to go into that dock and you know clean up right now, it's two mere pages by then it should be a very.

D

Nice, clean educational document, that's well formatted. We just started it.

A

Yes, that's how it works.

D

You just start and go forward.

A

D

Really good and something that a lot of people can get a lot of value because, after all, if you understand it, you can build a 3d printer.

A

So yeah okay sounds.

E

A

I

Else until next time,.

A

We can communicate on the internet and go forward.

K

In fact, what I'm going to do after the call is, of course I'll get back to the document. The first thing is that their office instead of saturday, their office is open today to make a global company with these bills, I'll directly go to them and just have a you know: casual chat, yeah, yeah, absolutely.

A

All the materials there um I think, like 24 hours, I would say twenty four four yeah. That's a lot of.

C

Time like like yeah just building 24 48,.

A

C

Can build one in about eight hours or so.

C

A

It in eight hours a beginner like if I have a kid eight hours, no.

C

Problem, um I could probably do it about six hours, one building that for the first.

A

Time, if you have the complete kit 24 hours, but if.

C

You got to prepare some of the parts.

B

Too, that will take you a little longer.

A

B

A

You once you have all the parts 24 hours. Is it good for novice? I.

B

Mean this the point.

D

A

E

Surprising, but once you.

A

E

Doing this you'll find that it's doable.

D

And it doesn't take as much time as you think, but you do have to.

J

Have I mean it's hard? It's it's long work. I mean.

A

J

A

Is still a lot of time, not a lot of people.

K

I'll give it I'll give myself a week.

A

Four hours but 24 hours of actual work so.

F

You're not going to typically do that in one day.

A

It's three days, you know three.

F

I give up three days and eight hours.

A

F

Hours of actual build time.

A

Yeah, I thought I'd give.

K

Myself a week, if you don't mind, yeah.

A

Like a week would be a good.

K

Estimate, if you have.

J

uh If you have all the materials.

A

K

Yeah to begin with, typically, but as you say over time, I should improve. You know: people faster yeah,.

A

And the first time I mean, if you have no experience yeah, you can.

C

A

C

Towards the longer side of that, which is not three days but six days, meaning like 48 hours,.

A

Perhaps uh I think I've heard people.

C

Say like a lot for our printers, like some people are taking like 20 hours, I think.

A

C

Some are building it faster. I actually don't have good data on that. So actually we should start collect actually.

A

You brought up a good point. um The one.

D

Thing I do want you to document is.

A

Put all your hours into the time graph like how, if you can start a spreadsheet where you you are very rigorous about it. If you can have a camera, that's doing a time lapse, so you just have it there and then you.

B

Can just upload the video and then we can tell it, took you exactly this much time to.

A

Do it that'll be good? Let's actually do here right now, like.

B

We're doing the house work.

A

Building the house, I have a time-lapse camera for several and we're getting real data, so we got to get real good at feedback loops and data. That way, we know.

D

Exactly how much it costs us to produce it, so your business model is accurate.

K

A much and one request may be the first time around I'll. You know prefer to do it slowly and you know, and just to understand.

A

Shouldn't bite well yeah, but but I'm saying even as you do it slowly, we can say.

D

Okay, when you have absolutely no time pressure, just leisure, complete leisure, that's still a data point.

A

D

Okay, if you're not in a hurry.

A

You're learning this is a build and learn process. This is.

B

How much time to do it.

A

B

Could be, this is just when you build it, or this is just when you try to optimize the build, so all those all that data.

A

If you can you'll help us, if you, if you uh take that data down because yeah I know you're learning, it might be like. Oh well, what's the point of collecting that information, but.

B

The useful part is well: how long does it take you to learn.

A

That's an important data point. We can.

D

Say: okay, an officer completely.

A

No skill in this took x hours to actually learn.

D

A

And then build it, so it's good information to have yeah feedback loops.

D

J

Going to keep talking about feedback loops, because that's that's! How we're going to improve.

A

The product over time to make it the best we've got to have the feedback.

K

Sorry, the only fear is somebody ends up. Judging you, you know you take a lot more time. You know.

A

Well, that's the.

C

Point: that's that's the thing, that's the kind of psychology we have to develop to grow as individuals. We have to gain that kind of confidence that says.

A

Well, first of all, I'm teaching you I'm.

C

Being open, like that's, called uh developing a high level of self-esteem where it's like, no, it doesn't matter like. I know what I'm doing like.

A

um When you feel confident that you're providing value like treated, I think maybe one way to treat it is um as you're. It's not like. Oh I'm racing to the building. It's like I'm actually.

C

A

As well, it's not don't worry about trying to like get away from that judgment, but you'll get.

E

That people will be like.

A

E

You start publishing stuff. Of course people will start spamming on you, because a lot.

C

Of people like to whine and complain right, but you just have to.

A

Be in a safe environment to do that and that it's called that you can call.

B

It this is data collection. This is not like. This is not my slow self working. This is we're collecting data on how much we can, just by saying that that's a useful way to say.

A

To like fight off the the trolls who who would be like judging you on, oh it's taking you a long time, that's not what it's about it's about! Communicating.

B

The learning process.

A

Which society's not used.

D

To that people don't like to share that kind of stuff, so we're creating culture, we're creating a culture.

A

That says: hey.

D

B

To do that and.

A

We're actually gonna collaborate.

B

We're gonna teach.

A

People the only way we're gonna do. That is, if we work openly that's.

D

That's the kind of mind shift.

A

That we wanna have and that's.

C

Powerful, like once, you show that kind of example.

A

C

A

Because then, you're.

C

B

Transforming society from.

A

This competitive, like look at me like individualistic.

B

A

To hey we're all.

B

In it together and that's that's the big message.

A

E

L

A

Okay, so that's.

J

Until next week, then yeah and feel free to communicate on email and.

A

J

A

Stuff, let's do it by the way!

A

So let's do that on every this time works for you, I'm assuming! So let's do that on a friday for you. So that means my thursday night.

L

Yeah perfect yeah.

A

Okay, excellent: let's do it I'll, add that to the calendar and I'll see ya.

K

The chat part of maybe the area yeah we.

A

Want to get up the forum, like our.

B

Forum for osc is where we want to have a lot of the technical discussion. It's not up yet, but I'm going to try to get that up as.

A

Soon as we can, because we should.

J

I'm sorry shall I set up.

A

Not really, but if it helps you, you can, but I mean I'm on so many different.

J

B

Things that I'm not sure if I would use it, but I do want to commit to using the forum.

A

Which is not up yet.

D

Though, but it will be soon.

A

Sure we've got a discourse, you know discourse the forum.

B

A

B

Got that set up, we just gotta, make it live. We gotta.

A

Do a little work on that and get that up in live.

C

A

Okay, otherwise, I.

C

Mean I do wait, you said you're not.

A

On facebook, though, uh you quit.

C

I'm on facebook, the most recent.

K

Video that you had posted about the 3d printer houses in new york, there's a 3d printed house, the video that you put up. There's one company called icon printing that upgraded, which I saw maybe six months back or nearby icon printing. I don't know the same company but there's one more company that has already printed houses.

K

Larger like when we scale these.

F

B

Up we can get into that kind of scale too.

A

And and then, as.

B

I kind of implied in that article there it's kind of cheating, because walls are only 20 and those printers can't really do much more than walls.

A

You know what I mean like you can't do a lot of the other infrastructure using that kind of a printer. But if you use more of the kind of printers.

B

We're doing also for panelized construction.

A

I think that could be a game changer as well. The one you're talking about that's basically like concrete and walls.

K

A

That's not a big fraction of the house.

D

It's about 20, so it's when they say it's a 3d.

C

A

They're kind of.

C

A

They're not really being super.

C

A

They've 3d printed that but there's.

J

Much more to a house than just those walls that.

A

They 3d print, maybe.

J

They just mark it.

A

Again, but also.

F

Like you can you can do much more, but the ones that are there.

A

Right now, not there yet but yeah, it's the technology.

D

A

There's nothing wrong.

D

With the technology.

A

Okay, yeah yeah.

D

So I I would say like if you're.

A

uh Feel free to use.

D

Definitely the aussie workshops, facebook group, because that's that's open discussion of all this.

H

Stuff we're building here and workshops and stuff like that. So it's a good place.

A

Yeah, okay, excellent I'll post this meeting out there too.

I

That's pretty good. Okay, thanks a lot so we'll talk about.

K

I

Sorry I thought I.

A

K

Were closing the meeting I didn't know that you post meeting.

A

Sorry, if there's something else, please.

K

Continue, I'm more than happy to listen, sorry for uh suggesting that I'm trying to premature or hunting the landline. Sorry for that. No, I thought yeah there's something else we can continue, but I thought closing the call. That's why I said that sorry for that.

A

C

No problem, no problem.

A

K

I'll I'll get on to the other guys there, the major global I'll have a chat with them. Then I'll come back and post the documentation, and the next thing is.

K

A

No, I think, you're pretty.

C

Good you're, pretty far along, I.

D

Think you've got a lot of that, so yeah like as soon as we basically get all those parts sourced uh verify.

B

Everything yeah, you can buy them pretty quickly. I mean hopefully.

A

You know next few days, you've got the whole thing completed, possibly, and then you.

B

You source all the parts and you're building.

A

uh Maybe even well, it's gonna take you some time to probably get some of the parts.

B

But you can start on some parts.

A

And definitely.

C

You got to look into who's going to do the 3d printing for you like. Can you get those parts sourced by the same place that you're.

A

Talking about um yeah.

K

So, ideally, all the parts so I'll just check with them and the uniform is slightly expensive from the front market. So, let's let me just get started with you know you gave them the files for 3d printing already.

K

uh No, I just gave them the build up materials. They said they have most.

J

How long does it take to get it from them?

J

Well, they are half far away from me. Oh so you.

A

J

You actually would go there.

A

Physically yeah yeah, so that's.

J

C

Yeah, you can get started pretty quickly, yeah, if they're close by to you.

A

C

Have all those materials pretty soon then yeah, that's good.

A

We'll get going build the first first machine, you get the experience and then, after that.

B

Iterate and until you master.

G

E

Can sell these things and make them for others.

A

Yeah sure yeah.

K

And imagine they're gonna go for the I'm sorry, maybe there's a question offer offline, but uh we're gonna go through the steps of building start with the cad files. Or is there a step by.

F

C

I'm new to guide I'm sorry.

K

A

Yeah, um so it's we have the. Let me send you the link of what we have right.

A

A

So the main page, where everything is is this, but then in there you've got the.

B

Build instructions.

A

And they're not complete, but.

F

That's a good start.

I

So you can get.

D

A

E

All goes together.

A

E

A

The axis there's.

A

Yeah there's a.

E

Lot of different videos all over the place, so the basically the manual.

I

Is a good place to start, but we need to do an updated manual, because this this is still from the version.

A

I

Prior version, so there's some changes.

A

I

Most of it is correct.

A

E

C

That's that's one of the things to do. We gotta update the manual.

A

uh But the direct link to the manual is right. There you can see.

K

Bob you can see the control panel yeah box, quick attachment box legs, build instructions, the build instruction. The value is right at the bottom yeah. I see.

L

A

Yeah, that's what.

F

We have and there's also well, there's also.

A

Oh yeah, there's I'll give you another link, which is to the full uh in.

B

C

Genealogy, so we've got genealogy.

G

A

Where we show all the different versions.

A

We have a complete complete manual for let's say 18.

D

A

That, oh yeah, it's called 3d printer manual.

A

B

A

October 2018, that's super.

B

A

B

It's got the old, uh so what we did was right now. The axis.

A

Pieces are in one piece: here's where we had the axis pieces and two-piece clam.

B

Shells right now, we just have one piece before we have two pieces that come together for the axis material. But if you look at that last length, that's.

A

A super complete guide, but it's got the old axis design so.

K

If I build up as per the old version, I pick up one complete manual: is it possible to you know, take it apart and build for the latest version? Oh you know once you hit the second stone and once you build a version at a certain store. Obviously what I'm saying is the manual is for the earlier version and if I build it as per the earlier version and later you say, no, this part needs to go there. Can I take it apart and redo it or basically at.

A

The saturn storm once you build.

K

A

You do from welding, it's completely dis, disassemblable.

J

So you can do it's all bolt. I mean modular design for disassembly, so we're everywhere.

D

A

D

That can be taken.

A

A

Including the frame the frame is.

C

It snaps together, but you can actually take take it apart as well.

A

C

A useful thing would be yeah. You can't like, if you make a mistake, you just have to take it apart, but you seem like.

A

C

A

A

That's why you're going to learn it at a deep level.

E

G

E

A

And it would be great if you can do that would be to do the comprehensive.

B

A

Of the build, but.

B

That should come out.

A

Pretty easily, if you just put a camera.

J

On yourself, while you do the.

A

I mean you've done you've done a couple of things like that already, where you've done it.

D

You said you were scared to do.

A

The erector set models.

D

But you did it and it's great that's exactly what we need.

A

And then, if you have a good camera.

D

E

Then it's a passive process. You don't need to really work at it.

A

E

Just added the video at the end and have a.

A

Complete build video yeah.

K

Yeah, a few good cameras. What about that as well.

A

Yeah yeah: that's a good investment.

C

Because if we're teaching and building the community.

D

The communication part is the biggest like how we document and.

A

And have decent quality materials yeah.

K

What I'll do is I'll pick up? One comprehensive manual build it once and basically, once I get it right, then you know the manual is outdated for the next level. You can always take them apart. You know engine has said so not an.

A

Initiative, yeah, yeah, absolutely and and man we did.

D

We've done documentation so many times we just didn't. Do the super complete one for the last one, because we spent so much time in 2018. It took us like all summer.

A

To do that, and we just haven't gotten around to the very the very.

F

Very complete when we talk about the 2018, that's like.

A

Was it like 300 pages.

C

D

Something so it's really long.

A

D

We have every single detail.

A

In there so yeah.

C

A

We probably won't need that.

K

But yeah yeah, sorry so, which manual can I cut this manual for the earlier version.

C

A

Work, let me build this just.

C

For a reference.

A

Just use it for reference work on the current.

D

One but use the other one for reference, because it has insights on how you build like if there's a detail missing from the new one.

I

It will be an old one.

K

A

But the first thing.

K

I mean the real thing is.

A

Logically, you have to comprehend.

D

Okay, this is the frame. This is the axis. How like okay, you've got these axes in the gantry like, if you understand how the whole thing moves, you.

E

Have to understand that it moves.

A

E

It's a three-dimensional robot.

A

E

Can picture that and conceptualize that in your head.

A

E

D

Translates to the reality of the machine.

A

D

Have to understand kind of get the feeling for okay what's happening here, what's moving, what's not.

A

E

Think about it, a lot of the preparation for a build is just really.

A

E

The logic of the machine.

B

Itself that way, when you do the build steps, you'll be like oh yeah,.

L

B

Of course, of course, that's obvious.

A

As opposed to oh, what did I do next you'd be more.

D

C

This is obvious.

A

You know if you, if you can conceptualize what the build entails.

D

And that's that's internal work. That's kind of thing! You you're doing your imagination.

A

E

You said you work well with diagrams: do you think you're good at kind of imagining mechanisms or not.

A

K

I'll have to check them out. If there's you know taking putting things together, if it is imagining things imagining mechanisms, as you said, maybe I'll have a thing through it never done that before so there's going to be a discovery, yeah.

A

D

Definitely, by doing it with your hands, you'll get the concept, and then, after that, you'll be like oh yeah of.

A

B

Out there really.

A

B

A

B

That would be like a really important thing, because if we're going to start a business.

A

Doing this right, we need to document a really.

C

Good user experience.

A

C

Building it, I think, right now, people are struggling to build it.

A

C

Think we, if we make that much easier, that'll, be good and then we can do.

A

C

B

Stuff we can do for documenting, like.

A

There's augmented.

B
