A

Well, okay, good day, people are recording, so this is the first meeting for 2017 2018 2017 is gone so thanks for showing up and it's an update too. As far as what we're doing, let's change the light, maybe does that any better? No that's I'm in the dungeon.

A

Okay, this is the micro house to that. I meant here's, here's a brick wall, you look at it, brick. Walls, okay, welcome everybody. So let's give the year started thanks for showing up and first we have an agenda. So please everybody take a look at that pasting that, in this is being recorded so that anyone who misses that can view this afterwards.

A

So a little bit of review from last year, all together first thing is that last year was a total of six thousand three hundred thirty three hours. So that's what the graph actually sums up to the graph that we keep track track of total is six thousand all over how much value that is that that's a lot of value! You value it at minimal ten, ten dollars an hour, so it's like sixty three thousand dollars worth of contributions. Of course we want this to grow.

A

We want to scale our efforts, as always so in a meeting I'd like to just go over where we are right now and have anyone else, who's doing work right now, I know we kind of took a long break for the winter holiday.

A

I'd like people to pipe in on where we are and I'd like to start with progress reports of what what I've been doing lately I'd, also like to ask for a note-taker. So do we have a note-taker available.

A

I'd like to call out for a note-taker can, can someone do that.

A

Abe Abe or Roberto was that Roberto.

A

A

Okay, go guard! Oh! Why don't you do that, even though you guys fight over that? But yeah? Please go ahead so page two! Let's! Let's do that so first thing on the agenda, so I'm gonna go through all the items, a through m on the agenda, progress reports, so first of all, I've been thinking about the project itself. I've been thinking about Linux a lot as far as how Linux works and one thing that I I'm working on right now.

A

So if you look at my log, I actually started writing a book that, where I basically dropped down all the knowledge that I know about the project in terms of how its organized, what we're working on, how we go about developing it to align everybody because I think that's actually missing quite a bit.

A

So a cohesive view of what all is going on kind of like a somewhat like a call to arms for everybody who's. A future developer that to me would be the main goal of the book.

A

You have to start with aligning everyone's effort, so so we're really pulling together and and I can say that I've been at it for a decade. You can say, as far as the actual global village construction set itself that word I started using that I think it was 2009.

A

2009 I forget it's around 2010 or so about six years since then. Just really developing working on that fully, but I think it's it's very important to do that. If you want to look at my log, you can take a look at that and it's it's at the state of rough-riding right now.

A

A lot of the different ideas, but I I want to go over pretty much the global village construction set like how its developed like what are the projects that we're working on how we can approach it strategically to go forward in the best way. So one of the main things regarding Linux how Linux works is one major lesson. If you study, Linux and I was also critique of the open source, is the financial feedback loops right?

A

So, while people talk about open source development, as all people are scratching their edge or whatever I mean that's, not what the Linux was I mean.

A

Linux is clearly an example where okay, so sale, Ennis developed the first you know said: hey I'm, gonna write me an operating system in 1991 people joined it, but the thing that was there is that it was a product and a real product that people can pretty soon get and get livelihoods from which, in its history, in that 20 year period, resulted in the first billion dollar company, Red Hat and, of course the overall impact of Linux is much greater. I would say it's about a trillion dollars right now.

A

If you look at all the software projects revolving around Linux that exists, so definitely there's a financial feedback loop that has to happen. Otherwise, why are people doing that can be just for fun? You know you have to end up at ok. Are you doing the further thing? I think what the the part that you can make a living from it, also one of the essential designs of Linux, the the freedom to sell the product and make a livelihood. That's it's it's a big thing.

A

It's a it's a critical aspect and when I think about that for open source, ecology, I think it's one thing that we can do better on and get many more people involved when we're transitioning to the livelihood part as a real outcome and making that that real.

A

If you look at the mission of open source ecology, it's to create the open source economy, it's really mass creation of Right Livelihood I've talked about this before you know, continue saying this, but I think the opportunity right now that we have, in our hand, is, is on a 3d printer on the on a brick press. Those are the house actually those three. If we take a look at those three I think those three are the biggest candidates that can result in a lot of economic activity happening that we can also collaborate on.

A

So what can we focus on for 2018 we're definitely working on a 3d printer? We are if we talk about that, there's the filament maker. Also, we started the Lyman film and extruder last year, and just now, I've been been continuing. The discussion with with Matt Rogi from the Thunderhead filament maker. So if someone who someone click on D & E, please take a screenshot of that and paste it into slides number 3 4 & 5. Someone can do that.

A

Take the links from D en F in the index on page 1, so the PV system, hydronic, stoven and thunder- had a filament extruder. If you can paste those into the document, that would be great, but the Thunderhead okay. So that's I, like it talking to Matthew or Matt from the project. He's got a good product. He's been working on it for many years like since I think 2012.

A

So we can pursue both the Thunderhead and the Lyman filament maker, both very good projects. The Thunderhead is very impressive: it's much more advanced than the Lyman, yet it builds on a lot of the same elements and there's a lot of, but the idea here is if someone is working on it in a very coherent way and they are, and they did decide to open source it to the point that I'd like to run a workshop on that later in a year.

A

Maybe mid year because their filament maker is fully open source and quite good so definite opportunity, but thinking about the the collaborative Enterprise on the 3d printer, that's you know. We've got right now: I'm, actually putting together a 12-inch bed, 3d printer for myself and also actually to ship out to a person from a former workshop, but the 3d printers there's a lot of promise. We've done the the circuit mill with it.

A

We can do something like a 3 watt, laser cutting head in which you can cut cardboard for models, so so the 3d printer can can be the core part of the little micro factory that we can actually start producing real things.

A

So, with a circuit mill with 3d printing and with the ability to cut things, you can create a lot of different products from from like replicas of the 3d printer, like kits for 3d printers aerial drones, robotic arms cameras, digital cameras, laptops, you know, think about making a 3d printed laptop case and other components of the shelf, but lots of different products there. That are possible with that.

A

If we want to do that, but I'm thinking that, as far as the collaborative enterprise there's a lot of elements that we can develop together in terms of like a marketing website, where think about it, how do how do people?

A

How can people make revenue from this I mean? There's a lot of different products around the 3d printer from selling kits to selling products to selling information products like all our stuff is free, but also we can charge for things like if it's a printed book, little swag pieces like stickers and other things giving some to the marketing aspect can produce something where we can.

A

We can all share that develop that collaboratively so that, for example, like you know, even think that the brick press like say you know you know Roberto, say you're you're in the middle of Chile somewhere there. How does a person start producing brick press as well I mean you can do what you can do like like? If you, you can, for example, create a website where you can actually be selling kits that you figured out how to get cut locally and you're a kit seller safer for Chile. You know like anywhere.

A

It requires work that the person who's running any kind of Enterprise learns and provides that value of the information and skills and know-how. So you can't just clone a website and call it and you're gonna get rich off it. No I mean it's something that you invest in and you learn a lot about it.

A

So you're you're, literally selling your information and digital economy, but at this as the economy switches from products to services to experiences like an experienced economy, which is a forthcoming thing so anyway, I'd like to you know, have you guys think about or have people think about? Whoever is listening to this about ways.

A

We can collaborate such that there's, a direct feedback like if you, if you work on a website, like templates like imagine, a 3d printer website where we're spawning not just one but a number of these businesses worldwide and I- think we can encourage people to slowly and surely to create better products. It starts, of course, with great open-source product design like when we finish up and then really really refine the 3d printer I think that's a great product gonna be selling kids.

A

Anyone could do that if you have a 3d printer, so a lot of different. Let's think about how we can leverage collaboration to make that happen in all kinds of ways, because I mean the 3d printing case for a lot of different products can be made. So so it's just a thought if you click on a three three watt. Laser thing.

A

Let's see I'm gonna share my screen here, so you can. You can look at where I'm looking share screen yeah. You know three watt laser.

A

You can get this little laser for three Watson, because our three watts SiC, like $60 and this thing works. We can add that 2d 3d. That would be a great thing. So this is an example of that on my screen here: cutting up to six millimeter plywood a little little plywood stuff, but I just thought of that as okay, that technology exists and our heads for 4d 3d are interchangeable.

A

We have quick-connect magnets on the head, so that would be actually a great product I'd like to see if we can develop that it's I think it's a great great product that we can add to our d 3d infrastructure, just like the the circuit mill. So that's the product of a three laser cut with this tiny, three watt laser so think about how that relates to us.

A

If, if you, for example, like say, say we designed the brick press which is made of flat steel, you can cut out a complete model of the brick press using flat modelling or like the house model for for open building Institute, which we promise as a reward for Kickstarter can make kits for that. But basically, if you can cut out of two-dimensional plywood, you can actually prototype scale models of the real big machines, including tractors, and we can cut out tubing.

A

You can take cardboard and Bend Bend paper into tubing to make tubes and you can literally build the entire. Like like say we did.

A

We did the micro tractor build this year. Someone remotely could be prototyping that completely using a laser cutter like that. So that's I think that's very, very useful. I think we can really beef up our prototyping infrastructure, with an access to a very small laser cutter like that. That really won't break the bank that laser head itself is $60 on eBay. So that's that's just one thing: okay, next I want to talk about the micro factory, hero X, so I've been thinking about a lot.

A

I have not taken any action on that hero X as the crowdfunded crowd, design, challenge and I will put on the work on the cordless drill or power tool. Construction set. So a cordless drill. That's completely 3d printed, so the hero X would be a big prize for developing a commercial-grade small tool which would have also interchangeable heads. So you can convert it to other things like jig saws or you know, drills band saws like a lot. A lot of different cordless tools so be basically a handle.

A

A tool head, a motor, a battery pack think about a tiny, cordless, chainsaw. Even those exist, so ya haven't taken any action on that outside of lots of thinking about it. But I want to post that up, raise money for an award and that's also another way to add a financial feedback loop here. You guys are not going to be most qualified to compete for that. Actually, so so that competitions gonna be open to everyone and the requirements are gonna, be hardcore.

A

Open-Source like, for example, you're gonna, have to use free CAD for the modeling of it, because otherwise no one can communicate with your CAD, so it has to be CAD free cat compatible and using, like all 100% open-source Libre tool chains for the for that. Okay. So next time here in my line here is a CB press marketing website, so both for the 3d printer and for the CB press and then for the the house which we'll talk about later I mean on the house. We're.

A

If you look at the pv system and a hydronic stove, you can paste those screenshots of those those have been finished, but marketing websites collaborative websites where we have like say d3d, open source, ecology, org or like say CB, open, source, ecology, org, and then you can clone those websites. So what we want to do is design all those templates so that you can actually start marketing stuff, basically I, think about marketing collaboratively.

A

So everyone's involved and I know that may not make a lot of sense to you people, but as we flesh this out, I think there is a huge case for collaborative market development. Just like Linux I mean how do you relate that to Linux and Linux? It's kind of much easier like in Linux you're, a software programmer you get hired by somebody you make code for somebody. I would make the case that the marketing aspect of that is not like the financial feedback. Loop is much more easy for us for physical Hardware.

A

We can take a very deliberate step in helping get people set up for that, so that includes both the hardware equipment. The micro factory aspect, the 3d printer laser cutter, the other tools that we make available readily and also this software back at backends that make that all feasible. So the kind of stuff like Lex is working on and Lex. Maybe I can hear more stuff about what your thoughts on the marketing side are as well, but that's that's a no works too, so definitely and the basically.

A

What we're saying here is that we're making it different from everyone else that we're also revealing the source code of the websites of all the marketing stuff, just radically distributive enterprise, google, it distributive enterprises all right. So that's all really stand close to ok, PV system. Ok, I was hoping somebody would paste that in the PV system, there's a video I just wanted to paste it. The idea here is to paste this in a working doc.

A

So that when people see this, they can kind of see the scope and breadth of what obviously is working on instead of looking everywhere, so because these are public documents. The meeting agendas we'd like to pretty much paste like whatever whatever is happening, but if you want to take a look at that, that's basically walk through the PV system. What I'm seeing there right right there is, for example, that's the PV power to fridge, which uses 8 watts on average.

A

You can find out how we did that super efficient and more about the PV system and then so that video has been published. The hydronic stove is complete and working. Look at that baby. It's it's really nice from the very build to heat right now, using a fully open source system. So that's all good and we actually installed a pellet stove backup. Just one of those pellet stove appliances.

A

We are gonna, put a pellet burner head onto the stove itself, but we did a pellet stove back up in the meantime, partly because it was the most freezing weather we've had in a very long time here. So it was actually when a stove burns out it they've got cold like at night I mean that's the thing, but anyway we're gonna open source. The pellet burner, which is we've, got a partial prototype built already, which you can take a look at more of that. Okay. So that's that's kind of all.

A

My side I want to get into wall Thunderhead Thunderhead. Let's take a look at that. The picture of that is like that. That's that's supported to freecad in the working document there so that so, as you see it's a much more sophisticated system, it contains also a water bath for cooling. The filament, because yeah I mean it's find out more about. He can see the video see some of the videos online, but you can also go detect, portrayed click, the link there and all that documentation is there.

A

Matt is doing extensive documentation on the extruder right now. So, like all the you know, all the designs and here's a very nice diagram of it, software, it's all it's all there. So let's do that. So, in a background here, we've got a few people, building 3d printers as Armand Stephan, Roberto and Ahmed in Saudi Arabia, or any of you guys online. And do you want to just briefly report on where we are with that?

A

Because, because part of the effort was like some of the next critical items on the on the 3d printing is to do a better extruder I think that's a perhaps the number-one priority to get a better extruder that we make ourselves cuz. One they're kind of hard to some of them are a little different when you buy them off the shelf and it's a real pain to make it work in a in the workshop, where sometimes they're just slightly different, and they don't work or you have to. We have to modify parts and so forth.

A

So you want to do the our own 3d printer head. That's interchangeable, as I mentioned, with the laser little laser cutter, but we also want to print thicker filaments. So three millimeter film antenna nozzle like like 1.3 millimeter nozzles for much faster printing of much larger things like like one discussion, I'm in right now. As another open source project on a windmill where we can 3d print the blades, that would be really good for that we need to have a larger printer and fast printing, because otherwise, with a small nozzle prints take forever.

A

But let's, let's talk about that? Any reports on that Roberto. Can you fill us in where you're at.

A

Yeah, so the question for you would be regarding prototyping the actual we can borrow the the Prusa i3 extruder that design the latest design that I have adapt that for our printer as a step, can you begin working on that or like? What's? Are there holdups or tell me a little more.

B

A

A

Okay? Yes, so so the next steps there I mean, if you can, if we can do that, have you looked at downloading the actual design from the Prusa i3 site.

A

B

A

Yep we do want to do that, so so, right now, I think the the way to proceed on that. Yet to do exactly that, adapt it just modify it a little bit so that we can put it on to our current current printer.

A

Do you have a very low case, so so one thing that would be really good. Can you do a like update the existing CAD that we have to reflect exactly what you have on your your 3d point, because I don't think we updated the CAD of the old 8 inch version, 3d printers and you have the third you have the 13 inch frame. Is that correct.

A

Do you remember yeah cuz, because I know that we made so many different versions that the actual like what we want to do is have a complete version of that of exactly that which you have, because that's you know, that's one. You can call it one fork or one version of it. We need like the exact model of that.

A

So the good thing to do would be to model that exactly and then make your modification on the printhead like how you're actually gonna attach that to that, can you think you could do that to drop the the full CAD and the the new printhead.

A

Okay, yes, so let's, let's get going on that and basically, as far as the schedule for this year, like I, want to as far as the workshops that I run, I want to do the 12-inch version, but I do want to do the our own fulfillment extruder head, so this would be relevant for that I am thinking, probably like April or so probably schedule.

A

The first workshop at that time, because yeah yeah I just kind of take some time to regroup reorganize for this year make sure the design is perfect and probably do the the website well. I mean continue working on a website for the 3d printer and generate different aspects of that, like like the. How do you run a workshop with that 3d printer? So so we have to do some finishing work like the product. It's not like a hundred percent.

A

It's like a few updates and and modifications that we wanted to make it better, namely like the better printhead and some of the refinements to optimize the print bed area and stuff like that.

A

So from your model, for example, Roberto, you should see that the exact you have an 8 by 8 inch bed but I, don't think you're getting the full 8 by 8 inches so so to modify, make modifications so that we can extend the actual working working area like make it as perfect as possible for the versions that we have to work with, because little improvements can be made like increasing the bed size and so forth.

A

So yeah, if you could cut it up and and basically can you basically like after you take a look at the filament extruder like? Are you in a position where you can actually start modifying it, and you do you? Have everything I mean everything that you need to do that or do you have any questions.

B

A

I'd say: that's, that's an easy way to do it, since that we've got the magnetic head that can accept whatever kind of a head that we put on it. I think design is for that first I mean I. Think that's a good thing like, especially if we do like say we want to do the laser head on it. I think that that works. Well. That would work well for quick exchange, so I think I think we can do that. I know that people like in practice.

A

We found that the magnets are kind of painful to work with, because they're so strong and intend to jump out. It's not so easy to attach them, but we're gonna have to make it work, and you know do that reliably, because I think the magnetic mount is pretty good for the head, including the idea that the head can break off the machine if you have an accident of some sort. So it's good for safety as well, but yeah I would say, use the existing system that we have right now.

A

So take the X like the carriage part with all its magnet holes and then do an interface piece for that, not the holder for the extruder. But then this new extruder is going to attach directly without that holder bracket, because now that we use the holder bracket because there's no way to otherwise connect the the stepper motor and the extruder motor. But if we design the Prusa style extruder Bruce i3, then we can make it fit directly on our carriage. So yeah modify the the Prusa to make that happen.

A

I think that's straightforward! Do we have Stephen on a call.

A

Stephen no Stephen today.

A

Okay, let's move on, do we have German Pegman so how you say no.

A

Okay, no come on. Okay, um Lex are you on? Can you fill us in on dev, workbench and other stuff you're working on and any comments? You have.

A

Wait was Lex, nada looks like Lex is not.

A

Okay, nope, no Lex, okay, hey Bob; any thoughts on on the tract or anything.

C

Can you hear me okay, yep, yeah, Lex I think earlier in the said he was gonna be running late.

C

Slack Channel, he says home, yeah I was looking over, see tractor and the power keep stuff and I think I got. This. Just was gonna organize some stuff on the wiki and change of things related to the power cubes I think I got, but just a dumb before on the power cube for the new one, which I think is seven in 1711.

A

Was what it was name.

C

Large tractor kind of separated, the Bursar's, does I think I still need to kind of clean up some of the libraries on the wiki. Maybe on that make sure you get all the different soap on that plus I. Think I'm, not sure we don't have I was gonna, make some other documents, because I think there may be. Let's see, there's different versions for the 1710 power cube. There's, let's see, there's a bomb and then there's like the micro track. The spreadsheet and I think there's differences between those and I'm, not sure I.

C

Think some of that was just related to the spreadsheet in what how many but I wanted to I guess need to verify what sort of parts.

C

A

C

If the pumps and everything.

C

Yeah, unless it's pretty sent no resume to the old ones, but.

A

Yeah, okay, also, let's see which of those tasks we want to take a look. We won't take a look at your log just to see a little bit more about this, or do you want to share your screen or anything.

A

Let's go over that a little bit as far as the micro track status, so I've I've done a bit of digging with it quite a bit around the house. It's pretty awesome improvements there. There was a little bit of issue on curl for some reason like some. Sometimes the curl of the cylinder was getting messed up and I actually don't know the reason for that. That's when I rata lit up quite a bit it it would like not move the curl properly and I. Don't know what it is.

A

It's not developed and I got to troubleshoot that a little bit and, of course it's been freezing cold out here. So that's the tractors just sitting out there definitely one uh once it gets a little warmer just start using it again and documented and make it make it work and organize another workshop on it. We don't have one coming up for next year, yet, okay.

A

Let's see, are you trying to.

C

C

Right yeah, it.

A

C

A

So so I haven't touched it like right now, I'm playing with the 3d printers a little bit just to send one out, but next week, I'm looking at getting back to the torch table. That is absolutely right before we build anything like I want to make sure that so so, basically, like February, March, April I'll just be shaking down the torch table. It's it's such a critical machine for the whole system that I just want to get that perfected and then, when we design for the next build, we can use our own. That's the idea.

A

So so it's true, it might be quite useful, depending on where we are here to do some work on a torch table like for one. We don't really have like yeah I mean there's plenty of work on a torch table from CAD to everything else because like when we go to the power cubes and everything else, we'll we'll cut them out fool you with the CNC torch table and then make a better way for like as I was talking about the enterprise aspect, that if we have access to a low-cost torch table.

A

That's that's a huge case to start pushing it out to the world. As in okay, here's our plants, here's our torch table, get involved. You can actually start producing making a living out of that as a viable enterprise. So the torch table is a major items as a priority.

A

Yeah aybe, so we're looking at your screen here.

C

Yeah so I think this is the smaller power cube 1711 encountered, the axillary I've got like balls walking to buy uh-huh.

A

C

Yes, for that one, it's got the.

C

Smaller cooler, 12:40.

A

Okay, oh, that's it! That's cool! Okay, that's very nice! So for anyone who wants to open up that file.

A

Abe is that the file you're talking about I paste it in them?

A

That's the PC 17:11 auxilary, meaning one of the smaller power cubes there without the hydraulic reservoir. As when we're scaling one power cube, has the hydraulic reservoir, the remaining ones, don't need one, that's a great way to scale to lock it to higher power.

A

Let's see where did my.

A

A

Okay, yeah! No, that's that's looking pretty good. What what so? What remaining work has to be done so I'm, seeing the the cooler I mean I, think there's plumbing plumbing needs to be needs to happen. I mean there's all those all that detail. All that kind of detail, yeah I, would have to be filled. Then.

C

C

A

A

To ask you for this: let's, as we go into the new year kind, as we beefed up our wiki infrastructure, can you put in a development template the bridge once so? So what I'll show? Let's see if people want to take a look at there's a page on the wiki called development template and in it there's a shorter one and there's.

A

Where is it usage.

A

We will happen to there's: uh where did that? Go development template.

A

Okay, something vanished here, but there's a there's: a development template. That's got like 40 lines, I made another one that has about 20 lines in it. It's the abridged.

C

A

Yeah spreadsheet, what happened to that? Let me just look at that page because uh yeah definitely what we want to do like the general practice is whatever machine that we do as a new build. It really needs its own development template because there's just too many things like to track, and it's that's an easy way. It only takes a couple of minutes to put it so so make it make it a habit to put in a full development template, so we at least have great placeholders for that.

A

View history here let me just take a look at that real quick.

A

I am so confused here because I just downloaded the shorter template.

A

A

Oh wow, okay, go to this page. We got to fix that there's two pages with the development template, so the correct page with the development template. Is this one? So if you look on the go on the wiki, the page is just called template and it has a simple template which has got 20 lines in it, as opposed to the full template which has got about 40. So it's it's, basically the abridged version, but it contains all the key elements.

A

The full one is a little too overwhelming and this one is smaller, more manageable, but a B. If you wouldn't mind, please make a clone of that and embed it and make it make it editable to the world so that we can track all the things like, for example, 3d CAD should have the library parts in it.

A

So if we click on a 3d CAD like for example, if you have trouble okay, you don't know what the pump is well, we should have the library where the boem for the pump and the CAD they're both consistent, and we have that all in one place, so we're not switching between different versions and we don't know what, which is which that's, why I really recommend the the template as a place to organize all the assets for for one machine.

A

So if you wouldn't mind doing that, and if you wouldn't mind- please also set up, you know just to start filling out as much of this as we can and as we go forward when we get new people on a team, we can pretty much do the burn down. Lex has already created a burndown graph for the development template, so we can actually see that tracking over time. One thing with a 40 item template we just never really like filled one to a hundred percent. We you know we got you know like halfway.

A

There was just so much work right, but I think with this smaller one, the 20 item, one. We could do that as well as keep the the burndown graph, so we can see where each project is for our metrics.

A

Just like we're keeping tabs of all the hours of the development team, we want to do a burn down for every single project that we're doing and sometimes a burn down could be like when we quit that thing I mean we just call that a hundred percent burned down because it's an outdated version, so that could be another way to burn down to zero. If we said okay, we're not doing this anymore because it's we actually moved on to a new version because something changes or something like that.

A

But yeah do do that and then we'll start filling in all the different elements. I'd like to see it for every every machine. We try to be more diligent on a template itself. I know we put up a lot of. We have a bunch of templates on when I started, the d3d I call it sixteen twelve. So six sixteen inch frame and twelve inch bed so d3d. Sixteen twelve. If you look at that on the wiki I put that so, if you go to d3d sixteen twelve I put the template on there.

A

Cuz cuz, literally every new build, is considered a fork, so yeah, so I got d3d. Sixteen twelve, where I only got like a couple of items there like software data collection, but in general the requirements are very important. The calculations are very important. If you have those, then you can. You can compare very well like, for example, for the filament extruder like why. Why is the case for the larger Thunderhead filament maker?

A

Well, the calculations are gonna, show you or the data is gonna, show you that wow its throughput is so much greater than Lyman filament maker, and that makes it very feasible for for actual small scale, micro factory, work and stuff like that, but anyway use the development templates.

A

What else on a power cube abe's? So you know we touched on the parts we want to make sure we've got all the parts correct, because the better we make the documentation, the more people more. We can invite people to to collaborate like, for example, you can say hey you know: new person arrives on a team, we can tell them hey fix the pump, because it's not correct and they'll be able to trace. Okay. This is our Bill of Materials.

A

These are our other information and all that they can make calculations that it would say, hey. We don't want to use this pump. We want to use another pump because it's it's got more flow or something so yeah. The more we documented the better.

A

Oh, can you summarize the next steps on this on the power cube there? As far as the cat itself is, it goes.

A

Mounting you know the mounting system like, for example, details of the mounting of the of the.

C

A

Let me interrupt for a major point here. The cooler right now is not in front of the fan. The fan is the actual blue circular part. That's where the air is blown, so you got it in a place where there is no air motion. You see what I mean we. We wanted to put the cooler in front of the the air intake of the engine, which has a lot of blow of air so that we're cooling it automatically so you'd have to move it to the next side. Over on the front.

C

A

No, so what the air intake is is when you pull the pull cord on the on the engine. There's a fan mounted right to the rotor of the engine and that's on the front of the motor. So that's where we need it. That's.

C

Right in there sometime.

A

C

Connected directly.

A

To the engine shaft, so it's in line with the engine shaft, it's just the extension of the engine shaft, which is at.

C

The front yeah yeah.

A

No, no I was confused about that until somebody explained what they meant about the air intake as well. No, it's not in front of the filter, it's the actual fan on the motor itself, which is got a lot of flow yeah, yep yeah! So do that! That's that's a major the kind of detail that we want to get up to in this kind of CAD. That makes it really valuable is when you actually take the expanded matter. Metal mesh, draw the actual rubber mounts and exactly how they're gonna fit.

A

So it's completely technically correct, so that we know that we're not gonna get into issues like I know. We got into little issues about the cooler ending up, not fitting in the last build, because there was just not enough detail as far as the exact exact mounting, or maybe the engine was a little bit off, but I'll try to take a look at more of the dimensions verify that what we have here is our current engine model is pretty correct, because that's gonna be important going forward as that's the engine that we're we're using yeah.

A

C

Tracking all the parts in there position yeah.

C

As long as we get information to start with, which I think is off the shelf,.

C

But I know sometimes that's bump right up against the workshop, like there's a lot of time, so yeah better right.

A

Yeah no I mean I, think yeah. We got to do better than a lot of things. One thing is that if we can master the CAD that it's actually super accurate, then that will also open up more flexibility. In our part, I mean the goal is to keep streamlining this, to make it more more manageable, more efficient to to run an event like I mean that's the goal I mean still, you know we're struggling for every event to get everything just in time.

A

Of course, it's extreme manufacturing concept that you're doing it in such a short time, but I think we're getting there, especially if we have the torch table where we're actually cutting our parts. We can do that. We have much more flexibility on the order for the metal and stuff like that. So that's good.

A

C

Yeah static supply chain right.

C

A

Right, just yes supply chain is, that's the you know a big hard part of any hardware work, but yes, as we get better, we can refine that and the more things we can make in-house that easier. The supply chain is like when we start cutting out the all the metal parts, that's gonna be easier and so forth.

A

Do you wanna? Does he do you have any other other work that you have on CAD or.

C

The larger power cube this one here so yeah. This is the one with the tank I love to purchase. I guess I've got the coupon oxide again. That was their.

C

Tank everything.

D

C

C

Tank together, yeah.

C

Welding that was kind of hard I wonder what kind of mentioned.

C

Holders maybe like magnets and things the whole corners together to make it easier. Well,.

C

A

Yeah angles: yeah angle, magnets yep. We can do that yeah.

C

A

I mean just angles with magnets on them work. Well, that's one way or you can just rekt use regular welding magnets like off-the-shelf ones. So, okay, so I see that there is no power cube version, 1711, which please start that so in the document.

A

No, that's good! That's good, but wiki page called power, cube version version 7 all out 711. Yes, so I type that in.

C

Or I thought I've made one you.

A

A

Yeah, no I'm not seeing the power cube, aversion, 7/11, so yeah check on that and let's open up a new page put your CAD file, link them there and put the development template in there. So we we know, that's the official, placeholder and 17 point sorry 17 point: 11 did I say: 10 11 refers to November, which is when we started working on this. So that's good! That's a nomenclature! By the time we start working on the project yep or when it's built or when, when you start working on it, yeah.

C

A

Yeah now I know you've got the file on the wiki- let's, let's start a new page, to make it very modular. So we're not confusing this. We can always refer to the power cube version 1710, but all the assets relevant for 1711 should be ported over whether you're just copying and pasting or something else but yeah. Let's keep it separate, so we're not confusing version. That's one of the main things to keep track up in a in a project all right. Okay, let's move on here so I want to hear from.

A

Let's see, yeah I see Michelle you're on as well. Here.

A

Any report from yourself.

A

A

A

Okay, yeah! No, that's good! That's that's. Gonna, be very important like for the website, everything else and.

A

The report on, uh as far as the build event for Saudi Arabia, that is still not on a calendar, so unfortunately we don't have that yet. So not yet. As far as so you guys might have noticed. I also went to Costa Rica.

A

We are planning to currently like we got to organize all of that, but for for May there's a tentative date for a CB press build in Costa Rica, which would actually be a first international build, but the situation there looks good, there's a individual there who, who kind of is developing a developing land and developing a community down.

A

There he's been established down there, but he wants to build a brick press to build some structures with and- and we can do that and the question there would be to make sure we can get our hands on like six mig welders to make that happen in Costa Rica, but otherwise it's like with a digital design.

A

As long as we can get the CNC cut outs down there or possibly have to ship that we'd have to work that out somehow so there's a number of details that are not worked out yet, but if it's, if we can resolve all the issues, we'd like to do a build down in Costa Rica, which is where I got my first chance to some kitesurfing people, I recommended it's awesome stuff and if we establish so so, you know that's an initial contact with Costa Rica, but I also visited Belize and Scott Mader who's.

A

One of our longtime supporters he's bought a couple of our brick presses, he's interested in setting up o se South down there, and that's that's positive, so so, as we kind of go forward next year or two. If we build up our operations here that we maybe have some of the regular ongoing workshops, we definitely want to consider Belize as a potential site. I mean he's, got land down there like 60 acres, which is now blank, and we could develop that into a training facility or something like that and start producing equipment down there.

A

It was very interesting I. They have a Mennonite community down there, where they make their own equipment like, for example, they have this crazy-looking agricultural sprayer with huge metal wheels. I mean it looks like Mad Max kind of like our stuff exactly but yeah they're. They they have access to metal down there.

A

So, surprisingly, in Belize, which is not so industrial I mean they do have access to metal the the Mennonites down there do build their metal stuff, so we actually checked on getting metal like half-inch steel down there and it's quite accessible at the same price like in, like in America pretty much. But it was pretty amazing, it's kind of refreshing to see a bunch of the kind of the third-world style stuff and in Belize, but then there's the like the the Mennonites. They are very productive.

A

They run a lot of their agriculture, build their own equipment. It was kind of like feels like someone like Missouri, where there's Amish people and they have their communities where they kind of run their complete economies somewhat independent of the world around them was interesting to see, but the bottom line of that is that we can get steel down there if we wanted to so so that's interesting, yeah yeah, so that's kind of we don't have a schedule for the whole year. I am still trying to put one together by February.

A

First, as far as what workshops you want to run this year, I do want to run a bunch of 3d printers. There's two people that want to get brick presses this year, so planning on at least two brick press workshops and I want to give them so streamlined that they're, they're, very efficient and and we can start teaching people how to do them.

A

Currently, Katarina is working on a documentation for the CD go home. She got back to full-time of the documentation. Part we're looking at as soon as all that documentation is done. We're looking at setting up a training program for four builders, so the prerequisite is getting the full documentation on all the systems, including how to how to organize a build of a house. So there's a lot of work, documentation and training and all this kind of materials.

A

So not so, let's available work all over the place and we definitely want to have people start replicating this as a source of livelihood. So that's that, let's see now so if we go back to the agenda for today, I think that kind of wraps it up for what we have will continue working so so, basically Roberto the definite specific task and starting to look into the extruder upgrade getting to work on that. If, since the extruder is a small sub sub module, but it's also very important and we're starting that process from scratch.

A

Also, if you wouldn't mind, please create the development template from that using template. The short 20 item template from the template page under wiki and I'll just paste that.

A

Next to you, there template I, pasted it on the first page. Please use that to set up a template, because that's gonna be a nice development process where we pretty much after we have that done. I mean we're first of all, we're modifying it. We want to make sure that the sensor is working well, as we go to larger.

A

Just one more comment as we go to larger, build surfaces like right now, we're at the 12 inch but I want to I mean I just want to start enlarging that and just keep going bigger and bigger. So we can print larger things, like the say, the 3d printer printed wind turbine blades and things, but we're gonna have to master the kind of like the the flatness of the bed surface, including like we might have to go to a larger sensor.

A

I, don't know, hopefully that works, but I know that the sensor right now is very, very close to the PEI surface. Sometimes it fits so there it's a little tricky together. We might have to make use a larger one, which has a slightly larger space to the printer. This or something like that, but yeah, there's gonna, be just a little bit of development work and making sure that larger extruders are working and right now we're just going like for the Prusa they're they're, just working with a 1.75 millimeter threads.

A

So that's that's still very small, but we'll get to larger ones later so yeah continue on that I'm continuing on the book work and also want to start putting up the micro factory hero acts pretty soon working on a torch table as a high priority. So we can start cranking out metal parts ourselves and so forth. Okay, so that's I think that's about it any any other questions or comments here. Otherwise we can wrap up and call it a day. Okay now hold on a second Ruslan.

A

So Ruslan is a new developer here and we forgot to pump you in there work. Where are you you're not on our agenda? But Ruslan has been working on a pipe pipe fittings macro for freecad roost I. Can you pipe in a little bit? No pun intended.

A

Yeah, your latest just fill it fill in everybody. What you have done so people first of are aware of what you've been doing because I we they haven't, talked about your work.

D

D

Bitesize then, this battle will be some one of the possible Evo's yep.

A

D

Babies, love to spray. The beta 1 register spread data, which is Laos, which now can be stored in CSV files.

D

D

A

So yeah, basically the idea is that we're gonna be able to generate pipe elbows fittings, tees pipes, which is very important actually.

A

So if we wanna like when we're gonna get to the city, go home later this year for documentation the plumbing there, the bio digester system, that's all pipes and elbows and tees so so we're a basically model, have a quicker ability to model things that pipes so we're making essentially like a PI, almost a pipe workbench right now, it's in the form of a macro, but possibly we can have turn that into a workbench.

A

So when we when we want to have any kind of a pipe fitting of which there are many many sizes, we get that automatically without any sweat. Just like there's a bolt macro bolt, workbench, fasteners, workbench and free CAD.

A

This is gonna, be one for pipes which is gonna, be very useful for us to allow us to prototype much faster, Russa I'd like to ask you: do you think you can do a product demo for us next next meeting we can do a little screen shot and you can show us how you generate the pipe sections, a little walkthrough on that.

A

Where you would you be able to share your screen and demonstrate how you're generating so that yarn, okay, yeah, let's see how far you get so possibly we have a demo pipe pipe fittings demo from ruslan next next week and we want to wrap it up because I know you've been on it. We wanted to do that as small task, of course, like everything, it turned small tasks, turn into larger tasks.

A

So yeah, please wrap it up, so we can maybe move you on to some other more interesting tasks unless, unless you're you're really interested in continuing on this kind of thread, but yeah there's there's other things we can. We can do like, for example, applying these two to the actual design of a thing like the bio digester, and things like that. So we actually model modeling real, real, useful things.

A

D

A

Yeah we can readily apply that, to you know: I'm actually gonna be working on a bio digester here this week, so I can actually that's actually a fitting time to do that. No pun intended again all right yeah, so so continue on that place, and hopefully we will see a little demo next next week, so we can actually apply that to the digester, because we do want to get full CAD for all the subsystems of the CD go home, which then would enable person like Michel to also put that into into the WebGL.

A

So we have fully fully documented systems like that. Okay, that sounds great well. Thank you, everybody, so yeah. Let's continue, then, next week we'll continue making the road by walking here, 2:00 p.m. again I hope to see everyone there and we'll continue with our mission here. So thank you. Thank you. Everybody and see you next week.

A
