A

Yeah I've looked into that and I came to. The conclusion of you are a RT would be probably the easiest one to take, and now.

B

I look into your.

A

Presentation, I thought the same thing as you called up to print, and this is simply marvelous exactly what what we're searching for p.m. so I can multiply it. Eddie with these is. This is capable of monitoring everything via by Ethernet like I propelled services, harlot alliances exactly what what they did and for Sara attempt on using it on a successful attempt on using I, don't know on several principles at once. You.

B

A

Should be Pablo as well, yeah I found two links I'll just written to you. I can write it to you right now or I'll write them into the work lock today.

A

Okay, about that um I love, this, the software seems kind of easy actually was when we're using this so packets of much more for Marlin. So it's comfortable for our printer yeah.

B

A

Software and I was thinking only about because the set it should be scalable yeah.

C

A

Maximum to up to 100 and I thought how the hell should we get 100 different cables lying around the chaos we just use USB, but you're a are GPU would probably be the resolution yet yeah.

B

A

These are the different different things I thought about what what I originally thought about the string has blackened, so we can put additionally some things like measure of how much filament excuse you.

B

A

Many other things and Korea's others, but interesting enough, like an API, so we could easily write our own on scripts to do a specific task, a task like when you're, for example, and fully automating this and you're trying to make this red lab yeah, yeah, it's or just it would be kind of interesting as a tool to give a bunch of stll them here.

B

A

Fabricated and maybe we could write a kind of script that would do that and give back and kind of PS how much is used and so on and so forth, without any kind of interaction from a real person, but just the computer that shuttered further to this. To the true mind, I think this would be a kind of a good.

A

This was a fifth without need to predict pretty well yeah yeah yeah.

B

A

Agree, that's my form. The last thing, maybe only a simile out of Fatima and I love project called get it here. Service, repetier, I, don't know yeah.

C

A

This there is a paid version, but a profit, but it has also a bit older discovers the newer version. Please I, don't know what how all this old version is, but the Muir has her default data for most printers rest of it is pretty similar to octoprint. So maybe, if our two printers making some weird things should be looking to, could be an alternative yeah.

B

A

A

B

A

B

No from have you looked any at the Marlin firmware, which apparently supports multiple printers and many mail is scalable. Have you looked at that link.

A

Looked like like how it's called to use, however, not only the option, trade, but also the other two projects as far as possibility to load up to be a speaker- and my gosh has octopus has has so I would, even if we're not using the Bible to cement the Marlin interface are just more or less copy from the from the repository in any case, yeah exactly exactly have a special kind of model, but I don't think so. You know.

B

Now we're just.

B

Just pretty much the original one.

A

Okay, yeah I think that's been a problem yeah.

A

Maybe there are some kind of reform of the cells you have to give you conflict data, but I haven't looked into the monthly camp and the printed on the octo print, but normally you have to give it a config file and it would be quite interesting what kind of data you have to fill in this config yeah.

B

A

I find- or maybe you can just send me well with email, so I can think like length and.

B

A

I can make it a call, I can send you the config module and, uh and you can you tell me what what kind of values yeah right.

B

Yeah one of the biggest things would be to get you some experience on 3d printers and the best the question is: maybe, if you can, can you look into well look at so I'm going to Google Stuttgart makerspaces.

B

Because they have space like, for example, makerspace next up.

A

Even that's not something big like I said: I know a few people of the scene by the but I've never been even to myself. Yeah.

B

I mean the one thing that I'm thinking it would be very useful, for you is to get familiarity with 3d printers, so you'd want to find either the Fab Lab or the makerspace and just start using one, because then you'll understand like all this stuff about configuration and everything else. But of course the the best thing would be to I mean if you could build one of ours.

B

That would be very good, but.

A

But I've been actually uh I'm, just at least on Calvi album, just bounce yeah.

C

I know it's not that.

A

Much but it's just depending upon what, with your average month at the moment, it'd be impossible right, yeah.

B

Yeah, so finding yet so I think the priority should be to find let's the makerspace is stupid.

B

A

Music, something here usually pretty big, actually I- think I, miss mom and my university as far as I know that they want something.

B

At your university, sorry, what's your university again.

A

Got universities, that's our own special name. Actually, it's just been University.

B

Makerspaces they have a makerspace there. Hackerspace.

A

Think good I think it was something like I said: I know a few people for them. I'm gonna come with them, so.

A

Excited introduce you just I've, never used to bother, but I've often found myself about those who have seen many videos like like the hard work and stuff so as I'm not I'm, not entirely new to it. However, I don't know what what can filament is best for water and stuff, like that, just.

B

A

B

So here's one, for example, yeah Shaq Shaq space got de stood guard shaffer space, for example. Space is open.

A

That's perfect: yeah yeah. You.

B

Really want to try to see if you can find yourself for that, but in the meantime you can research just keep researching the route to doing this, but eventually you would have to I mean one side is documenting how everything is done documenting the whole system. The implementations are basically start writing directions of how like, if you give me that those directions- okay, get a Raspberry Pi and make these connections and so forth. If you can design that very carefully, then I can do it here. So that's that's one way to do it.

B

If you can simply start producing those details and the see this is how I'm thinking about it and I want to see. If this logic makes Speight makes sense. So say you want to scale up to ten twenty thirty. Forty, fifty printers, you know you've got some operation going and you've got real good production, then running. All those wires is pretty tricky. I mean it's just too much infrastructure, so the best idea would be just send the data over through through some form of wireless and therefore you avoid all the wires and I know that.

B

There's the challenge that for streaming, you don't want to do like a long streaming wireless print, because that's that can get interrupted easily and how do you control if.

A

You can surf on the structure, but thank you.

B

A

Right, especially when you think about the class per se, are not that big. So it's not really a pain to send early in advance for exactly.

B

A

Or two or maybe three so I agree to put them on because.

B

Yeah yeah, so if we can specify that as our requirement and I don't know what octopi does, but the way I saw that for one I, don't think they do it like that, I think they typically use a wired connection and the way that.

A

It doesn't actually matter they they'll, take it out of the bath; they they they put out there. So as long as you've got something in your theater for em playing in you look at is MX and you can more or less I think it's not problem evil to make it with Bluetooth and stuff, because, as long as it is in your death directory, it will get it out and try it as long as it's a serial port. It will try to to make connection yeah, okay,.

B

A

I, don't think, especially with this lot. It's the riot, the r8 you.

B

Ever see you what.

A

Hey I, don't think it's any problem that I don't think anything the closets, this Wireless isn't in chakra /. The computer is Wireless because it's just something black in where otherwise there would be a table. Yeah.

B

A

No time no no way to distinguish system yeah.

B

A

It's not nothing different compared to making with a cable, so I, don't think there should be any problem. Okay,.

B

So if we can find a route word where we can do wirelessly, you send the file over and then save to SD card. That would be the preferred route. So what do we need to continue working on it? So so can you continue researching that that avenue of doing it and see what you can come up as.

A

Early as I actually think of this, this is all are already the solution of octopi, so.

B

A

May be some kind of obstacles, but look.

B

A

It works it's exactly what we're searching for so there's also a way of up life loading into an empty Cup. So.

B

Grass, before before.

A

Making it that would preview you can you can look up everything and it's just available by a Ethernet, so yeah.

B

A

Can be running everywhere without any problems. Okay,.

B

A

Api, we can also make it anyway and what.

B

About for conditions, where say there is no internet. How do we do that? This.

A

Has nothing to do with the interpret Ethernet? It's just your local network. As long as you want the same router as the rubber pipe doesn't matter. Okay,.

B

A

The only condition that wouldn't work is actually when you have no Ethernet cable left or your routers at totally falling apart and even then you could connect your router type to your old PC and get it to work, although this would be pretty complicated, actually and I'm, not right. You could also connect a desktop to the other PI and put in its own IP, so dokgo off, and it was also follow-up. So.

B

A

That way, it's just for convenience, it's normally for the local network, so for your house at nothing.

B

A

Accept you with ex, especially with them. You are explicitly wishing that. Okay, forwarding, okay.

B

So so you have a local network or Ethernet connection. Then how do you so say that controlling Raspberry Pi? How do we initially give it? The programs like so so say we generate the workflow would be actually that's. Let's document this so I'm in this I start this a separate document. So take a look at this. This one and so I just make the transfer the stuff from before. Let me share that make sure you can edit that yeah yeah yeah anyone can edit this one. So you.

A

B

Yeah go into that so so, let's start looking at wireless sent to SD card. Okay, so say the workflow workflow, so you generate typically with freecad, generate files with freecad. So.

B

And then can I use this like, for example, on this computer. So let's take a use use case I'm using this computer I just generated some some 3d print files, I'd like to send them to my print cluster, so can I just communicate open a connection to the Raspberry Pi.

A

So I looked upon it, it's heavy, heavily I'm development, it's finished, but it's getting better. So so I'm not quite sure what the point at moment is on a development, but as far as I see you can upload an STL file. I, don't know if this is PL or I, don't know three other than the dangerous file free travel worker FTL's work in every way. Cadell gets life down in this G formatter or computer.

B

A

It gets sent over ro.

C

A

And the bigot, and over and saved or streams Highland, don't think it shouldn't be a problem and.

B

A

I had too much time, let's sleep and maybe I can make an internal converter, so you can upload the free card and it gets from the server converted into SQL before get converted to G. So then, then we wouldn't have any kind of cognitive stress. Oh.

B

Wow that would be yeah that actually would be quite useful, because then we wouldn't have to keep a separate set of STL files. Yeah. That's.

A

That's like you look like maybe I, don't know whether this would work but I'm pretty sure patent can do such stuff, and this is already part. It probably would only be a kind of reeling of the works loaded. That's there already yeah.

B

A

I have to get to that yeah.

B

Yeah excellent, so so let's say we generate files with freecad. We can say optionally, later use native freecad.

B

Format for printing so open the connection to a Raspberry, Pi you're, sending this file to a Raspberry Pi, and then you have the option. Raspberry, raspberry pi can connect to say 12 printers so that let's look at the current case because I'm looking at about 10 to 12 printers right here, I'm actually in the process, making nine more I just did the frames. If you looked at, have you looked at the open source, ecology workshops, Facebook, page uh hosting I,.

A

Don't have any Facebook of this crazy guy. Oh you.

B

A

Absolutely to do a wiki web slow, so I fit into it, but.

B

You don't use um you, don't use Facebook, yeah, okay, that's good! It's a good idea! Yeah.

B

Yes, I put some I put some pictures, so it's actually I'm going to cut and paste this into the document just to show for your reference.

A

Excellent, you have them yeah. We all will need an extra transmit that will receive for every firing machine and we'll need an extra converter from usb-to-serial for every machine, and this also means we will need several USB hubs, because every single will need a news before and this will at least we can use report and actually I think this is the bottle Cabot, it's not not. As a raster pipes, no I think at some point the USB will break down. Theoretically they could make up to 125 mm but I.

A

Think as it is, you see people do less of people, though I think it will I guess if the bed was. It would get so slow that maybe oh just right now attempt right.

C

I, don't think.

A

It will be a problem and all that printer, however you're, looking in the way to a hundred or something like that, maybe with inefficient arms right. But what right.

B

But, but what if you're, just all you're doing with the Raspberry Pi is just sending the file over to the to the Arduino with wire yeah yeah yeah.

A

I know I know what you mean, but I'm not quite sure whether how many USB HAP's you can prick.

C

A

Each other, until until they they break down, so what should we said and use power? One filter so such things that take an additional table for the old power source and when you're using several of them, probably drastic I, will deliver enough energy. So, okay.

B

A

B

So you're talking about yeah yeah, so you're talking about like yeah you can. You can put that into the document like you can start new pages in this like, for example, have you used Google Docs app before.

A

For four years now so have that that's not a problem. Okay, it's just I, don't know how your structures so I thought I don't want to oh yeah.

B

No, no just don't worry about that. Just just keep start adding pages with different different things on the front page. What we want to do is actually we probably want to copy the front page duplicate that and just put an index on the front page so that okay, so I can just start the index. So we can. We can link on the first page. We can link to the different pages so simple index. That's all so. We keep track yeah.

B

A

All right, it's a bit laggy back here, yeah I'll! Do that probably those powered ones. We will need the confident receiver after that I I personally added the greatest job form you'll actually be not to set the printer up at least I hope to resolve the domaine job. I hope I can concentrate on putting in several printers, as it is not not specifically designed to for doing them, but you can observe processes at each other flow.

A

The kind of taking several devices from the thing and maybe I can write a strip that kind of identifies the serial part and take everything that looks like a printer and put it and started giving for it. It.

B

A

Be okay, awesome.

B

A

B

So let me ask you this: we talked you talked about. Let me ask you this question so use we are discussing the possibility of we're sending files to a raspberry pi and that raspberry pi is communicate, communicating wirelessly to all the different 3d printers which have their own Arduino, with an SD card with ramps and SD card. So in that case, what what is the position? The place of the USB hubs, though, because if we're going Wyatt.

A

I, do you need decibel? The problem is UI RTC, as you probably know, is no no Wi-Fi, and it's not blue tube or something like that. It it's more like a specific wave and will actually have to use a different way for each device. You.

B

Know otherwise.

A

It would be sent to every device and there's no way to do this. The information.

B

You have there's.

A

No car we have actually two will actually have fifty transmitter, a water supply every and as many receivers one for the printer and one with high each, and then there is what we need. Many many USB port for the bye as everyone goes. Oh, isn't want to look. Hellishly I can't imagine uh-huh.

B

A

B

How do we yeah? How do we do that? Because we know that the Raspberry Pi that has what the four four USB ports.

A

Like I said, we can use USB off I. Don't think this will be any problem Luke as long as we're not all writing it. We can kind of try, maybe I research, a server but yeah.

C

A

Can just drive and look at what point the information gets lost. Okay,.

B

Yeah, that sounds good, okay good. So so what are the next steps then? So do you have enough information to go on for now.

A

Have enough information I'll try to make an image for now, so you have just to write the image onto your Raspberry Pi. Then you can set up the stuff- and hopefully your just test it for now with one printer, okay and look at whether this one printer will will receive and deliver, but this works. I'll. Try you'll, give me some kind of feedback. Okay, I'll try to make a script out of it, so it can automatically detect all the printers it's connected and kind of integrated into the PI system. Okay,.

B

So, okay, that's good, so simple testing and but let's let's then therefore start with what we need here, because I actually don't have a Raspberry Pi here, I have a BeagleBone, but let's do Raspberry Pi. So, let's, let's look at how that system would look like?

B

Can you continue drawing in there to rot mer-pup mm-hmm, the.

A

Wrapper pie is offered to third generation.

A

Oh, oh I can all read it. I can't write it. That's that's why I just described I was kind of confused. Well, why all the buttons are missing. Oh.

B

Wait, you can't you can't edit it ready, I can't.

A

Edit, it yeah yeah, sorry edited there in Germans. Writing sorry! So.

B

A

Justice use because I done it so many times and I just couldn't side the battle so throw.

B

A

B

Can you edit and.

A

Not yet but I hope.

A

Not yet no I'll reload it lady.

C

A

Loading it the trick all tricks, oh yeah, so will I, don't know how your setup is so for one thing, this all in your red lab, more or less yeah.

B

A

I'll send a flood so yeah.

B

A

Kind of big fabric, or not big, but some kind of yeah.

B

Well, actually so there's the workshop so wherever, wherever the printers are I've got some of the house here, some of the workshop. But let's assume there's a computer there's a wireless connection. I have a wireless connection on this, so so there's a router somewhere so somewhere I'm running off a router for my internet.

A

Okay, that sounds perfect, we'll do that, make the pie position a bit more flexible, uh-huh.

B

So we got the Raspberry Pi and that's right there. We also have we have wireless, so you so the Raspberry Pi is going to have a hub or just first we do. We do just a single, no hub.

A

So so that the Raspberry Pi will actually only have an SD card in the index for the for the opera opera and it will get energy via micro, USB, cable. It won't require more because it has a Wi-Fi receiver built in, and this will probably deliver for our week for all our users, because web server is GCP. So this means I look this up, so normal get made every file that sent to the server and the checksum is 34. So even if it's wireless and therefore not everything, no that's true.

A

It will ask as often as necessary until the file gets through without a mistake.

A

So there's no problem with using wireless.

B

A

The photo Ethernet connection right.

B

So we say it has built in Wireless or built-in Ethernet.

A

Both I mean Wireless, but it's actually the same sonico, so I called both sorry.

A

I'm, a horrible Santa can put it drunk yeah.

B

So we've got SD card micro, USB for power and micro USB would come from where and just a wall plug just a.

A

Wall plug, it will need, maybe wonder, half a pair at least better to, but.

B

A

Work one but I I just will advise it because then it could shut down at some point and one okay. It needs too much power. Rossler pedra a free has actually a pretty high power consumption compared to the other ones, but for what a test is Wi-Fi and therefore we can shut off the internet for them. It's not that much of difference and for another, it's very, very powerful. Immensely.

B

A

To the other ones, it's about 50 times faster at first generation and among five times faster at the set as a second well.

B

A

We could think about using this for other tasks as well.

B

A

About four more left reflects on my running and it's never even with our wellness at their high of usage, they're, never processed, never to over 25 percent yeah.

B

What's the clock speed on its, was it like a gigahertz or.

A

I'm, not quite sure, I think one point four quad-core. Actually you.

B

A

Good for distributing that distributing help tasks, that's perfect observer. Actually, nine.

B

A

At the moment you can, you can put very imperative main tasks on difficult to make backups when, when and island stuff, if there are any other tasks you leave your computer on, for you could actually think about putting them on the PI yeah.

A

It's definitely powerful enough for everything, except for maybe something like antivirus or rendering videos you.

B

A

You want to be patrolling all night long, okay,.

B

So from on a Raspberry Pi, the connection to the 3d printer, so so then here is we got a 3d printer.

B

Would that be Wireless at this point, so we get the wireless or just can we at this point, do wireless for the 3d printer, so that means it would have ramps with wireless module.

A

So the 3d printer at the moment, I'm not sure what a problem pretty princess but at first I think those wireless Qi RTC's are just placed upon the original as far diet, I've seen them so we'll just play some upon them and the the other video will never notice. Something has changed, become.

B

A

The same piece like I said: the Raspberry Pi, on the other hand, will have the other half of this of the setup and will then collect it like that, like it have USB connection. Okay,.

B

A

Actually, all so.

B

Like this, what I drew up 3d printer has a ramps controller board. We add on the wireless connector and then add the SD card reader to the ramps, which is available exactly.

A

Maybe also the PI was it receivers here that I have done the stuff? Let's do this yeah.

B

No just a simple diagram: some telegrams.

A

B

I'll make a broken connection for wireless I.

A

Ever that's perfect. What what I meant is is the connection tutor to the product. That's a good idea as well. It should be I.

A

B

Copy paste, yeah.

C

B

To Wireless mm-hmm so.

A

And and so that this is kind of what oddest, why am I, not not.

B

A

B

Change it right there there. It is so all right all.

A

Right, okay, exactly that, that's what I meant, maybe maybe we should kind of put in the.

A

What's other one say a USB hub for the USB 2 wireless in some way, uh-huh part, you see hopper some point. So so it's clear. How does this getting your.

B

Iv to wireless alternate rivers.

A

B

So it's got built-in Ethernet and it's got a USB to a wireless hub or what's it called what's cameras.

A

We Chandler used to be out just like that or one second, you.

B

Can you paste the link to that yeah yeah.

A

I, just I just sent you what a little mean, something like it is Jeong tried, but I think um it's it's nothing. Nothing complex just come like this.

A

Just one one track in self-exile: that's that's entirely within it, like you, like alike, a Ethernet switch muffle USB and should be powered that otherwise may be the power trust elements it's suitable for things like keyboard and such strings, but Wireless will probably take actually pretty much of energy of the engine. When there are ten on warden going to get prettier Angie le uh-huh.

B

A

11 so I mean here I.

B

A

12 access, Wow.

A

So they they cost around two to ten dollars. I think you're also, probably also dollars to help.

B

Yeah, that's all okay, excellent, so I'll just put a little little picture in there.

A

C

C

A

A

Yeah, let's do.

B

A

Our on this document, you can see thing that would be used, is, if you use be a part of the of the half. So I am wait.

B

Let's see so, how let me see this thing, so that has a USB connection on one side and it has actually.

A

A micro USB, as seen from maybe we'll just in converter or will those will look up for one with a USB connection button. A kind of like this circuit is that will be correct. One okay,.

B

But let's see so so how are you getting then, from that USB hub USB to Wireless? What do you need from there to get to the is that have the wireless module built inside of it and got more USB ports on it? Is that what it does? Yes,.

A

That's all it's just a multiplexer I think from from.

B

A

Second, in itself, so there Jeff multiplexer.

B

A

B

So it'll be so it's four USB ports, plus wireless transmission,.

A

Nothing while it to suggest that the app then there there will be the this converter like I sent you. Maybe it was another port, but the circuit will be like this one yeah onto disk. There will be something like that.

A

Didn't that's! So that's one! Now it's pretty long, but but I actually don't know like I said bluetooth would be pretty complicated. Although you save a lot lot of cable actually itself. Maybe we could use you to, but it would be pretty pretty painful as you not sent to several printers at the same time as you have had to pair at disconnect for every new, oh yeah.

B

A

Would be I could strip that I think, but that would be pretty complex actually because you had to handle it out every time and somehow you had to say the web starter, that something has changed laughs or you have to refresh that also on all.

B

Right yeah: let's not worry about that dart, not yeah. Let's not do that yet. Mmm-Hmm.

A

No I see this tutorial, just kind of explains how you can connect your Arduino to your computer, like it had a cable with exactly this this.

A

B

Transmitter we need one wireless transmitter per device like we need multiple.

A

5F1 per device also on the pie, yes,.

B

Yes, so here we're taking the USB to Wireless multiplexer for four ports, and then we plug in four of these guys yeah.

A

B

Say let's say: we've got ya: let's represent that. So you've got a bunch of these coming off of this one.

A

Yes, exactly and on the other, and on the other side it just plug in the wireless you are I are Q. Module pictures can be found this tutorial side. There are multiple pictures of I see.

B

B

Usb to UART, first and after this one we need the wireless module plugged into the pins here. Yep, okay,.

A

And which you should also look out, we have to find a known signal for each printer FSS, so we shoot by by transmitters that can be adjusted, so we're not buying 20 of these, and there are the same same wave and right.

B

A

Root mass, so this should be definitely on this point. Yeah I, don't know whether those in the links habits but I've seen em seem that breaks is.

B

Yeah yeah, you.

A

Cannot ask you to share a little wavelength of those so.

B

There's a multiplexer there's a USB to UART converter.

A

And then there's the you arch to wirelessly.

B

And then, as you are to wireless, yet.

A

About the little obstacle or you can see how this would look on the pie, so there Derek cable, coming out of one end and getting to some people on the other end on the outside you're completing the community, cable, plug them. Uh-Huh.

B

Yeah yep pretty.

A

On the unload here.

B

A

The middle of the side, yeah.

B

Let me copy a picture that.

A

Would be it I think this would be there.

B

haha Okay, okay, so I'm going to copy that whole picture and that's a good picture shows it.

A

um To be to be a bit more more more precise about that, we should actually just to be technically correct, Wireless always from the Rooter from from router, and it's never from one computer to another. It's always going its way through the router. So it's more like this when I'm doing alright I.

A

Have no time for this.

A

Oh, oh yeah, exactly that's what favorite right.

B

So we've got router with internet wireless.

B

A

They like that that this would be kind of middle estimate as an expense or a woman like that. Maybe.

B

So the thing after USB.

C

To your can break oh yeah yeah.

B

No, that's good bye, that's good!

B

This is UART transmitter.

B

A

We say here just one second, why battery's about to die and I'm just failing out the second minute, yeah.

B

A

Okay in time, all right.

A

I can exactly double swell.

B

Well so it looks like we've got pretty much our diagram, let's see so what else we need so you've got the you AR T transmitted. So now, let's draw the other side. So now, what are we doing to receive that so we're going to have a.

B

Let's see from the Arduino for.

A

B

A

I know what you mean: that's a the submitter for 'allah Rader looks pretty much the same. Yeah.

B

A

It's just put in with a serial port normally goes. That's pretty much all so a look with a fine picture for.

C

A

And another thing why I chose you a a RT after after a local food to floss? It has it's better metaphor for our.

A

I can tell.

A

How to seven four four four Wednesday, the other way it has. It goes fella with the wireless UART them blue tube year.

B

A

Ten meters range range to.

C

A

This range and UART about hundred to five hundred, depending on what kind of antenna you're using so you can exit. Actually, you could place the router upon the outside of the of the effect factory and oh well,.

B

A

Wouldn't make a difference: 100.

B

To 500 meters yeah, that's.

A

That's what I see and actually you could make it even better with placing another element. So you just make.

A

Yes, okay, I'm, really, tired. Sorry, um it's just putting off the old antenna and putting another one on after on the warm. So there you can buy spare antennas that will travel probably kilometres. It's no.

B

A

That but probably that won't be necessary.

B

A

Yep, but here actually is one one: kilo meter uh wireless UART, transient module; yes, one, okay,.

B

You are brewing, commands that I don't.

A

Think this is necessary, but rather just saying this is probably more suitable than ten meters, which means your China fixed to the spot. On some of some.

B

Please send a link to that one to the one kilometer yeah.

A

It's just manual, so I am quite confident. It actually looks like that. The wrong with you we're using for diagram. So it's also this site Ron. It's all also for forward one.

B

Kill'em meter huh RF transceiver module that antenna. There would do one kilometer, I I.

A

Think so it's it's more more down, so it's not like Wi-Fi with its five-year her to the 433 ahead. First phase like radio a fast little I, think. That's reason why I I think that's retire, I'm, actually, no love into that that much just apply physics, I, don't know, but as I've seen, several people tested that they could at least say that it's several hundred meters so yeah.

B

That's really good I love I'm, going to paste, then just just for reference. So maybe there will be some applications later on that we do need that, but yeah one kilometer. That's amazing!.

A

Yeah, actually, for for for this, is kind of what it can send. It's actually very far.

A

Yeah, so this is actually a flag. The thing I found storage folders, exactly like it. I think this is the one, but I should feel confident picture suitable for the other side. However, like it, you can see already it's just the four pins on on one side on our.

B

A

Picture you can see it's just four pins, a five pin story. You.

B

A

Them- and you just fix them today, out really well were normally the serial port would be, and that's actually all oh well.

B

In an admired, you don't have to do any configure and or anything else, no no I.

A

Think so maybe I'm not quite sure, I think it's normally four parts of five and I think this one is it's probably an additional energy source, I'd say I'm, not quite sure, but I hope it is somewhere here. Mm-Hmm.

B

A

Very sure, there's nothing more configuration yeah I can I can promise your dentist of retinol several times. You.

B

A

I'm not exactly sure what.

A

B

What we're going to do is we're going to take one of those transmitters and we're going to put it on them. That's called a wireless add-on right. That's that.

A

B

And that's it, and now we can so we can represent this like this multiple from this multiplexer. We can essentially go to I'll just draw this without drawing this, but basically we can now control a bunch of these right. Yeah.

A

Yeah, exactly who.

B

Can they put this.

A

In some kind of cloud or something so it's maybe it's visible that there could be many of them. Something like that. Mm-Hmm.

A

Kind of half an executable, but it will do.

A

B

You can go like this another 3d printer, a.

A

B

Excellent, that's a good diagram here. So yeah, that's good! That's next! One yeah.

A

B

A

B

So now what I need to do so next page would be system diagram, BLM, build materials, so maybe we can start the next page on a build materials. So we've got. Let me just take a look at that here. So get the router with Internet. So that's that I already have I'm on the computer. I need a Raspberry Pi as d card micro power wall plug built in Ethernet. That's already has it.

B

The all the Raspberry Pi version three have built-in ethernet yeah.

A

Yep, they all have yeah, there's no burgerbob. We.

B

Can just say now.

A

Just one thing that that should become important like I said the USB wireless most lexer should just have an external power source, so we can scale this up as much as as the transmission speed will allow, which long so again, we should have done.

B

A

These wireless multiplexer there we are with its.

B

A

Metal mask reset in name names. We should put it all on the other.

B

Way, wait: let's see that's good. Let's do this.

A

Probably the wall plug should be then judge upon management is not not really important for diagram, but for your shopping list cut. So we.

B

A

B multiplexer half as an external power for something that's also powered by USB. So maybe you can buy a wall wall plug that has five or something like that because it a wall plug that has only one output. So it's most of time more expensive than than one that has several, and so you could put everything in their weight.

B

So one of those this multiplexer will have will have what one weight. How do you power it has an external another connection for power, yeah.

A

Exactly normally, the sprouts also like refer by wire, five volt, so over some kind of USB. On the other side, it's not micro, USB per default. Most it's some kind of a Ralph lock, you know, looks like the most little cable button for smaller and you just plug them in onto another USB port, and you could use the wall mount. For example, when it went through several USB outputs, because you already buy one and you when you, when you buy one, you can buy one with five flags, because this is not immensely more expensive.

A

It's actually warm out for one list here begins at six stars or something like that, and it goes up then, for five: it's only ten dollars. It's.

B

A

Of it would be quite useful to use one on one mount to to power everything, but actually you have to search this kind of multiplexer, probably something like active or or something like this or in work.

A

Okay, I'll just touch might as well see.

B

A

I'll find the.

A

Right name for it.

A

Yet a something like heart.

A

Just look calm, that's John, where's.

C

A

A

A

I'm not quite sure why they are so expensive, but.

A

I'll just give you a link of as an example, maybe find something cheaper. Just when I use my price, comparing our just get German German offer Center that won't help you so something like that.

A

That crinoline comes again why's, it always well, you get a picture, so it it. Has there also another clock some way.

A

This is actually with luxurious piece: okay,.

B

From some scientist.

A

Is actually is.

B

A

B

Is that the USB to Wireless multiplexer.

A

That's it just shut the USB multiplexer so that the yeah yeah.

B

A

That's the USB to Lyle exact same I mean.

B

You can really say wireless, a G, just a USB multiplexer right yeah.

A

Yeah, exactly it's just you yeah, let's come to read a poem yeah that probably looks better to just called use behalf of multiplexer I. Think harvester, the common, our compressor it but I.

A

Don't know I think you can be called off switch.

B

Okay, right, okay,.

A

C

B

All right, so that's pretty good. um Let's see, are you able to search for like us, Amazon where you are or it doesn't and.

A

I think it's possible, but it's not as easy as I thought, so maybe I.

B

A

Do that yeah? That's okay!.

B

A

Live in the future, okay.

B

So let's do slide to duplicate this slide and now get a detailed vom, then so sorry, what.

A

It cut off here, yeah.

B

Let's get a next step would be to work on a beyond, so maybe I can get. You can I get you to now do a list of all the specific parts part by part, so basically a list from from 1 to I. Guess like 15 parts or so here.

A

Yep your course, but just as kind of the problem about if.

B

You can do the German version like the specific ones then, so, basically, we need.

B

Ya, raspberry pi, yeah.

A

Oh I'll just use the John link for time and just something in the US. Yes,.

B

Yes, that's great, that's great, so we need everything from like after the wireless in the diagram, the router, with Internet everything after that I need the Raspberry Pi transmitters I have the only thing I have is the Arduino and ramps. Then the wireless ad on an SD card I still need that. So.

A

For the PI off what a 3d printer, 3d.

B

A

Both so the free trip it doesn't have an SD card. Okay, no.

B

It just tells so I'm going to color that in I'm going to color these ones in green. As far as what green, what.

A

What you already, where.

B

We already kind of.

A

B

So that's all I have everything else. We need Rudin. So there's one two, three, four: five: six: seven, eight nine ten just eleven pieces, so yeah. If you can complete that, maybe send that over to me and then I'll just get that and then we can continue. So if you can do that, we have time to do that today. So I can maybe order like tomorrow or something I.

A

Think I can do that today. Yeah probably will be lasting because it three doc- oh yeah,.

B

A

B

It's pretty late.

A

Yeah but yeah I think after that today, oh.

B

Yeah there's only 11 parts, 11 parts total, so that's good and then I can get that end. Data yeah I just put place whole day.

A

B

There's only a total of 11 parts, yeah.

A

It's all it's actually only ten, because it's ever passed sort of news. We have those coffee developed within the SPM in some way, either by buying a more remote chip and our wall clock or because it's in the box, when.

B

You say external powers, you're saying the wall plug for the Raspberry Pi and the USB hub power are going to be the same.

A

If I find the right links I'll try to manage that because it would be far more convenient as I'd say, yeah.

B

One must plug to.

A

B

Yes, it would be good, especially.

A

As we don't won't have only one USB half x, we will have maybe five or so yes.

B

The future for.

A

Maybe one big wall plug for several USB USB doesn't take that much of an LNG, so one flag should deliver axing yeah.

B

Yeah, so actually right now, maybe what I will do is probably yeah yeah just get one get the system, so maybe what I'll get is like a couple two or three of those wireless adapters so that we can start scaling up because one single hub, we can get two core printers. There will be good yep.

A

B

A

I'll just test and in some days I'll just test the image, but without my 3d printer of course, I can't quite see how comfortable it is machine. So you'll have to yeah yeah.

B

Yeah yeah excellent excellent, so this is really good. That's major progress, so yeah yeah.

A

I'll just need you then yeah.

C

A

Two actually.

B

So it looks pretty good here.

B

Simple system yeah yeah go.

A

Out so yeah all right, whatever one two, six more or less personal interest about the project in our scale, it is about the scarcity and, of course, about the about make the resource from scratch. As far as I could find. That's that's right. Actually, oh nothing and yes,.

B

A

Most of the part I could find or I could find a way how your machines put manufacture practically everything, but there are two major parts to relying upon without kind of special solution, all about driving a way and I just want to ask whether you have something in mind, and one thing would be the generators, the diesel generators or whatever so there and those are kind of complex things. Of course, they are not quite the scare this other parts, but is there some kind of idea how to produce them? Yeah.

B

Well, in the global village, construction said: there's the external combustion engine, which is a steam engine, but once we have the CNC machining infrastructure we can make them. We can make engines in the future, so yeah yeah, absolutely absolutely so I mean that's. People have been building engines for about a hundred or two hundred years now. So that's not it's not super difficult to do that.

A

B

Probably I know.

A

How they work and I know they have many parts and I come wide. Think of how to build them. Yeah.

B

A

But but maybe well that you find enough from us and yeah yeah.

B

A

The other thing which is may be a bit of a moral concern, is what what about micro processors, yeah.

B

Well, I think we can do on the scale once again. Technology gets miniaturized just like 3d printers and micro machining. Once you have fabrication capacity, you can build a facility to produce micro, micro controllers and semiconductors. If you got silicon, you got sand, you've got chips, so I mean that's how we look at so. The eventual goal is on a 20-year road map and that's have you seen a 20-year road map? Yes,.

A

I've seen it very ambitious yeah.

B

Right so you know we keep going technology by technology. We have photovoltaics that semiconductors already yeah I mean we will be able to do that. So that's that's the goal to show a showcase where you can do that, I mean when people did that initially I mean they did all in labs and then they scaled it up to two factories so think about spill. You've got the labs, but then now the factories convert from factories to micro factories. So you can do it in a much smaller scale and yeah yeah yeah.

A

But the factory processes have a such fashion, different approach on being produced. That's that's what I was thinking about I, don't know whether they have any open source initiative to to try this, because it's yeah.

B

A

This lot of sensitive materials, to kind of get rid of silicon and and get those those structures ends or something lightening election. Those tough machines are too big, so I don't know you.

B

A

Enough to do this, it's not I'm, not actually a proposal. Something I just want to ask whether there is you are kind of waiting for technology that that's going on on the scale or I know.

B

I mean look the individual machines that do those processes, they're small, it's just the fact that there's a whole string of them a whole facility of them, but each individual machine is it's not big. It's like a you know size of a room or size of a desktop. You know you can do that all on a smaller scale, so I don't see, I mean basically what you do is you and how does the technology happen today and then you can open source it so yeah. We aim to do that.

B

That's I mean that's just natural like in the future, as information becomes open that limits our there is no limits to that information can become open for everything. There are already open-source chip initiatives like actual chip design. Yes, but they're. Okay, yes, but there are no open source manufacturing projects that I know of yeah and.

A

That's where I think we come in, but yeah.

B

But definitely people are starting to design.

A

B

Open source chips and- and it's not a big big step to then say: okay, now we have open source machines that can do the chip fabrication as well, like refining, say, refining of silicon to solar grade silicon. Let's say that's I mean you can do that on a small scale. I mean not a problem, and that's so that's already semiconductors there. So yeah.

A

That's right: it's it's more more justice chemical process like like, like you're, a sorcerer I like if the photo sort of Justice layers and that stuff's cool I, don't know how public propagated that different people yeah.

B

A

That it will come with time, yeah.

B

Yeah, just like people like everyone's doing a 3d printer right now, you know that was impossible. You know a long time ago. That's so yeah everything is getting.

C

Our everything.

B

Is getting more accessible? It's true, technologically I, don't think I, don't think there are any limits to what can be done on a small scale. It's just technology is advancing, especially with like micro, micro manufacturing molecular manufacturing I mean in fact, uh so there's a one guy who's doing work on the open-source guy here, dr. Joshua Pierce he's got the open-source sustainability technology. Lab I mean he already just talking about open-source photovoltaics. You know things like that, so that that.

A

Would be awesome, yeah yeah then.

B

A

Kind of what what's missing in your architecture, the energy, the energy product production part, but not.

B

Really because well there's yeah I mean the roadmap, has TV production and and then at.

A

But but it's it's not absent that you feel kind of experimented with it, but but not with that rate of success. I've seen the idea of the nickel-iron battery but I, actually a Baretta chemistry, student and we've experimented a bit as well and just Provost said what was it now I think I, don't know what Tiggers thing wasn't even.

B

Thinking English.

C

B

A

B

A

Yeah actually I think think iron. What was out of the view of the professor was actually more efficient, but the file gives you some forth. Informations I can actually ask in them, but when you're kind of interested in that and when you have time for it, especially there's.

B

A there's a profession, it's knowledgeable about nickel-iron batteries,.

A

It's not about nickel-iron, but, but is that that this wouldn't be that effective as nickel, zinc and zinc is also pretty pretty level uh-huh.

B

I, don't know about all I know is that that Edison batteries they last for a lifetime. They quickly added.

A

To the basic product that, but not not the electrolyte, so you have to refill the electrolyte 30 years. Actually, so it's not that big of a deal, but you know yeah kind of it's true it it's pretty cheap and actually pretty expendable, but the thing is actually I'm, also pretty proficient and actually experimental throughout. We will just realize it's very, very it's not not that MGM simply pretty complicated bill that but I thought it meant. Maybe you have another plan about that or no.

B

A

B

A

B

Yeah save it for another time: let's get the print cluster going right now, yeah step.

A

By step, one thing at.

B

A time okay! Well this this looks really good as far as the as far as the print cluster work, we've got a good diagram, so we'll get the parts and we'll test it. If we can I mean we can do this pretty soon, so maybe next week by next week, I could you know order the part I.

A

Hope I can deliver you the image for your testing right.

B

A

Week I think I can do that excellent.

B

Excellent uh yeah.

A

B

Well, that's right.

A

B

Yeah, this is really good major progress, so we'll do this and yeah. So, thank you so we'll talk then again, the next next meeting. Maybe you can next meeting. Maybe you can report as far as what you have found out so far, we can have you, like everyone updates, yeah.

A

I am kind of make I can I can shout the Cybermen can't explain it. Okay,.

B

A

What I'll do now is simply the program. I can also show the program, but that's kind of a difficult question should I leave you? What what better is it better to leave you with a image that kind of rudimentary with a good documentation or a good image, with a poor documentation? What well.

B

Good documentation would be better because we're we want to replicate it, so the key for you would be to document like I put some notes on the documentation standards there, but make it such that a novice can pretty much replicate them, because it's carefully documented so so documentation standards make it a make it transparent for beginners. So it's it's easy enough and make it for Ubuntu right, yeah.

A

B

And then, once we have this software, then we can include that in the OSC Linux distribution, once we once we get this whole print cluster worked out. We can put that as our standard I.

A

Actually tried to show that this was a good idea, because it would just be an image, so it's pretty big without any use as long as you're abusing until it would be 300 megabytes and it wouldn't be a program. It would just kind of played onto your sd card put a link into it. So you can just be.

B

A

Something like that I could put some kind of scripting that would pull it out of the UC repository or something like that. That sounds to me more reasonable, okay, but but we'll look into that.

A

B

Yeah excellent, so I think you have enough to go on until next week and then yeah whatever you have yeah just keep me in the loop so that we can report on it to the group meeting next Tuesday all right. Do that all right Christian or thank you. Thank you very much and we'll continue going.

B

Okay, take care, bye, bye,.
