 computers keep changing the world but their power and safety is limited by their rigid design. The T2 tile project works for bigger and safer computing using living systems principles. Follow our progress here on T Tuesday Updates. Hey folks this is the last T Tuesday update of 2021 and 2021 quite a year. I've seen some old friends showing up in the YouTube live stream today. Thanks for coming. I've got a bunch of stuff and it's probably gonna take way too long so I'm gonna try to go really really fast. So the short story, the science fiction short story that I made by cutting down chapter 2 of what was going to be the unbelievably little three-volume epic that I can never possibly have enough time to write is done. It's just a hair under 4,500 words so it's pretty tight. It's pretty short. It moves right along. I've had one reader. Elena read it. The review is, you know, it's cute. I will take that, you know. Elena is not a big science fiction fan so all right. I talked last time about what to do about it, you know, send it to a magazine, send it to analog, fantasy and science fiction. I think I'm what I'm gonna do is I'm gonna send it to Asimov's magazine. Apparently you know they're doing about as well as any of these things. I mean I guess none of them are really all that big and they have relatively fast turnaround like if they have they haven't answered in a month and a half I get to ping them and I probably will have heard before then. So I'm thinking that's what's gonna happen. We'll see. Here's the final path that it went through you know right at the end of November big December there was the giant cut and this was the really battling it out get that last little bit figure out how to fit in the you know so I mean like living computation foundation mentioned in the story like that so anyway so that's that. In addition last time was talking about Ringo the generalized distributed ring oscillator idea for synchronizing plates. The goal was to get still to get L2 plates moving around they're still not moving today but I took a pretty important step towards it and so I wanted just to a super quick demo of that. Let's see that's this button yeah all right. So you know the problem is all right so we'll make a little here's a little L1 plate a little 3 by 3 thing we're gonna now blow it out to a L2 plate. All right now let's uh-oh what did I do? I don't know what I did. We'll find out. What I wanted was this. The labels. Okay maybe actually we'll go like that okay let's see if this is still alive. Yeah all right so it takes a little while to figure out what's going on here but the idea is in order to move an L2 plate you have to move the L1 plate so you know or the this is an L2 site this whole little thing which is made up a bunch of individual atoms and so forth so really what I needed was two ring oscillators going through each atom at once one ring oscillator that's controlling over the entire L2 plate from beginning to end and the other one which is going just within each little L2 site so the L2 site can tell have I finished moving my one little bump and so forth so this took a lot of refactoring this is the L2 whole plate cycling while each individual little L2 site is also cycling within it it looks kind of pretty all right so that's that all right and the main point I was supposed to end this year I was well I was supposed to build the grid I was supposed to finish the whole grid and that that hasn't happened but for just this time I was supposed to build at least one tile and in fact I think I built like five and I ran out of the little aluminum heat sinks that I was using on the thing so but I've got more of them coming in that I lucked out that they were available giving the whole supply chain business these days I think enough of them to probably finish however many tiles will be able to do 140 or something 150 I don't know if we'll get that far we'll see before we run out of something but I made a new flash image a new image to flash the discs with that has all the latest stuff in it and all caught up that was a huge pain in the ass I made a bunch of new tiles a few new tiles and what I wanted to do and this is scary part that is try to assemble a tile live right here and we'll see how it goes all right so that's this button are we okay we're actually sort of theoretical working here this is my little webcam which I don't know it tends to hunt on the focus so we'll just see how this all goes so step one we are going to be making tile G 247 right now because I already put it in the datasheet in the spreadsheet so we will mark it and the back of the circuit board has an express place right there where the information like that is supposed to go now of course people know that this is indefinite scalability violation right there because you know there's piles are all supposed to be like completely interchangeable grains of sand cheating for debugging purposes well I get what I pay for all right and so first step one is to put on the back cover the back cover which covers up all the little exposed solder points here if we're doing well has a little hole so that we can see it through I used to have to screw this down with screws but then the improved thing is we can just do it using the brass standoffs which we use we're going to use to attach the Beaglebone green later on now one thing that's just generally true here is that you know this is completely over assembled I mean I put in the the CPU the Beaglebone green the process unit and I screw it down and you know it's got 96 pins connecting it to the thing so there's really absolutely no way that the Beaglebone green is gonna vibrate lose or fall out of the off the pins and yet I screw it down anyway because you know the point not that works efficiently the point is it works at all so yeah just like the first VCR is absolutely built like a tank they didn't know any better that's what we're doing here we just belt and suspenders and then maybe another belt on another pair of suspenders so these are our brass standoffs we want to get them down snug but I have to avoid stripping the back plate because you know that's just going straight into PLA straight into plastic from the 3d printer so there we go okay now we need our Beaglebone here it is now I have already put this is the the heatsink which I have now run out of but more coming in I don't know how much it good really though I think it does a little bit of good the problem is is once these things were all packed together and put into the case they're pretty tight so now have I forgotten anything that goes before this I don't think so so let's go for it so you see here's the ethernet thing is gonna fit in that hole we gotta get them lined up right right of course one of the good things about having the bright standoffs is that we get the pins off line it won't be able to screw the pins so it's a little bit of a hint all right so now cheesehead Phillips I'm thrilled I haven't screwed up yet at least hopefully is it staying in focus we're lucky if so these brass standoffs actually do take part in grounding the Beaglebone green into the circuit board although there are plenty of other grounds through so it's not anything really critical so that's that next stop is to put on the display and here's the display it's already been selected and recorded in the spreadsheet you know every one of these Beaglebone greens I don't have it here comes with a little six inch USB you know micro B to A cable that I just have them piling up all over the place and every LCD panel comes a little stylus so I have them piling up all over the place not quite managing to do you know tip-to-tail construction of these tiles all right so the LCD goes on this other little header right here like that that's pretty good now I've got to go run get a cover I'll be back in one sec we can listen to the music how about that nuts are we still alive we've lost me well screw it but we can still see I'm just gonna go ahead and finish this so north and the other trick is the the K screws they screw into the feet and these the feet that were designed to connect into the whoops the frames that go in the back so we got four feet and they're gonna each one is gonna go into one of these and then the main case screws goes through it all the way and it was a huge pain in the butt to get them until we made this thing so this is gonna call it the speed frame because all you got to do is stick the feet into the frame so that and it's got a little hex it's essentially four wrenches in one that's a great sound one more step so yeah I don't know what it is but I've got some kind of static problem or something one of the things about being in a dry climate it's good for a lot of stuff but it's bad for static and it's like whenever I move USB the main USB camera on me seems to freeze up and I don't know why and the way I solve that is by not moving but that was not an option here today because I forgot the part and so these things I mean as if this is training so that we can all make T2 tiles one day in the future the way this worked out the screws need not to be suit to super tight or else I discovered that they will actually flex the circuit board a little bit and have caused a little bit of problems from time so once we get them screwed in we pop the speed thing off and then we just check that one is still tight this one is okay and that is basically it so see if this is actually just some way I could reset the dang I don't think I can I think I've been down this road before so it's just gonna be voiceover till we get to the end but you know it's step by step it's frozen okay but in any event this thing is gonna boot still takes about 90 seconds but if we're lucky it should come up cleanly I had to well you know there's all kinds of details of course this is the process that I'm assembling is actually a fair bit different than what was so you know I built a tile alright here we go there's the Linux we have a new what test pattern that comes up first which I started using for color grading when I'm shooting with the Fuji to try to actually get more accurate color than what looks like the webcam is producing for us and so we get something like 15 seconds of that whatever it is and then the engine starts up and out of the box it's running you know a huge gene because that's always a favorite come on you can do it okay so that's it so this is G247 in the the new G series of tiles I you know so that gives you a little bit of a sense of how long it takes unfortunately the slowest part of it is the flashing the software the good thing about that is if I work hard enough and just work hard enough if I just figure out you know a suitable number of USB adapters and so forth I could actually do that in parallel and do it like the way I did here which is you know just get the Beaglebone ready to go get the fire get it all flashed and put it back in the box with its information on it and so forth and then the assembly goes much quicker because here it is so here's our little feet that go into the frame that holds it all up boom there it is okay well you see this ought to be me I mean you can actually see my chair I think it's the exact moment that it died in any event so be it happy holidays happy new year 2022 I don't know it's all unbelievable I will be back in two weeks my goal is to get through 2021 okay I actually have had a little bit of fun and that's like a good thing to do and now that I have refreshed all this I want to knock them out I want to you know I should be able to do a half a dozen a day without even really cramping too much so we will see what we will see and I'm gonna stop there so thank you for coming by and I hope to see all again soon I'm gonna go over to the chat room and see if anybody's still around thanks for coming by
