 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. This is the ninth update of the T2-Tile project. Let's get into it. I made another T2-Tile using the new printed circuit board that came in a week or so ago. It was meant to test out this idea of having a light sensor so that the T2-Tile could maybe detect if you waved a hand in front of it, something like that. Also to go to mounting holes in the corners and a bunch of other small revisions that I made as well. I made a video about that. Let's take a look at that first and then we'll talk about other stuff. But my thought is, is to just go ahead and try to see if we can solder one of these things up today. And solder it up by hand rather than trying to use the stencil right now. What the heck is the camera? But look at that. Absolutely huge. So what are we going to do about that? Software guy lost in hardware land. I'm going to change tips which means I have to let it cool down. So I'm going to stop the video. I'll try to get a picture point. I also found this, which I suspect is the fuse I was intending to try. A gigantic footprint power supply crossing. But at least it's another test. I haven't tried this yet, so this is our power supply. All right, I see. I've got a Beaglebone green here that I took off a known good Tile. It's going to take a fair bit of force. USB port crashes into that J10. Still, if we need to, bam. I also found a new software to be written before we can actually test the light sensor. So all of that is going to have to wait for another day. So all right, there it was. There's an awful lot of testing left to be done. Don't really know what the connectors were and so forth like I said at the end. But overall, the case mounting holes look reasonable. Here it is with some brass standoffs in it. These are the M3 things. It's a little bit tight, but it appears there's enough clearance all the way around that I'm especially close to one of these. This guy is close to the Northeast buffer chip. But I think it's going to clear all right, so I'm not going to worry about it. And I think there's going to be enough room to redesign the case around these guys and have it be, we'll see. That's going to have to get the 3D printing stuff going again real soon. There's a bunch of things that need work, obviously. The J10 header at the end is going to have to be moved. The footprint, I've got to decide what I want to do about the fuse. And the Q4, that's the light sensor, that's not hand solderable. And it really brings up the basic question that I need to face that I haven't faced, which is there are these footprints that I was talking about, these things here. You see these, so there's a black area in the middle, that's where the chip goes, but then there are these little silver areas, which is where the pins go for the particular chip. And the ones that you see here that have actual sort of visible stuff extending away, those are footprints designed for hand soldering so that they're a little bit longer so you have room to get the soldering iron in there and heat the pad up and get the whole thing to go. But there are different footprints for reflow soldering where you put the stencil down and you put paste over the whole thing and then you put all the things on and you throw it in the oven. And I have sort of a home version of reflow stuff set up. I've tried it some, I've had kind of mixed results. I think part of the mixed results was that I was trying to do reflow soldering on footprints that were for hand soldering. So the question is, is it time, am I ready, am I terrified to commit to changing all of the or most of the footprints that I'm using currently for hand soldering over to reflow soldering and going again. Which would basically mean that sort of my advanced beginner skills in soldering iron stuff would become much less important and my almost non-existent skills in hot air rework would start to have to get shined up. We shall see. That's for the future. But the board does work. The board does boot. That's pretty good. Okay. So beyond that, there's a whole lot of news out in the world related to T2. I want to mention it all very briefly. First off, we now have a T2 subreddit thanks to HeyAndyX. I mean, as I start meeting all these folks who are interested in this stuff and they're doing things which on the one hand is just so incredibly super great and it gives me the energy and hope and everything to say, let's do this, let's do this. But I'm also seeing people under their handles and under various pieces of their names and I'm not exactly sure how to refer to people. So if I'm not saying the handle that you want me to use, just let me know. HeyAndyX is worried about whether the T2 tile subreddit is going to sort of just steal traffic from the YouTube comments. And on the one hand, I understand and I'm worried too. I think the YouTube algorithms, you know, they like seeing comments or at least they like seeing certain amounts of comments. I don't know. It's all the magic at this point. So it would be sad if we didn't have any questions, comments and so forth or any actual YouTube comments that go with each of these weekly updates. But on the other hand, for actually having a discussion and going back and forth and linking this stuff and so on, YouTube is not great. The T2 tile place could be a place to orient around that. And I'm hoping it will be there, you know, step by step. So that's great and thanks to HeyAndy. In addition, Michael Wilding set up this Gitter thing, which is like Slack or one of these chat room kind of things. I hardly even know the names of them all. This one has the particular advantage that it has relatively tight coupling, although not corporate coupling to GitHub. So you can sign in with your GitHub credentials and then I don't know, do something, you know, have stuff work better. Folks have already shown up all of our heroes, Andy Walpole and HeyAndyX is there and so forth as well as Joe Collar. People talk about it in a second. I have notifications turned on for this thing. So if you say something in the T2 tile library and I am on the machine, I will see it sooner or later, probably sooner. So that has already been helpful. And I think that has encouraged about if you're more development-oriented and you want to know just what's going on or you think you might be able to contribute. For example, if there's anybody who has high art skills in Linux kernel modules, we really need you soon. The T2 tile lobby is the place to go to find people. The Earl is there. The Earl of the subreddit is also there. One of the things that happened already on the Gitter is that Joe Collard who I've known for years and years, he was at UNM way back when IJSF and Isaac Clarke have been kind of working in various bits and pieces on actually getting Docker containers going for to get MFM running number one to sort of just, you know, one click go on Linux where it will work best, but also getting it run on Windows 10 and Mac OS. And that actually appears to be working. It's not super fast on Windows and Mac because I guess it's running in a virtual machine, but it's there to play with. And, you know, on the one hand, anybody who knows me knows that I'm pretty much of an open source zealot and I'm always trying to encourage people to, you know, find their way out of a dead-end operating system into Linux or at least into open source, which will allow us to survive embedded in the land of T2 tiles and so forth. On the other hand, I can tell from my demographics and my statistics and stuff from YouTube and whatnot, the number of people who are watching from Linux is a rounding error compared to the number of people watching from Windows. So this would be a way that you could play with MFM and ULAM a little slower than, you know, maybe you'd be interested in trying to set up our Linux box. Who knows? Okay, but that's great. Thanks to Joe and AJ Zaf. The Ubuntu packages have now been updated for almost all for 16.04, 14.04, 12.04, something like that. I'm trying to have them up shortly for 18.04, but they're not quite there yet. And that's the main events for this week. Next week we want to have new revs of the board ready to go and we want to have the current thing tested. It will be out in one week. Thank you so much for watching.
