 All right, Lady Aida, what is this everybody and welcome to show and tell it's me and Lady Aida with me Mr. Lady Aida, we're here at the Adafruit factory. This is where we do all designing and testing and shipping and coding and kidding and videoing and script writing and and Little bit everything science investigations And right now it's quiet because everyone's home except for us because it's time. I'm sorry to show over It's time for us to do show and tell we're gonna see what's up with people in the Adafruit community and The general maker community with their hacking soldering sewing and more. Yeah, let's start off with JP Yeah, lots of cool stuff this month, too. So come by if you're building your Halloween costumes That's all year long, but this is a good month any retro stuff every Wednesday 7 30 p.m. And if there's times when we're not here, we have our co-host and more so you'll see some of the team all throughout the year Every single month every single week show and tell we have some of our staff JP, what are you working on this week? Hey, I'll tell you what I'm working on if you will share my screen I can show you too. So these are these super cool snap apart Key switch matrix boards that we sell these PCBs you can snap it apart to make your own shapes and designs but this is the six by five six horizontal five vertical layout and All we give you is some pads to solder whatever you want onto here So this could be into a keyboard or another microcontroller We have the column and row diode matrix and we also have Neopixel and power and data and all that stuff But I've never really used it for anything bigger than just one of these until now because we have This super cool expander, which is this TCA to 418 Which goes over I squared C using STEM a QT to your microcontroller And I found a way to gang up two of them so that I could have Two of these I think this will do it most like maybe a 10 by 5 or something like that It's 80 keys so 8 by 10, but it was like I figured you know This would be good to show having a split keyboard Right and that's some people want to do and it's never that straightforward because what do you have like two microcontrollers? And are they talking to each other over? Serial like how do you do all that? So this is one way that I came up with of having a pair of these TCA 84 18 so each of these kind of goes to his own little keyboard matrix GPIO expander And then they go each to a different I squared C port on a RP2040 based QT pie should work on any any board that lets you use two I squared C Buses to separate course because these don't have separate addresses the way they're made it. This is a TI right who makes this chip? Yeah, it's a TI. I think TCA is TI and yeah It's a fixed address and I was like I figured like instead of having a multiplexer I was like, oh, you know, I think even you were like, hey, you know, there's two I scored C ports and it works One of each and you can yeah, so I'm making a cool little Ortho linear so not staggered ortho linear and I I'm finishing up the code on it. It works I have it working as a USB keyboard with Some modifier keys and I'm working on doing layers so that you can you know One of things people do when they have these very very constrained keyboards is they learn, okay We're used to hitting shift to turn one into an explanation point But why not hit like the lower to turn it into a function key and and so on so Complete like you've got you know all the quarter you got you have a space bar, which is great, you know I know I think yeah, I think we worked on like the one of the pickle boards and it didn't have What is this what is this aesthetic is like 2001 space Odyssey bank teller or like no, I like that a description of it Yeah, it's it's a the color scheme here is an inverted callback to the data general Dasher turn Totally like yeah, like a like a definitely 2001 space Odyssey, you know, yeah, there's something there's something IBM about it something very cool and ergonomic about this Maybe super wide shoulders and you need your I think it's the dark blue. It's also the Q. See how the Q is like yeah Symmetric. Oh, that is so right It's something about this. Yeah, and the shift. I don't know those are those are some great. There's some great keycaps One other thing about these is These are double shots. So there's two plastics Oh So this is never wearing off. This is yeah forever. We plastic that's forever. Yeah, okay. Yeah in the discord chat There's a really beautiful Data general keyboard and terminal that yeah, that's that's the aesthetic That's beautiful. It's exactly the same color. I don't make them like there. Oh, it's gorgeous That was actually something I became aware of because of that TV show I Is it severance? Yeah severance is yeah, there's a lot of folks that watch that for retro computing ideas Yeah, they made some good to start of modern not modern They made some crop versions of those that did what they needed But it's really based on that that one that you're showing in the chat. That's super. Yeah So that's what I'm working on and I'll be building a 3d printed case for it So that it's a complete thing And tie in these guys down there's some mounting holes and then the cool thing is you get to just Hair the two with one I squared C stem a QT cable the one I have here is extra long It doesn't really need to be that long and then they'll just be for a connection to your computer And then you can clack away like it's 1967 Cool, and you're gonna show this off tomorrow on your show. We'll do yeah come by for that and some Cirque-a-Python parsec and recap of the product pick of the week and other and on maybe a Guest appearance by Lars. You never know. Yep. All right. Thanks so much. Okay All right, thanks, JP Beautiful keycaps. Yeah, all right I lost the window that my demo is in because I was busily busy Tuning this keyboard Evolution and revolution. So you're stepping, you know, you're both kind of yeah, what do you got going on this week? All right, so we're back with the pico w and this week I have implemented a secure sockets So before now we could connect and get a basic text Version, you know text thing and this is all gonna be text, but it's just on an HTTP website Yeah, so last week this would not have worked to get the quotes from the a to fruit API because it's your website So we are you know connecting out we're getting the certificate verifying a to fruits identity and continuing on and You know, this is just text, but you can fetch JSON like this huge Thing somewhere in here is the number of stars. Well, we've got 128 subscribers and network count of 57 78 So yeah, it's a star star watchers, but it's our star gazers count Stargazer count 15,193. This is micro python. Yeah No, this is circuit It may be it may be gathering different information. You are always circuit python. Yeah But yeah, so and then you might ask well There's SSL, but does it verify that my website is good and there's a cool website called bad SSL And this one for instance sends back a self-signed certificate. So you easily check that your software isn't just blindly That's a good idea Accepting whatever the site is sending back Yeah, so and then you know Circuit python.org works github.com works a to fruit works Google Google duck dot go not that there's anything you could really do on those from circuit python But a lot of websites work and there's an open pull request for this and with any with any luck tomorrow There will be a uf2 on it that folks can download and start testing It works just with like it should work with our request library and all of our example Yeah, it's a request. So if you're which is based on the Python request library and we did a lot of work with it for like it handles redirects and What's it called the thing you need for Twitter off Had her things headers. Yeah, like the header additions and tokens The tokens that you need for Authentication so actually will be really neat is we'll do a run-through of all of our like we have libraries to get like weather Data and tweets and like stocks and stuff So that stuff is based on our request library. So it's just all work It's another example of learning Python once and you can do things as we had Python powered things with screens We need to display stuff. Yeah, this doesn't have display. You could just but I can't Make a display to fit right on Yeah, we probably are we probably we probably are coming soon Okay, yeah, it's starting to work and as usual. I'm really excited to share that with y'all Excellent work job. I mean, this is so exciting, you know I know people have been waiting for this for a while and and we wanted to get a bunch of other stuff done and of course People a lot people were on vacation in August, but now it's fall time to wrap it up We have a couple more things after this like being able to handle cell science certificates if you Pass in the certificate file if you explicitly do it Yeah, and then and then client certification But you know, like I said, I think we mentioned the meeting 98% of people want to just be able to connect to a certified You know TLS 1.2 site The only thing is it so I saw circuit Python the disk drive changed, right inside Yeah, so because we need a lot more space for the circuit Python firmware itself I've smushed the amount that the circuit pie drive gets out of the total flash So it used to be you got one meg give or take and now you've got only a quarter of that And I may be able to increase it back to 512 and kind of split the difference We'll see and so that's a big caveat about trying out this poor quest is back up your circuit Pie drive first because it is gonna have to erase that to switch from the one capacity to the other Yeah, I mean last thing is I really appreciate all the folks who are helping and chiming in especially with short Scripts that will help demonstrate something that isn't working for them. It's super helpful Yeah, look back around to those book reports after we've kind of gone as you said gone deep and get the features that we want Yeah, I can fix the bugs and Yeah, finally for anyone watching if you do try out the poor quest If you find bugs, please post Small concise repeatable snippets it would really really help us it helps Especially if we don't have to have a cat password either like oh, I'm trying to get to something It's password, but I can't share the password. It's like that's really tough for us to test and it's hard sometimes I mean so if If it doesn't work, you should tell us it doesn't work But if you can boil it down to something that we will be able to easily test that helps so much and it makes our Heart score three sizes on our chest all right excellent progress and I know a lot of folks are waiting to use their Pico W's because they use your Python including me Thanks. Yeah. All right next Liz what you got going on this week? Hello So I've been putting some projects into Pilate for a couple of guides using the clue And this is the badge project is gonna be added and the only thing though for custom badge You want to be able to update it with your information? So there is the app file glider Fix my focus And so right now the clues connected to file glider and this is the code that it's running And so I'm gonna update it in case my cat wants to use the badge. So I'm gonna change it for her name Which is very possible So we need and then all you do is you press save on the app and you'll see that now the Is updating live in real time and now it says Winnie and cats So this is actually I just downloaded this today. It's first time I use it It I'm impressed how like fast and stuff. It is very cool So a guy will be coming for this soon showing you how to use with Pilate and file layer. All right. Nice work, Liz Thank you Liz. Thank you Liz. All right next up. Let's go to knowing Pedro. How you doing? Hey folks We're doing all right this week. We have an LED noodle project We got all of the colors. We figured what can we do with all the colors? So we put them in a noodle lantern So we got our noodle lantern here. It's a 3d printed Kind of container inspired way like some sci-fi props And they're all pulsing. They're all wired up to the Qt Pi RP 2040 and it's using a pvm to Kind of fade them in and out Yeah, we also put The battery add-on BFF on the bottom so that we can recharge the battery so it's portable and we're using like a piece of Transparent film to be kind of looking like this kind of glass thing. It just wraps around there and just have some tape holding it But yeah, the noodles are really fun to play with and what was gonna be just the test shape ended up being this So I thought that was kind of clever As a prop, you know, it's got it's it's like it looks like it's definitely a sci-fi prop But it's not clear what it's from and I kind of like that when it's like It's evocative. Yeah, Riddick is always hiding me so people can't get off the planet before the monsters Yeah, it's like is it is it a bomb? Is it the key? It's like use that fuel cell fuel cell Yeah, it can be it can be so many things Yeah Yeah, and the noodles are really fun to play with so We'll probably revisit that and make some other projects with it, but this is kind of a neat kind of use of the filaments Yeah, the Edison Style lamps are really fun and I kind of got inspired to kind of these weird shades Yeah, and for folks of us, it's not like EL which has that some folks don't like the noise it makes So this is really silent. Yeah Yeah, and they're they're pretty bright. You can wire them in different ways Yeah, this big thing. All right, right on. Thank you so much. Thank you All right, and what you got going on? Hello, welcome back to show in town. It's been a while, but hi. Yes I'm here now and I went to the Halloween store and spent some money on a few things I've started getting some ideas and Just to get out of the gate. I took a a crow outfit and outfitted it with the Adafruit monster mask and Downloaded some really nice matching eyes from the tutorial on it and You know Did a little crafting and here it is so I mean looks great. Yeah, I mean it's wearable or Last thing about putting it in my window and freaking out my neighbors and things like that so So things are going. I like that one and then Over here I have a astronaut helmet that I got the same store and I've got a Skeleton mask that I've had forever and I'm gonna put those together and make a Scooby-Doo Ghost Ghost from outer space that of that episode when I was little and I've always wanted to kind of recreate that one. So it'll it'll have sound it'll have light. It'll be great Would have gotten away with it except for you pesky kids Yeah, and your dog tail dog. All right, and thank you so much. All right. Thanks. Come by. It's good to see All right, and then last up this week. We'll close it out with DJ divin 3 what you got going on. Hello. Can you hear me? Yeah, yeah, okay. I have a whole bunch of backpacks Three of them are the new stemma backpacks and It's really hard to see This guy. Yeah is the new Hub the step up. Oh, you're using it right absolutely great wonderful The white ones are the old style and they required a little bit different code for initialization And I want to send a big shout out to Melissa who put in a new Library update that allows the backpacks to be just one large Number one large string That was so helpful So I will hit reset on because I I'm dealing with the hard reset bug Is that gonna work? Okay, and now this the white one will go out to YouTube. It's connected to YouTube API that I wrote from scratch and should Once it connects to Wi-Fi Pulled down the amount of So that's how many views I have on my YouTube channel and then after 60 seconds it will switch to how many subscribers I have A lot of views. Yeah, and I plan to do the same thing with the the blue for the Twitter I'm guessing yellow for Instagram and then event I'm gonna switch the red to YouTube and then I don't know have white for github or something else. Yeah Yeah, it's gonna be API land for this for this project. Yeah, I think yellow stars to do discord For purple for users online. There's all sorts of things I haven't thought of that. Okay. Yeah. All right. All right Use of a new product and a bunch of cool code All right. Thank you. Yeah. All right We got to everybody. Yeah, that's our show until this week. We'll be back next week 7 30 p.m. Eastern Standard time. Thanks so much everybody for joining us. It's our favorite half an hour of the week every single week A bunch of cool projects came in and more come by this month Just like every month pretty much is like Halloween, but this month in particular. I know It's spooky season come by and show off anything you're building. It's how we're wearing black. Yes This week, this is the eight for dress kit. So we'll see everybody on ask an engineer in just a few minutes And we'll see you next week. Bye everybody
