 Hey Liz. Hey John. What time is it? What time is it? I think it's show and tell time. Absolutely. Let's bring in Kevin from DigiKey. All right. But you're muted, Kevin. I'm muted. I hate that. That's the first thing you got to check when you're on a live broadcast. So you're muted. So we're on show and tell. It's good to see everybody. Fantastic. So what's going on in your world? Just this right here. This is our first time co-hosting the show and tell. We're excited to talk to you and hear what's going on with you or see any projects you might have brought. Well, yeah. We've got a lot going on. It's been a couple of weeks since I've been on here. So, you know, DigiKey, we're starting to all go back into the office here and there. And that's such a good feeling to get that culture back and be around people. And we were able to work as a team and kind of demo with each other. If one of you wants to share that image I had. This is the real modern DigiKeyer. You know, DigiKey started by creating a digital keyer for Morse code. And we're trying to recreate one with more modern day components. And it's really cool because it's an entire product. You do see a feather with a feather wing on it. Yeah. We haven't got that working yet. But besides that part of it, the entire keyer is discrete components and using 555 timers and trim pots and all these different gates. So you can have the dits and the does. And there's a headphone jacks. You can listen to it. And then you can actually do like word counts. We're going to have word counts display on the screen. And ultimately that feather, it's the, I think it's the ESP32. Maybe the A266. I don't remember. It's going to be Bluetooth. So we can communicate with the cell phone on whatever you're key and whatever your message is and your key or speed or whatever. It's just a fun project. So that will allow you to send Morse code, which could then get either sent straight out or interpreted on a device. Right. Yeah. Yeah. You can use it for fun things. Like I said, just doing interpreting the speed and whatever words you say, you can do however words per minute. But we had a lot of fun playing with it in the, in the office when we were back there. So it's, it's coming along really well. And we're, we're all really excited for it. So I'm hoping to keep sharing this as we, as we do more show and tells and talk a little more about it. The, the cool thing, which not a lot of people know, and I don't even know if I'm supposed to say it yet, but the titles that we made, we're actually making them look like the Digi-Key ruler. It's going to be basically a cut out of the PCB Digi-Key ruler just for the, I don't know the legacy aspect of our ruler. It's going to be pretty cool. That's really neat. And are those flexible parts or capacitive touch? So actually here, let me share one other image and you can see it a little better. Chrome tab. Sorry, I should have this ready. That's all right. This is how we get to see top secret leaked stuff. So what it does is, Oh, did I share it? Yeah. Okay. So you see that screw with that copper washer. Yeah. Copper washer on it. They actually touch that. And the, the red 3d printed part right here is actually a cam. To adjust how tight it is. So if you want a little bit of play or a lot of play. So there's pressure against the cam. And then as soon as it touches that screw, it makes contact. I see. So it's a little flex. Yeah. Yeah. And then you can see the, the headers for the feather and then the feather wing. It's pretty cool. And then we added the connector. It's kind of a cool right angle connector to power it. Cause when you put the feather on, it covers that connector out because the feather doesn't have back, you know, we want to power it through the feather, not through the board. Oh, neat. Cause it's some protection thing. So we want to cover up that and make sure we don't accidentally plug it in. And it looks like you have a couple of a Phono TRS 3.5 millimeter ports on there. Is that right? And how do you use those? Yeah. One of them is the, for the headphone, the output and the second one, it was, it was actually an input. So you can input sound into it and display it on the, I actually know it. So you can talk back and forth with two different keyers. Okay. I like to put the audio out through some effect pedals. Maybe. We're all. It is. It's really cool. When you put the headphones in and you play on it, it's like you're watching like an old movie, you know, we just had a lot of fun at the office that day. That's fun. It looks like some people over in our discord are now communicating solely via Morse code. So we'll have, I'm going to have to learn a lot more. I've been trying to kind of learn a little bit about it and how it works. I did learn like SOS. So the, the DOS actually override the dits. You can hold the dits and then just tap like, if you, it's three, three, three, three, three. So you can just hold the one and just tap the other. So it's a little less confusing, but it's cool. Anyway, like I said, it's been a really fun project and I'm glad to be a part of it. I'm glad to be able to share with you guys. Thank you so much. Well, we'll, we'll look forward to seeing it as it progresses. Thanks so much for coming on. We'll see you next time. Sounds good. Take care. Okay. Oh, let's add in. Hey, guys. Hey, it was great to see you on the other side of the screen. Awesome. And of course, Happy May the fourth everyone. Yes. Yes. Oh, I just noticed that I'm like getting all the, what is it the mosaic effect on anything? Let's talk about this Q. Yeah. Yeah. This is this week's projects. This is the collab project with Phil D. He wrote the code. This is running a Raspberry Pi four and the RGB matrix on it. So there's six of these RGB 64 64 panels. And he managed to get the code to run across all of these lovely panels. Pager, do you want to hold this while I run through a couple of Yes. Weird demos. I think I know what the first word is. So this one's using the LIS 3D H accelerometer. So that's like our kind of hero classics. Can you mention that this is not fake. A lot of the ones that we see out there, it's like one panel. It's like, oh, look at my cube. It's like just one side. So let's prove that it's all sides by loading it. Everybody's favorite character. Who is it? Hold on. Dang it. I can't accept it. Take the anticipation. Who is it? Everybody's favorite mascot for John. Show. Oh, no. Everybody knows. I'm trying to show Lars. Get him out here. Hold on. Where's the cane? So the way to run these demos is through terminal and using SSH and we're kind of streaming. So that's why it's slow. Like why is this working? There it goes. All right. I should have worn a shirt that I could put over my head and be like, ah. Yeah. One of the weird things with the RGB matrix panels is refresh rates. Always an issue with webcam. So it kind of looks one out. Let's see if I can bring it in. But this is again, super thanks to GP for this. Sweet. Yeah. Unwrap UV texture map of his entire head. And your chin as well. Like this is uncanny. And I like your joke on what you do to get your mom for Mother's Day. No, I know. I think she would like that. Yeah. Any models of that. So here's Lars. Hey, Lars. And all sides. I mean, I guess it's kind of easy to do all the sides when he's all. Yeah. He's an easy one. Seeming edges. This one is so cool. Because it proves that the earth is flat as a cube. But it can be. And all the polls, of course. We have a massive guide that went out live this morning. So definitely check it out. Folks want to take a look at all the bits. Folks were talking on three hangouts this morning about different ideas. So definitely take this as a kind of jump off point. If you want to make your own, you can use some of the bits that we have. A quick demo. Do you want to show? I don't know. Is it the same? That's the top, right? To show how the magnets are all connected. Yeah. So that's why I have this one. So this is what it looks like with just one panel. But yeah, all of these have magnets. So they will snap out and they have these labels. These, these labels, you just line them up like. And that way you get the order of the panels. Correct. And I did not correct. Wow. One of them. I'm building another one for Lamar and Phil to have so they can run all sorts of fun demos too. They got some. So yeah, check it out. We have the panels in stock. Sign up for the Raspberry Pi. And the bonnet. We got to end it with one last demo. The, I mean, it's, you know, it's made before. So let's get a death star in there. Let's do a death star. I think these are one of the ones we get away or probably not, right? Because of the copyright stuff. Right. Yeah. We show Philby wrote a nice little section of the guy and how to resize and create your own images for this. So definitely check that out if you want to make some of your own images and texture maps. That's so cool. And of course through a fresh rate, you know, it looks. Yeah. Buttery smooth in person, but yeah. Super cool build to keep you occupied for quite a while. But it's quite the documentation process. So thanks for the code. Yeah. Yeah. Two different sizes you can build. So it's a nice long guy. I think that's all we got. Thanks guys. Jeff next. Hello. Well, I had a demo I was going to show tonight, but it wasn't working for me before we went live. So I thought I could talk to you about Python. Yeah. And by the way, John, I met you in person. I know you have a lot more neck than it looks like on that cube. So, you know, good job being a volunteer for that little experiment. But yeah, I've written a blog post about it on the Adafruit blog and just kind of wanted to cover two of the highlights for me. First of all, well, three, first of all, just being back with people. We all wore masks the whole time and everybody was being as safe as they could. But, you know, you got to be around people. You got to have chance meetings and just hang out and Katani and Melissa introduced me to so many folks. The names, there's just so many names piled up in my head right now of people I got to meet. But there was a keynote given by, I'm going to say her name is Sarah is soon from the event horizon telescope collaboration. They're the ones who have made the image of the extra solar black hole that was released a couple of years ago. And she talked all about how Python is important to the way that they work together and collaborate and process the data. And that was really cool. I think that will be up on YouTube, you know, when the talk started appearing from Python. So figure out where that is and watch it because, you know, hearing about the way these people collaborate and how Python plays into that was really awesome for me. And the other thing that was a lot of fun was the Pilates dinner and auction. The people in this community contributed a tremendous amount of money and bought really cool stuff at the auction. There were some, some, this piece of art that just blows my mind. They went for several thousand dollars. And yeah, there's a link to that in the blog post. It's called slime mold maze and it's, it's art. It's a maze. It's proven to be a unique maze with Python. I didn't understand it all. Somebody spent, I think, upwards of $8,000 on it just to give an idea of what they were doing. So they raised $40,000 for Pilates, which, you know, is all about enabling people who are maybe a little less seen in open source to participate more. And yeah, so I think Python was just wonderful. And I've been saying thank you to Adafruit for sending me and letting me represent y'all. And yeah. Sorry, there's always just one more thing. We did open spaces where we invited people who had maybe never, you know, used a microcontroller before to work with a circuit playground, Blue Fruit. And like by the end, they would come in and they'd say, oh, I don't have much experience in Python. I just don't know. And then they'd say, my light farman works. Look, it makes this, it makes this sound. I can kind of play music. And they were just having such fun. And I loved it. I love to kind of help enable that. Thanks for doing that. And if anyone hasn't go to the Adafruit blog and check out Jeff's blog post. Yeah. And I will drop a link to that also in our Discord. So hope to see you there. And I'll be hanging out a little bit. Thanks so much. Thank you. All right. So keep it to two minutes per person for the next couple of folks. And we'll be good for Ask the Engineer. Next up is going to be Flummy Guy, Tim C, and Tim C's screen. Tim. Let's get them out. There we go. Hello. So I'm going to be playing a little game of Picon. Katnien, Melissa were out at Picon. And one of the things that they asked about while they were there was being able to play a little snake game. So I was not there, but I was helping out online and playing around with some different stuff and doing PR reviews and things. And I ended up making this little snake game with a nice Blinka snake in it. And the game itself is fairly basic. But one of the things that I thought was really cool about this is actually if we finished the game, and what I ended up doing was integrating this with the sort of standard badge example. So that like pie badger example that has the hello, my name is badge and the custom image and the QR code. And you can kind of cycle between all these things. And now you can press the select button over there to have it launch a different program. So I had to launch the snake, but you could have it launch actually anything that you're working on. So this is a great way to show off not only your badge and your info, but whatever you're actually building on your pie badger pie gamer device. That's really cool. And is that code available now with this launcher for? It's published up under my GitHub, but I am planning on PRing the example in that pie badger repo to kind of show how you can launch that out. And then I have a separate repo for the snake game right now. I just happened to have one of these out. Nice. I was preparing to do something with coincidentally, so with more to it. And I will say also really quick thank you to all the folks out at PyCon. Jeff Katney and Melissa as well as all the sprinters. We had lots of new folks get involved and submit pull requests throughout PyCon. And this was their first time working on it out there. So thank you to all of those folks who worked on that stuff. Excellent. Great to see more folks getting involved. For sure. All right. Thanks, Tim. Yeah. Thank you. Next up we're going to go to Mark. Hey, Mark. Hi. So speaking of getting things working at the last moment. I've been improving my little insect bot over the last week. I love this. Yeah. So it's now moving in more set increments. And I've since got the little panel vice thing with the servo's on it moving and moving the ultrasonic sensor around. It's so cute. Yeah. What I ran into and the whole reason there's a USB cable in it right now is power issues. And I believe the servo's in the tilt device actually require five to six volts and the battery just wasn't cutting it. So it wasn't working. So and then I just plug grow cables into everywhere. Yeah. And the other interesting thing, I don't know if it'll be easily visible, but everything's now on a little proto board. That I was trying to use to see if I could design a small circuit board and PCB that later can mount things to not that there would be a lot to it, but potentially now a voltage regulator to get higher voltage if required. And just all your pin connectors. So rather than have to have them everywhere, like even here sort of is they can just be organized and it could just be built into the 3D enclosure. That's great. It's nice seeing the evolution of this look forward to your next iteration. This guy's adorable. Yeah. Yeah. I love how organically he moves. Yeah. Thanks. Yeah. That's kind of the bit. And it's probably about to walk off my table. The sensor is not yet working. Yeah. Thanks a lot. Thanks, Mark. All right. Let's next go to Todd Bot. Oh, hey. Hey, Liz. Hey, JP. So I, you know, woke up this morning and realized from my Twitter feed that it was May the 4th and Star Wars Day. So happy Star Wars Day. And so I quickly, I quickly whipped, whipped up a little tiny targeting computer. Yes. Yes. That's, this is the ESP 32 TFT feather with a case by JP. And, and then it's in circuit Python and it's just got two little animations going that the like sort of centered grid and the little lights in the lower left there. And yeah, that's really it. It's pretty simple. Yeah. Shit. Don't turn it off. Don't turn it off. Oh, shit. Oh, no. That's really cool. And actually that's a Rue's brother's design for that case that then I've modified and probably you'll modify it. It'll, it'll evolve in itself. It's a good case. The little top part does come off pretty easily though. Yeah. You gotta refine some colors and do some extra width to get that snap to working on your prints. Yeah. Yeah. It's pretty cool. And I imagine you could hook this to your glasses so that you can always be targeting. There we go. Yeah. Or I could be like, like a Lobot on a club city. All right. Thanks. Yeah. Good one. Next we're going to go to a Flavia. Hello. Hey guys. You hear me okay? Yes. Yeah. Oh, cool. I just thought it, I'm a big fan of all of you. I mean, you just looked at me and all the things I have around. You know, the meaty fighter lives, you know, and the part sex and everything. So the reason I'm here tonight is because I want to share a project that I did is like a pet project. I have an electric car and now going back to the office, we only have six days and there's a lot of folks with electric cars and I needed a way to see how, you know, how available the base were. So, so I have a matrix portal. Yes. And thank you. So I started off by writing this little script that basically patches, you know, the information from the base, you know, it's, it's, it's called a SEMA connect. That's the provider that does that. And then it's just a little script, you know, and then it pulls in the information. It creates a JSON file that I can actually use. And then from the JSON file, and then I have it running on like a timer via some specific times. But the fun part about it is that with this thing, I can populate Adafruit, right? So with Adafruit.io, I can, I can have my own feed, right? So I can push in Adafruit.io, the feeds, and when the beta comes available or not, I can have it displayed. And that's what I have here on that. That's the little portal. So I can do a little demo. So let's say, you know, the, you know, it's the morning and the cars start coming. And then I can just by having pulling the JSON file and updating it, I can see that, you know, the base got easy, you know, and then things get read. And then, and then it can go more. And then I have a little, and then that was it. And I share with the folks in my work, and they all liked it. And then I said, okay, you know, what else can I do? So now I'm loading this up onto a little matrix portal. And that came out really well. And it's really fun because with that, I can basically, and I have it right here. So what I'll do is I'm going to switch cameras, but you can see a little better. Hopefully I won't mess up. Setting, yes. You want us to remove the second image? No, you can leave it there. So, so basically what I did is now I have this little guy and I'm using the accelerometer in the, in this display to, to make it, instead of periodically pulling the data, you know, being able to go in online and fetching it for me. And as you can see in a minute, I think you will, let's see if that works. And while we wait for that to update, what I may have missed this, what is the sensing of the Bay availability based on, is that something that's already available online? Or are you adding sensors to the parking spots? How, how are you getting that? Yeah. So the, the, the sensors are my work. That's called SEMA Connect. So I pretty much don't tell this to them, but I reverse engineer their API. And then I figured out what I needed to do, basically using curl commands. I'm able to pull down the data, you know, and that's smart. Yeah. And that's pretty much it. So I'm just going to make it over the data here. See if that works, but anyways, what he would do is go online and go to the Adafruit and pull in. There you go. Now I have a bunch of days used. And then if they're all busy, I make it like a little red blinking. So it's time for me to move away my car and make room for other people. Excellent. Yeah. And then I'm using the, yeah, so you can kind of blink like that when things get busy. So I know this can probably pay attention. And then the last thing is, I'm using the, the progress bars, right? That I think Hugo, right? That puts together and that works great. So I could fight on. So the, the only caveats I had is I couldn't really use the make expert library as it's only because I didn't have enough memory. So I was thinking of the, the RP 2040, right? I saw that you guys, not you guys, but you sell at the interstate 75, but that doesn't have wifi. So I was wondering if later down, down the road, you're going to have an interstate 75 with an ESP 32. That would give us more memory. Yeah. Yeah. And that's it. Thank you so much. Great demo. Because of you guys. So good times. Great to see. And Clive's been a useful project too. Yeah. All right. And last up, we have Leo. Are you there, Leo? We lost Leo. Okay. Then we are done early. So people will have a chance to go grab us. Snack and hunker down for an ask an engineer that's happening in about five minutes. Yeah. All right. Thanks everyone for showing your projects. And we'll see you again next week. 7 30 p.m. Eastern is a 4 30 for specific. Yes, it is. Awesome. All right. Thanks so much, Liz. Thanks, John. Thanks everyone.
