 And we are back That's right Miss Lady Ada and Mr. Lady Ada here hosting the show in town Broadcasting live from downtown Manhattan where eight-foot headquarters is we do our manufacturing kidding and shipping and coding and videoing But enough about us. It's time to talk about you people come by we're gonna see what people are up to what are you making crafting 3d printing? We're in discord. You can get the link to join in the stream yard. All we need is a video Video camera and a mic in a project. We have some folks from our team But I see Keith is here with an engineer helper So let's start with Keith and then we'll go to our team the way we In case it's bedtime for the engineer helper Hey Good they're showing off the run girl. I made I made for this one's birthday This is Ada. So when she was going to best buy one day, she saw these headphones She's like I must have these that's all she wanted for a birthday was these these carry your headphones Which of course what she wanted it for was to play music And of course there they're actually for a they're actually for Gamers, they're like meant to be plugged into the computer. They only come with a USB plug So of course, I knew she wanted to listen to music with it. So before birthday. I just sit down and make this thing Which basically you can see it in there. So there's a Raspberry Pi down the bottom there And then there's a there's a pack of it up the top on the other side. There's a Qt Pi Running circuit Python to talk to the front end I haven't got the screen day doing anything yet except showing train bundle cat that the end I didn't break it to the animations for the birthday She can turn around and like this plate plate pauses on this one volume She holds down that that shows down the but one of the buttons this one here to actually turn around like change Change songs and also jazz The the Qt Pi is actually talking Jason of a serial to the the the pi zero And then that's been used with so cat to send to the actual MPV music player, which I'm just like it worked And I had it was like only like a day or two before the birthday. So like fine. We're running with that. Good enough Okay, well nice project it's always nice to have something handmade and also some really cool-looking headphones. Yeah, happy birthday One of the cool things about making your music player is If you didn't have to suffer through all this, you don't know how bad it is But just like dragging and dropping the 10 songs you want to listen to it's not possible anymore It's really not you have to go through so many hoops And you have to like it's on Spotify and then now you get your year-end list and then there's another thing There's nothing you have to go throughout the music. There's not really your music By the way, it's gone You got a new computer that doesn't work anymore What's nice is to be able to use, you know, you're a music player just drop it in there and do whatever you want with it Actually had a fun bug with this so when I was developing this these were obviously in the box ready for the birthday So I had a very small little USB to audio headphone adapter Like a tiny little duck just with a cheap little headphones like that doesn't work Yeah, and it worked fine. Of course day comes along I plug in you know these great big things with like LED lights and also a jazz and jack cat is and of course They don't work Because when it first comes on when it's powering up the powers these up when it powers up the USB system in the Raspberry Pi And it seems to bulk it on the first one I'm assuming because I there's a batch of captain here or something that's charged up. So more capacitors have been added Which cross fingers? Good That's very cool. Well, happy birthday. Once again, you got a really cool music player headphones And Keith if you want to it looks the player looks really cool if you want to document it You can put it on, you know, we have our new playground playground system on learn learn data fruit calm You can go to playground and then other people could build this as well Yeah, you can publish whatever you got. I think you know, I know a lot of people like to build their music players It would be great to share. I'm sure if you want to ask us, how do I build my own? Yeah, again? Happy birthday. Many happy returns Another Ada, that's right. We need to keep we need more. Thank you Speaking of music Liz what you got going on with these bops So over the break I worked on a personal project I recently got a used keystep pro and it has all these gates out the back and Which is great, but then for patching it's tricky because it's not really ergonomical So I designed up these little PCBs that you can see above me and it just has a jack LED to show when a signal is coming through and then three wiring points so that I could wire a Jack out from it and then plug it permanently into the back of the key steps over Thanksgiving break I soldered these up mounted them to piece of acrylic and then to 3d printed mounts. They're on the side of my Eurorack stand and then right at all the cables key step and I'll press play on the key step And you can see what's going you get the lights and they're pink LEDs too Yeah So I'll I'll I'll publish the files, but it's just like a really little PCB and by doing that to have kept the cost down a bunch And it's just passing through the the signal and so then I can just patch like it's a part of the rack Yeah, it's a Christmas tree. Yes Yeah, since our almost more about the LEDs and the sound to get out It's always good to have a you know, like a long weekend because you can they get cut off all the projects that you want You want to work on anyways, it looks beautiful. Thank you. Thanks, and I was glad I could patch it on to my existing rack too What is it? What is like the first Liz track dropping? I have a couple posts up. I don't really publicize it a lot, but Right folks, you can if you can figure out where to find it apparently there's some tunes This has been a ghost writer for Taylor Swift. That's a big secret. Okay. All right. Thanks much less No, what is going on? Hey, what's up folks? So this week we have a 3d printed space clock. This is a collab project with Liz so it's a circuit Python project and It's got earth time right here in this analog kind of style. Okay, this is the four inch display But what happens face what if you're in space? You maybe want to see what the time is in Mars So we have a button on the back press the button and it switches to Mars those are fit map images and listed a great job on changing Converting earth time to Mars time, which is the whole thing. She has a playground post about it and What's what are they or how does it how does it work? Do you know? Um, so there is an algorithm That was published by NASA. Yeah, and Liz used chat GPT-4 to kind of convert that algorithm into CPython. Okay, and then she used Jep Jeff's decimal library in circuit Python to Make it more accurate because there's apparently a lot of decimals that have to be Used because she kind of hit some limitations in circuit Python to do floats so it has a NASA quality it is the NASA Quality space time so it's amazing. Yeah, this is like one of the nicest prints. This is really good. Thank you It's Yeah, all the board on the back there arcade button and it's not fits and everything it looks great But yeah, we have we have a learn guide that has all the details Files and everything it's all open source, of course And it just sits nicely on your desk. Let's go back to earth time the hour and the Numbers are all generated with the font and it's all vector IO. So it's very nice in terms of like the refresh rate So that's really nice Yeah, so folks can have at it. Maybe add moon time if that's the thing or Or maybe a different planet other than Mars Yeah, yeah each moon and each planet has a different rotation and it's you know like one day on Jupiter is different than one day on you know, you could do a lot of neat conversions a fun project Then you get to put the art on the round screen. So I want to totally send this to add a friend who worked on like one of the Mars Okay, she actually had we had to sleep on Mars time Because she had a shift where Mars related not earth related So this would have been really handy for I'm gonna send it to her. Maybe she'll Cool. Yeah for sure. Yeah, uh, so yeah, check out the learn guide in the video. It's all it's all out there Yeah for for advanced, uh projects you could do something like interstellar And you could say like well, how many years have gone by? How many years have gone by on other this other planet that's you know, so far away That oh, you mean like make a clock where you like you'd say how fast you like how many Like fractions of sea are you going and I like it'll speed up the time. Yeah, it's traveling really fast So you're if you're on like a spacecraft that's going really fast, you'll know what year it is Wow. Yep. Good times All right. Thanks. Yeah. No problem. It's a big big problems. We have yeah, I think about a lot All right, gp. What's your go on? Hey, I've got some led things going on. Uh, I want to Show you two of them. So I just published this guide on adding tiny little leds to your lego builds to your lego models And there's kind of two speeds. One is the real easy speed, which is this one this uses a little Cell little uh, what's the word coin cell a little coin cell breakout that we have there No soldering just twisted a bunch of the wires for these smd pre-wired leds and fed them through This razor crest star wars razor crest shift to add some little headlights a little Cockpit light for baby yoda there and a couple of blue lights for the engine So this is one way you can light up a model really really easily But i'm going to add a camera view here real quick, which will show you How we're doing a more advanced version using circuit pythons. So let me Add a window real quick here. It comes cool is the the ilm folks used adafruit neopixel rings for the Oh, that's right itself Yeah, so it's like you're it's it's um It's good for the lego and good for the for the production models. Yeah, these are great for for any kind of uh small models So this uh is an example here of using a little cutie pie running circuit python. We have our aw 95 23 um led driver and gp i o board this thing is running over i square c And it has uh 16 channels. I've just got five leds plugged into it And this was the first project where I really grasped how excellent async i o is allows you to do things Asynchronously so you can see here. I've got an led that's kind of flashing really slowly the right the right uh Move this out of the way plate here round plate and to the left is one that's kind of flickering more Uh, and there's one that's also just kind of coming on steady and turning off So these are all running at different rates And I was able to do things like patterns for my christmas lighting uh winter village that look like Lights over your window versus a little kerosene lamp versus some steady lights And these are all done by making little functions Which you can then have async i o take care of all of the sort of parallelism of it Which is uh, so nice. I'm so happy about this. Uh, it's perfect I think for this type of project where you know, oh, I want this thing ruined slowly I want this going fast and I don't want them to have to all know about each other So async i o made it really easy for me to use these little leds for uh for that winter village lighting All right, very cool. And we'll be playing I think one of your videos top of the show on ask an engineer and then you have um Also your show tomorrow. That's right. Yeah, come on by tomorrow for mortian anagans. All right. Thanks so much jimmy. Thanks All right next up is brent. Hey brent and for brent get started hug report We do hug reports at aida for just a bug reports hug report to brent has been yeah hug report brent Because you're on the show. I get to say hi um and uh for folks who love using aida for dayo whipper snapper and um Want to uh See some of the or you want to see one of the people behind the scenes Uh, not really behind the scenes or you're you're in the scene Um brent is one of the the folks that has been pushing all the excellent code Working in the community and getting all these things. Uh talking and publishing on aida fruit.io So thank you so much brent. Yeah, lots of folks lots of folks use What's coming out of your brain for all sorts of i o projects every single day. It's cool to see Here's next year. Yeah. Um, what you get going on? So Everybody has beautiful projects. Um, I have more of a hack. So if you go to ikea, they sell this Oh, no, it's reversed Um, they sell this sensor called like Well, you could try it fill if you really want to try pronouncing it, but it's like the venture And it's $15 and it's this air quality sensor. Yeah, and it's really cool It has this little bar on the front and it's designed by david wall and It's really like a very nice industrial design has nicely Everything and you can look at your quality at a glance and It's part of what we wanted to do with whipper snapper, which is aida fruit.io Is no code solution for two years, but we haven't been able to do it Because it wasn't ready. Like we didn't have the components in whipper snapper require To do anything with this little sensor. So I won't plug it inside of the sensor. Um There's a qt pie sp 32 S2 And a bme to 80 facing outward so it can get like some of the airflow from the preparations on the back And it's sorted up to Um, the test points of the pads on this pcb And the qt pie itself is running, um, the whipper snapper firmware And it sends data both from the bme to 80 so temperature humidity And it's also, um, the air quality from this PS PM 1006 Air quality sensor, so Over the past few weeks. I, um Modified the aida fruit air quality library which works with All of our air quality sensors to also work with this akea sensor Um, so it's not exclusively for whipper snapper. You could use it for Anything you want to use an arduino or something like that And, um, it works as well with whipper snappers. So I'll show My, um screens. You can see what I'm talking about. Yeah, so there's the board. It's currently offline because I unplug it for power and, um It's running this new alpha for whipper snapper And, uh, there's the humidity sensor. There's a pressure sensor. There's a temperature sensor And there's this akea sensor And we have this beautiful new like component picker that born, uh, my colleague has worked on And you can search akea and the sensors right there and we can't add it because we already have it You can only do one board twice at a time But if you work to add it You just select how often you want to send data to io And that's it. Like that's all that's required for setting up a project. It's online now Yeah, now it's fully online sending data to And that looks yeah about right. It's it's 75 degrees the toasty um 47 yeah, that's correct. It's toasty in the office All right. Well, it looks it looks good. Yeah, we when we were chatting today make it look a little bit too easy It's like it's done. It's working Yeah, we're chatting today about maybe brent will work on or you know With me or with liz to make a custom pcb that goes in the sensor so that it's not even soldering required You just screw in this new board And you you know, you go to the whipersnapper page you get it running and it's like now at a fully iot um Yeah, you know a nice beautiful case and you know, it'll look just like the original ikea sensor But it'll have wi-fi support Yeah, it'll be great like especially for the fact you provide this off the shelf It's inexpensive relatively speaking like the purple air sensors like 200 dollars. Yeah, you can really do something similar with Yeah Yeah, that can be kind of cool. So we'll we'll work on that. Well, i'm distracting brent um while lauren on the Blockly editor Yeah, okay. Good work. I know this is a lot. There's a lot of things that have to happen for this to uh come true But it looks good Yeah What a fantastic Group of projects people could do just by looking at the stuff You know, doesn't that be informative for a lot of the stuff just happens to be there You can make a music player you can make music You can make a clock from mars to put lights on legas and then you can have a no-code nearly instant um air quality sensor In a matter of seconds that just uh publishes right away Yeah to clarify someone in the chat. Liz. Um, who was just on did this project for us originally Like a month or two ago This version is a like remix of this project and it uses the bme 280 In addition to the air quality sensor and it uses whipper snapper instead of circuit pipe So if you want a program you can follow this guide if you don't want to figure out you can follow my guide This is cool. All right, brent Thank you so much and thank you for all of your work helping people get things online. You're making it too easy What do you need? Yeah. Yeah. All right. Thanks so much, right? All right. Thank you, brent Okay, that's our show until for tonight. Thank you so much everybody. This is fantastic show until lots of cool projects this week Um, we'll see everybody. People can't see but jp is doing a little dance. We can see a little dance Um, we'll see everybody next week some 30 p.m. Eastern time every single week You can show and share your projects. You can bring richer stuff. Cool things you made you want to share See everybody next week. So good to see you Ask an engineer starts in just a few minutes. Bye everybody. Bye
