 Hey what's up folks, I'll go back to another 3D Hangouts. My name is Noel Ruiz. I'm a designer here at Adafruit. Joining me every week is my brother Pedro. What's going on everybody? I'm Pedro. I'm Creative Tech here at Adafruit. Every week we're here to share 3D printed projects featuring electronics from Adafruit. That's right. This is where we combine 3D printing and DIY electronics to make inspirational projects. Hello everybody. Hangout in the Discord chat room. If you'd like to join us during the show, you can join the Discord chat room. We're hanging out in the live broadcast chat channel, I believe that's what it's called. And to get access to that, you can go to discord.gg slash Adafruit and join the many folks that have been a part of the community now for a good minute. That's right. We're hanging out on the Twitch channel as well as the Facebook, actually no, Facebook cannot tonight. Didn't go? Are you serious? On Periscope and on LinkedIn. Facebook. I even updated the stream key. It's supposedly connecting, but oh well, head on over to YouTube. We've been trying to get on Facebook for a month. Anywho, welcome everybody in the chat room. We wore out last week on vacation and we're back now and we have a little surprise. We are celebrating our nine years with Adafruit. That's almost a decade. This is the longest we've ever been at a company. This is awesome. Obviously, we love our job, so we'll continue doing this for the next 10 decades and beyond. Yay. We didn't have time to update our banner, so it just slaps up together because this is last year's banner. If you could tell, it's a number eight behind the nine and maybe we'll do that next year because we're busy with the projects and we have time to like celebrate. We'll have some cake. We'll have some cake, yeah. Let's go through shout outs after we do the housekeeping. Does that sound good? Let's go to Adafruit.com slash free. You'll see all the freebies available. We've got some new stuff. Notably, the Circuit Playground Blue Fruit. Let's take a look at the texture. If your order is $99 more, you're going to get a free half size from a proto. If your order is $149 or more, you get that half size from proto plus a KB2040. That's that lovely keyboard driver for making keyboards. If your order is $200 or more, you get the KB2040. The half size from a proto plus ground shipping, UPS ground shipping is free for continental US only. And then if your order is $299 or more, you'll get that free UPS ground shipping, the KB2040, the half size from a proto and a Circuit Playground Blue Fruit. All of this gets automatically added to your cart, so that's really nice. No special coupons needed. Just go to Adafruit.com slash free for more details and more. That is some really good freebies. Yeah. If you are in the market for a job, head on over to jobs.adafruit.com and take a look at all the listings. If you are in the market for a gig or if you are looking for someone to help you with your project, you can post it up. That's jobs.adafruit.com. I see a new one here. It says create an MP3 player. Hey. How funny. Huh. We might have something for work. You just did that. I know. Yeah. So that's awesome. So that's the jobs board. Checking out the newsletters once a week, you can subscribe to the weekly newsletter that's mostly focused on products that are added to the Adafruit shop. So you can go to adafruit.com slash newsletter and subscribe to that. You can also get daily content, daily stories and shareings. Adafruitdaily.com and subscribe to the many categories. Recently we reached a milestone with the Python on microcontrollers newsletter. Let's do 200th issue. We're on 201 now, I believe. Maybe 202 because I've been out for a week. Check out the circuit python show podcast hosted by Paul Kotler. Checking it out every week. You can subscribe to it using your favorite podcasting service like Spotify or Apple's podcast. And that's kind of, that's kind of it for the shop, for the housekeeping. I got this kind of weird setup here that's throwing me off, but we have some demos where we're going to use Adafruit IO and kind of this bird. So that's why I haven't set up this way. So it's kind of this three up display thing. So we'll get through that in a minute. I forgot to go to the Discord chat and say hello to everybody. And you give some shout outs to... Liz Clark hanging out. Hello, good morning. Paul Kotler is hanging out. Hello. Andy Callaway. Do Wester. Ophia. Hello. Welcome to the show. Mike P. Yeah, all the usuals are here. DJ Devin as well, hanging out. Thank you for the lovely gifts. The nine year gift from Andy Callaway. It's very fun. We're nine year olds. Cool. I don't know if that gift is playing, but it's playing here. Maybe it stops when I switch tabs. Shall we begin? Yeah, it's sick this week. It was kind of a... We should probably make a video about our CAD part on GitHub. So that was this week. We figured that we'd make a guide on how to use the GitHub repo, whether you want to browse, download, or just know that it's available in there. We needed to have a learn guide. The GitHub repo is probably, I don't know, four or five years old now, which is... It sounds kind of young to me. Yeah, it's kind of young, but it's been there for a minute. You can head over to gethub.com slash Adafruit slash Adafruit underscore CAD underscore parts. We can search for it in Google. Maybe we'll make a quick URL for it, because that'd be nice. But yeah, there's a lot of parts. I don't know how many. There's a ton. The way it works is the product ID is the first thing. If you want to find the feather M4, for example, you can either search for the product ID or you can do a control or command F and say something like M4, which is right here. These are all the M4 expresses. We have quite a few of them. And inside the folder, you can see that we have the Fusion 360 file. If you're using that or step dot step file, dot step is a great open format for CAD solid modeling applications. I've been playing around with FreeCAD. FreeCAD has great support for step files. And that's a free solution. It's a good alternative if you don't want to use Fusion 360. And then, of course, STL. Funny thing about the STLs, Gethub has a nice STL viewer, so you can always click on an STL and preview it. They have this little kind of viewer here. You can change up the type of rendering in the viewer, which is kind of nice. You can get a good look at it. And you can download it right here if you need to. So you can download it that way. We also have a GIF or a JPEG, as well if folks want to just get a look at it. This kind of includes the silkscreen and some of the traces and things like that, which is really over the top. But it's sort of a free thing that we get because the way we generate these is literally we take Lamar's Eagle CAD design and click a button that says Convert to 3D Model and that brings it into Fusion 360 and then I manually map all of the components such as the USB connectors, the JST connectors, resistors, and all the onboard IC chips. Yeah, I have a layer-by-layer tutorial if folks want to learn how to do that process. Fusion 360 and Eagle are still free. So you can give that a shot if you want to try to make some parts that we haven't made yet. If you don't find what you're looking for, you can go to the Issues tab and create a Parts Request. So that's totally okay to do. And then I want to give a shout out to everybody who's been contributing creating pull requests. And if you have not used GitHub before in your little wary of doing a pull request, we have it heavily documented in our Learn Guide. So now over to the Learn Guide. You can search for it. Or you can see it's part of the new Learn Guides that were published this week. Excuse me, the overview here just kind of walks you through what the cat parts is. And we also have some more deep dives into using GitHub, like an introduction to GitHub or contributing to the Circuit Python repo on GitHub. We have dedicated guides for that. But mine really is focused on how do I use the desktop app, the GUI interface, so you don't have to do any terminal stuff. It's really, really simplified. So the usage page just walks you through how to use it, kind of just how I showed you guys now. How to browse through it, naming convention, what type of formats you'll find and how to do the Parts Request. So all that's there documented and there's a link to it there. The contributing really sets you up from zero to finish. So creating, first of all, download the GitHub desktop app. I cannot recommend it enough. If you're new to GitHub, consider using the GitHub desktop app and not worrying about commands because it's really easy and user-friendly to use an actual desktop app that has buttons and things. Yeah, I saw Brent post that. The latest, I think, the Ventura macOS update deleted some of the Git commands. You have to manually reinstall those. So this would probably help out with that. Sure, yeah. So once you download the desktop app, you'll want to create your login. You'll want to clone the repo. So just walk you through which tabs to click on. You want to go to the URL tab and you're cloning the repo. And what you're basically doing is you're downloading the entire subset of Parts onto your local drive. If you want to contribute, that's kind of how the way it has to be. If you're worried about file size, consider that, but I don't think it's more than a gigabyte or anything like that. I think it's under a gigabyte, but we'll see. You want to create a branch. So we show you how to create a branch, how to add your files. One note, unfortunately, with the macOS operating system, it tends to make these hidden files called .ds-store files. So you just want to uncheck those when you are submitting your parts. So I have here in the screenshot, it shows you how I'm checking only the STL, the step in the JPEG. That's kind of what we prefer, but it's okay if you have only a step file or only an STL, that's okay. But we encourage both file formats just because the step file is kind of like the OG source of your CAD part. So we really like that. And then you can add a GIF or not. I actually started adding GIFs to the community submitted parts, which I'll go through in a minute here. Once you've got your parts added, you want to commit it to your branch. And then you want to fork. You want to fork the repository. And then from there, you can go to the website and click on the button. This is compare and pull request. And then from here, you'll be able to open a PR, type in a title in the description of your PR. Whether you have multiple files or not, it all can be in one or you can do separate ones if you'd like. And then when you commit it, I get notified or anyone on the team that is a moderator will be notified when the PR is there and give us a moment to kind of review the PRs. I had some PRs that were standing out for a year. That's because it's just, you know, it was, I didn't know about it. So we're on top of it now. And if anybody adds a PR, we'll try to be on it within the week. And then on our side, when we commit it, you can always check back and see, hopefully you get notified when the thing is merged, when your PR is merged, it'll give you a nice comment. And your parts that are contributed will always be tied to your username. So we'll always know who committed what, which is the whole point of GitHub. So that's really cool. But that's a slimmed down version of how to kind of contribute to the GitHub repo. So over on the GitHub repo, we can see here the PRs that are open. And we only have one open right now. I've closed a bunch of them. I've closed about 18 of them. You can go to the commits here and see all the different commits. Pedro added the Max 17 048, which is that new battery monitor, Stema breakout, which is really cool. We can take a look at that. And then I've added some other things here from folks, which we'll take a look at. But yeah, this is a great way to kind of come, everything is tracked here. So you can always see the history of how parts were added. Yeah, I kind of just ran through it. But let's hop on over to Fusion 16 and give some shout outs here. Well, first, let me load the kind of PR that was closed. I'm just going to show an example. I don't see the arc. There it is, the arcade button, which was added by Ari Herzig. I was going to say think of your user because I'm used to saying that. GitHub user, Ari Herzig, posted up their parts. This is the arcade buttons that are 30 millimeter diameter, product ID 471, which why not just open, you know, the actual thing and go to that. I love this arcade button and it's removable. You can take the switch out. It has a dome cap that you can either put an LED in there or you can add vinyl decals and stuff. They come in different translucent colors. But take a look at the model here in Fusion 360. This is a fantastic model by Ari and they did an awesome job here. This is the Fusion 365. So you can see exactly how they put this together and it's accurate and very detailed. That's very cool. It's a lot of work to put it into this part. It's fantastic. I like the way the timeline looks. I try to keep my timeline to one scroll or no scroll bar. It shows up combining jobs into one thing. Yeah, fantastic. Which means no moves. Don't move stuff. Also added was a USB panel plug. It doesn't have to be super detailed. All you really need is mounting holes and some sort of, you know, a lot of the times we'll do parts like this that need too much detail that just a bit. I'll project the sketch on it and grab just the holes. Copy that, paste it into what I'm working on because I don't need the, especially when you're working on a big project, you don't need all that geometry bogging down. So whether you want to go that route or simple route, we really appreciate these folks adding these parts. And then here's the part Pedro added. This was generated with Eagle CAD using the Fusion 360 kind of thing that's built into it now. Just a quick note here. DJ Devon is saying that the free version does not support libraries. So keep that in mind. I'm not using libraries here. So that's good. This is using kind of the traditional PCB component. Using a library doesn't allow you to manually map components. So in these versions, you can always come here, edit the PCB component and go to right click and replace component body. And then from here, you can add any step file. A lot of the times, chip manufacturers will have a step file available to download. That's how I was able to get most of the things. And then you could also generate a part. I don't know if that's free. Maybe it's not. Maybe that's what you're talking about. There's a part generator in Fusion where you can generate parts. But if you don't, you can go to library.io and that's, I believe that's free. You can try that. Library.io is a separate part. It's kind of like they took the tools from Fusion 360's part generator and they kind of made it its own web thing. So you can go to library.io. Let me see if that's even still there. I'm pretty sure it is. Every now and then, I'll check out library.io. And it's, yeah. Data sheet to model in seconds. So it's like literally a great tool if you want to make a generic kind of part. It has the great tools for making different footprints such as DFN, QFN, the resistor packs, and some of the other, what is this? SOIC and SOP. Yeah. So check out library.io. Sign in and see if it's something that you want to do. They also have, you can also search for parts that are already kind of pre-designed. So here's an example of that. And yeah. I think that works right out. The golden nugget here for DJ Devin. Yeah, definitely. Check out library.io.io. And you can make some models. It's off the model we go. Yeah, DFN. Do I have any DFNs? Yeah, they have some DFNs. And you can generate your own using their kind of builder once you sign in. You get a nice little panel where you can choose what footprint you want. So that's kind of a breakdown of CAD parts, how we make them, how you can make them. These are available now. So if you are using this battery monitor in your designs, you can create a custom mount. It's got all the things there. And there's some other things too, like displays and things that we've recently added. So let me check those out. We have a lot of the hero, kind of hero. Kind of the flagship products like PyPortal, the Grand Central, all of the feathers, lots of neopixel rings. They're all there in the GitHub repo. I'm trying to open this here. Just to give you an idea of some of the main boards. The bitsies, the cutie pies, the circle playgrounds, the rings, the IoT displays, like the PyPortal, this is the planked version. You can see they have, you know, the micro SD card. All of these are like models that are available on various sites. It's like GrabCAD, I think has a bunch of connectors and things, but also paces like DigiKey and they'll link out to DGA and some of the other places to get parts. They offer CAD models. NeoKey is right here. While you're on the NeoKey's, DJ Devin is requesting the step switches. Yeah, I gotta make one. I think maybe Todd Bot might have the 3D modeled. You should always check out Todd Bot's GitHub repo. Maybe pull it out. Or if Todd Bot wants to contribute to the repo, he totally can. But I might, when I get to the project, if nobody's added it to the repo yet, I'll add it myself to the repo. That's normally what I do. I kinda do it per need, per need basis. I need to know basis, something like that. I don't know. Need to use. Yeah, need to use basis. That's when I actually start making parts. But a lot of times, like when I have free time, I'll generate some parts that are under the parts request in the issues tab. So, a lot of CAD parts. I mean, nine years. Yeah, yeah. We started out just kind of manually designed. Oh, yeah, yeah. We're just making it from scratch. Measure, oh. My bird has died. Yeah. That'll make sense in a little bit. Yeah, so here's an example of our recent project collab with John Park. It's an MP3 player. We have quite a bit of models here. We have the rotary encoder. We have the one by four QT NeoKey. We have the feather wing doubler. We have the feather M4 express. We have this lovely SPI TFT display. It's a 2.0 inch. And we even have a little SD card here just to kind of give us an idea of where that's going to be. And we also have these like, these jacks that we stock in the store. These audio jacks are really nice. And then a little slide switch holder here. So if you're making something like this, this is a good example of like, you know, using the parts from the repo to design a case. And here's what it looks like with the whole thing there. Yeah, I didn't quite model the key caps, but you could do that. She'd like. And that's just a little taste of that. Let's go to Discord, shall we? See if anybody's saying questions. Any questions about CAD stuff? Yeah, let's see. Liz says, yeah, probably want to be able to design the enclosures for projects without this repo. Yeah. It is definitely a speed boost to get through the tolerances and the clearances. Yeah. One of the most important things. A lot of times you just want a bracket or a plate, a mounting plate. Having the model right there is like so great. You don't have to look at dimensions a lot of the times, which is really nice. And some ups for the new magnetic USB connectors. Yeah, those were added by contributors, which is awesome. I need to probably take photos of them. I'm not sure if I have yet. Let me see where they would be under the closed PRs. That's funny, like as I was documenting, I hadn't really done a contribution from a user side, so it was interesting to learn it. Yeah, shout out to 560. I shouted them out a couple of weeks ago. I've seen them in the chat, yeah. Yeah, Eric Hess. Let's make things, yeah. That's a great thing. Yeah, Eric Hess did a great job doing a bunch of these. Notably, I want these right here, these three pins, because I think they'd be great for new pixels. So they did a fantastic job adding all the parts. So let me... It's 5360, so let's go to the list. 5360. And there are the magnet connectors. Nice. And here are all the possible things you'd want. Let's do an STL, because it has a built-in viewer, so I can just see it here. But remember opening it in Fusion, you're like, wow, this is super detailed. And all of the materials were colored and everything, all the solid bodies were colored. That's cool, so check these out. For your embedded projects, I think these would be great for folks that do wearables, like Debra, or Charlin, I can imagine them using these magnetic connectors. This is really cool art. So a PNG, what it looks like. That fantastic render. It's all rendered out of Fusion. Looks great. Yeah, so check them out. Super cool. Yes, Macintosh Librarian says, perfect for mounting brackets and such. Yeah. And then Liz says, projecting mounting hold dimensions for days. Yeah, that's what's up. Cool, I'm finally glad it happened. We've just got enough emails from the MarnPT, we're like, hey, where's the, you know, users asking about CAD parts or asking to contribute CAD parts. So it's like, all right, it's time to make a guide, it's time to do a video. Yeah, I mean we talk about it every single week, but not everybody has the chance to check it out. So this is a nice way to alert the rest of the people that it's been up for weeks and how to contribute to them and how to use it. Yeah, it's kind of like a weekly segment. It's like, all right, here's the new parts on GitHub. What do we have this week? We've got some Stemo sensors and some displays. So each week we'll come on and update folks on what new parts have been added or what things are out there. Let's see, check out the comments. Did you have anything to say? Oh, they were talking about the USB C and B tips that were added this morning. The magnetic ones? Yeah. Yeah, this could be nice. All right, cool. And that is this week's project or highlight on how to. Yeah. So let's take a sneak peek at next week's project. Oh, real quick. The guide needs a link to the actual GitHub CAD parts. Is that not linked? I mean, maybe it doesn't look like it's linked. If you go to the guide it's this button. Wait, it's not that one. It's under usage right here. It's the screen button. But it should also, I guess, be there too. I would put it right underneath the video. Right in the overview. Bam. I'll do that while you're presenting. Let's go ahead and look at this week's what are we prototyping? Do we have a screenshot up? Well, I'm editing the thing. Yeah, you're up here. So, okay. Now I was going to say where's this as your way to kind of, because I do want to add the link right now. So, this is a okay, so do that again. This week's what are you prototyping? Lamar saw this really cool Kickstarter, which a lot of ideas for remakes comes from there. And what this is, is a CO2 indicator. So, we have a cute little bird that'll act as your indicator. So, everybody's familiar with the canary in the coal mine back in the day. When people were mining coal mines, if the CO2 levels got too high or the carbon dioxide or monoxide they would have a little bird in there. And if it died they would know the levels were too high. What an awful way to do like indication. But I guess it's pretty analog, right? So, what this does is we're using the SCD-41 to check out how high the CO2 levels are. And using the brand new servo functionality inside of Whippersnapper, we're able to have the servo react to CO2 levels. So, when it gets too high the bird will die. It'll like rotate to a certain degree and then just die on it. When the CO2 levels are a nice comfortable level, it'll rise back up. It should have made it a phoenix, huh? So, it'll rise back up from the dead after the CO2 levels get back. But once it reaches I think it's, I have it set up to over a thousand parts per million, I think is what it is. Kind of show folks the that's what'll happen. It'll just die on you. It'll like it looks like it's plugging its nose depending on what angle it is, but you can have it go all the way up and it is alive again. And what we're using here is some nice little hinges. Let me grab this one. So, using using that one technique where you just burn to create a little rivet on the other side to make a nice little, there's like little hinge not hinge, rotating those feathers on there. So, to hold servo horn, it's three different parts. We're just printing this out for the bird here. And on the inside unplug this guy. So, on the inside snap fit case, of course it is mounted to a little cutie pie 32 Pico. And on the back here with a little micro server. Servo Servo. And everything is just screwed together. So, took a little bit of time of figuring out how to combine all these different pieces but everything connects like that. We have a nice little editable circuit that you can for prototyping purposes, you can use the headers. Yeah, use the headers for it. It can be in this. Yeah, yeah, yeah. Usually I don't like doing this because I want it to be as small as possible but for something that's going to hang on the wall, you kind of want it to be have a the size you want that to be a little bit bigger. You have some openings for a USB cable and the actual sensor part on the B41. And on the back here you just have a thing to like a wall hanger. So a nice simple little circuit that I find funny is that using all the whipper snapper smarts and the components we all have stemma as well. So you don't have to solder every single little thing. You're able to recreate kick starters in a week. Which I'm pretty sure it's going to last longer. I don't know what if they're going to have a server or whatever and tie this all with a subscription or what not. So it's super cool that you're able to use I.O. You have the privacy thing on there and not going to use your data for any of that. Yeah, so we set it up in whipper snapper. This is again a very new addition to whipper snapper is the ability to connect servos to your IOT projects. Came out last week. So go ahead and plug it in. You'll know right away that your device is offline because it says it is. And here it is set up as a generic servo. The way we add it is by clicking on the new component button and you'll notice down here we have servo components. We might have continuous servos and maybe steppers and stuff. But for now we got the generic servo. So let me add it. Once it goes online more components go online I've noticed. Oh interesting. So there is like an if offline don't show all the whole list. You have the options to change this servo pin connected to your Qtify. In this case it's A0. Frequency you want to leave that by default. You can change that. I remember overhearing Lamar saying that some servos might need different frequencies. So just check your data sheet if you have something from someone else. And you have minimum and maximum pulse widths. So you can change this if you'd like. We probably need a converter for that. The pulse width is the like the angle of the servo. Like how much it's rotating. Yeah it's a little weird. Like what is this? It needs microseconds or something. Go back to the components. Just want to highlight one. New addition. No, no, no. In the add components. Now that it's online you can see No, no, no, no, no. Yeah, there you go. Oh you want me to click on the button. It doesn't matter. It's the same thing. Sorry. If you scroll down you can see the I squared C components, the rest of them and then oh no what happened to the one I wanted to talk about. There it is. What I'm so happy about is It's still beta. Yeah again it depends if it's the Stemma Soil Sensor. Yeah of course. It's making me so happy because I'm able to see exactly instead of you sticking my finger inside the freaking soil I don't get dirty finger anymore. I can see what the capacity for all sort of planter projects. One of the things I want to do with this is using the Stemma Hub. Connect multiple of these up. So I'm just using one of the QDPIs instead of having each individual Soil Sensor be its own microcontroller. Cool. I got a lot of gifts to make. Some of these are gifts, some of them aren't. So I'm seeing some make it existing, but we're working on it. We're going real fast here. So what makes the addition of the Servo component is that it can work in conjunction with your other analog ones. If you scroll up back in, scroll up. I already tested it out with the PIR Sensor, the Beam Splitter, the Read Switch. It all works perfectly so for upcoming Halloween season, it's going to be perfect for being able to see control or have it through action triggers, have like the Servo do something, drop a spider on someone, or coming up later the Neopix support. So when it senses someone it'll change red or flash or something. It'll be so cool. How do I take a look at your recipe that you have set up? Oh, so if you go into the actions, you can see what happens and it'll be either these two. That's for the PIR. CD4, one of those. So here you can see go edit. So if the CD40, you can do the drop down and you can see right there for the QT Pi32 Pico and that shows you what is connected on there. Yeah, and you have a little here to give you an indicator like, hey, this one connects to a gear or a motor. Yeah, since I have like, I think it's like six or whatever on these is a really good way to quickly add an eye glance see which one you're thinking or wanting to edit. Which dev board is tied to which project. Alright, so if the C02 sensor is reading a greater than or equal to a thousand parts per million it's going to push a message to the generic Servo with your pulse width there. So that's your angle in a sense. And then you can limit how much it's checking for that. And so for that one if it's greater than it'll straight up just die is what that is. Alright. And then go back to the actions in that last one if it's reading anything below 900 parts per million it will come back to life. And that sets it back to the Servo Ingo 500. And this is a cool way to I wish there was some way to export this as like code so you wouldn't need to be connected for these actions that happen but for now this is so cool. You always have manual control too. Inside the device page you can always manually flip on switches or in this case scrub to change the Servo Ingo. I might have to update the component so let me hit update component and then see if I can get it going. There it goes. Yeah. I had to update the component because I uh I don't know. We're disconnects real quick. We can go all the way all the way down all the way up. It's super cute with the action of the those little feathers that are going on. And you can add more values and more triggers like maybe somewhere in the middle because he's starting to go down. Yeah that is a good point. I should probably add that because there is some to the dead or alive. Cool. And then the PRI sensor here it's connected. No that's for something else. I was testing all of them. Just like wave your hand to let the bird go up or down. Liz says dead birds till no tails. Little pirates. Yeah so this will be next week's project super cute remake of who knows if that kicks everyone making or not. But you can build your own. I mean I thought it was a Google thing. No that's something else. Same thing with Google. It doesn't matter if you're a big conglomerate or a little kickstarter. Ideas are kind of out there. So if you want to make your own for a year and then shut it down. So this will guarantee that you will always have a service that will be up and just go away. Super cool. Give it a try. Servos and IoT is going to be a huge thing. It's so cool. I am going. Big shout out to Brent and Lauren and everyone else on the IoT for doing it up. Yeah they're adding some more stuff in the beta stuff and it's so exciting. Oh whoa. Is that you? It's like yes. Oh it's eating. There you go. Or it's feeding its children. Right. So what? And that's what we're prototyping this week. It's a little C02 Canary. Yes. Canaries are yellow. I thought they were red. I was like Pedro. They're all yellow bro. We're thinking of a cardinal is what you were thinking of. Yeah. Cool. Alright. Two inch bull ants in Australia. More crickets for the biggie in Florida. Yes it's true. It's all a giant stick bug in the morning. Is that always great? Yes. Spending every day. It's so freaking fun. It's definitely someone who doesn't know how to code I can see a secret power now. Yeah I can see a project like the kickstarters and be like dude we have all the components we have now all of the glue to have that come to life without having to wait on two years of some funny that's going to fall through or whatever. Yeah for sure. So that's what we're prototyping. We'll be having a video project on this next week. That is a good one there. It's more fun. They're going to build something like this with neighborhood. They're freezers holding a bunch of beers and from time to time there's a CO2 leak. It's difficult to detect. This will work perfect for that. Yes. That's great. Yeah really practical in that one. Yeah for us it's like a little you know it's basically like when there's like it's a CO2 monitor. Just giving an idea of like dangerous levels of CO2. It's simple. We have another project that's circuit python. It's the matrix portal and it tells you it has a happy face or a sad face. It's pretty much that project but this one's more physical. It's less expensive because it's just a QDPI sensor and a servo. What would I like having that whippersamper layer on top of it is that you have logging and you can see at what time CO2 levels rise up. You can share that stuff. That's very nice. You get line charts as well so you can visually see patterns if you need to see any patterns of CO2. And the SCD-41 has not just CO2, you can do the temperature and humidity. You have all that other additional info that we don't have on the matrix portal. That's a great project for all sorts of people to do. Cool. That's what we prototyping. We will launch this next week. So cool. So happy. Just with the little wings. Although one little funny thing with the wing. Dang it, I put it on backwards. It looks like he's all buff. I think he's been lifting weights. Look at his arms. I need to put a... You've been testing it so much that it's just flexing. I need to put a vinyl like a little mom tattoo on there or something. That's cool. Let's go ahead and jump into this week's Community Makes. We're still like... I want to show JP's project. A little bit beyond prototyping. The guide just went up live. You can build your own DIY MP3 player with CircuitPython. This allows you to use the microSD card slot that's a part of the display and it lets you play three files. So here I have some MP3s. It uses the rotary encoder as the volume. It's using some libraries like the progress bar to do a volume here. So I can change the volume. And then you have a progress bar for the track itself. So I have a track ID of the title. That's my pseudonym for my artist name and then that's the name of the song. You can use these buttons as controls. So this is play. You can skip, replay, play the next song. In the guide it's using the audio jack. So you can do headphones because it's more like a Walkman. But in mine I just threw on one of our mini oval speakers and I put it right here inside the case. It's a snap fit case. You can take it apart easily. It's got some nice features like the reset button here. Which is always nice to have access to. The neopixels here light up. So if I press pause you can see it turns purple. Press it again. It plays it. And then I think this is green. Oh I think I crashed it. Got some memory allocation stuff going on. But thankfully I can just hit the reset button. It's a good way to test the demo. You can also see the neopixel for status indicator shine through here which is really nice. So here it is just starting up again. That's what it starts with. It doesn't play the audio by default. I just want to hit play. And then you can change the default volume and button layout stuff all in Circa Python. I 3D printed this case in two colors. I did a color swap so that I can get a little bit of light diffusion here in the cover there. But yeah this is a really cool kind of MP3 player. It has a lot of features and a lot of opportunities to expand on it. One of those could be you can use this exact circuit for making a prop so switching through the sound effects is what this could be as well. I did a Venice and amazed by the MP3 decoder library. Such a long way. Yeah amazing. But yeah I'm using a fairly large 16 gigabyte card so you can put massive amounts of music. There are some memory things you might run into so you just gotta be careful on what you're doing. I tried to add some custom fonts but I think that was too much for the memory. So maybe you could pick a different board that has more memory, maybe an ESP board. The audio isn't going to be loud because it's literally called a small mini oval speaker. But if I wired it with the headphone jack it would have really good audio. And these are some songs that I have published on my SoundCloud. You could also go to Aetherford SoundCloud and see them there. Yeah so fantastic job by John Park putting together the code. I think also Todd Botte also helped out on it. I saw his name in the code but this is all live. Just a couple moments ago it was published. I had to rush to get the CAD files published but they're there now so folks can download STLs, the step file, the fusion file. Earlier in the show you saw this case in Fusion 360 so all the parts are there. And then I guess the battery there's a honkin 2000 milliamp battery in there. You can fit whatever you like. There's plenty of room in there for maybe a bigger battery. You can kind of see it there in the grill. A couple of screws and stuff like that but most of it snap fits. And now you can do this thing here if you'd like. We'll probably do a video to showcase JP's guide in the coming weeks because we think it's a really good project to kind of do a guide on. Well the guide is out but we want to do a video to kind of promote the guide and it's as big as a real Walkman. I went to Wikipedia and used the dimensions to kind of create the dimensions for this one. Super cool. Yeah. And then if you want to turn it off you can use the switch here. That's off. Turn on again. Again there's so many features you can add to it. Maybe you want to do battery monitoring you can add that new stem of breakout that does the battery monitoring so you can get a little indicator of the battery. That's cool. All of this is done with display IO so you can you know do different things maybe change the colors you try to do the fonts if you want to add some smarts to reduce the amount of characters so you don't run into those memory allocation issues you can do that so I hope all folks will like make a bunch of additions to the software because it's all in circuit python and it's a really quick way to kind of prototype your stuff. So cool. I think the hardest part about this is going to be what color combo will you use? Yeah. To go along with the available keys. The keys can all be different colors a lot of customization. Yeah I don't know what else to say about it but check it out. That is public. Let's take a look real quick. I'm looking for the learn guide. Here it is. Here it is. Oh we got lots of new guides. How's that? Yeah way in. It's crazy how all the guides come out all at once. Like we got the nudes guide, the list, we got the mailbox wifi notificator from catney the walk person from john park and then even jeff has one on the combo keyboard. That's cool. Hey that's the video. There just as a demo just to kind of hear. You can use the rp2040 which might be more readily available than the m4 express. We're using one of the amplifiers the i2s amplifier this one here which gives you good digital audio. All the parts and bits and stuff there's the cat files. Ah there's more screenshots what's the show's over. It walks you through installing circuit python here's the code it breaks it down to We can cover this Yeah we can cover this on the canary. Yeah you're right. But look at the the photos. They look fantastic. Nice. Look inside of it. Everything kind of snaps with these tabs. Super cool. Super cool. I think for the shoot we're going to do it at a order by Epcot. Yeah galaxy rewind dressed up as maybe we'll have a red blazer on. Star lord. I'll be Peter Quinn. Uh-huh. Where's Peter Quill? I forgot. I think it's Quill. Is it Quill or Quinn? Check out the comments. Oh Brent's in the house. Hey Brent. Congrats on the nine years. Oh yeah. I forgot. And Tyeeth yeah loves what are separate for automatic feeds for everything graphs if desired to combine actions feeds and maybe some if this then that for a great journey in near limit this possibilities yeah the only problem now is for me like what project to actually tackle make it part of that. Yeah and there are going to be some limitations but that's sort of the fun part like figuring out how to overcome the challenges and stuff so lets you kind of simplify what your idea might be. Cool we are about ten minutes away so let's do this week's time lapse alright this week continue with more skull based time lapses for upcoming holiday is what two three months long how long we celebrated. This is a planter that's kind of a remix so A. Allen posted this up on the universe as a remix the original post is just the skull but Alan thought it would be nice to make this into a planter and added some holes for drainage drain holes I took this opportunity to test out some other glow-in-the-dark filament and this stuff look at this atomic looking blue aqua blue green it's not going to show up on here obviously but I'm quite happy it's probably super abrasive because of the amount of the glow-in-the-dark powder stuff that they added to this is quite a bit like it if it was super dark in here it would light up so much and it stays like lit and it's one of those glow-in-the-dark so like it gets off a hue which is like yeah I'm super happy with this you can use it as a planter or it's probably candies for us they did add drainage holes and there is a super part that has like the tray on there so you know bottom water your plant it's a really good way to do it it does require quite a bit of supports for underneath it would have been cool if it was simplified on the bottom there and there is a bunch of detail that's super cool if your printer can get it resolved but other than that it's so detailed all these tiny little crevices and stuff that came out I'm surprised yeah let's take a look at it it's a free download on Thingiverse so again it's a remix by A. Allen or SNIT Designs posted it up here's their posting of it in the dark thanks to Motizuma for the original tray design and the original skull planter is here here's the original one by Martin Hinner posted this one up Brent likes the skull planter so I guess I'll have to use it in the stem of soul sensor I think this is a remix of a remix of a remix I love those because this is deep like I keep going back to different remixes so I guess in this one doesn't have the Carlos Campos posted up the I actually printed this one from 2014 I just went like 4 remixes deep yo if it works why not add on to it and this is a remix does it end this is why it's by all the hate words Thingiverse I love this the way that all the etch regions are all linked this way I found the original and it says I couldn't find a printable skull and Thingiverse that had a removable mandible with the teeth so I created one originally this was a sketchup model that I imported and sliced and diced and printed on my thingalmatic again this is the other reason why I like it printed all the pieces and glued together enjoy this is what the original is it's like crime scene investigating cads like what's the what's the origin of this Paul says 3 printer inception yeah boy golly we literally went 5 deep that's wild to make or not to make that's just the question to remix or not to remix so the flight demons call I think all the hate might be gone out that Thingiverse with Ultimaker but yeah this is one of the things they're the oldest so you can go far back in history on what was going on in 2013 for us anyway 2012 whenever we first started alright so there's your deep dive into skull remixes still get like the whole community I don't know who to credit it's pick exactly who I still get tips from the first thing the coral cuffs that we made so long ago it's like what? okay thanks we go deep we have some more community makes that were sent to us so let's take a look at those if I can sort it out here in the notes scroll down let's start off with this first one this is a this one is so cool Keyblade this was posted on get on Twitter by Daniel D no Cla Danielle they are a cosplayer and I believe they do stuff on twitch but look at this fantastic how freaking cool is that completely different well not different but in terms of the embellishments and like the theming of it yeah this is a cool thing so the thing in her hand is it's hard to tell but that's the Keyblade that we did a few years ago it uses the prompt maker featherwing or feather in four in a ton of neopixels but it has sound effects and all that stuff and it looks really fantastic in this in this kind of remix rebuild and it's a fantastic cosplay oof tail and everything it's crazy so shout out to Danielle for posting that up posting the original in the chat room next up we have a a make of the halloween tombstone project so this is the halloween tombstone project and this is posted up by prusa user or principals user grumpy scrambler grumpy scrambler posted this up and they say well let's take a look at the photo first looks fantastic look at the weathering they did dude this looks so good wow I can't read it actually it's in oh it's like german or something but look at that it's fantastic it's got the eye and everything they say a wonderful project for halloween the eye of the halloween m4 is great unfortunately I can't get the neopixels strip to work the m4 always goes in the boot mode immediately when transferring alright there could be the timing of putting it in the bootloader maybe yeah maybe I would suggest posting up on the forms so we can get our our customer service there's a bug in the latest yeah there's always something with that but the original one has the neopixels strip inside this kind of box and then I'm using black LED acrylic to diffuse the lights that's what it looks like with it open it's not too much of a build because a lot of it is done through you know the halloween eye and there's lots of expansion ports for neopixels and sensors and that sort of thing but yeah this is a lot of fun so if you're looking for a halloween project and you get yourself a halloween maybe 3D print a snap fit tube and stone and again shout out to grumpleys kind of but this is the first make that's been posted on it that's really cool to see alright next up we have a make of another halloween it's not it's halloween season yeah this is the make of another skull this is called the pumpkin skull you remixed this one I think I just hallowed it out yeah you hallowed it out maybe cut the top off but here Jake printed it out posted a photo and just gave it a thumbs up so that's cool looks like you can have the top be removable and that's just a very freakish but cool pumpkin you put LED's in the eyes of course you did this was from a few years ago and that was posted by Jake alright next up we have another make on proof printables this one is from luca luca posted up a make of the heat set rig if you are looking to do heat set inserts consider making a rig to make perfect, precise things I really like this design they added a clampy bit for their soldering iron so that it's easier to take it on and off I really like that it's a great idea so luca says very nice design I made some minor changes and adjustments and shout to everyone else I'm seeing lots of makes this build is becoming the most made one on printables which I like to see because it's a very useful tool alright we have a few more to go through over on Thingiverse Thingiverse user Carl FL posted up a post of the QDPI mount they say they extracted just the QDPI mount from the Neo Key keyboard the Neo Key emoji keyboard so it's useful to easily add this mount to other projects without having to recreate it that's nice I like that shout out to Carl for putting that up on Thingiverse and now we are going over to GitHub this was actually posted and featured in the python on microcontrollers newsletter this was by githubuser smk ymkct and they created a mind sweeper game on nativist pi portal and they used our 3d printed retro case that snap fits together and houses the titano we have 3 different sizes so if you have a pi portal and you want this kind of look this enclosure look for your pi portal we have them in 3 sizes so we have the titano the regular and the pint which is the smaller version pint the pint yeah I said pint how funny but yeah all of this I believe is in circuit python yes it is and it has all the fonts and yeah all the STLs as well are there too if you want to print them out but yeah mind sweeper I want to play mind sweeper now next phone game cool cool alright moving along next project is on twitter we are getting makes from all places this was posted by peter peter posted up their make of this flaming torch uses a gemma and a neopixel ring or neopixel jewel and a 5 volt DC fan so this creates this kind of flame effect with some silk fabric mesh and the fan and the gemma and the jewel I believe is the jewel all sandwiched together that fits inside of the kind of base area of the torch and it makes this cool fire effect we got inspired by the pirates of the Caribbean ride because they have similar kind of light and a fan in this fabric that makes it look like it's a fire it all snap fits together and screws together so it's really fun to see other people make it for their props so shout out to peter alright and the last one to close it out our very own paul cutler made a neon sign using the neon neopixel strips and this is all done in circuit python using the led animation library by crayola and catney ramboar we hope to do this for the nudes the illuminoodles the noodles and our leds it would be very fun to make a small version of it I think devin was asking what project we had coming up for the nudes and probably the low hanging frame a snake maybe some halloween stuff like a bat with the animation so you can see the wings going up and down it's like going between them it's like a two frame thing like traditional neon signs that would be fun for your lego set I have a week to get it already so that's probably what we've got you got like three weeks you really get two weeks and then you get one week to document that's true so you get two weeks from now and you'll have four days show it to paul thank you for posting that up on twitter for everybody to see and that is the weeks community makes thank you everybody so much for posting up your makes it's so nice to see folks I feel like the season is making it's here, it's halloween fall, the heat is slowly starting to creep away scroll up a little bit I want to highlight the I'm a snaky maker cat they made a little bit of go on twitter too oh with some of the nudes that looks so cool is it with the nudes? I thought I should maybe no it is nudes you can tell by the density oh my gosh they already did it I was going to say there are some giant alligator clips I guess it's been done you just scale it down let me see so snaky maker cat says I made some blinkies inspired, yeah you got to scale it down about a quarter of the length using the flexible filaments oh cool, dfrobot socks them as well that's fantastic looks like we got to do the bat one then to frame animation on it oh this one is cool too this is from oh I forget it's on the tip of my tongue this dragon looks awesome I think it's from tested Norman Chan did it very cool yeah and if you scroll up a little bit in the discord someone made a canary co2 monitor already check that out that's exactly it that's fantastic with the sd40 30 yeah this is a nice one too wow that was the tft on there displays shout out to vw yeah it looks so good finished a few weeks ago no fancy enclosure yet but it's got the sd30 and the esb32 s2 tft feather life drew the bird so cool this makes me happy that we're not completely ripping off the kickstarter one I don't think we need a fancy enclosure it looks great how it is I love the display right away you see what it is do you want to have a display now I mean we already have one that's cool though I like that it tells you the fair height I think that's been worked on I keep having to have a separate window in for the conversion wow it is definitely the season of making everybody is just posting fantastic makes super cool I think it's gonna be that's it for this show I'm hungry let's go eat I wasn't looking on the sorry folks I didn't switch the thing yet that's about all of it now I posted all of it check everything out on the discord it's hard for me to run a show and keep track but man this is fantastic this is my lunch I'm eating everyone's inspiration that's great well tonight we are gonna be on show and tell we invite you to come on as well it starts at 7.30pm Eastern Time will be there I think this week it's hosted by Lamar and Phil Mr. and Mrs. Lady Aida and then shortly after is Ask an Engineer with Lamar and PT Mr. and Mrs. Lady Aida again at 8pm Eastern Time shout out to Melissa for hosting last week she did a fantastic job and had some really awesome people come on and share the project so whether you have a finished project or you're just starting a project all is really fun to see we like seeing retro gear and all sorts of stuff so please come on by the way it works we'll post a link to join the stream yard stream in the discord chat room so that's how you get access to it you just gotta be a part of the discord chat room and we'll post it in the live broadcast chat channel that's gonna do it for us we'll have some tunes at the end but yeah I gotta make some screenshots for this walk person thank you everybody again we'll see you next week and don't forget to make a great day see you later tonight
