 Folks, welcome back to another 3D Hangouts. My name is Noeva Revez. I'm a designer here at Adafruit and joining me every week is my brother, Pedro. Good morning, everybody. Pedro's proud of it. The creative tech here at Adafruit, every week we're here to share 3D printed projects featuring electronics from Adafruit. That's right, that's sure. We combine 3D printing and DL electronics to make tongue twister projects. Hello, everybody. Welcome back to the show. We're super excited to be back here. We want to shout everybody out in the Discord chat room. Yeah, the Discord chat room. Pedro, shout them out while I fix the Discord chat. Good morning, everybody. Hanging out in all of the chats. As you said before, we are on discord.gg slash Adafruit. And we're giving shout-outs to everybody hanging out. We got Brent hanging out. Andy Callaway, Greg Z. We got Dew Wester, BlitzCDDIY, Liz. Hello, good morning. Riggs, Vince, Rosin over on the YouTube chats as well. We got Doug and on Facebook. Sorry, I don't have that pulled up. And on Twitch, good morning to everybody hanging out. Yeah, thank you for joining us. Back. Yes. For a little bit of a hiatus last week's show. We still got the project video and the guide out. So thank you all for your patience. Let's go ahead and jump into the show. Cool, yeah. We'll start off with a couple of housekeeping items. So we'll start off by paying some bills, shall we? For orders, let me get my bearings here. All right, so there are some freebie deals going on, as you might know. And if you want to know more about it, go to Adafruit.com slash free. I'll run through them a little bit quickly here. So for orders that are $99 or more, you'll get a free half-size perma-proto breadboard. For orders that are $149 or more, you get the perma-proto breadboard plus a randomly selected stem of QT. If you have an account with Adafruit, well, make sure you don't get the same one twice. For orders that are $200 or more, you get the randomly selected stem of QT board, the free half-size perma-proto breadboard, and free UPS ground shipping for continental US only. For orders that are $299 or more, you get the free ground shipping, the randomly selected stem of QT, the half-size perma-proto breadboard, and a circuit playground express. Awesome, all great deals. Check them out. You get as many freebies as you want. And now all supplies last. Yeah, that's great. All right, the next one is the jobs board. Help Wanted, help is indeed wanted if you are looking for some maker gigs or if you're an employer looking for some makers with maker skills, check out the jobs board from Adafruit, it's jobs.adafruit.com. There are some new ones here. We'll just kind of run through them. We got a CAD engineer for the Berkeley, California area. There is a need for an experienced electronics and LED technician for a patriotic memorial project in Nebraska. There's also a contract position opening here for object color tracking in Montreal, Canada. There's another one, there's some Circuit Python ones. Circuit Python project is a personal one in Virginia. And there's another one here. Circuit Python code are needed for an Adafruit Matrix portal. This is from Ali G's vault. That's a freelance gig. So check them out. You can make one, you can make a profile, it's free to do so. And Lamar and Phil make sure that there's no spammy business going on there. So all good things. Adafruit newsletters, they happen daily. So adafruitdaily.com is where we want to go to check out all of the different daily categories of emails, of stories, of projects from the community. So check it out, adafruitdaily.com, the standalone website. You kind of have to opt into it. You don't get automatically subscribed to any of these emails. There's a once a week product focused newsletter. It's called adafruitdaily. Go to adafruitdaily.com. Go to adafruit.com slash newsletter for this one. I don't know what you'll find at adafruitdaily.com, so. Adafruitdaily.com is where you can subscribe. Oh, we have the URL too? What? Of course we do. I thought it was just adafruit.com. So you got a hand full of newsletters you can subscribe to there. You got electronics, Python microcontrollers, make your business, new products to be printing, biohacking, wearables, things, make code, IonMPI. I literally did this back. This is the adafruitdaily. That's the one at PageSode that has all the categories. And the once a week product focused one is this one here. Because there's no text here, right? I need to, it even says right there in the little label, new news, new news. All right, well those are the newsletters. Excellent. And then that's pretty much it for the intro there. Yeah, the little intro there, housekeeping. All right, cool. And jump into last week, weeks, months project. This is the DIY quiz show control system modeled after Jeopardy. This was done by Dylan Perrata. Now let's take a look at the overhead. And here's the parts. Yeah, so we showed this off a couple of weeks now and finally released last week. We got the guide and the video out and just gonna go through the guide as quick as we can on all this. So really good for setting up trivia now that everybody can be face to face. A lot of game opportunities now are rising and this is the circuit playground, blue fruit having all these button inputs so you can see which player chimes in first. So it'll just light up to the color of whatever you set up or your little buzzer handle. All three you printed, nice little handle that Noed designed for this. This is a three part, little twisty on, completely modular so you can change out any of the panel buttons or the construction itself. Take a look on the inside of this. There's a circuit playground, blue fruit. We're using the bolt-on system. So excellent for education. If you wanna reuse this project for different, like, products. You want to reuse the parts for different projects. So all synced together, snap fit together parts. These little lids, little tabs here just snap in to each other. Nice little side of plan. Click on that and then on the bottom here we have our Stema speaker with our nice little themed grill to eat fruit. Little stars. All snap fits together as well except for the little mounts that you have to use to sort of secure everything back together. As we were saying modular so we're using the bolt-on kit as well as these jumper cables. So you can easily extend this or shorten it. Do you wanna be a little bit more closer? Yeah. And the way that it works is that the controller or the host has to clear the button. So the players can't just go ahead and chime in whenever they want. So you have to clear that and allow them to actually go in and chime. Everything's written in a circuit Python. So of course you can change all the audio files or the colors or the behavior of everything. So let's go ahead and jump into the learn guide. Yeah, so check it out. Huge shout out to Dylan Harada for spearheading the project with Lamar. They collabed together on figuring out how to make this work. Yes. Here's a list of the parts and the 3D printed files that you'll need for this. Like we were saying for again, all completely modular. So very nice way to set up a project for that. And it's surprise everything is in stock for this. Usually isn't. I don't see usually isn't. Well, I mean, it's a good problem to have. It is. Okay, cool. Well, excellent. Yeah, now all the parts are from Adafruit. So including all the little cables and even the bolt-on kit is all available through Adafruit. So that's really nice to see. Normally you have to get like all these little bits and bobs from other places, but it's nice that everything's here in the shop. That's great. You can add everything to cart. Go ahead and jump into the 3D printing page for this. I give you all of the settings you're gonna need to use for the printing. And there is a couple of bit of supports that you're gonna need for the main case. I have all those listed there. Okay. Of course, you can edit the files if you want to use a different board. It's the Fusion 360 link? Yeah. You can just download whatever file formats, STL or step or whatever. Yeah, and of course, you can use these handles for anything else, any sort of buzzer that you wanna hook up with, specifically a 16 panel mount push button. Yeah, there's a lot of variable, like 16 millimeter, 30 millimeter, 24 millimeters. There's a lot of different panel mounting buttons and it's nice to have the little top just print out a different top and then the rest of it is fine. So that was the idea behind that. Sorry. The learn guide links in here. When it's my turn, I always fall behind on posting on the link. So, we're on the learn guide. Right, scrolling down a little bit. You can see all of the settings that you need to do for setting up supports, all of my favorite support settings that make it very easy to easily remove all of those. Yeah. There are the supports part. Scroll down. Yeah, scroll down there. I was gonna open these in a new tab or? Oh yeah, you can. This is just a time lapse. Well, I'm just showing like in our, when I'm previewing the learn guide folks, I have the auto play gifts turned off just to save on processing. It should automatically play on your thing. So this shows you way more than just a single screen shot, like how the layering is supposed to be for the supports. Yeah, I think that is the main thing I'm showing here, how the supports are all set up. You have your low density. You have a smaller extrusion width and then a little bit of a Z gap just to make that very easy to remove. Yeah, there are listed, oh boy, right here, all the different support extrusion width, the density, run through it. If you haven't set up supports yet, definitely is a good reference point here. Then save it as your main profile. And then you can save it on as a profile, yeah. So I had to jump into the circuit diagram for this. Okay. Prototype this using the alligator clips. And then after that, I can jump into sort of more permanently, semi-permanently attaching these with the bolt-on kits. Or you can go ahead and solder it too. Yeah, that's how we lay it out. The only special thing here is the way that we are connecting the grounds on the arcade button, which well up you can see that that is actually the only thing I soldered. Just have those two connected to make it a little easier. Does chain all your grounds. Let's go ahead and jump into the assembly. Okay. So we're using the jumper cables here and the flat pliers to have it bent at 90 degrees. So you can easily add it to underneath of the bolts that come with the bolt-on kit. Or, I'm sorry, the nuts for the bolt-on kit. And those are just wide enough so you can attach those wide enough to attach two of them, which you're gonna have to do when you're sharing ground for all of these button connections here. So you have to do this at least two times. So a little bit of patience. You're definitely gonna have to use the third helping hands to steadily hold the CPP in place while you attach those all together. But it can be done. So I'm showing that there. You can attach two of them. Yeah, very good. And then the GIF for actually inserting the CPP inside of the case. And that new tab. Hopefully useful for having the GIF here. So you can see it just slides in and like that. Make sure your wires are, you know, not too tangled up. I did a little bit of a braid there for the controller just so I could see which one was for that. So you just wanna line up the USB port to the USB cutout on the case. It's super easy. And then the screw mounts for that are all in the free pads. All right, so you add those additional screws. Yep. And again, that is the three millimeter bolt-on kit that we have in the shop. After you secure that down on the bottom, you'll connect the stem of speaker and then align that. The stem of speaker actually has smaller mounting holes. You're gonna need the M2.5 by six millimeter long screws. And we do have a nylon kit that might work, but I totally suggest using the metal M2.5 screws for that. Yeah, that's a good tip. But here we're gonna do plastic on plastic screws, not maybe the best, definitely metal on plastic is a little bit better and more secure. And it won't strip your plastic screws. The lid snap fits on there. Of course, you can edit that if you want to have a different lid designed for the speaker. Yeah. Snap fits on there. The speaker, the wires for all the buzzers all route through the USB port cutout. All those out. And then the arcade button screws onto the lid. Cool. And then as we were saying before, we are just connecting the grounds to eliminate one of the cables. Just make it three to connect. These quick connects are really great for arcade buttons. If you've ever used them before, definitely get a pack of these, this little arcade quick connects. They're super awesome. They make it so you can make it easier to plug it into the terminals on the button. Yeah, and it works on not just the arcades, but the panel mount momentary push buttons as well. Yeah, that's great. Any of those that are compatible with that. And then setting up the player buzzers that we were showing earlier. It's just three piece design, screw it in together. And the momentary button just screws into place as well. Yeah. That's pretty much it. Nice simple design. I think you can have a classroom assemble this in a short period of time. And then reuse for any other different projects. For sure. Yeah, and it's really customizable. So you can have the microcontroller doesn't have to be in like the controller, the host's controller, it could be outside of it. So if you have something that you want to scale it up bigger and make it more like impactful, you could kind of make your own buttons if you wanted to. You could use the big 100 millimeter buttons or create your own touch pad buttons. That is a really good idea. 100 different ways to spin this type of project. So that's really fun. I want to go back to what you just said there on making like a button that could, you know, plug into like, if you step on it or something, we've made projects like that with the, I think it was the Grinch fireplace where we're making a big cardboard button that you just step on. You could easily attach that to any other button that like, you know, just has a closed pad. Captain tape, bananas, maybe the buttons or bananas or something. Lots of different ways to have that closed on you. Super fun. So yeah, we'll be playing this a lot already. Yeah, we'll be playing it a lot. Yeah, I had to trigger it. Okay. One of the other things the PLA that we're using for this is usually labeled as natural PLA. The translucent might be a little bit more too translucent and we like the way that the natural white PLA diffuses because as you can see has a nice glow instead of like a sharp contrast. Like almost see through the glow. So I like the diffused one of the natural. But of course that is up to you, whatever color you print your cases at and have like a little logo for your school or whatever game that you're playing really nice on the side there or even just vinyl cut you can wrap around. Cool, that's the assembly part. And then the code pages should shout out to Dylan for putting the code pages together. There's a little code walkthrough as well. Definitely check out the project bundle if you haven't used it yet. Instead of having to manually find the libraries all your libraries get pulled in for you. So that's really nice as well as like the little wave file with the audio files. And if we had any bit maps would be there too. So it's really nice to have the project bundle. So you just click that button there and you get all the files plus code, right? Very, very fun. Commented really nicely. And there's still screenshots to show you what your USB drive should look like, your circuit Python drive. It's got these four libraries and then a little bit of a usage here on how to use the Bluetooth. There's a little switch on there. So if you don't want the Bluetooth you just make sure that the switch is on one position. If you want to use Bluetooth to do HID USB keystrokes then you just flip the switch on the other side and you will connect to it with an iOS device or an Android device. And then you use the Bluetooth app to connect to it. I think that's one thing that we sort of glossed over. This can send HID commands to your computer. So if you have a game that you're playing on, like a computer with, you know, for anything that has USB HID support and you can change what is being pressed. So you can actually have this as a wireless controller for your game. Yeah. And then the code rock through. Dylan breaks down all the sections. So if you're relatively new to circuit Python this will give you an idea of like what all the sections are doing. So how to like enable the speaker, all the button inputs, all the, yeah, all the Bluetooth stuff is right here. And here's the audio wave file. If you want to change the file name for that you have it looping, you would do that all here. A little bit of the logic here. And then if you want to change the colors to reflect different colors, you'd want to do that here in the if statement there. And the colors are just raw RGB values using pixels.fill. But if you wanted to use the circuit Python LED animation library, you could easily integrate that and integrate some of the animations so that you can do animations instead of just solid colors. But we wanted to be a pretty kind of minimal so that's why we have these solid colors. But you can go in there and modify it so it can be super rad and have all these cool colors and different sound effects for each player. If you want to do that would be really cool. Have a different sound effect for each player. Super modular, right? So, and circuit Python makes the iteration process like doable so you can keep playing around with it and getting instant feedback. So you just glossed over a really cool part there. That's what I do. I'm a glossy fuck. For accessibility if you, you know, they're blind or something and have a different audio. A play back for the specific player. So you customize the crap out of this and shout out to Dylan for segmenting it all. I'll eat that. And that's really just the rest of the code. That's all of it. So really, really awesome job on everybody. I love working on games. It's like the best thing. And then there's the circuit diagram. If you want to get that, I kind of glossed over that but you can create your own circuit diagrams using the fritzing software. You can pay or compile it yourself and we have a library of all these parts too, right? And one of the extra bits here, this little arcade button, you can use images. Right, I think that's what we did. It's just a natural part. At some point we'll learn how to make our own fritzing parts, be in Pedro personally. Whatever. It's just a illustrator file. It is illustrator. So it is vector. It is vector, yeah. Edit that. For sure. And you can download the fritzing file. But that's it in that shell. Do we make this public? This resource page? I think it is, right? Oh. I feel like it'll let me know. It's just, yeah, there's a private button there but it's not checked. So I guess it's not private, sweet. Which is good. You should definitely let folks download that. Yeah. Cool. So yeah, that's really, really fun. Dang it. And then we glossed over the whole inspiration for this. Varvarn from Reading Rainbow and Star Trek. It's gonna be hosting at the end of July. So everybody tune in for that. So, you know, we get the ratings up on that. Hopefully stay on as a permanent host. Yeah. Definitely can't wait to see that one. My son, Gavin, loves Jeopardy. Yeah, for sure. We're all watching. Yeah. Cool. Right. Okay, so that is this week's project. What, what, what, not that one. Oh yeah, let's go ahead and jump into what are we prototyping? Which one do we do first? Okay, do we wanna check in with the discord chat room before we do this? Real quick. Say what's up. Let's see, I've been to saying, you wanna see a host, a YouTube game show. Jeopardy-esque. Will that fly legally? Let's see what I know. I would hope it'd be okay. Just call it so it melts. Just call it Jeopardy-style. Like we had to. We called it Jeopardy-like. Yeah. We might have to change our YouTube video. Because this is Jeopardy DIY. Maybe that's okay. Jeopardy DIY. I mean, we're promoting. We're always on the edge of like, is this, is this legal? All right, which one are we showing off a prototype? Yes, let's go back to prototype. Okay, cool. So we'll start off with- I don't know which one. Trinky? 2040? Okay, so Trinky 2040. Yeah, so JP was showing this off on his Pride at Pick of the Week. And this is a little absurd, but Lamarro has been showing off the Trinky board. This little guy here, without all of its craziness. It is a RP2040 in a Trinky style. So it plugs in through USB. And you can have your Stemma QT sensors stacked on there. But if you're using just the screw and the standoff, you can either limit it to just one. So I thought, oh, what if we three print something where you could just keep stacking and make a leaning tower of- Stemma. Stemma. Leaning tower of QT. Yeah, so what we did here is take the Lego style little mounts for all of your Stemma sensors and just added these little snaps so it'll grab on to the top here of your sensor, if you have a sensor. And then you can use these studs. I think I used them all up to just connect it on the top here and you just keep stacking these guys up. There's a Lego kind of brick to show that this is Lego. I don't know. I mean, you could use like a Lego board if you want to use like a pref board or something. But these will just snap in like that. And then we have, we didn't have like the stud or a tube version of this. So that's what I'll, so maybe go, oh, maybe we can just, you know, design those. Just people have options for the way they want to stack things. So yeah, you just snap in either on the inside like that or tube to stud. You just keep stacking these all until you, you know, you have as many sensors as you need. We're also using the little USB shell that we have on here. So if you want to have a more secure connection to your USB port, just snap in like that and you won't have it sort of, you know, go all crazy. If you have like a switch or something on top of there. Okay. It'd be a lot more stable. Where can folks get the, not yet? I don't think we've really seen this. Yeah, I'm gonna upload these. Yeah, I've been testing out, yeah. I had to do some adjustments to the height of the little snap thing there. Just make sure that they grab on nice and tight. But it's cool that you're all snapped. No hardware needed. That's the point. No screws needed. They'll just snap. The only thing that is needed is like super glue because these print in two different, they print split up so that you don't need any support materials for the tubes. Right. And now you get the best resolution printing that one. Oh my God, yeah. So if you're ever doing a design like that, just split it down the middle. You can print it in two pieces, just collars and glue them back together together. Pretty simple. Yep. That is the 2040 Trinkie stackable Lego big place. To go with that, we have a model for the RP2040 Trinkie. This is what it looks like. We just took the Eagle file from the Mar and turned it into the 3D model with Fusion 360. These are, if you wanna put the link, Pedro, on the GitHub repo. So the GitHub repo has this 3D model. There's my GitHub repo. So you can check that out. Super visually stunning, I know. Look at that huge visual stunning list of parts. Cool. All right. Yeah, so we got the link for the GitHub. I do, no, that's what I'm looking for. I was looking for this part actually. Yeah. So if you haven't started and you're like GitHub, you can start so you can see whenever I upload new stuff and I have some other stuff to share. But yeah, that's the RP2040 Trinkie kind of 3D model out there. Yeah, and I also made sure that the PCB is the right thickness, three millimeters. Yes, yeah. It's a little bit thicker than your normal 1.54. But in any manner, back over to what you prototyping. Kind of an early one. This is a fun little keypad. It's a four button keypad in the shape of a kitty paw. It has a display in the center. This is a collab project with Liz, party parrots. So the idea is that you can press these buttons and advance the animation. This is a spreadsheet animation. And the idea is to make this into a USB slash MIDI controller and you can kind of choose whether you want it to be a MIDI controller to play some music or a USB controller to do just some fun macros. It's powered off of the QT, the QT Pie RP2040 and the USB-C on the back there and it has snap fit parts, a little kitty in the back there. And they're all just free wired, no custom PCB. Yeah, and this is a little TFT display having the party parrot gift. So that will be next week's show that we'll talk about. Hopefully we'll have the video next week for it as well. But the learn guide for this is actually out now. So if you want to know more about it, check it out, it's live right now. But next week, we'll talk all about it. Yeah, we're out of time for this week for that. And that's, we're not done with prototyping. We've got another thing. This is the Macro Pad RP2040, just released. Very new, very awesome. Three by four button keypad with a built-in OLED display and a rotary encoder. This thing's amazing. It's got a couple of different PCBs going on and what I want to do is make a 3D printed kind of wedge so that it'd be at an angle. So this is a 14 degree angle and also ties into the built-in standoffs that are soldered into the PCB. So really cool. Just a kind of a running the demo mode right now. I don't have anything going on it, but it's really nice. You can add more sensors using the STEMMA QT connector here and then reset button right there. So that's really it for that. So we have a CAD model for it as well. So folks want to start designing cool enclosures or different projects for it. We have two different ones. This is the bare bones. It just has the PCB with the standoffs and the kale sockets, but the switches aren't there, but it does have the display and the rotary encoder. That's what the bare bones comes with. If you want the full kit, the starter kit, it comes with the back panel, back plate and a key plate that kind of helps stabilize the keys. And I also threw in some Cherry MX switches there just to show the layering of them all. And then I have some screws in the back there, the M3 screws that show how they all get screwed together and fastened. But yeah, the models are available right now on the GitHub repose, you can check those out. Yeah, and sign up to get notified if you didn't, if you weren't able to get one and you want to get one, you can sign up. They will be back. Yeah, they will be back. The one I was working on. Yep, there's a couple that are stashed away, just ready to be released at any minute now. So keep that page open, reload it several times. Right, right, yeah. But yeah, that's what's in the works right now. I'll release this at some point. So yeah, demo code. Yeah, there's some cool demos at Dan and J.P. And almost forgetting, I think Katni are working on, so stay tuned for those. That's one of the cool demos. Yes, more to come, more pause and stuff. Cool. Yeah, I think that's a good prototyping. Yeah, let's do a quick layer by layer. If I can get to that, I'm gonna do this. Go here and then here. Yeah, so if you are interested in some CAD stuff, I got about a 30 minute tutorial on how to use, how to make symmetrical designs. This kiddie paw thing, I had to learn how to use symmetry in Fusion 360, so there's a way to use the symmetry constraints with splines so that you can have really curvy shapes. So in this example here, I'm showing how I have user parameter setup so that I can change the curvature of this shape that's all built with splines and it's symmetric so when one thing gets affected, the other side gets affected and you can do symmetry four ways like this right here so the left reflects the right and the top reflects the bottom. This is supposed to be kind of like how I created the bezel for a display. So if you're trying to make like a TV, like an old school TV with like super curvature and bezels, you definitely wanna learn how to use the spline tool and even better how to drive it parametrically and symmetrically with sketch constraints. So check it out. Not a lot of people checked it out so it's one of those really niche, you didn't think you'd need it, I didn't think it. I went this far without knowing and that's kind of fun. Yeah, we did it before it was doing it inside of Illustrator which importing that in, you'll have all these like dots all over your curves. And it's like, why don't you just copy and paste the other side and it's like, well, it has to be a closed spline and I had to really massage the shape to get the proportions right for this kiddie pot. Like I went all out, I'm trying to get the shape to be like proportionally accurate. Accurate to what? I don't know. To the shape you wanted. To the shape I want, yeah, so. I don't know, check it out. Well, specifically to the shape of the inside of the TFT there. And I really needed to have this whole shape be done in Fusion because if any other app you import vector and then you try to do sweeps or you try to do something else with the paths, normally they're like not optimized for Fusion or not even optimized for milling or anything like that. So that's why I like doing everything. And this really helped me really get a handle on splines, the Bezier curves. Yeah, that's the key word there, optimization because otherwise you'll have points all over that are not needed. That's such a ridiculous way to like learn like good tips. Looking over the chat on Discord Brent is asking, does the case snap onto a standard keyboard? Which case? The macro pad. Oh, I didn't really design it to do that but we could design it to do that. Let me know what kind of keyboard you'd like it to snap into and see if that might be an option. But yeah, like onto the side of a keyboard? So it can be like the keyboard extension? Yeah, I didn't think of that. Like the number pad? Yeah. I was thinking of adding some other corner bits here so you can add some rubber feet. Yeah. I think that might be a cool thing. It's just prototyping, right? So I'm not done with it yet, but... Or maybe like a Ninja Flex that just goes all the way around. Yeah, I was thinking that too, but then you need to like be easier. But the feet might be easier. This has weight to it. Have you held this in your hand? Yeah, I don't know. It's heavy, it's like the PCB. And it's kind of bright. It is the PCB and all the keys, but this is fairly thin. Like this was one and a half millimeter thin and then this right here is like a little bit thicker with a little bit of a ledge here so that it has just more. But look at that. Look at the way it's inclining. Here, let me see if I can do... Hold that right there for me. Well, I do the focus. You kind of see the steps there, the way it was printed. Do, do, do, do, do, do. Like this is actually the bottom side that gets printed. And I don't know. Pretty good resolution, right? The stepping of it. Yeah, I don't know. I don't know why I showed that, but that's cool. And so Brent's clarifying, he wants to place the numpad in the middle of his split keyboard. Mm-hmm. Yeah, show me with the split keyboard. Yeah, yeah, yeah. We'll see what's up. It has freestyle too. Do we have a cat and a bird hugging? Oh my gosh. Well, Liz is saying that the irony of the bird being inside the cat paw is that it's inside the parrot inside the cat paw. That's funny, meanwhile at Liz's place, yeah. Okay. Okay, so it's this guy here. That is so cute. There's this split keyboard. It looks like you might be able to have some wedge or something that can go in there. Mm-hmm, that's cool. Nice, yeah. Maybe I can clip on to underneath where the little risers are for that, the feet for the keyboard. Yes, skew the lawnmowers, I know, right? Cool, all right, well. Oh, and then a shout out to Karen in the YouTube. Shout out Karen. All right, that's it for this week's prototype. Well, thanks for working on all of this. Yeah, very fun, fun stuff. All right, let's go ahead and move on to this week's community makes. Every week on Tuesday, we try to 3D print something from the community and do a time-lapse about it and then show it on the show, so. Last week, oh, yeah, sorry. There's a micro cat uphold. Super fun for the office, as we turn back, use this to annoy your coworkers or launch, I don't know, candy or something at them. Don't, you know how it is. Having the office antics. Sure. So here we're just using some LEDs. I don't know how to, they've been in office for quite a few years. No, I'm laughing at what we're using here to cat-bolt. Oh, yeah. I definitely don't use LEDs, definitely poke someone's eye out. This is okay. I'm gonna suggest using candy or something. But this is a remixed design, is that correct? Yeah, yeah. Yeah, this is a remixed design. Bingo Blob put this up here. And he made it ambidextrous. Ambidextrous, yeah. Look at this little chart, V1, when he goes this far, V2 goes that far. Super technical. You can always 3D print the little balls, right, I know. Again. Again, candy, yeah. Easy printing, one solid part, very cool. The original design is from this fellow here. Yep, so you can check that out. So what's so cool about this is the spring or whatever that is being used to act as the mechanism that'll launch. Right, Luke Pansel is the original designer, remixed by Bingo Blob. So take a look at the overhead. So this little thin piece of PLA here is what's providing the spring action for it. One tip, though, for anything that's printed in PLA and you're using any springs, like what was it? One of the torture things, no, no. One of the boxes that had a spring open part, I had to completely throw away because you can kind of see it here. If you leave it latched in like that, the PLA is going to sort of mold over time into that and then the spring won't work anymore. That's what happened there. Right, so there's a tip there. It's just some things to watch out for with PLA. Of course, just want to have them pet G, I don't think. But yeah, there you go. It's a built-in little micro catapult. The spring action here going on. Yeah. It's a nice little, it takes like, what was it, like two hours to print. Yeah, printed place, very cool. Very nice. Yeah, good torture test too for your printer as the angles, crazy. Okay, cool. And then this week's time-ups Tuesday was this low-poly, pokey ball. Yeah, by 3D Mon. I was going to call it the origami style. Yeah, that's what interested me so much about this. The included hinge, or the printed place hinge, and then because everything he needs to be folded together to form the domes for each side. If we take a look at the overhead here, you can see how this is all bent. You print in one flat piece and then you just bend these to create the dome for each half. And we have our printed place hinge there, and then this little guy here clips onto the little hole there. Yeah, that's pretty cool. And then what, it's hot glue to secure those tabs. Yeah, yeah, you can use hot glue for these. It's supposed to like click in, but my tolerances are off. All right, so some glue may be required, that's fine. If your polish is a little bit better than these, it should just snap in, yeah. I don't know what's up with the resurgence of Pokemon. I think you were saying because of new seasons now, you have that new game. Yeah, it's on Netflix. There's like a 2021 cartoon now. And of course, obviously the kid is. Yeah, Gavin's super into Pokemon right now. Like he had a Pokemon theme birthday. Oh yeah, yeah. Super cute. So of course we had to start doing some Pokemon stuff, so there we go. And this was just released as well. So pretty cool use of doing origami to change. So shout out to 3Dmon. Wait, snap fits together. It's a free download off Colt3D, so you can check it out. And it doubles as a great origami. So get your Christmas gear ready. And very, very cool. Pokeball. Got a kid. Got a print-a-ball. Pokeball. Very fun. Thank you, 3Dmon. All right, and then we have some other community makes from the community. So we'll be run through those now. All right. First up, we got a make from John Gallifer on Twitter. He tagged us. He made the Infinity, Infinity Mirror Coaster Project. So here's John showing it off. He is a professor in the Boston area. Shout out to him. He's been on show and tell. He's a frequent show and teller. I wish he was my professor, really. Right? This is so cool. But yeah, he's showing this off. He's gonna use this as a way to teach his students how to make some fun shit. Very cool. Let's just let that one slip. All right, and then next up, we have one from, from Stuart Riggs. I think you're in the chatroom, Stuart. Wanted to share your version two of your multi-pass. So check it out. This is a super awesome demo. Stuart has his code and files on the GitHub. Check those out. It is so cool. Yeah. So you got this super cool light. You got Neopixel. Jewel go in there. It's lighting up, reacting to stuff. And just a really nice OLED display as well. Really good use of the QT Pi. And like putting it all together in the same super rad. A little name tag badge for conferences and stuff like that. Everyone needs to make like their own personal like multi-pass. I dig it. So, a huge shout out to Stuart for sharing this with us. And just making it awesome. Yeah. Check it out. We've been saying all of the upgrades upon upgrades. Yeah. We've seen too much more. We've added something more and better. I think it's like a little piece of acrylic. A rod. A acrylic rod. Super cool. All right, some more stuff here. We got a kind of a remix of the heat set insert. So if you're looking for a way to do heat set inserts into 3D printed parts, we have a device that helps you do really smooth. Linear. Linear heat set insert. So this fellow here found an issue with the kind of bearing plate and remixed it so that it fits a different setup. So that's really cool to see other folks remixing it. The files are all open source. They can download it in different file formats. And that's what I like to see folks making out work for their setup. So that's really, really cool. Here's the original kind of design there. This was a collab project with Bill Binko. So shout out to Bill Binko for that one. But yeah, this is one of the kind of rigs that we needed for our own personal use. And these are the heat set inserts. We even sell these heat set inserts. I was going to say, quick plug, they are in stock. They are indeed in stock. So if you're looking to do some, if you're doing a lot of them, that's really, and you can damage your part if you do it incorrectly. So that's why I really needed to make this. And Bill Binko was, our brains just kind of, we're working on the same thing. He said it got a bolt. He said it got a bolt. Yeah, so, cool. Heat set insert rig, it's out there. And we got one last one here. This is, or actually second to the last one, this is Mario Boo. This is made by Pat's 6046 on Thinkiverse. It got a lot of makes on this one, right? It's a little planter, no electronics, but very fun, a little planter, modeled after the kind of Boo from the Mario video game series. Yeah, you can add electronics to it, make it glow. And I just read the description there. Wow, primer fill and acrylic paint. That's why it's so smooth. Wow. It's super smooth, y'all. Holy crap. Yeah. This is a good one for practicing your smoothing techniques. Yeah. Why not? Very, very excellent. And you can put plants in there. Give it character. Some folks like Uni-Brow, they give them Uni-Brow. Some folks paint it some weeks though. But it continues to keep making things. Shout out 2014. All right. And then the last one, this was Tim C, a foamy guy, better know, aka foamy guy, has a really cool project on the Learn Guide that isn't released yet. Sorry, I'm sneak peeking this. But using the 3D printed, printed place crank for the rotary encoder, it's using the Adafruit rotary trinkie. And it's a way to create a brightness crank. So it's got some really fun things where you have to actually crank it a little bit harder to actually get your thing to work. So very, very cool project. I can't wait to see this released, but I figured I'd show it just a preview here in the Learn Guide. It's in moderation. Yeah, it'll be out later today, I hope. And he has a nice little explanation why he's using the crank to keep the brightness up. So when you're scrolling through social media, you have to work for it. You have to work for it. Very cool. So thanks, Tim. You can watch foamy guy as well on some days when he's streaming. You can, yeah. I'll post a link in the Discord on the live broadcasting channel. Cool. Wonderful. That's the sweetest community he makes. Thank you, everybody, so much. We hope to see more stuff later tonight, because tonight is show and tell. Every Wednesday, it's around 30 p.m. Eastern time, we invite everybody to come and share what they're working on. It doesn't have to be finished projects. It's gonna be ideas, sketch plans, retro gear, work for progress. Always welcome. Yeah. And immediately after that, it's gonna be an hour with Lamar and Phil on Ask an Engineer. All the new products come out, all the sneak peek of what Lamar is working on, and discount codes. Discount codes are back. 10% off. You can get your fill up your cards and check out as the show goes on. All right, so checking out the comments here. Gabe can't wait to build his heat set press. Oh, sweet. And then Fede Albro is asking if we've tried the lightweight PLA. Not yet. We need to get our hands on some of that. Pretty lightweight PLA. We have done some, a couple of years ago, we were playing with different styles of PLA, and even ABS, and some other polymers to make 3D printed, oh gosh, what were they called? Drone guards. Bumpers? Drone guards. Yeah, fan guards, propeller guards for your little drones, your little toy drones. I think we have a video out too, but this was a couple of years ago, and I think the thing we found was ABS was the strongest and the lightest. So ABS won that one. We'll try it again with the low weight. But nobody wants to print ABS, it's terrible. Both, unless you have to. Unless you have to, yeah. And you have it set up and ventilated and all that stuff. Yeah, catapult drones. Yeah, I'm looking at the discord here. Definitely join in that for the discussions as the live show goes on, if you haven't already. Discord.gg slash Adafruit. Cool, don't forget. There's a bunch of CAD models out there if you wanna play with those. And we'll release more stuff as we get to it. Yeah, you can follow us on all the socials. Where's my favorite point number there? At Ecken and at Diopixel. And of course, Adafruit. Post every day. Yes. I think that's it for this show. Cool, we're a little rusty because it's last week, but hey, we'll be here next week. Yeah, there's stuff going on. But getting through it looks like probably at the end of the summer, we'll be back to weekly. We have a floor. That's really nice. Yeah, we've got a floor. We've got a really nice floor. It's been nice to walk around in it. It's been some time with the kids down there. Yep. We've got a bunch of lighting going in, a bunch of fans going in. The pool heater got replaced yesterday, so there's lots of stuff still to finish up. Yep. Yeah, so thanks everybody for hanging in there with us. Yeah. And we'll see you tonight. Don't forget. That's that. I want to show that next week. So this weekend is a bit of a holiday here in the States, so we won't have a Monday show. Normally Mondays are a Circuit-Python meeting, so it'll happen on the following day, a Tuesday at 2 p.m. Eastern time. And then the rest of the stuff is good. Yep. JPs. It's probably going to be the week. Probably the week, yep. I think we're going to see Lamar on Sunday. We may or may not, but we'll hear more about her. But Norma, she does the stream every Sunday from the Descalade data around 8, 9, 10 p.m.-ish. She was doing it a little bit earlier, which is nice. You've been watching 3D Hangouts. How was every Wednesday? Every Wednesday, I do. And then tonight. And then tomorrow, John Park. Returns to John Park. Works out. Yes. Every Thursday at 4 p.m. Eastern time. And then Scott, I think, won't be doing Friday because that's the holiday. Oh, OK. Like, all of your food is off on Friday, so that's really cool. But hey, maybe he'll do it on Thursday. We'll see. Check the Discord, of course, to check that out. Well, I hope we get to do this again. I think soon. I think for the July party. This photo was taking maybe a couple of years ago now. It was one of the last photos. The actual photographer's in there too. Kind of like a wears wallet. Where's Colin? He's in there somewhere. PT's in there somewhere, too. He's right next to Colin. Well, if you're on vacation, enjoy it. It's very nice. And I can't wait to everybody be together again. Yay. All right, guys. That's it for this week. And don't forget to make a great day. Make a great day. Bye, folks. See you later tonight. Peace.
