Can we suck to post my share? Good morning, Andy Callaway and Vince. Hello, thank you for joining the show. All right, I'm ready to... All right, let's go ahead and do this week's awesome project. All right, this week's... Here's the thing. All right, this week we are taking a look at a 3D printed foot pedal. This is a MIDI controller that you can use to add expression to your musical performances. Or if you are just getting started with music, this is kind of a fun way to play around with different effects for your digital audio workstation. So MIDI is awesome. It's a great protocol that's been out since the 80s and it's kind of easy to create your own DIY MIDI controller with buttons and switches and potentiometers and all that. So this week I thought it'd be cool to make a 3D printed foot pedal. And it's powered by the QTiPi RP2040 and of course it's running circuit Python. So this is what it came up with. It's just one potentiometer and the QTiPi RP2040 running circuit Python. I have a little setup here. We have a foot cam this week, folks. So this is the 3D printed foot pedal and this is just a camera feed that I got. So this is my real foot, hello, hello. On the left side, this is the plotter inside of the Moo editor. This is what we like to use for editing circuit Python code where you could use any text editor, but we really like Moo because it's free, it's open and has a really nice zero plotter. So as I'm moving my foot up and down, you can see the plot happening, the data, and you can see the values that are coming in. So in the code, we are using the map range function to map the values for the potentiometer to values for a MIDI CC, a continuous control. So the minimum value for a MIDI CC is zero and the max is 120. So in my musical software, I have it mapped to a wah-wah pedal. So here you can see in the background, I have the foot. You can see the wah pedal moving along with my foot pedal. The data is coming in through Moo and all that's left to do is to, I guess, play some MIDI notes. So this isn't making any notes. I need to play some notes. So you could use a MIDI keyboard or your own custom MIDI controller like this MX guitar that we did a few years ago. So, oh boy, I need to figure out how to put this on. Now I'm gonna mute the microphone so you can just hear the audio, okay? So that's a little June. You can see or you can hear the foot pedal working and the wah-wah doing its thing. So you can map this foot pedal to just about any MIDI CC inside your DAW. Here I'm using Logic, but it should work with just about anything that supports MIDI. So Ableton Live, GarageBand, Pro Tools, you name it, they all support MIDI. There's probably some free open software that I don't know about. So you could play around with all sorts of different MIDI-enabled software. Oh, that's awesome, I like that song. So I've been having a lot of fun with this one and I guess we can jump into the Learn Guide, take a look at the build, a little bit of the code, and then I'll just play some more tunes and different synths so you can get an example and feel of how you can assign the MIDI controller to any range of filters and things. So real quick, I wanted to take a look at the Sonic just jamming out on. It looks just like the guitar. It totally does, it's pink and everything, yeah. That's pretty dope. Thanks, Yanni. So if you head over to the Adafruit Learn site, this is the latest guide that was published a little bit earlier. I can't do it, I have to take my headphones off. A little bit earlier, we got this published. So the Learn Guide just kinda covers all the parts, the assembly, and the code. Really, all it is is just the QT-Pyre for 2040 and a potentiometer. These potentiometers are really nice. These are from Alpha and it's a 10K pot, pretty standard, but yeah, they work really nice for these projects. We also have some odd bits like a long USB-C cable. The QT-Pyre has a USB-C port, so that's why we got one of these. And some hardware, we do have some hardware, and there's some additional things you'll need, like some long screws in order to get the hinge to work for the top pedal. We also have some lock nuts as well, so you can purchase these from your local hardware store or from McMaster Car, which I have linked here. But yeah, that's basically the intro overview. Also have some pre-requisite guides. If you are looking for a MIDI project, definitely check out Liz's guide for MIDI for Makers. This is actually where I crib the code for this project, and I just simplified it down. She has a lot of great examples, not just buttons, but things like how to control MIDI with a servo and the different motors and things. Here's some motor control stuff. So check out all the different things. You can get your creativity juices flowing by checking out Liz's guide on MIDI for Makers. So check that one out. Definitely highly recommend. Some other ones is the QDPie RP2040 introduction that just shows you all the pins and all the features for the QDPie RP2040. Good little refresher there. And then Circuit Python Essentials, which covers all the things like plotting data in Moo and some tips and tricks on using Circuit Python. The next page just talks about the circuit diagram really simple. You've got three wired connections for this one. It's just the, what is it? Three volts ground and the data pin. I have it set to pin A0. So if you want to change that, just make sure you change it in the code. The next page talks about Circuit Python, installing it on the QDPie RP2040. There's a little boot sequence that you have to do to get it in the boot letter. But once you do have it in the boot letter, it's easier to drag and drop than you have to file to flash and automatically install Circuit Python. It's a really fun song and dance that we are accustomed to now with the RP2040. Yeah. So the code page is right here and we're using the USB MIDI library, of course. We also import some things like time in order to get some time-based things from our plotter. We're importing the board, simple IO to do the map range. And here's where our MIDI setup is. So we can change the MIDI channels if we'd like. But for now it's just set up to channel one. And I have the pentatometer here set up to A0, pin A0. Really what you want to do is look at, really want to look at this value here. So in the map range line, you want to change the minimum, right now I have it set to zero in the maximum. That's pretty much the maximum maximum values for the full range of the pentatometer. Once you install the 3D printed parts, you're only gonna get a little bit of the potentiometer. So in my project, it's, I'm not gonna do any math, but it's not the full range. You're gonna want to look at your serial monitor and see what your minimum maximum values are because once you install it, it's gonna be locked in place, the position of the potentiometer. So that's really what you're doing here. So that's why I have the comment there and you'll only get a little bit of the range. So yeah, but it's set to zero in the max so that you can test out the potentiometer before putting it in the 3D printed enclosure. Here's a look at what your circuit pie drive looks like. You just drag and drop the code and the libraries really need to open for this one, which is great. And I have a little note here on the minimum and max values for the pentatometer. So yeah, nice little screenshot there over the thing. So you have two ways to visualize the values, the plotters, really cool. And also the REPL, which is the serial console that just tells you the raw numbers. So you can add those in. In my final project, you can see here it's 33,500. It's minimum and the max value is 48,700. And that gets mapped to zero and 127. Those are the MIDI CC values. MIDI is looking for a minimum of zero and a maximum of 127. So let's say we were doing velocity, zero would be nothing. 127 would be the max hit, max intensity from your MIDI note or MIDI CC, which we're doing here. If you want to change the MIDI CC, you can do that right up here, somewhere up here. Here it is, where it says mod wheel equals control change. It sets a MIDI CC one, which is typically modulation. You can change that around to whatever number. All right, onto the 3D printing part. There is a good set of parts. There's no supports required for anything, which is great. Everything can be printed in PLA and pick your own filament in your own slide settings. If you want it really, really robust, you'll probably want to use something like PETG. I just use regular PLA, which works pretty well. There's a little CAD animation here to show you how the washers are installed. It's a little bit of a thing. So I have these washers that go in between the hinge plate and the top pedal so that there's less friction and it just makes it so that it works better. Then there's a washer at the end of it. So just kind of reference the animation because it is a little kind of order of operations. And then lock nuts to secure the hinge together. Now it's fairly large. It's, you're going to need a 3D printer with a build volume of minimum build volume of 210 by 210. That's how long the biggest part is. So you could try to rotate it up 45 degrees. Maybe that might fit if your bed is a little bit smaller. And if you need any step files or STLs or other 3D models of 8 or 3 parts, you can check out our GitHub repo. We have parts like the QDPI RP2040. If you want to do a 3D model with it, you can use our parts. Cool. When it comes to wiring it up, it's pretty straightforward. I recommend using a short cable. It's about nine centimeters in length. You don't need a really long one. I like using a ribbon wire, which is always fun, but you could use whatever wire. Yeah. All right, this is the assembly page. You're going to walk through this chronologically because order of operations really matter when you are installing. So the thing that gets attached to the shaft of the potentiometer is this little linkage. And it needs to have a really tight fitting. So if it doesn't fit on first go, you're going to want to use a filing tool to kind of loosen up the tolerance, which is what I had to do. Because it needs to be really tight because you don't want any slippage. One thing about this potentiometer is it has like, there's no ridges on the shaft. It's just a smooth shaft. I'm used to like splines and the D shape of this of a potentiometer. This one's just totally smooth. So I had to make it really tight. That's about the thing I want to show you. But once you have the potentiometer secured to the potentiometer holder, and then you put on the linkage, you'll need to test the range of motion to make sure that the linkage can go all the way around or at least 180 degrees. The foot pedal itself gives you about 20 degrees of rotation, which is more than I've seen from other foot pedals, which is kind of fun. So there's that. What I like about this design is I always try to make the part for the microcontroller modular, because let's say folks want to use something else, like a itsy bitsy or a trinket. The cutie pie has a dedicated holder that gets attached with two machine screws. So you can totally take it out and add a new one, which is pretty cool. So whenever you're designing something like that, you're not sure what microcontroller, it's always safe to kind of have it be modular. So the bottom plate is where this gets attached to, and the bottom plate, you can use a different microcontroller. So I don't have to print the whole bottom plate all over again. That's what I was going to say. That is the most important tip about that part, because it takes how long to print this one plate? Eight hours? No, not eight, but maybe three to four, depending on your infill settings. Yeah, so it's always a safe bet, is to make everything as modular as possible. Plus it helps avoid things like support material. So rubber feet help with this build a lot. So I got rubber feet in there and everything gets attached with the screws on the bottom plate. So I like that the whole bottom plate has all the electronics mounted. So the QT pie and the potentiometer are all attached and secured to the bottom plate. The pedal has like this separate arm, which I call the arm, it has a little peg that that's the thing that grabs on to the linkage of the potentiometer. So this one gets attached with two screws and some lock nuts. And that way it avoids some support material, because if you were to try to print the top pedal and the arm combined as one unified body, that peg would need a lot of support. So that's why I just broke it into two pieces. So that's another good way to kind of avoid supports and make it buildable, is to kind of find geometry that would require supports and then just find a way to split the body. Yeah, the hinge plate has its own set of screws and lock nuts to attach to like the base framing. And this one needs to be installed with the orientation in the right way. So one of the ways I made it so that you know the orientation is to add some sort of indicator on the model itself. So here you can see, you kind of see, there's an arrow and that arrow denotes the orientation of bracket. So that's kind of a cool thing, right? So if you're building something and it has to be one way, try to add some sort of iconography or a label or something to your part so that when folks are building or when you're building it, you know the order, the orientation and you can check the orientation by just looking at the part. Pretty cool. And selling the washers is the thing. So you're gonna have to follow it chronologically, right? So I kind of add these sleeve washers to the sides of the top pedal. And then from there, I add in the middle washers to those sleeves. And then once those are installed, you can start to bring in the hinge plate to the top pedal. And that's how that's working there. And then these M3 screws are fairly long. They're 16 millimeters in length. So you need to be able to pass through some thick material. And then one last set of washers, I call them washer caps, because they kind of cap it off so that it just doesn't fly out of place. And I recommend using pliers. We got these really nice pliers in the shop. They grab on to the lock nut because it has a nylon insert and you kind of need to hold it in place. Holding it with your fingers is not good enough so you're gonna need some pliers. Other than that, once the hinge plate is installed to the top pedal, you can start to test the hinge and make sure that it's in a desirable kind of fitting. You kind of want it snug, but not loose. So one of the things about these foot pedals is that it's tight where it'll hold its position. See as it's kind of going up, it kind of stays where you want it to stay. And you can loosen it and tighten it up, but I like having it a little bit tighter. I've probably loosened it up a good amount now because I've been playing it a lot, but I could always re-tighten it if I need to. But so far it's been holding up pretty good. The autonomous is holding up pretty good. So once the top pedal is ready to install to the base, you can just kind of line it up. There's a little opening for the arm to pass through and then you can use hex nuts to secure those screws to the hinge plate. You want to test it out and then the bottom plate gets installed kind of last. So before you fit the tabs together, you want to fit that linkage that's on the potentiometer to the peg on the arm, which is attached to the top pedal. And that's super easy to put that in. Once that's in there, you can just line up the tabs and add your screws. That just kind of shows you the peg is installed to the linkage. Then you can add some screws to the side. There's four screws that they're used to secure the bottom plate to the base frame. And that's kind of it. The nut shell. The usage page just kind of talks about USB mini controllers on a Mac. It's just a plug and play thing, but it will show up in your audio and video setup for Mac OS. It just shows up as a QtPyre for 2040. You can change it. There's some parameters like, I guess you could change the, you can reroute it to other things if you'd like here, but you don't have to. It's kind of just ready to go. Lots of musical software like GarageBand just kind of uses MIDI CC1 as modulation, and most things will. And it just kind of works. And inside of Logic, which is the music software I'm using, it has some particular key commands for learning and mapping MIDI CCs to various fax. And that's it. And a nut shell. Pretty straightforward mini controller. Mm-hmm. Yeah. Cool. Any, yeah. Vince has a question. Is there any risk of over twisting that potentiometer on your pedal? No, because the potentiometer just keeps rotating. No, it doesn't keep rotating, but when you're installing the linkage, I just have a note in there that says, try to have it in the middle, like try to position your potentiometer in the middle so that when you put that linkage in, you'll have a free range of motion. Where is my, oh, I got it, there it is. Yeah, under the assembly, I have a thing here, yeah. Yep, so check that out. But yeah, when you're testing the range of motion, you wanna make sure that you can go past the whole thing. In this photo here, you kinda see that I'm moving the linkage left and right to make sure that I can fully take it. If not, you just pop it off and put it back in. Yeah, the linkage. Cool, good question. All right, cool. And that is this week's awesome project. Posted all the links to all of the files to download and 380 print on your own. You got the step files, so you can edit to have any design patterns you might want on there. This is definitely a, what is it? Like, Aztec inspired design that's going on there. Yeah, I thought it'd be fun to add some. Yeah, it looks like one of those alligators. Right, it's supposed to be like a serpent, a feathered serpent. Quesquetol, I think his name is. It's like a mythical creature. So, very cool. In addition to the Fritz scene and all of the libraries required to get this up and running, all in the discord and all of the chats all over. Let's go ahead and listen in to some demo. So, this is a little synth using, it's called the RetroSynth. And the patch name is Instant Hook Whirl. And what I have assigned to is this ring modulator. So, it's adjusting the frequency. So, you can see the knob is going with the pedagometer. It's a really crazy synth to play with, or a fact. So, that's a cool one. Let's take a look at another one. This one is a sampler. It's kind of a xylophone. And what I have the MIDI foot pedal assigned to on this one is a tape delay. So, I have the delay time. Like the rate is tied to it. So, you can see here the delay rate time is adjusting. So, let's see what happens. It's a really fun one to play with. Delays are so fun to play with. This is called the tape delay. And again, I'm playing with the delay time. This is like a sampler, so these are wave files. Not a digital synth type thingy. What else do we have? The Alcabee is a super cool synth inside of Logic. And this one is called Short Sweet Plucks. And I have the cutoff filter, I believe, tied to it. Yeah. So, cutoff filter is a great way to kind of add expression to synthesizers. Way to wobble. So, this is a retro synth. And I have the LFO rate tied to this one. So, it's kind of a weird wobble. I just noticed you can't see the rate, whatever. It's fine. It's under the foot, but whatever. It's fine. You get it. There's a hundred different knobs and you can assign your foot pedal to any of these knobs, right? That's what's terrible. We got some warm weather. I have a bow coder. I was going to say, do the voice. That's just bananas. So, let me see if I can do this. I'm going to, I have to mute this microphone but still use the microphone. So, let's see what it sounds like. Hello. Welcome to Sookie's microphone. Okay, that was fun. So, yeah, I've been playing around with it and it's been a lot of fun combining your passion with work stuff, so it's always a cool thing. MIDI controllers are a great way to explore music. So, I highly recommend checking out the MIDI for Makers Guide. It'll get you started on your musical journey. Very cool. Thank you. Yeah, a comment over from to Wester, saying the button presses can be somewhat annoying. Everything about CapTouch, as in a certain playground express fun house to emulate. Well, when you're reporting. Right, I forgot to mute the mic. Because when you mute the mic, you don't hear it. Yeah, totally though. CapTouch should be a fun thing. I really like, you know, MX, Cherry MX keys, Cherry MX compatible keys. They're really nice. I picked some that aren't so loud and clicky but you can do whatever kind of buttons you'd like. This is just my jam. I have done some CapTouch stuff and I really don't, personally, I don't favor them because I don't get much tactical feedback. Which is something you really need when you're actually writing music. When you're actually making a song. We're not just messing around when you're actually composing a song. Right, I remember when the iPad came out and I was doing music stuff with it and I liked it for the first couple but at some point, you're touching the glass and there's no texture, there's no... It's like when I'm driving around, I have just the touch screen if I had buttons to feel around where things in. I have to go to autopilot and then look at the screen and actually do what I want to do. So yeah, the screens aren't always the best for everything. Sure, sure. But yeah, there's lots of different capacitive touch stuff we could do. We have a few on the interview learn site. You can check out. And then comment from Ham's lab saying that they have coded a vocoder algorithm from when they did a DSP class a few years ago. Awesome. That's super cool. Yeah, the vocoder and logic is like kind of ancient. It's kind of old. All right, sweet. It's a fun one. Cool. And that's gonna be this week's awesome musical inspired project. Yeah, thanks. All right, take a moment to... All right, let's go ahead and jump in this week's what are we prototyping? This week is a super cool rendition of a CM1 computer. A little connection machine. Yeah, so we're very famous. We're repurposing this as a Raspberry Pi computer case. So much like the very awesome, iconic computers that have the visual system load on the front side here. It's gonna be a bunch of LED matrixes on there. And this is a Phil B idea. So of course he had to have everything nice and detailed. You can see all the little triangular vents that are gonna have some airflow intake on there as well as the top for the grid. And then on the back as well. So all these just pop off. I'm gonna get one of these to come off. You can see the inside here. Oh, let me do one more so you can see more clearly. The Raspberry Pi inserted in there with a little right angle connection for the power. And all the ports on the outside. And if we take a look at the front, we're gonna be using the black LED acrylic. Black LED acrylic is gonna do the diffusion for the Charlie Plex matrices that are gonna go on the inside here. You can see the framing where they'll mount to and they'll go on. We'll have these little Charlie Plexes going on the front on here. We'll have two for each cube. No mount, let me see. Right in there like that. It's cutting a couple more pieces for that. And these just slide right on in. We take a look at a little bit of the detail on the front here. Here's all of the triangular vents that were nice and famous for as well as the egg crate grid on the top. I think the back had grids as well but for our purposes we're gonna definitely add it because of the Pi 4, you know how hot it gets. We also have some mounting options on the bottom here so we can have a nice little bracket that'll suspend a fan in the air and have it have some nice air intake. Tons of supports that are used to print the slide into the frames for this. And of course, all of the internal vents inside here. And we are using support materials. We're using interface layers and a roof. One of the settings that I rarely use and this is one good example of when you're gonna want that when you have all these intricate details. Especially these horizontal printed lines here. They'll hang over way too much if you don't have the interface layer inside there. And the case prints in three different three parts. So we have the back, the front, and then the bottom which has the Pi case on there. Have a bunch of geometry that is doing some like fillets and chamfers so you can minimize the amount of supports that are needed for all of these overhangs. You can see that this is just one giant cube that is then cut up and split up into having all the different cube shapes on there. Go over to the bigger screen. Bigger screen. Have a little bit more of a look at that. And we're using the galaxy glitter filament for this. So it's the black galaxy sparkle filament. And that all does it look good. It also feels so nice. It's got like a oily sort of texture on there. Whatever additive that they're using on there to have those glitter, sprinkle, whatever. Sure. Extrude so well. Texture PEI. Yeah, we got the text PEI for all of the fronts on there. So you can see a very nice, it doesn't look too 3D printed. And you can kind of see the layer lines there. But this will be about in two weeks. Philby has got some code written up. You can get all these to display system load or maybe like whether I need like a time or something to remind me what year it is. I keep thinking it's 2021. Philby on last week's show and tell you can see his breadboard layout and everything working. Definitely tune into that. We'll be soldering wiring things up this weekend. Excellent. So super cool. And you did cut these up with the CNC mill. Yeah, or you could just use a paper template. I like to use the mill because I can do a batch of them. Yeah, so it'll be super exciting to see. I know it's a little bit hard to get that pie four but definitely sign up. We did have some in stock that going out in batches. So be ready to have that 2F authentication. Ready and set up when these go back in stock. So definitely a super awesome octoprint case for one of the printers. Is that what I'm going to utilize this for? Yeah, so cool. Coolest pie case. Right? Very, very dope. So this will be available in about two weeks. Super cool. Two weeks. Two weeks. And that's what we're prototyping. What it actually looks like. There it is, the famous. There it is, yeah. Connection machine. They showed one of the versions inside of Jurassic Park. Right, the Ned's in the background. Yeah. Or it's the Borg ship. It's just a cube. Right? Yes, that is the one, Ham's lab. That is the exact same one. Very cool. Slides in it. A little acrylic piece. There you go. How many, so how many of these are you going to have? Four. Two, four, six, eight. There's only eight of them, folks. These are the driver boards. The IS-31FL-3731PWM. Yeah, we'll have to do some addressing for the backs there so we can get the addresses assigned. Yeah, and it's all I2C. So zero clock, zero data. Yeah, all one, or two wires for that. And Raspberry Pi. Super cool. These are dope. All right, and that's what we're prototyping up. Yeah. We're going to use up all those Charlie Plexes. Oh yeah. How many LEDs do you think that's in total? Maybe 200, whatever times they eat. More than that. Maybe 512, something like that. I don't know. A lot. Let us know if you can run the numbers so quick. Very cool. So that's this week's, what are you prototyping? Yeah, yeah. I should like... And that's this week's, what are you prototyping? Next up, we're going to do Shop Talk. Shop Talk? Community Makes, no? Yeah, I don't have anything for Shop Talk. Community Makes. Oh, that's great. And that is Shop Talk, but I don't buy them. Let's go to Community Makes. This week's Community Makes is this super cute little stand for the little mini hot plates that we have in the shop. It's for the MHP30 hot plate. It's the only hot plate that we have in the shop, I believe. Yeah. We're just one. Some of the questions we were having is, is this just cosmetic? Why does it need a stand? So when you start using third helping hands, what the designer of this was saying that they wanted it to reach up to their Haku third helping hands that they're using or their VICE and adding that 71 millimeter height to it was the only way to get that to reach their third helping hand. So it's super easy, it just press fits in and you even have a little screw hole to connect to the bottom of there. That board will not fit, unfortunately. This one what? I mean, kinda. If you're gonna do chips like that, you can rotate it around. Somebody has, there's other like more little add ons to this, you can have it like hold it. So you can like hold bigger boards is what I meant. So you can have it like positioned at certain ways. So there are more different little additions that you can add to this little guy. So I just thought it was a nice simple way to promote this super cool little hot plate that people always ask where Lamar got it from and is in the shop. I also wanted to show how big it is compared to like a, you know, normal sized hand, I guess. The hole is for I guess securing to. Oh, it's gonna go to the bottom there. So there you go. So you wanna attach it to something and be good. Maybe a tripod screw adapter, but that is pretty good too. It needs to be level, you don't want it to be level. Yeah, I mean, if you're like on a boat soldering or something or some sort of some gimbal or something would be good. Yeah, cool. And that's what's week's time-lapse. I have a link, Vincent's, everything needs a stand, especially a pink stand. Let me pull out the, what is it, Thingiverse or Prusa? It's on Prusa printables. Right, we got an update from Prusa printers. They have a new name, printables, or as I like to say, PrusaBalls. Let's take a look. So, PrusaBalls is by Kevin. Renamed, and this is from the designer, Kevin, who put this up as a free download on PrusaBalls. I think you can kinda see the little vice that he has in the background there. Cool. Is it printed in Resilent or something? I don't know. I don't know. I see other lines. Yeah. My rendition of a riser stand for the MHP30 miniature hot plate. This brings the top surface to a height of 72.5 millimeters, which happens to be the lowest configurable height for the Haku C1390 Omni-Bice. Oh, this is a Haku Omni-Bice? Tell me more. Check it out. This is a really dope one. Looks like a stick shifter. Yeah, this is called the Omni PCB holder. Tell me more. What's this? What's this about? Like, stick shift looking thing. I wasn't planning this. But anyway, we have research to do now. We have homework. Oh, I want one of these vices. Yeah. Haku C1390 Omni-Bice. Very cool. And it attaches with a 60 millimeter M3 screw. Cool. Shout out to Kevin for posting that up. All right, moving on with Community Makes. We have some more fun things that folks have shared with us. And we're super excited to share. So first up, I mean, next up is a somebody, okay. Somebody, you have a name. Prusable's user RNGPT posted up their make of a foot pedal. So they say, did it have the right setup for the support material? It's kind of rough, but eventually it will be smoother. It prints really well, waiting for parts to finish the build. Cool. So not a foot pedal, but a foot switch. This is our classic foot switch that uses a RNGPT M0 and a Zippy microswitch. Lots of foot pedaling today. Very cool. Oh crap, I didn't show any of that. I'm sorry folks. So this is a make of the USB foot switch controller posted up by Prusable's user RMGPT. And there is their photo. Kind of a neat looking, let me just have like a cyber something, cyber foot switch. Cool. Yeah. And there was a comment about support material, but you could smooth it out as they said. Okay, give me a sec to pull up the next one. This is quite possibly my favorite make of this week. Two weeks ago, we released a 3D printed emerald inspired by Sonic the Hedgehog. And this week, MC posted up their make of the, sorry, sorry, sorry, of the thing. It looks fantastic. It's a principle on a Prusa in their comment is great project. Thanks, my kids and my kids love it. And I enjoyed building it. I'm new to 3D printing and also haven't done anything with Adafruit stuff. This was really interesting to me. The Adafruit circuit playground, Bluefruit was on back order. So I got the classic instead and had to do some Arduino programming to turn to green. It was fun. Also added a tap to change color option. And there's a video of the MEO link. Should we take a look? We have time, right? Yeah. Safari cannot open. It's invalid. What does that mean? Safari is like, no, that's not a real link. Oh, because it says it's unsafe. Like it says unsafe, should be fine. 3D printed Sonic the Hedgehog chaos emerald from Mike C. This is showing through in the video, Peter. Cool, so you can tap to change it. Yeah, because there's built-in accelerometer on the circuit playground classic and all the circuit playgrounds have the excellent. That's a really good one. Nice. It came out fantastic. Ooh, I love the white one. Super cool. So just tap it. Very cool. So thanks to Mike C for posting up their make. How cool. 3D printed Sonic the Hedgehog emerald. Trying to get my stuff. And the last one this week. Wait, there's two more. Get through these fairly quick. Man, everything's on Prusa printables this week. This one is a make posted by Rev Null on Prusa principles. And the Raspberry Pi face case. This is a case for the Raspberry Pi V plus. And it looks like a face. It's a very fun one. It's the case that I use on all of the printers for the octave print. Love the mouth because it has the camera ribbon opening for it. It's fun little case. Face case, if you will. All right. And then the last one this week, folks. Last from the past. Get ready for Halloween. Comic Con. Capy, larger eyes. Again, I'm principal. So FAIQ posted this up. Their remix of Capy. Ah, so Capy is a character from Mario's, one of the Mario video games from Nintendo. And this uses the monster eyes. And they animate, they're kind of easy animated eyes. And FAIQ posted up their remix. So it says, love the idea and decided to make one, but the eyes were a bit off and they didn't cover the wear and mild damage that happened when I removed the previous eyes. Yeah, so you want to fashion it for your own hat. All right, so that's a hat that you want to, you want to make it fit your hat. So you scale it appropriately. And it says, I made the slots on this side smaller so they're not evident, but still can fit a needle and thread through. That's right, this is sewed. And the back threading was not noticeable. There's enough room on the back top to manage the controls and no one noticed the back. Cool. Tip, I placed the lipo battery in between the lining and ran the wires through the front behind the eyes. I was able to place a larger battery because of this. Sweet, I printed the eyes in white. You really only need one, double it and just flip it and slicer. I did not show the print lines. I did not want to show the print lines. So use the circular fill. Yeah, that's cool. Hence the gaps, not noticeable. Yeah, you can use a concentric pattern to make it nice and less noticeable. So you only need supports for the slots on the side. And this is printed on a Prusa. Three, okay, three. Very cool. And there's the original with our lovable friend. Why is his eyes red? I guess it's supposed to be like that, huh? No, that's cool. Yeah. You made a face. Oh, Pedro, through photos. And that's this week's community makes. Shout out to everybody for posting up their makes. Thank you so much. Shout it better. All right, cool. And that is it for the show. You got more show going on later tonight. We're hosting a via show and tell. Yeah, so we invite you to come on this week and show off all the things. It'll be 3D printing, it'll be electronics and crafts or like a little tour of your workspace. I hear folks like Floppies. Let's see your Floppies. Retro tech. Retro tech. Some old school tech is always welcome as well. So definitely tune in at 7.30. Careful with that. E.T.? Nah, just hear it when you tap. Whatever time. E.T. Yeah, so come on by. We'll drop a link in the Discord chat room once the time comes. Yep, 10 minutes before. And then right after that, it's gonna be full hour of Ask an Engineer with Lamar and Phil. Take a look at all the cool new things coming out. News from around the maker community and top secret stuff that's being worked on. That's right. And is it this week that John is off? I don't remember, is it this or next week? I think it's next week. Yeah, okay. Usually on Thursdays, 4PM E.T. Or yeah, 4PM E.T., Jet Park's Workshop, awesome projects that he's working on. Some cool mini stuff, some collabs with Todd Botts. Definitely tune in for that. I think the first guide went up. So definitely check that out. Tips and tricks. Excellent. And then Fridays, tune in. Deep dive continues while Scott is on maternity leave. Tim is taken over. Tim, foamy guy. So you can see it in the submarine there with Blinka doing some deep dives on some cool vector graphics inside of CircuitPython. So definitely tune in every Friday, 2PM. He also does a lot of really cool streaming on his own channel as well on Saturday. So definitely tune in to Tim. Yeah, 2PM Pacific time, 5PM Eastern. There you go. We're on East Coast. This, oh, continue around the brown, yeah. Continue on to the week. Sundays, Lamar, Laydata streams live from her desk, from the desk of Laydata every Sunday night. Yeah, it features the great search with Digikey. Take a look at what are the components are being updated to, or boards are being updated with components that are available. So Laydata take you through, searching through Digikey sites to find a compatible chips. Okay. Do I need to tune in for that? Mondays, this is CircuitPython meeting. It's where all the CircuitPython devs come together with the community. Every Monday at 2PM, Eastern time. That one's on the Discord server. All right. And don't forget Tuesdays. JP's probably pick the week every Tuesday at 1PM Pacific or 4PM Eastern. We can get up to 50% of select picked items. It's crazy, but it only happens during the live show. So definitely tune in then to get sure. Automatic, 50% off. Yeah. You've been watching 3D Hangouts every Wednesday, 11AM ET. Last week we had a little time to work on these projects. I say it was spring break, but we were actually just finishing up these projects. Yeah, yeah, yeah, yeah. Very cool. All right, that's it for the show. Yes. Thank you everybody for tuning in. We'll see you later tonight. But until then, don't forget to make a great day. See you there tonight. Jam it. That's all I got. That's all I got. See you guys. Thank you everybody. Thanks so much for hanging out, guys. See you later. See you later tonight. There goes my thing. Bye, folks.
