 Hey, what's up folks, welcome back to another 3D Hangouts. My name is Noah Verwezz. I'm a designer here at Adafruit, and join me every week is Mr. Pedro. Good morning, everybody. I'm Pedro Rez, creative tech here at Adafruit, and every week we're here to share with 3D Printing Projects featuring electronics from Adafruit. That's right. Is it sure we combine 3D printing and DOL electronics to make inspirational projects? Hello, everybody. We're hanging out in the Discord chat room. The Discord tunnel. Good morning, everybody hanging out. Good morning, good evening, good afternoon, good night. Wherever you are around the world, giving shoutouts to everybody hanging out in the chat rooms, we are hanging out in the Discord at discord.com, you know, discord.gg slash Adafruit. Everybody hanging out in there. We're in the YouTube chat, on Facebook, on Twitch, and all of the other streaming services like Periscope and LinkedIn. Yeah, we fixed LinkedIn, I noticed, so that's great. So we got all the different channels. Shoutouts to Jim Henderson. We got Gary Z. We got CW, Flemmer, Dan T. Us, Garrett, and Ryan Anderson hanging out in the YouTube chat over on the Discord. The usual suspects hanging out. We got Mr. Certainly Bruce, UHA07, and over on Facebook as well. Good morning, everybody from sunny Florida. All right, we'll kick off the show with some of the housekeeping stuff. We'll first start off with the freebies. So if you wanna pick up anything in the Adafruit shop, there are some freebie deals going on. I'm gonna skip the details, but if you go to Adafruit.com slash free, you can see all the different tiers. There's something for everybody and we're still doing the 100 days of masking. Next up, we're gonna talk about the Circuit Python meetings that happen on Discord every Monday at 2 p.m. Eastern time. It's a great way to check in with the community and the fine folks that are developing Circuit Python. This happens on the Discord server every Monday at 2 p.m. With the exception of U.S. holidays on the Monday, it'll proceed on the following day, but you can hit up adafru.it slash discord. That's the alternative link to get invited to Discord, so check that out. We got newsletters as well to run through, so the daily newsletters, you can subscribe to all the different categories that we have set up by heading over to AdafruitDaily.com and you can subscribe at your own leisure. And then for product-focused newsletters, this one happens once a week as new things get added to the Adafruit shop. A good way to get that in your inbox is to subscribe to the news newsletter. Adafruit.com slash newsletter for that one. Sweet. All right, Adafruit's shipping the order safely. This is a pre-COVID photo. So your orders support everybody here, so we appreciate y'all ordering things every now and then. I feel like we need two Photoshop masks on everyone just so we don't have to say that anymore. Yeah. But then it'd be like, it's not six feet apart. Maybe this one helps? No. No. So keep your mask on, even though people are telling you not to wear it anymore. It's crazy. We still stand by, you should wear your mask. Which means that we still have a free mask with every order? That's right. The black surgical ones. I guess 100 days of masking, we still got days. Wish we could do 1,000 days of masking. All right, well, I think that's it for the intro stuff. Oh, don't forget, Jobs Board, Adafruit has a Jobs Board. Check that out at jobsandadafruit.com. If you're an employer, if you're a maker and you wanna post up your skills, you can do so for free. Also, if you're an employer and you're looking for some makers, you can take and browse folks' profiles. And all of the job offerings and screenings there are screened by Lamar and Phil themselves, so there's no spam here. But yeah, check it out, jobs.adafruit.com. All right, then jump back over to the Discord chat room and say hello before we start jamming out here with our project. Hello, hello, we got Vince joining in. Hello, chats. Over here on the Facebook. Good morning, savey. Thank you all for hanging out this lovely morning. Yeah, are you folks ready to jump into the current project that we're working on? Let's go ahead and check out this super awesome Pico MIDI. All right, so this is our project that we're working on. It's a collab project with Liz Clark and it's basically a MIDI device. So if you've ever heard of the MIDI Fighter from DJ Tech Tools, it's basically a MIDI Fighter. It uses arcade buttons to make a musical instrument that can be used with anything that supports MIDI. So in this case, I have a little iPhone here set up with GarageBand and the Pico, the Raspberry Piico is the brains and the heart of this project. So the Pico is that board, dollar board that came out in January and it can run Circuit Python. It can do USB, HID and there's a really nice MIDI library for Circuit Python that runs really well on the Pico. The Pico has tons of GPIO enough to get an array of 16 buttons. So that's what we have here. So during January, I was doing a beat a day and one of the things that I kind of wanted that I kind of came up with an idea is that it'd be really nice if I could program and change the notes while coming up with the kit instead of having to kind of tweak the code and change the values. I thought it'd be really cool if we had a display that could do that. So Liz put this together. This is an OLED display. It's a grayscale version. And the idea is that she put together a grid of 16 circles and each circle has a number and that number is a MIDI note. So if I wanted to change this note here, I use this five way joystick, right? So it's very intuitive. As you kind of move left and right and up and down, you kind of get this expected UI behavior, which is so good. So you have this little selection here, this little stroke, the outline, let's you know what button you're selecting. And let's say I want to change this key here. Right now it says it's 70. Is that seven? Yeah, 78. So I wanted to change that. I can click in with the joystick and now the LED is lighting up, letting me know, hey, this is active and you can change it. The display now shows this giant circle with a number here and that's telling me what the number is. So now I can either use up and down to go up and down in the note or left and right to go back and forth. So it's really intuitive that way. And with it blinking, it's really nice. Also you can press the button to see is that the right note that I want? And that is the right note. I'm gonna put my headphones on so I can kind of hear what that note is. So once you've, so that's great. Another really cool thing is while it's in edit mode, right? I'm editing this. I can play notes around it. So I know that that's the note I want. So I'll just go to a different MIDI software instrument. And this is GarageBand on the side iOS device here. So when it comes to latency, I don't seem to notice any. So that's really good for live-performancing. Like it's working really, really well. So that's a little demo of kind of the idea behind the screen and the joystick. Yeah, so that is a quick little demo of it. You can hold as many buttons as you want down as long as your synth can support. Like you could probably hold it all the town, which is kind of fun. Yeah, so the LEDs will stay lit as your button stays held down. So that's really nice. As you release, the LED turns off, so that's really cool. And I have notes, because it's a lot to cover. But yeah, if anybody has any questions during the stream, you can throw them into the Discord chat room and we'll kind of answer them. So again, this is all running Office Circuit Python. And Liz Clark put the code together and we're collaborating on this one. So yeah, we talked about the USB MIDI library, which is for Circuit Python. We have quite a few different USB MIDI projects as well. And the reason why we're using the Raspberry Pi is because it just has all those GPIOs that we need. Okay, so I'll talk a bit about the case design. So all the parts are 3D printed and you got your button grid over here and over here you have the display, the joystick and the Pico. Underneath the Pico is an LED driver, which I can show you folks right now. It's this LED driver. It's a fairly new product and it runs over I squared C. So you can daisy chain it because it has Stemma QT. So that's actually how we're doing this. We're daisy chaining the OLED display and the LED driver here. So this is kind of a does double duty here. It can be a GPIO expander or it can be an LED driver. In this project we're using as an LED driver and really, really nice to have the Stemma QT connection so that we can daisy chain our things together. So that is currently in stock, it's only $5. So if you wanna pick that up, I think it's really nice. Let's say we wanted to do this project with a feather. Feather doesn't have all the GPIO to do a 16 button with LEDs. So you can have multiple. You can, I think you put four of these together and have a crazy array arrangement of more buttons and GPIO, so that's really cool. And you can do some fancy current dimming as well with LEDs if you chose to do so. Yeah, and then the second product is the display. So it's an OLED display. It works really well with Strikapython. It's a greyscale display, 128 by 128. They're in stock right now and there's two Stemma QT connections on the back too, as well as breakouts. So it's really nice to get all the pins you would want for making a display run over I squared C in Strikapython. Sweet, right. And then the Raspberry Pi Pico is in high demand and they're out of stock because they're in high demand. But that's $4 board, you can get it at different places and yeah, we just really like it because it works with Strikapython really well. Yeah, I'm posting all the links to get all of these. If any are out of stock, you can click on the notify me and get an email when those get back. Cool. The next thing I'll show is these LED buttons, right? So there are several different LED type of buttons. The enclosure is designed for these 30 millimeter diameter buttons and they have the LED built into them. These are really nice because they have the LED built into them. They come in different colors, which you can get but I really like the white one because it just is gonna match whatever color I choose, I think. So yeah, the markings are a little different, I think, in our latest thing, here's one of them. I'll see if I can turn the thing on. I just wanna show the button here so you can see, oh, this one doesn't. So some of them are gonna have markings and some of them are gonna have markings. So this one does not have that marking. But yeah, this right here, the gray is the button and down here is the LED. And that's how I kinda tell them apart. And they're pretty responsive, right? They work really well. They have this little hex nut that you screw into so they're pound-mounted that way. And yeah, I like that it's nicely diffused. It's a nicely diffused button. Fun, fun, fun. I wanna change it back to that. That thing, but I'm afraid it'll, it might not like my sticky button. Vince, on the P-code, it has an entire Linux distro? No. No, this is completely different. From the Raspberry Pi. Yeah, it's a microcontroller, it doesn't run Linux, it can run... Sugarpython. And MicroPython. And MicroPython. And then one day, probably Arduino. Probably Arduino. So think of it like that way. It doesn't have an operating system. It is a microcontroller, like an Arduino. Yeah, yes. Very cool. All right, we were back to my notes and jump into Discord chat room. And we got questions about more stocks for the Picos coming in. Yeah, as soon as they come in, we'll put them right in the stock. There seems to be a little shortage, global shortage on chips. So that is why. Yish. And it's not just us, it's global. Yeah, that's the whole reason why we're still waiting for that model Y to come in. So one last thing I'm talking about, like feature-wise, this 3D printed handle I talked about maybe a couple of weeks ago now, it has a printed place hinge, which works really well to make this handle. But I really wanted to turn it into a kickstand as well. So I've modified it so that the handle can click and lock into position and then it can be used as a kickstand. This edge here, I drafted the angle so that it's at an incline here so that when it is on a flat surface, it is popped up a little bit. It gives you about like 12 degrees. So that's really nice as a kickstand. It also works as a handle, of course, too. But I really like that added feature. Just those two things, like there used to be a hole here that clicks in and you can unlock it. You can click it back in and now it'll stay in place there. And I like using the silicone mat as it keeps it from slipping all over the place. So that was a really neat one. What else can I talk about? So it's, I like to do snap fit enclosures and there are screws here, but they just secure the components to the top piece here. But it is a snap fit enclosure and it's really easy to kind of open it so I can do this right here and then just take it apart. See what I mean, it's right there. I'm going to... So that now none of the middies will get mis-triggered. But here's a quick look at the wiring. The previous edit had the Pico and the LED driver mounted to the bottom, but now I have switched it because if it was mounted to the bottom, but it had all these wires kind of coming this way. So now that it's mounted to the top, all the, everything's contained in the top here. And the only thing that's mounted to the other sides is this here USB extension cable, which is nice. It's a stock cable. I didn't have to cut it, which is normally what I have to do, but it's a stock cable and it works really well, right? So all the grounds here are the buttons are all shared together. So they're all daisy chained and then there's a ground pin available in the display here, the OLED displays, that's really cool. And then you can see here that I got the daisy chaining, basically both of these STEMIQT connectors are being used up. So one goes to the Pico and the other one goes to the LED driver here, which is right there. Yeah. And then the, the PCB mount has like three layer, three, yeah, three stages of like stand offs or it's a good amount of stand offs here. That's funny. There's M3, M2.5 and M2. So all of the M's, which is really cool. Now to get the five way navigation switch to fit and to be panel mounted, we have some clever ways to go about doing it, right? I'm gonna close it back up and then kind of show that off here. So three different ways to mount a five navigation switch. We designed our own PCB. At first we milled it, right? So we CNC milled this one and we routed it in a routing software, whatever software I'm trying to focus. Here we go. So it's really, really cool way to kind of quickly iterate a thing. And then we turn this over to Oshpark so we can get silkscreen and a nice routing and you know, gold or copper plating here through whole plating really well. You get that nice stuff. So there's two different things. And then Liz thought, hey, we should 3D print it as well. So she put this one together and this can still come off here. Careful. Yeah, I don't bend the legs or whatever. No, like stab yourself. That's how I stab myself for moving one of those. Right, so yeah, it's a great thing that you can 3D print every aspect of it, even the PCB for this little guy. So the idea is that you would just solder to these legs here and then you can bend these down to kind of hold it more in place. And then these mounting holes here are designed to fit into the top panel. So that's really sweet way. So you get up, down, left, right and then center to click. So that's really cool. So we have some options. Folks can mill it. They can get it to Oshpark or just 3D print it. I think a lot of folks are just gonna 3D print it because you can totally do that. So we wanted to make this as accessible as possible, right? So another thing that folks might not have is that this little window here is a bit of a feature to it. It is CNC milled. You could laser cut it as well, but we thought, hey, why don't we, not that one, why don't we 3D print it as well? So I designed a little window here that is this one. I designed a little window here so you can see that you can still get that effect. It might not be as clear as this, but you can print this in different translucent PLA filament. And this little lip here is designed to kind of have a tight tolerance so that it has some surface to grab onto. So that's why I have it designed like that. And then this lip here will keep it so that it won't be pushed all the way down. So that's pretty neat. And I also have one here that's cut out so you can get style-y and maybe make it say something like midi. Midi, M-I-D-I. That's the midi logo. I just brought in a fusion and did an extrude. You can make some cutouts here and have some fun. So everything can be 3D printed, the PCB and the acrylic window. So those are the latest kind of things that I wanted to share on that. Yeah, that's right, I have to activate it. So we're working on the Learn Guide for it and we'll have it ready by I think Wednesday of next week which is what we're aiming for. But the code is already available on GitHub if folks wanna get on it. It's in the Adafruit Learn repo so folks can check that out. I have a link here. If folks wanna check it out, it's already public. So check it out. And it's commented too, so you can get a good look at how everything is working. And if you wanna change in the pins or add more buttons or less buttons, it's all commented so you can read through it. Awesome job by Liz. I'm gonna revert to my notes again to see if I covered all the things I wanted to cover. I'll post it on the links to everything we're talking about and there were some questions about the clear acrylic that we went over. Yep, it is CNC'd and not laser cut because I don't think you can use a laser on a PCB, right? Yeah, so the way you could laser cut it, it would be like a straight cut. I don't think you can do this with a laser. If anyone uses a laser, can you do sort of this sort of shape in lasering? I don't know if you can. But there's basically a small lip here and that allows the case to have some area to lock into. So yeah, this one's CNC milled and we have some more stuff that we'll talk about with CNC milling after this demo. But yeah, this is some fluorescent green acrylic that I got from Inventables and there's a lot of different fluorescent UV reactive kind of thing. And then pulling off of that, I've posted the link to the layer by layer on how you made the cool patterns with the CNC. I don't know if you wanna talk about that yet. Let me move it a little further down in the guide. And then we have some comments for Gisketsky May software. Portasonic is asking if you've tried SunVox. I have not. This will work with just about any of the, you know, anything that can accept MIDI. I don't think I have Nano Studio in here but that's like my other favorite piece of software that I like to use. I'm using an iOS device because it's like the easiest way I can get this working with Wirecast right now. And if you're noticing, what is this dongle here? The dongle takes the lightning connector and gives you that USB-A connector that you can plug in any camera or in this case a USB MIDI device. And it's a native USB MIDI device. You plug this in and it says the vendor is Raspberry Pi Pico, which is really cool. And then to get audio out, I have this audio cable. It's just a regular 3.5 millimeter cable that goes into my little USB mixer that's off-frame over here. But that takes both of our mics plus this has a line in and it lets you guys hear it. So that's how that's working. Yeah. I think next week I'll do like live, like setting up a drum kit. I think that'd be really cool to do just to kind of showcase that workflow of like kind of coming up with the kit. And for me, like that's like my jam is like coming up with the kit and like there's some standards that's definitely that I'm used to that I want to talk about. Like I like to have my kicks over here. My Tom Tom's right here. I got my symbols over here. And then normally this is the kick. But anyway, I'm getting ahead of myself. Yeah, so to work with any MIDI software that takes and accepts an external MIDI device. Yeah. It just works by the way too. Like you just plug it in for GarageBand anyway. Just plug it in, it just sees it. There's no extra setup that you have to do. That's normally the case with iOS devices. They handle MIDI pretty well, I think. Yeah, Portisonics, man. This is a, looks cool. I'm just gonna set a reminder for when the project is released. And just set up one of the Hi-Bos or Keevo from, I think that's the Pyramon, you want? Yeah, sure. I'm just a real big fan of arcade buttons. Like they're the responsiveness of them and they're just so, so nice. I know they sound a little bit, there's different arcade buttons you can get that have less of a clicky sound. But when it comes to like a tactile feel and stuff, they're just my favorite. This is like the first one that's like a true MIDI device that's running off CircuitPython that I'm working on. Yeah. Super dope. They're the same. All right, that's the message. Portisonics saying, yeah, they're using the Keevo together with the Akai unit, or Akai unit. Yeah. Cool. And then more comments on, yeah, the laser would not be ideal for that lip. Yeah, on the lip, there you go. It's a bit of a flange. Yeah, yours. And then requests for an eight by eight sized Pico one. You do have one for two. No, that's four. Eight by eight. So, that's where you want to get, or three by three. You would want to daisy chain a few of these together and then you get all the GPIO and you could probably even use the feather. I would really like to use the feather here, but it just doesn't have enough IO. I'd have to use more of these. But yeah, you could use more of these here. It gives you 16 more GPIO. Oh man, that focus is awful. Let's see. Plasma dolphin is saying, yeah, it would be more expensive with all those buttons. Yeah, the more buttons you add, the more costs you add to it. I think you could get some cheap buttons from like AliExpress, Alibaba. They're going to take a month or whatever to ship. That's on you. You can choose whatever buttons you want, which is really cool. Yeah. Then Robbieaz123 is saying, this looks fantastic. They just got the Akai MPK mini. They start learning and making some synth music. Do we have a kit for this next week? Depending on how many people build this or show interest, then that'll dictate whether we make a proper kit. The last kit that we put together, I think was the Light Saber kit because just a lot of folks were searching for it and our CS team compiles all the stats and they determine that's how we get a kit when folks are searching for it. So search for it, I guess. I don't know, like a midi fighter. Just search for midi fighter. And then questions on, could you replace the buttons with pads instead? Do they have pads? Pad, like a button? Like instead of being a button, it's a pad? Yeah, so we have something like that already and that is a Neo Trellis device. That's what you would want to look at. The Neo Trellis has that rubber elastomer pads. That's the closest thing that we carry, we design, we make sort of thing. So Neo Trellis. And I will be honest about it. I, for performances, finger drumming, these are very mushy and not as responsive as arcade buttons. If you're doing a step sequencer, that sort of thing, a step sequencer, that's great. But for what I'm doing, like performance pressing and the responsiveness of it, these are mushy. I don't want to, you know, just for this application, I don't think it's the best, right? But it's still a great device. But yeah, this one's kind of already ready to go and it already runs midi natively. But yeah, it also can be Arduino and Circuit Python. And there's quite a few projects in the learn system that shows you how to use it as more than just a midi controller. You can use it as a sound board, which is really cool. And here's that 8x8 pack. If you really like the pads, the rubber pads, here's an 8x8 kit that we sell here. It runs an M4, which is perfect. Yeah, that's cool. Buttons, buttons galore. Cool, any questions? Just comment on people wanting a drum machine. I could put a link to the learn guide on a couple of them. Yeah, let's see. I think next week I'll switch it up to a drum and then, you know, we'll create a drum kit. A couple of different ways to do that. For sure, yep. Even a servo driven drum machine. Right, it's a Illinois driven drum. You want to hit a real drum. Yeah, there's plenty of fun drum machines in the learn system. We don't have a midi fighter yet, which is why I'm happy about this. Super cool. And then comparisons with the Neo Trellis between that and the Neo Trellis. Yeah, for me, it's all about the button response and feel. And the Neo Trellis, if you don't want that responsive quickness, like I just can't do that. Like I can't do that with the buttons on the Neo Trellis or any type of rubber elastomer thing. I actually bought one of the Akai drum machine midi things quite a few years ago and I never used it because they just never felt responsive enough for me. Like they just felt terrible. I think it was from Akai too. A little midi kind of soft pads. It's all preferences. 64 haps is saying that the, I think he's talking about the arcade buttons, saying that they look real mushy during prolonged periods of playing it. It does start to hurt your fingers. Soft pads, definitely the way to go. Yeah, it depends, yeah, it's all preferences. Yep, I like to work out my fingers. I think it's easy to work out. It's pretty easy to hit these. Yeah, if you want like really responsive buttons, these Sanwa buttons are the most responsive and they have different styles that are designed for like super rapidness. It's almost like a Cherry MX switch with different colors will tell you like which is the clickiness or which is the responsiveness to it. There's ways to like dampen the noise too if you really want. Yeah, it's funny. But like there's, oh yeah, that's what they mean. Yeah. But hey, you're free to use whatever button Yeah, that's why there's so many different types. Correct. It's great that the LED is built in. The ones I just showed you don't have LEDs, but some of them do. People will say in some button slicers and they're posting links to what one looks like. Looks like a little dampener. I might need a spudger tool. I might not, we'll see. Yeah, I don't think I have a spudger tool. Do we have any type of, maybe that audio cable? Yeah, let me see if that audio cable will work. So you can totally hack these and I don't know if this is the best use of my time, but why not, right? And then some comments on the arcade sticks as buttons will make your fingertips numb. I've been modded there, midi fighter. It's used to come out. And then general questions about the software. Are they able to do velocity through the pads? These currently do not. I've actually never opened this one. That's funny. Yeah, there's the PCB for the LED. And I suppose you could put some rubber, something. Something in between here. But yeah. VP is saying, 3D, pin the buttons. We totally have. We actually did quite a few years ago. You can totally do it. I had a spring inside there. They feel terrible though. They just feel terrible because of the layer lines. Yeah, I think that's where you wanna add the dampener. Marky is saying that the sunwood buttons are just on and off, no velocity. No, yeah, no. But we were thinking maybe some knobs and things to do, either modulation or like you said, the midi velocity, no velocity. Yeah. It looks like we've ended. What do you mean? Let's see. How? Oh, okay. Yeah, I see that it's like... Error. All right, bear with us, folks. Yeah, it says, we're not streaming. Right here. No, we're still live. Okay. That's weird. Yeah, it's a weird wirecast issue. All right, cool. Well, that is the project. Next week we will have a learn guide and we'll walk through the build assembly and we'll take a look at the code as well. But right now we were just showing off the, some of the features and playing some sounds and things. Yeah, just hyping up. And it looks like you guys are interested. So yay. Good vibes on that one. We'll make sure we'll put extra polish touch on these. Yeah, we really want to make it so that if you've never soldered anything or you've never programmed anything, you can absolutely do this. Yeah, that's the whole goal. Sturgap Python is designed for beginners and Adafruit really prides themselves in beginners first. Right, so I will document it as much as I can to make it an easy build for anyone who's never played with their tronics before. All right, and then general, more comments from Protosonics saying, yeah, this would be great for a sequencer. Yeah, that would be really cool too. Right. And then Remy made a midi cap touch pad with custom PCBs and the MPR 21. That's great. Yes. One-to-one. Yes, we have done something similar. We do that. Really, really cool. That's the updated Stemma version of the MPR. Yeah, this year we're gonna do so many musical projects. If you guys go through the learn guide on just all the midi projects, you can see between John Park and Noel made so many. Yeah, Liz too. Liz, yeah. Really, I think Liz is kinda... Let's go ahead and just include everybody. I think everybody has made one. Sure. All right. And then some comments on, yeah, this is a great gateway to Euro Rack DIY. Yeah, it's happening. It's one of those hobbies that pulls you in. Yeah, for sure. All right, cool. So last week we talked about the fairy wings and it took up the entire show so we can go ahead and look at some of the things we're prototyping and some of the time lapse Tuesdays from the community makes this week. So I guess we'll jump into prototyping stuff. Yeah, go ahead. All right, so lots of talk on the little companion robots and with, I guess, Easter coming up. Oh, that'd be good for like a little egg robot from Zelda Breath of the Wild. Age Calamity, the latest installment of Zelda, the Legend of Zelda video game for Nintendo Switch. So because everybody has to make a cute little baby version of whatever the last thing was. Like the little baby R2-D2, is it R2-D2 or the baby Yoda who can forget baby Yoda. He's right back there. Nintendo, of course, made a guardian robot, the baby version of it. So this is gonna be one of those little egg robots. It's gonna be a shoulder robot. So that it can hang on to your shoulder with some magnets on the bottom. It'll have the little feet dangling and it'll have a servo inside. So it'll just go left and right. Not sure if I'm gonna have the little whistle that goes on top to add some more functionality to that but it'll at least be, what did Lamar say? I think that it's a bitsy inside there with some LEDs, like an LED ring or something to have all the glow that is all around the little cute robot. And it'll just move its head back and forth just like the previous Guardian robot build that Noah did. So just like nice little simple upgrade to that all-inserted python, of course. That's the big thing about that. And then yeah, just a super cute little guardian robot to be on your desk or your shoulder. And then the little whistle. Yeah, it's a nice little way to, I don't know, I guess it's sort of Easter theme because he looks like an egg. He's an egg indeed. But yeah, nice little more servo type projects that we wanted to get into. Yeah, cosplay and cosplay pops and certain pythons, really go hand in hand together. Yeah, we figured since it's one of our most popular videos, definitely got to remake that. And instead of doing the snap together feet, we'll make these chainable this time. And we're more suggested having like a wire to go through there so you can position these and have him be nice little posable little robot. I don't know, other things, I don't know, make it IOT or something. So when you get an email, maybe his light lights up or something, maybe take a look at the mailbox project, the servo inside. So when you get a Gmail, instead of doing the flag going up, and then do a little flute. So a nice little cute project for that. All Infusion 360 was super fun trying to do all of the, what's it called, the form. Sculpt. Sculpt. Nice. That's cool. Well, at least for that. Cool. It's a PLA printed, any supports or anything? No, no supports, no supports. Yeah, everything's at an angle. You can kind of see it there. Extrude that out, which we'll talk about when the project's released, I'll be CAD for it. You're just doing a taper when you extrude on that. This marble PLA filament looks pretty nice. Great for statues and things like that. And then you need a little bit of texture. Yep, it's kinda good. All right, cool. So that is what's being prototyped. Coming soon. Yay. Super cute. Excellent. Baby robot. Sweet. All right, heading over to Shop Talk. So if you are interested in CNC milling and engraving acrylic, I have the tutorial for you. And Pigeon will post the link to the notes. It's called Lair Belaire, engraving CNC. So I went down the radical journey of learning how to create patterned engraving. So I put together this little shit, or kind of a workflow, right? To use the patterns inside the manufacturing workspace to make a fusion 360 to make a nice geometric pattern that can be kind of scaled. So I hadn't done that before. And the original idea was to just download some artwork and then kind of get that infusion, which you can do. And then the issue I came up with that is that I had to pick every single thing. So I came up with a way to use the pattern feature inside the manufacturing workspace to just generate this pattern out of just a couple simple shapes. So I have this little one that I wanted to share which is a piece of acrylic again. And what I ended up doing was engraving some patterns on my three by three midi fighter. So I have here these circles and this is actually the pattern that I show how to create infusion in the manufacturing workspace. And in the bottom here I have these hexagons which is a nice pattern as well. So if you are interested in CNC engraving geometric patterns, I also show how a fail can arise by trying to reduce the machining time. You, if you reduce, if you reduce your clearance too low you'll get some scarred like this. And I talked more about it in depth in the tutorial. But here's another piece of acrylic that's a bit edge lit. So you're trying to do some edge lit engraving and you wanna do some cool patterns. Check out the tutorial. It's about a half an hour or so but I walk you through creating the sketch and then I also show you like some visual ways to kind of get an idea of how your patterns will look like. Yeah, so I hope folks dig it and I will use that as reference for every time I come back to CNC milling and engraving I always have to relearn it but I think doing a library will help out cement it into my brain. So that's why I do those. Yeah, it'd be cool to make this window with that piece. My idea was to create my stock, get my thing and then get the shape. But I wanted to have this piece because it's the only one I have and I wanted to share that before I actually turn it into this. So I'll see how that looks like next week. Maybe it looks good, maybe it doesn't. I don't know. You see how this looks through it. It kind of takes away from the detail, but whatever, we'll see. So that's it, engraving. Good comments on the layer by layer for that. Thanks folks. Cool, all right. And then this, I'm banter on the discord. Link's breakfast quest. Gotta break a few eggs and make a few omelets. Oh, all right. They're just still cooking in Age of Calamity, right? Yeah, I think so. So folks were talking about the Euro rack and Euro rack synth. And I wanted to give a shout out to Liz Clark who put together a case for her Euro racks. And we collaborate on design and she has a video up that shows her process for creating, using a scroll saw to cut the pieces out of wood and just putting it together. The pieces here on the side are laser cut acrylic from Pinoco. So if you've never tried a laser cut service, check out Pinoco. And this is all on GitHub and Thingaversa. So if folks wanna build their own Euro rack case, this is a good insight into doing that. So what I'm gonna do is just kind of show a quick, some quick CAD stuff to kind of show. So the Euro rack is using these Z rails and they are from Tip Top Audio and these are the mounting rails that you can use. They have a nice documentation so you can grab the dimensions to recreate the rail in your CAD software. So I used these dimensions to create the rail. So that's just kind of how we came up as like first let's design the rails. And the way they work, they're a little bit like a T-slot. So there's a center hole and that's what's used to get the side panels. And then you have these M3 square nuts that go inside that railing in that little T-slot and that's what you mount your Euro racks to. So the spacing is very particular. It's 5.08 millimeters. And then there's a length called HP. So like the smallest version is, the smallest length of your rail is 84. So you can just use the user parameters in Fusion to just update how many, how long you'd like it to be. So that's how we kind of put it together. It's a good look at how you can use your parameters to drive your design. So it was really fun to put it together in Fusion and what else do I say about it? We were playing around with creating like a template for Euro rack plates. So I just wanted to kind of test out and see if all the holes lined up and everything. So that's what I got going on here. I think what I'll do as a layer-by-layer is I wanted to show how I created the template. So I referenced this document, the spec sheet from Dofer website and they kind of have a nice breakdown of the dimensions for the mounting holes and they kind of talk about the HP for the module width as well. And then in Fusion, I put together a sketch that's driven with those user parameters so that we can kind of just input a number for the HP width. So in this case, it's like a eight HP width. And again, that spacing is what defines the HP width. Like one HP is 5.08. So if you put 24 or 10 or whatever, it'll just automatically scale, which is really sweet if you're trying to do like something that you maybe want to get an SVG or a DXF and not necessarily a 3D model, you can use Fusion and use a parameter to kind of get that artwork for you so that you can laser cut it, plasma cut it or whatever manufacturing thing you'd like. I just really am into standard mounting holes and like EuroRack is like all about the standard mounting holes, so that's super great. So I think I'm gonna do that as the next layer by layer. So I hope folks like that and they're into their EuroRacks. Adolfo is saying, I've steered clear from EuroRacks to save my wallet, so tempting though. Yeah, well, you know, Liz shows that you don't really need, you can do it on the cheap and that, yeah. Sweet. So yeah, check that out. I have a link to it in the description too. So check it out. All right, I think that's it for Shop Talk. All right, let's go ahead and jump into this week's community, Makes. We got a good amount of them. I think it's this one here. So let's show the time lapse. All right, so I don't know what the deal is with these micro stacks. People are saying that they want some DIN rail, mountable ones. Yeah, so it's a storage solution. I mean, they look really cool. Yeah, I like the assembly of them. Yeah, they're modular storage containers and they have a really sweet assembly. And of course, like the name suggests, they stack right on top of each other. Right. And they have these valuables like a Reservative Pipe Hiko. Their last bit of boards. Yeah. And then they just go right on top in that little wheel there. Locks them in place as it tightens those little ends. Very cool. We'll have the Thingiverse page here. This is by Jake Jake, Jacob. We've printed some of this design before. I really like the color of combos that you can do with these. Right, very cool. Here's like a nice little assembly, and there's a video as well. But just eight pieces, they print separately. It's not printed place, right? So you can assemble this thing and let's take a look at it. This is absolutely right. Miss Certainly Bruce is saying that these need googly eyes. Yeah, they do look like one of those robots from what a battery's not included, huh? Yeah, super cute. Trying to play with it. So using the Rainbow Silk PLA here from everyone, I think. This is the brand. It's either everyone or 3D sell you tech. It's always those two. Yeah, so these right here, lock onto this and push these into here, which have these little holes down at the bottom that unlock it. Push these to get it open. There you go. We like the assembly of these snapped together. So this top lid just pops off from here and you have like a little way to have that being open without going all the way down. So you can slide in like that. So you can leave it open. Nice amount of features. No, that's a cool detail. Very... The aesthetic is really nice. The only change for this was, first the apologies for the time lapse there, I had used the completely wrong profile for it. Oh, really? Yeah, I think that was really strange. Yeah, I had the direct drive profile on there. So it was only like two millimeter retraction. It should have been 6.5. That's why it was all stringy and hairy there. And then the horizontal compensation was a negative point two to have all these pieces fit together, like all the pins and all that. And yeah, just a really cool way to have a nice little storage for what have you. Excellent. Excellent little print here. I really like it. Yeah, you can check it out on Thingiverse. Check that. It's on there. Or at least that's where we found it. Excellent. Cool. And I got a couple more communiques. Yeah, I'm gonna reverse just a little bit and go back to Shop Talk. I do want to call attention to Colt's Three Days. They're celebrating seven years. So check them out. This is a great repo site. It's great to have more. Yeah, it's a curated site. Here's our Instagram site. And they're always sharing really, really awesome designs. Unlike some of the other repo sites, like they really don't have a curation. They've been doing this really, really well. Just a couple dudes. So check them out. If you're a designer and you want to get paid for your STLs, they're one of the best marketplaces to do so. So check it out at Colt's3D.com. And we also gave them a nice test in a minute. So we're gonna check that out. We have a little testimony of some nice things to say. So here you go. Yeah, I want to print out that little phone holder that looks like an elephant. For sure, yeah. All right. Yeah, so back over to community makes. I got a couple of things that came through. I think you'll like them. This one here, giving a huge shout out to Todd Kurt. Todd came up with a really elegant knob, a USB knob. I love this. A bit of a, what would you call it? USB knob, right? Your computer. It uses circuit Python and it's used in the USB HID library. And he shouted me out because he used our CAD models to create this suite, a super stellar design. So you can check out the project on GitHub. There's YouTube video and a nice demos of it. Not just being a USB HID, but also MIDI. So that was really cool to see folks that could also do MIDI and he's like, yes, you can. Very, very cool. And this is a CAD explosion that just. I love how soft this is. This is so cool. So you can see here that the rotary encoder is the knob and that like fits perfectly underneath the pins on the QT Pi, which is a really, really cute circuit Python board. And then the Neopixel ring gets mounted there on top. Super elegant way to create a light up knob. Super cool. And the effect looks great. Does this play like that? So cool. Yeah, you can get a good look at the demo I think in another. It's so clean and cute knob. Yeah, so huge shout out to Todd for tagging me on that one. Super cool. All right. Next up, we have one of the things that we like to do is make tools and rigs for us. And one of them was a tool to make it easier to do heat set inserts. So this is something that I've wanted for a minute and I'm so happy that folks contributed to it. So we ever on Thingiverse made a remix of the heat press. It's really more of like an addition. This here keeps the belt out of the belt. I'm sorry, this keeps the cable from the soldering iron away from getting burnt. So you can see here in this photo, it keeps that away. And it's just a nice little set of brackets that have a little channel here for the cable to kind of fit into and these little snaps that kind of keep it in place. So yeah, it's really great to see. Anytime I need to do heat set inserts, I always pull it out. It's always where I need it to be. And if you're ever find yourself needing one, we have a really nice learn guide that walks you through the assembly. And I'm glad to see folks like adding to it. And that's something that I need to actually, next time I do it, I'm gonna print these out and get my cable set up. So huge shout out to, do we have a thing or verse for posting that remix. All right, we got another one. It's a pretty simple. It's a 3D printed bumper for an Apple TV remote. We just made this just because we made, we needed one. So using Ninja Flex or any TPU flexible style filament, you can use that to create a nearly indestructible bumper for your devices like an Apple TV remote. So that's really nice. This one I'm really excited about. Do you remember the printer mill, Pedro? This is Naomi's printer mill and Max Zilla 2445. 3D printed the Lynx Wood and Sword that Pedro you put together, I think in Tinkercat or something? Or was it Maya? Probably Maya. I don't remember. He printed it on the mill and it's like a perfect model to print in one piece. And it didn't wood it looks like. Yeah, he used wood filament. Came out great on a CR-30. Is the CR-30 the print mill or is this something else? No, I think it is the print mill. Okay, well that's great to see the sword being printed. Oh cool. Yeah, that's great. So it was super fun to see. All right, do the next one. The next one is an iPhone lens holder. So the iPhone 12 Pro Max holder for a 52 millimeter filter. So Pedro, you talking about this? Hey, I know these. Yeah, it's a polarizer for when the sun is shining or having like a bunch of reflections over any object. Like if you're doing like a display and you're getting all these glare. Display, water, like a lot of things like the table like has a lot of reflections. We use this a ton when we're trying to get a nice clean look without any shininess going everywhere. And by shininess, I mean like glare from that's like bouncing off the table. It gives it like this white look that doesn't look pleasing. So this is a very useful thing. And for your iPhone 12 that has three different lenses. This is great that a great solution. I would imagine that this is for a mirrorless lens like a 12 millimeter lens or something. Pro Max, I need this. What do you mean? I need to print this. Oh right, right. This is a remix of your case. Oh, you know what I'm saying? Nice. So good work, Pedro. It looks like a press fit and it has two pieces to it. So it's cool. Very cool. We even have the 52 millimeter lens that we're using now. I think we do, right? So it's fun coming in here not telling you like with the surprise. This is great. I know, right? So shout out to Alexi for posting that in remix up. It's a really useful one. I'm gonna go print that right now. Yeah, I know. We tend to use our iPhones a lot for filming and it's great to release something as simple as a case and then come back as something that's more useful. Okay, this thing holds this. It's adapted. Wow. That's the open source community for you folks. Yeah. All right, we're not done yet, folks. One last one. No, it's not a last one, but this one was posted up on Prusa printers. It's really nice to see other places getting makes but this is the make of the heat set insert and I just love this workshop photo of just like, this looks so good. It's being used. Look how many heat sets are there. It's like, that is why you wanna make one of these. You got a whole slew of heat set inserts to make. This makes it easier, I think. So really, really fun to see this. Not just one, but two photos. Oh yeah, two photos. Looks great. So if you find yourself doing some heat inserts, check it out. Oh man, you see how the cable is dangerously close to the tip. See, that's why you wanna use the other thing. Which is great. So thanks Dave Wilson for posting that up. Very cool. Yeah, all right. And now, for some fun stuff, this one still gets a lot of makes. It's a little planter, right? Themed after the Mario Buu from Super Mario Brothers and this one just looks really nice. So Zoom24 on Thingiverse posted this up with their succulent. And a lot of makes, though. You should probably do a time lapse of that, huh? Yeah, maybe. Looks great. All right, I think maybe one more. Two more, sorry. Almost there, this one's a really good one, too. So it's a unicorn horn. This is super cool. I'll just read it from Chris on Twitter. Said they made their horse a light-up unicorn horn for Valentine's Day. Had the idea for ages. It's using the Adafruit NRM 52 840 Feather. This you can control a little bit of Bluetooth, 12-volt NeoPixels, I suppose. I had not seen those. And then the horn is from Adafruit's Thingiverse. This is great. Oh, cool. This is so cool. And we wanted to do this ages ago as well. Yeah. Don't have access to a horse anymore. Not anymore, yeah. But this is so sweet. This is just the coolest. And of course, they won whatever competition. You cannot win with a unicorn horn. That's so awesome. A lot of pleasure in seeing the unicorn horn just make the rounds. So cool. If folks want to learn how to design, how I designed it, you can check out my Lair Biller. Sorry. Yeah. OK. The next one is the last one. We're just catching up here with all the community mates. So this one was a sort of a wine holder for Valentine's Day. Honey and milk. There you go. You can use this. Remix it, modify it. I think it's in Spanish. Filimento, Prusmit, Pilegold. Yeah, very, very cool. Grazie, yeah, maybe it's Italian, not Spanish, sorry. But yeah, this is something we did a couple of years ago. Seven years ago. The 48 fruit. Yeah. We just carried it over from our stuff because we thought folks would like it. So there you go. That's all of this week's community mates. Huge shout out to everybody posting their stuff. It's super informational to see. And yeah. And then a question from Bruce. Have you had any issues with the heat insert tool? I've heard from folks that invert the iron for prolonged length of time, have burnt parts of it out. Heat dissipating back into the handle. Yeah, you're going to want to definitely don't leave it on and turn it off when it's idle. Yeah, that could definitely be a thing. I haven't had any issues yet, but I don't use it any longer than like a half hour. So maybe that's what's going on. But yeah, that's definitely also printed in the ABS or a PETG. Yeah. Yep, let's see. And then just general comments on people liking the Pico MIDI fighter. And yeah. All right. We'll see you guys later tonight. Do we have a show and tell stream going on? It happens every Wednesday at 7.30 p.m. If you'd like to be invited or you'd just like to join, rather, you can go to Discord. And PT will post the link to StreamYard so folks can join in five minutes before the show. So something about that somewhere around there. Sometimes 10 minutes before. But 7.30 p.m. is when it starts and goes live. And then at 8 p.m. is Ask an Engineer, a full hour of Lamar and Phil talking about open source hardware, new products in the shop, news, and more. And then on Thursday, we got John Park's workshop. Every Thursday at 4 p.m. Eastern time. Scott's doing a deep dive on Fridays. Every Friday at 2 p.m. On Sundays, Desk of Lady Ada with the special segment of the Great Search with Digikey. Tuesdays is JP's product pick of the week. Every Tuesday at 4 p.m. Eastern time. And then it loops right back around to three hangouts. 11 a.m. Thank you guys so much for joining us. I really appreciate it. Everybody having fun? Where's my pico? Here's my piques. I think you'll play us out now. We'll take a little, we'll take a look at this. You know what I'm playing. Probably all show next week. Yeah, and I really want to showcase like setting up a drum kick, so I think that's fun. Oh, yeah. Keep practicing to come up with something. All right, folks. We'll see you guys next time. Until then. See you later tonight. Yeah.
