 Hey, what's up, folks? Welcome back to another 3D Hangouts. My name is Noah Averwies. I'm a designer here at Adafruit. I do them every week. I'm brother Pedro Averwies. Good morning, everybody. Pedro has creative tech here at Adafruit. And every week we're here to share three different projects featuring electronics from Adafruit and delicious cups of coffee. Yes. That's right. This is a show we combine 3D printing and DIY electronics to make inspirational projects. Hello, everybody. Welcome back to the show. Welcome to episode 300, no, 413. Today is September 13th, 2013, 2023. Wow, I'm way off. And we welcome everybody to the show. We're hanging out in all the chats. Facebook in, whatever in is, LinkedIn, YouTube, Twitch and Twitter formerly known as X, formerly known as Twitter. I'm rusty for some reason. X is pronounced like a sh, g, g. Yeah, we're also on Discord. Let me bring that up. That's not, give me a second. I have the, oh man. I'm right here. I'm right here. All right, you got it. Great, thanks. Tell everybody hello on Discord. Good morning, everybody hanging out. We are giving shout outs to everyone hanging out in the chat. We got DeWester, Paul Cutler, Squid.Jpeg, Cup of Coffee, my favorite name. Coffee, yeah. Roslyn. Cup of Coffee, Mark. Three Ricks, three R-I-X-X-X on YouTube. Just hanging out like you said on the Twitch, Periscope and Instagram, not Instagram. LinkedIn, hanging out all over the world. Hello, hello. We'll give you more shout outs as we get through the show. Feel free to add any comments, questions, all that in the Discord and the other channels. Hello, we'll go ahead and kick it off with the housekeeping stuff we do every morning, every morning, every beginning of the show. Let's take a look. We got new stuff on the Adafruit.com slash free page. If you spend more money with Adafruit, you're gonna get some freebies. Let's go through the orders, the tiers. If your order is $99 or more, you get a free PCB coaster with the golden Adafruit logo. If your order is $149 or more, you'll get the PCB coaster plus an Adafruit KB2040.

So if you wanna pick up some stuff, support the show, support the many awesome people sponsored by Adafruit. Use the coupon code to Tombstone. All right. And that brings us to the show. We have this week's project. Have a little bit of prototyping further into the future or into the past, depending on what you think of the future. We have some shop talk. We have community makes and a time-out of Tuesday. Let's take care of some more housekeeping stuff. Just gonna email from a PT. There will be no ask an engineer. Oh, that's just it. Yeah, we got some remote folks in. So we're taking care of them and some other stuff going around in the office. So just show and tell. I believe with either Liz or JP, but ask an engineer will be back next week. Yeah, real time. Yeah, real time. We literally just got it. All right, cool. So let's go ahead and jump into this week's project. This week's project is an interactive Tombstone. Whoa, double me. Yep, double you. I couldn't hear you. I had to bring you back in. If you wanted to do a full screen, we'll just do this. Oh, was it the microphone? No, it's when you isolate the thing or when you remove yourself, you can't hear that audio. So you just have to click on the full screen button. Oh, gotcha. Okay, so yeah. So this is an update to last year's Matrix Tombstone. So one of the updates on it is that we're having it run a prop maker, RP2040. So it can run the Matrix and the Servo and LEDs as well as a time of flight sensor. This is the L35L4CD distance sensor. Of course, coded by the very awesome Liz. So you did a great job doing it. Some inner activity. So as soon as you walk up close to it, sensors hidden right between his legs right here, it'll sense and it'll trigger the crow, raven bird. So triggers the bird to go off and then there is a speaker in the back but because it's so loud, I disconnected it. So we have that one, we have the Matrix display going. So a lot of cool stuff that's being run all by the prop maker, RP2040. Wow, yeah, it's a fully featured Tombstone this year. That's a lot. Did you mention Neopixels? Like Neopixels sound. There's Neopixels or sounds. So there's Neopixels inside of the Styrofoam Tombstone and then as well as the raven bird guy. Raven bird guy. Right here, yeah. Kind of see the LEDs in there. So it flashes red and green. That does a nice little pulse. I remove his head. You can see how that's all mounted. There's the LEDs right there. And then we have a nice little servo horn made out of some foam core. That's great. So that just slips on like that. Of course, we had to make it super creepy with having it turn 180 degrees. So nice little creepy effect. Nicely hidden, everything connects to the back of Tombstone and quick look at what that looks like. So we flip this around. You can see how everything is in set. So I use a wire foam cutter to build all of the little component recesses. So everything just press fits in. This is a pretty thick foam core or foam Tombstone. So we had plenty of room to make like recesses for the matrix. Goes in like that. It's nicely framed out and then all the wiring and then you even have little spaces for even create these little covers made out of just foam core, that solid components in place. So everything is a nice little crafty construction. The only three printing that we had to do was for the bird which of course you can just find one of the hollowing decoration birds. But of course it does have to be hollowed out so you can add the electronics in there. So that's the reason why I printed it. And yeah, this is a, I think, I believe it's a fairly common Tombstone at Spirit Halloween. So we got lucky. Think this was a model from last year. So they did a really good job of mass producing these. It's only like 25 bucks. So definitely affordable for having these as decorations. And yeah, very easy to work with. I'm just using a wire cutter to make all of the cutouts for it. And yeah, what else we can say about that guy? Yeah, I like the Tombstone. It's a really big Tombstone for 25 bucks. Yeah, it's interesting. StarFoam is relatively easy to work with so you can cut your channels out. You picked a really good one because it has a lot of space. It's like the perfect size for the display. It's a 32 by 64 RGB LED display with the four millimeter pitch. So it's like the biggest display you can get. So it fits perfectly in there. Piece of black acrylic diffuses it but the code is written so you can update the text. You can update the color. You can update the speed of the text scrolling. You only get one font, I think. It's kind of like a default font but you could do some extra code and like make a bitmap scroll through or something like that. That'd be nice. But yeah, you can have full graphics if you want. We just wanted to stick with the simplicity of display IO. So you can do whatever text. I think for an example, we used to be like a lot of folks here in the States, they like to do like a candy bowl with like a cardboard and a Sharpie text that says like just take one please be considerate. Now you can have it say that and scare the people be like, I'm watching you, please take one or I will haunt you. You can get real creative with this type of project and modify it. It doesn't have to be a tombstone. It could be anything. It doesn't have to be a crow. It could be anything that you want it to spin. Maybe you can have something pop out when a person gets near it. So we think it's a really good kind of all around interactive piece for your Halloween font. Yeah, all the pieces there to completely customize it like you were said with different like triggers for the servo and then code wise, you can add more stuff on there. Like you were saying, if the sensors triggered, you can have the text change around. That's something you'd have to add on there. It's not the default code, but all the libraries and everything is there for you to go ahead and add any of that. One of the other ideas that we had, of course, after we're done with it is one of the other triggers that would be cool is if the relay could trigger setting off one of the fog machines. So a little bit more of interactivity. You can definitely add more like LEDs to stuff. So everything can be like a scene, like a little graveyard scene can be powered by just these two boards. Yeah, I just had an idea. If you want to get really mechanical and clever, you could use the servo to actually dispense candy so you can open a door to let candy fall out of something. So you can have all these elements, the neopixels, the text and the display. The sound effects can be customized, whatever. It's a good idea. A lot of cool stuff, yeah. So it's pretty cool. It's funny how the ideas flow out after you've already seen it. Yeah, after you've seen it. Yeah, like the initial project. Yeah, but that's the point of these projects is to have a start on the plane, like what's a minimal viable, not too complicated to build and reproduce. So it's definitely easy to build, reproduce. Yeah, you might have some of these parts already. So definitely consider maybe reusing them or retrofitting something like we did here. So, Pedro, you got the learn guide this week. You put it together and shout out to Liz, of course, for coming up with the code page and really working with us to make the code happen. Yeah, tell us about the learn guide. Yeah, so a quick little synopsis on the learn guide, what it does, the interactivity with Tombstone and of course the hero in this are the boards, the prop maker RP2040 and the RGB matrix feather wing. So the sandwich right on top of each other. And then it goes directly into the matrix display. This was Lamar's idea. We weren't originally going to have an RGB display, but Lamar's like, why don't you add that to show that folks can have feather wings with the prop maker feather? And it was like, oh yeah, of course, of course, we can do this. We have really good display IO library support for working with an RGB matrix. Just about any of them in the Adafruit shop will work. It's easy to set it up, you can see in the code. But yeah, it's a really good add-on to a prop to have this really nice display that has RGB LEDs. And it's relatively big. You could chain them together. But for this one, we just needed one because it's big enough. Yeah, you're right. I mentioned that, that you could chain these together and have, like we were saying, having a whole graveyard scene of multiple things all being run by one board. Yeah, yeah. All right. Parts, parts, parts. Yep, just a synopsis of that, showing like how everything is embedded. And then of course the parts. We are restocking the prop maker soon. We've got the feather wing kit, the 64 by 32 matrix display. Using the four millimeter pitch. The VL53L4CD time-of-flight distance sensor, which is all STEMMA, so that just plugs right in. Speaker and some of the button Neopixels. Nice little small PCB ones that'll fit inside, almost anything. Yeah, this is great. Power this entire circuit. We're using the five volt four amp switching power display. Power supply, yeah. The black LED diffusion acrylic panel, the one labeled here is already cut for you. We do have like a square size, if you want to do some custom cuts for that. Like if you want to combine them together, I guess. The microservo is just as cheapo SG-92 servo. It's standard servo, yeah. It's standard servo for extension cable so you can easily disconnect and reconnect things, especially for storing away after the holidays. We're using the two pin plug headers, the socket headers, the three pin socket and the three pin plugs. So this is gonna be for your speakers. So you can easily disconnect the speaker. The three pin will be for the LEDs and the servo. And then the silicone coated ribbon cable. You can have a nice bit of flexibility with your components. And then the conduits, wire conduits, the split loom tubing. So it's so you can easily hide all of the cables that are coming out of the bird. And then the gargoyle tombstone is in stock. You can just buy it online. But these, I've seen them at all of the spirit locations in the little tombstone section area. And like I was saying, yeah, it's like, you know, 25 bucks. And yeah, 24, 99. Three and a half feet. Yeah, this is what it originally looked like or what it looks like before you go in there. And it is so maker friendly. Like you were saying in the intro, look at all this space that you have to work with. And this is the thing that caught my eye when I was looking for something, doesn't like you said it doesn't have to be a grave stone or a tombstone, just something where you can, you know, have this area to play with. And that might have been the intention where you can go in there and carve in your own name and text and all that. Yeah. There are a couple of different tombstones that are in that way. You can just chop off some of the default text that's already in there. I think the other one that I got was... The rest of the piece can look cool. Yeah, that way you can have like a portrait view of it. Exactly. You could really go crazy and like make it look like a portal, like it animates and, you know, I think we have some sort of bitmap sprite sheet support, which we actually did that last year. Yeah, yeah. You could combine maybe those codes to have maybe a bitmap sprite sheet play depending on... And I got another idea. Like you just keep coming. I know, they just come when... It's the time of flight sensor knows exactly how far away something is. So you can specifically say the closer you are, the different thing you get, the brighter it gets, the louder it gets, further away, you know, you can adjust it on that. So you can have different tiers of closeness, of distance, because it's not just like your cheapo run of the mill PIR sensor, you know, proximity sensor. Like this thing knows how far you are. So you can display all sorts of fun stuff. You can even display how far you are. Yeah, it could be like you are 10 feet away, you are 12 feet away. Oh man. It's super good at the end. Yeah, so here's the last year. So you can see here, you can have like really good kind of GIF animation style animations with the RGB displayed. That's a if you need any more additional ideas for construction of this, here is another one. But this is using the pipe, the matrix portal. So this would be just one single board. I don't think you'd be able to run all of this stuff, right? Yeah, I don't know if it has the way they call it, like the amp isn't built in. So if you want to, you know, you got to think about that. So depending on what you want, we have all sorts of different boards to do this, but the prop maker combined with the matrix or other wing is really what this one was about. Yeah. Really showing the power that you can plug in all these components and still play your wanted features for it. Tim and in the circuit diagram, it's pretty easy, everything because of the terminal blocks just plugs right in. Yeah. It is such a pleasure to use these with those quick socket and plug disconnects as well. Yeah. Aiding in like distancing. So you can disconnect it closer to the, all of the components. So you don't have like these long cables that you have to store along with it. So the speaker, the NeoPixels are sharing the NeoPixel ports on there, our terminal spots. The servo plugs right in and there's headers already on the board that you plug into. And then the time of flight sensor is STEMMA. So that just plugs in as well. And this little pretty easy little detail on how all that works. Liz did an excellent job of writing all the code and sort of splitting it all up. So you can get in detailed. This is how to install your circuit Python. You get the board, definitely want to get the latest. Usually when these come in, it's like in Arduino. So you want to get circuit Python installed on there. Nope. Moving on over to the code. Nice little breakdown of how everything is working if you scroll down. But this is the whole chunk of the code which of course you can just get the project bundle. You click on this button. I'll download all of the sound effects that are used in the project that you can swap out and then just easily change out the names from I think in here. Yep. And then the servo, like how you want those to go, like the brightness, how many NeoPixels are going on in there. The audio level for it. The distance for it to trigger. Yep. The color for your text. A bunch of editable parameters that are nicely commented in there. Like we were saying, all the breaking everything down for all the specifics, like the matrix for the sound effects, how that's being triggered. The pixel servo, the excellent job on having all that spelled out. See, moving on to three printing. Like we were saying before, this is just a bird that's hollowed out. Shoutouts to, it was Damian. Let's see, this is a remix of one of his birds here. So all I did was take it inside of Mesh Mixer and hollow out the entire body because he, I don't think this one was hollowed out. No, it wasn't, oh no, did he? Yeah. Maybe this version too. Yeah, he didn't upload the hollowed one but we have it on the Adafruit Thingiverse profile and it's linked as a remix. So we're gonna find that. So you can get the skidded off of ours. It's like three shells, so nice and light so the servo won't have trouble moving the head. And then no supports, everything just. Oh, that's nice. Yeah, just get a brim to hold everything together because it is all hollowed out. So it was the body and then I did hollow out the eyes as well so the LEDs will shine through. That's basically it. Like we were saying before, you can just get like a crow from Spirit as well, try to use that. See, moving on to the assembly of that, the very first step that I wanna point out. This is a little bit of tape cover from the Distance Sensor. I was getting some weird readings with the Kapton tape being on there, like the audio would just keep looping over and over. The very first step is remove the tape cover. Yeah, yeah, it doesn't see through the tape. Yeah, the tape is very protective. Yeah, maybe it helps with picking and placing, like it lets you suck in. It's definitely something for a transfer to keep in it, you know, so it doesn't get scratched or whatever. No, let's see, moving on to the power cable for the matrix, I did have to shorten this out and the way that it comes, there's like two of these plugs together. I just cut the other one off. That's if you're going to daisy chain them together. So we'll be using this. I wanted to make sure that all the wiring was nice and neat. So I just shorten that, make sure you measure the distance. It's gonna be required when you plug in your feather wing. And then the assembly for that here is how you plug in together. The feather is gonna have the socket headers on the bottom and then on the RGB feather wing, I'll have the pin headers pointing up, a little sandwiched together. And then the Hub 75, the included plugs to go onto the matrix displays, you have either a socket or a plug. You wanna use the socket version, so that goes directly into the Hub 75 matrix display. So that's how that'll plug in. Yeah, it's like acting as a mount too. So no need for screwing in the board anywhere, just uses the socket as a means of mounting, which is really clean. Like this is a really clean build. I like that you reduce the cable and shorned it up. Like it looks really clean. There is some soldering required in that part, but if you splice wires, you're gonna have to do that. I think you should do this just to kind of keep it. The other option is you could like coil things around and this is the frame for the PCB. There is a little bit of gap in here, so you can insert wires in like in between this, the PCB and this frame and sort of coil your wires and have some sort of, haven't tucked and be neat that way. That's the other option if you don't wanna cut them, but then after a while, you will run out of that gap room. Yep. Are you keeping an eye on the discord, anybody? Yeah, nobody's said anything. Just a good morning to DJ Devin and Yanni school. Johnny as well, just saying hello. Okay, I'm seeing like spanny stuff that might be coming from somewhere else. Oh, it's YouTube, of course. So you're going on to... Yeah, so we're using the wire form cutter to cut out a display. I did upload a template that you can 2D print out, tape on to your thumb core and then trace it out. Yeah, that's actually handy. Yeah, super handy, cause I had to build it to make sure, cause there's no, you gotta cut, measure three times and then cut once. Yeah. There's no way to... I didn't wanna go out and get another thing messed up. So there's a stroke around the outline for the frame. The outline for the frame, the outer outline will be the size of the entire width of the display. The inner stroke is so you can create this recess so that, you know, it can just plop in without going all the way through. So you have this like nice little framing that will be made out of the foam. I'm trying to scroll in the wrong window here. Then we're using the blackility acrylic. We're using the pre-cut one. That'll get inserted first. The matrix display goes next. So it'll be nicely diffused. I'm moving on to building the eyes. Just measure the distance between whatever, wherever you wanna put the eyes in. And we're using this cable here that is a three, has like three wires coming out of it, but it's bundled into this. I think it's like a 20, 28 gauge cable wire. Is it an extension cable that you cut? Or just? No, this is just a custom one you can find on Amazon. Oh, that's nice. Yeah, so I have a three pin one and I have a four pin one. Where is it? I don't have to use so much ribbon cable. Right. Yeah, and it's nicely insulated. The ribbon cable I use just for the LED so you can have a nice amount of flexibility when mounting these. Then the rest of the extension is using this, you know, the regular plastic it's made out of. And then we're just using the cutting out where we want the eyes and then one for the mouth where the speaker is going to go into. You can see this, I'm just, I added the way it looks all like curvy like that is because I'm adding the strain relief for the cable is built in to the way that you cut out your recess for the wire. So just keep that in mind. You have that built in towards being mounted. Same thing with the sensors, just do your little cutout. And then we're doing a little cover for that as well. Just using, again, just crafting pencil and paper drawing out where things are then cutting it out. That extends to even building the servo horn. I could have gone into a fusion and spent all this time modeling stuff or I could just literally put the servo down with a pencil and then trace it out the shape that I want. So this shape is just the neck shape. So I just put the body down, trace out the neck, cut it in half and then use the little bits of leftover foam core to create this little horn that'll fit the head. Yeah. Yeah, that's a really good material to work with. It's a bit spongy so it can conform. It's forgiving and it takes no time to print. So this is like the black coated poster board on core board. So the foam core on the inside is nice and black as well. So I just want to point that out as an option because I didn't want to sit there and spray paint, you know, add another additional step. And when you're cutting out your servo little insert thing, make sure to cut out one for the wire as well because that's what this little extension thing is there. And that is where we're going to, what is he moving to the top? And that is where that is going to mount. Whoa, what happened? Render. Reload, reload. See. Uh-oh. No. I can see if I can load it. There we go, wait. Okay, you got it? No. The internet's not down because... There you go. Okay, there we go. All right, so that mounts in like so the ladies get press fit in there as well. So I'm just making little circular cuts that'll allow it to press fit in. Oh, come on, Safari. Too many windows. Did you do the guide? I got it. Where are we at? Silverhorn? Silverhorn, yeah, right near the bottom. All right, so we got it, we got it put together. Let's see. Okay, so yeah, the wires have come out of the back and that is where we're using our socket and plug extension cable so we can easily disconnect that. So when we want to sort this away, the bird doesn't have all these wires dangling down by the tail. Scroll down a little bit. Here is where we're cleaning everything up with the cable conduits. Oh man, I think you got these like it. When you were working at CompUSA, all of the years ago, dude, we finally took all of the conduits. We used all of it? Yeah, almost all of it. I think we still had a big old piece left but that was the very last, you know. Yeah, it's good material, even for like cosplaying, like kind of has like this Morgue Star Trek kind of look to it, but it's black. So if it blends in at night, I didn't even notice like you don't even need like the full tail of the raven slash crow. I know, and I was sitting there going, oh yeah, I need to cut a hole out of this tail and I'm like, wait a minute, the camera's like, yeah, it's never focused on it. It's never really focused on the bird's body, yeah. So that's good. So that's what makes conduit great. Definitely use some for hiding cables and keeping them bundled. Yeah, definitely take inspiration by what was it that animatronic at Spaceship Earth where they just turned the kids head around because his face is missing. Oh, that's funny. Let's see, yep, so that plugs in and then if you scroll down every last step, you plug everything into the terminal connections, which makes it again, such a pleasure. Yeah, that's the whole thing about the Prom Maker. So the Servo has the pins, you just plug it in. The Stemacutee port is like standard now across all feathers. So that makes it super easy to plug in an I-squared C component. Yeah, man. So the, you know, the barrel jack plugs in for power and it powers the feather too, right? Like you don't need two power supplies, it's just one power supply plugs into the wall. So you have all day, whenever it plugs into the power in the house, that's great. And then as, since we're talking about the power too, one of the things for outside use, I just wanted to point this out since this is how we were filming the Jackery, these guys. Yeah, it's a nice big battery. So yeah, it's enough amps or voltage or whatever it needs to power. I did try hooking up the fog machine. I think it'll work. It just, it takes a while for it to heat up. So I wasn't sure if it was actually working or not. And I didn't need to get the shot. So I just plugged it into the wall. So I think you could run a fog machine off of there too. Cool. Yeah. There's all sorts of batteries like that now these days. It's cool. All right. And I think that is it. All of the files are uploaded because they're to get. Yeah. Oh yeah. We got plenty of time till Halloween. Yeah, I was thinking about it now because Halloween comes so quick every year. Oh yeah. Yeah, we're really on time here. Normally we would release something like the first week of October, but I'm glad we're doing it right in September. Like all the crafts, all those craft stores are already stocked up with their Halloween stuff. Get to it now before, because once it becomes October, all the Christmas stuff comes out. Cause that's just the way the cycle works here in the department stores. But hey, it's nice that you can get the thing online if you want to get this exact tombstone, but you're free to go. But you probably have a spirit in whatever, you know, shopping area that's close by to your house. Yeah, the meme, the kind of classic meme is that like any store that shuts down becomes a spirit Halloween. Pretty funny. Like it's what happens. Even in the most fanciful places here in Massachusetts, we have this thing called the Patriots Place next to Gillette Stadium. And they have a, they have a banked store that became a spirit Halloween. Super fancy. It was like, okay, cool. And there's a lot of money to be made in this Halloween culture. So not surprised. Okay. You got a comment here from Mike Jones on YouTube. Says the fog machines are like heaters. Yes. Way too much energy for a battery pack. Maybe the lowest powered ones, but not for long. Yeah, I know. Again, it took a while for the fog machine to heat up. So I don't know if it would actually work or not on it. Right. Maybe one of those humidifiers, but they don't cause, they don't create enough fog. Yeah. Yeah. Humidify them. I'll try it out. I'll try it out. Just because we don't want to, for Halloween, I don't want to run all this extension cable out there. Right. Okay. Yeah. Just be careful. Like there's no weathering really here. Weatherproofing. My God, you're right. Yeah. Be careful. Obviously, I will say it, like it's been raining a lot here up in Massachusetts, but also across the States. Yeah. Make sure your sprinklers are turned off. Yeah. Yeah, turn off your sprinklers, yeah. But I mean, that's an indoor thing for an indoor hunt. Perfect. You don't have to worry about weathering too much. Mm-hmm. Yeah. So it's all good stuff. The other safety concern is cutting the styrofoam. Make sure you're outside. Oh gosh. Please wear your mask. I had hands all over me and I still got like, I could still smell it and did not feel the best. To finish it. I used those COVID masks to use, like bring this out. I should have used the mask, you know? Yeah. What I figured, because I was outside, you know, I had three, four fans blowing on me. Yeah, styrofoam is nasty, so just keep that in mind. It's not good. Yeah. But you can get wire cutters from Amazon or craft stores. Yeah, we were thinking, I don't know if you could use an X-Acto. It might like, just because of the way that the texture for the foam is, you know, it might like break off in little bits, but I don't know. Yeah. To check into Discord, we got some updates from DJ Devin. He's got, how many of these? One, two, three, four, five, six, seven, eight, nine displays. That's a lot. Holy moly. But hey, I like his 3D print brackets. That's a really good way to kind of utilize the M3 heat sets that are built into the frame. Really good use of them. That's a good. That's a really good idea. That's the most I've ever seen the outside of like an arcade. I was about to say, yeah, I was at which arcade and the display is just this ginormous freaking panels of matrix is all. Yeah, I think it's Pac-Man or something. It was Pac-Man and some other game that they had on there. It was massive. It looks so good too. It like totally fits the arcade retro theme for it. Displays like this. Devin, the whole, he's got a comment on like the audio recordings from the Gargoyle project or Tombstone. So those were, I did those recordings and I just, you know, lowered my pitch in like whatever software. It's supposed to be the word I smell children, the phrase. That's actually from the PG movie, Hocus Pocus, you know? Bedmiddler. She's like, I smell children. Maybe it's Bedmiddler. Some of us, somebody says she smells children. So that's where I got that from. You know, it is a little concerning, but that's where the reference comes from, a very Disney movie, you know? So he's joking around now. Oh, okay. What else? Yeah, it's one of those cliches. Oh, that's funny. The Raven sounds like it's like a real bird when it's moving. Yeah, kind of. Yeah, the cable, oh yeah, you didn't notice the cable out of the tail until like the video pointed out. Yep. Yeah, it's never too early for Halloween. And there's some brackets here from Johnny on printables. That's great. Thank you for sharing that. Yeah, we'll check it out. We'll put on the blog too, because that's a really useful thing to have brackets, especially like universal ones. Oh dude, I should have made one for this one. Yeah, some feet. Of course I ran out of time. Yeah, I mean, where the stakes go, you can see what's actually holding it. It's your storm, what was the name of the hammer? Goom hammer, yeah. Okay, you could definitely add some three-printed feet for that. Yeah, for sure. It comes with stakes, I think, to like stake into the grass or whatever. But yeah, some feet would be nice. Yeah. But you can always use like an L-bracket and made out of metal and just like kind of bolted because you can just drill right into the styrofoam. I mean, I already have the holes. I would attach it to the stakes that are on there. That's so cool. So yeah. Nine matrices, well, using the Pi Portal S3, that's super cool. Yeah, yeah, so we'll see it tonight. And another Devon's Brackets are also unprintable, so yeah, we'll share those definitely for tomorrow. Thank you for sharing this. Very cool. Oh yeah, that's a really good idea. Mike Jones on YouTube, it'd be cool to have somebody to recognize in AI. Maybe then the Tombstone could talk to you. Yeah, that's more like a Pi. I think I have a Pi project because it has all the power to do that, but it's still a really cool idea. Maybe that'll be the update for next year. Yeah, next year we're just gonna keep making these Tombstones. Yeah, cool. All right, let's move on to prototyping. Yeah, we're gonna prototype next. All right, let's go ahead and jump into this week's prototypes. All right, cool. I'm gonna have to stop my screen. So the guitar will be next week's project. It's Synth.io circuit Python 3D printed guitar synth. Actually Liz has it and she's finalized the code for it right now. But yeah, we're gonna talk about it next week. But in the meantime, I wanted to share an updated project that we're doing. It's a collab project with Phil B. You might remember this. Let me see if I can share my screen. We gotta get the new screen share up here. I'm gonna share my whole screen. And we're gonna go in tunnel mu for a little bit, but then we're in CAD mode. So this Fusion 360, it's my CAD choice. This is Hal 9000 from the movie 2001, Space Odyssey from Stanley Kubic. This was a learn guide prop that Phil B. did I think in like 2012 or something like that. We have a learn guide for it. But it uses some very legacy Arduino wave shield. Yeah, so we wanna update this for the prop maker feather RP2040. So I'm coming up with this three piece enclosure. It's using these massive 100 millimeter arcade buttons that have built in LED. And then this nice eight ohm speaker. And then of course the prop maker. So I got the prop maker here. And it's just a cool prop that you press the button and it'll play some samples from the movie 2001, Space Odyssey. So I'm coming up with that. It'll be a fairly easy project because it's just like, you know, everything gets wired in here. I think just a little bit of soldering on the button, but I'm coming up with a way to kind of make this giant, it's not super big, but it's bigger than my printer's print value. So I had to split it up into three parts. And I think we'll use like an inkjet printer to make the sticker. And yeah, I got a speaker grill. The original project from Philby uses laser cut parts. But now these days you're more likely to, makers are more likely to have a 3D printer than a laser. So it was Philby's idea to kind of like go back and look at some of his classic props and see how we can revise those using the new prop maker feather. So that is what we're gonna do. It'll probably be wall powered. I don't know, there's plenty of room for battery, but I think we'll have it plugged into the wall. I have a little USB-C hole here. But as you saw on the back there, these three pieces will be bolted together with M3 screws and hex nuts. This thing gets panel mounted, you know, the button. It's a big button, but it's also, you know, it looks just like the HAL-I lens or whatever. So that's what I'm working with. It's not like super screen accurate, mainly like the speaker, but I think it's good enough. I like the proportions are good enough. And that's what I'm working on. I have some components here. Let's get into that. And we'll look at my overhead here. Let me present an extra camera. Use my camera camera and bring that in. So these are the 100 millimeter buttons. It already looks like HAL. I'll probably re-print this in silver or painted or something, but it's basically a giant arcade button. It's got a big chunk to it. You can see here kind of how it's actuating this micro switch. It's super maker-friendly. Like this comes out, there's the LED. This has like a spring here, and then this can come out here. If you wanna like completely change the bezel or anything, you can print it as well. But it's really nice. Yeah, I think all you need is the bezel, just press fit right on top. Right, so I'll probably be printing this. It comes with a big space. But then you gotta take all the shit. Yeah, I'm in an apartment and it's a little bit hard for me to kind of spray paint. I don't want to, yeah, even with space, I don't want to spray. So I'll probably just re-print it and then keep this internal part and then use this piece here. But yeah, it's the micro switch. You could probably use those quick connects for this, actually. That way I'm like saving. Yeah, and then it just has built-in LED. I think it has a built-in resistor, I'll see. But if not, you can add one, it's fine. But yeah, this is the main piece. This here is kind of hard to print. So that's why we got a nice button for that. It's just the right size for Hal and I. And then this is the speaker. I just got these parts in today. So it's a nice eight ohm, one watt speaker. So plenty of oomph. You got your mounting holes here that are M3, M4 size. And yeah, so I got my parts. And I'll start working on that after the guitar synth project. So that'll be a fun one. And it's an all-around fun. Like you press the button and it randomizes the audio so you can make a nice kind of big Mac sound box kind of thing for the kids or whatever project. Yeah, good idea from DeWester saying, he thinks his Nest doorbell just got redesigned. Oh, that's fun. There you go. It'll be like a costume for your doorbell. Sure. You thought what was real for a second? Oh, I'm thinking the Doctor Strange thingy here. I saw that cast connections, the POV. It's just right for it or two strips of the tiny little, and there's some new pixels. They're spinning. It spins. Yeah, it's just on a little motor that spins. Yeah, yeah, that'd be cool to kind of redo or to use somehow. Probably use for making one. It'd be cool to make a big one, because this one's like the size of your palm. Yeah. So it looks really cool though. Okay. All right, before I move on, if you wanna pick up any of the parts that we talked about, you can use the coupon code TOOMSTONE and get 10% off your order. I don't know. We didn't post any of the links, so we usually do. That's fine. The fritzing stuff. Got like lists. Dang it. That's fine. All right, go ahead and move on to this week's Community Makes. Yeah, we'll start with Time Lapse Tuesday video. Yeah, this week's Community Makes was a backup time lapse. Oops, am I muted? No, you're good. Oh, I have a little message here saying that. I muted the video. Oh, okay. I'm not muted. Just so it doesn't have the music. Yeah, so this week is a lightsaber pull noodle handle. Yeah, or sword, whatever kind of sword. I think it's what it's supposed to be. And this was a backup time lapse because the printer here that we used for doing the time lapse had a catastrophic clog where you have to disassemble the entire thing, like all the way down to the heat set and take out the nozzle and the internal PETF tube that's inside right next to the nozzle. So luckily I already had this one printed out. It was supposed to come out when we did the lightsaber project, but what got bumped out up instead. But it's a nice little handle. It has these little threads that fit these smaller pull noodles. This one's definitely not for a pull since the little LED and all that stuff is exposed right there. There's a little button to print it on and off. But this is supposed to be for the smaller diameter pull noodles that they have at the dollar shops. And that just screws right in like that. There is two of them, but because I thought I wasn't gonna use this project, both the kids have it and I don't know what the other one is. That's funny. I was surprised I even found this. I've seen different versions of this. I saw one that was like a classic Hilt from Star Wars, but this was like a more, kind of like, I don't know, English style, kind of, you know, what would you call it? Like medieval or something, style. Yeah, a little handle on it. I didn't know that pull noodles had different sizes. They have like a smaller version. Yeah, they have better ones. They have bigger ones. I think the, I used off all the big ones for like the planter pots. Oh, that's funny. Elevate the plants out. Yeah. Sort of using all that soil. But yeah, this is the smaller pull noodles. Well, it's kind of still summer out. Right. I didn't get the kids to beat each other up with these. That's funny. This one, obviously not the LED ones. Right. That's an excellent little print, though. All right. I'm going to share the model. There's a bunch of different ways or models that can utilize the pull noodle. Such a versatile material here. Yeah. Yeah, it's a paid model. It's a $1.75, but scroll down a little bit. You can see like these three ones, yeah, that one with the handle is pretty cool. That one's free. And then the star, the throwing star one's funny. Throwing star. Plus we have extra noodle axe. There you go. It's funny. Yeah. You can do a whole collection of noodle. Weapons. Pull noodle accessories. Yeah, so pretty cool. Or you can make your own. It's just a cool inspiration. So yeah, this is designed by RWB Designs. Oh wow, yeah. Just grab it, stick it in. Tinkercad, chop off everything, but the thread and glue on top and whatever shape. Yeah, that's pretty cool. Not glue glue. Yeah. Here up north in Massachusetts, we have what we call second summer. Because like last week, it was actually nice and cool. It was in the low 70s, high 60s. And then now we're back to like 90s, 80s. It was like called second summer. It was like 69 outside. Brandy was even wearing the jacket. He was like, no, I don't know how your mom feels. Yeah, that's funny. Yeah, no, it's the second summer. So yeah, I think it matches the vibe. All right. Cool. That was a pretty good idea. Yeah, this week's time was Tuesday. Very cool, very cool design. Check it out. Good idea. Next up, we have some community makes that were brought to our attention. First up, we have a unicorn horn that was posted up by Polk. Polk posted this up. It's our unicorn horn model. And they printed it in this gold, silk gold from Azure Film in vase mode. Looks really nice. And then next up, we have another unicorn horn. This was posted by 3D Creative on printables. They trimmed the bottom to remove the holes. They didn't really need them. Printed in vase mode with three bottom layers, 0.4 and also a 0.8 line with 6 about 9 grams of filament. It looks really good. I love me a unicorn horn. Yeah, all sorts of fun uses for the unicorn horn. And then after that, we have a little wall charger for the Tesla car charging handles. I think it's more universal now. It's like N-A-C-S. So it's for any car now. Really? They're all going to standardize. That's so good. It's not called Tesla charging. NAC? N-A-C-S, something. Oh, the NAC. That's right. NAC, yes. The NAC, yeah. Yeah, I'm starting to see more people like Ford. They have adopted NAC. Everyone has. Everyone's basically going over. So they can start using the superchargers. Those other ones are freaking silly, man. So if you've actually used when it's used. They're huge, yeah. They are. Yeah, so this is a great. Yeah, so. Yeah, dual extruded, where you can just print the other little bolt, pop it in. Yeah. And yeah, there's two versions. They're ones that goes over like a shelf. So it can just clip right into the shelf, or you can add it to a wall. No? Oh, yeah, I did one for the wires, too. That's right. It's all in Fusion 360, so you can modify it. It's all parametric as well. But yeah, shout out to Webber. Yep, posted it up. Gave it a nice rating. But yeah, you can bounce it directly to your wall, if you like. We like clipping it, but you can mount it as well. Cool. After that, we have a really cool remix of the Light Saber RP2040. This user here remixed it. Daniel remixed it and made it into a flashlight. So they took the handle and added a rocker switch to the hilt, USB micro to the bottom of the pommel. And then I'm not sure what that is. Maybe some parts for the way it down or something? I think so, yeah. Yeah. Let me read the description here. It's a powerful flashlight in the shape of a light saber, using M2 screws, an LED, a rocker switch, an 18650 battery. Those are those really nice batteries. A USB, lithium ion charger, a step-up converter, it's wires, applied some thermal paste. Oh, wow. Yeah, thermal paste between the LED. Oh, it's sticky. It's an epoxy glue attached to the LED. Yeah, yeah, yeah. Caution, LED gets hot. Don't touch it. Yeah, maybe that helps to disperse some of that heat, because maybe the PLA can get. That is very powerful. Right then, if you need to. Yeah, it's very bright. Disperse heat. Yeah, yeah, those LEDs can be pretty 23-watt LED, it says here. So it's pretty gnarly. Surprised, there ain't no Star Wars branded flashlights like this. Right. Yeah, you know, it's funny. But yeah, you can make your own. So shout out to Daniel for posting this up. It's a good remix. And then the last one to round off the segment. This is not of our project, but it's just a really cool project. These are from JD Irene on printables. They call it the key tickler, Adafruit Macro Pad. So it's using the Adafruit Macro Pad and two one by four Stemma QT Neo Keys. Oh, nice. And the Adafruit Rotary QT encoders. I think this is really awesome, fully featured plug and play macro pad. Yeah, all the LEDs shine really nice. It's kind of anything you'd like. So it's good, like kind of like a console kind of for your like a stream box kind of thing. Pretty cool. Yeah. So if you want something similar, check it out. I really like the case here. It's a really nice design and the knobs, everything's printed the way it's glowing. Yeah, the way it's glowing looks sick. So it looks like it's infusion. Oh, I love the framing for mounting it. Yeah, right? Like the frame. Yeah, it's really nice design. So we're going to post about it on the Adafruit blog, but it looks like all this STLs. Oh, and the Fusion 360 file. So that's huge. Super mobile then. Did you have this pinned? I already posted. I have it pinned, like already scheduled to post it. Yeah, it's scheduled to blog. Really, really nice. So I'm double blogging it, which this one's kind of worth double blogging about. Oh, yeah, that's really cool. Yeah, so shout out to JD Irene. Oh, there's Scooby-Doo in the background. Scooby-Doo. Very cool, nice project view. And that's the segment. That's Community Makes. Awesome, we're right on time. We're right on time. See you quickly. Also, don't forget to coupon code this today. Tombstone gets you 10% off. So I'll have another coupon code later tonight. Actually, no, we won't. Yeah, no accident. We'll have one tomorrow, though, on JP's workshop. Yes. So you can check that. So that's about it. That is it. It's looking at the comments here. Yep, to dual color for the horn. It's super awesome. Yeah, thanks. I think that is it. Yeah. All right, well, just as a programming note, no Ask Engineer tonight, but we still have show and tell. So come on at 7.30 PM Eastern time on YouTube and all the channels. We'll post a link on Discord so you can join. I think we'll see DJ Devon on. I'll probably just watch this tonight. And yeah, I think Liz and or JP will be hosting while Lamar and Phil get ready for their stuff. Yes. Lady Aida had a stream yesterday with Tom's hardware. Yeah, she's talking about her experiences with the chat GPT to write some libraries for Arduino. We have JP's workshop tomorrow. That's Thursday. And then we have a deep dive with either Tim or Scott. So yeah, still got some shows throughout the week from the desk of Lady Aida. Live streams happen on Sundays. You can check those out. Do you see the Ahsoka episode? I haven't yet. I'm going to watch it later tonight. Yeah, it's a good one. I guess. A lot of weird Space Whales. Space Whales. Oh, man, those whales. All right, well, my mouth, oh, wow. All right, well, what do they have a babling teeth for? I don't know, but Ed, you're talking about. All right, well, thank you everybody so much for watching. We'll see you guys next week. Until then, remember to make a great day. All right, buddy, we'll see you tonight.
