That's pretty much it for the housekeeping. Again, we got the coupon code. We'll circle back to this one throughout the show. Prop Rocket is the discount code, and this is going to work for the rest of the day for the next 24 hours. So there you go. That is the show intro. I'm trying to keep it short this time because we got a lot to cover. Yeah, it's going to be kind of long, especially the assembly. All right, so this week's project is the LED rocket with noise generation. Should have said MP3 playback. Here it is. We've been showing it off for a couple of weeks now, and here it is complete. Make sure I got it in frame here. And OK, so we got this cool like aviator style covered switch that turns it on. And I'll eat you. It has a nice little glowy LED on there. And then of course, the rocket has a couple of new pixel rings. So we have a 12 and a 24, I'm sorry, 16 and 24 new pixel rings on the inside that are illuminated and then in a STEMA encoder. The rotary encoder has two functions that can plays with the audio. And then if you push down on it, it'll switch modes. And then you have access to the brightness control, which you can kind of see there. Everything being so right, you hit it up. You also have a fan, a little five volt fan on the bottom that has a gentle little swan of the flames on the bottom. You can kind of see it swimming back and forth. So give it a nice little animation. And it's supposed to be like a night light for kids with the white MP3 playback, the white noise generation, which is actually one of I think it's Saturn as a Voyager flew by, did some recordings of the audio there. And that's what's playing back because it is certified on. You can drag and drop any of MP3 files that you want on there. So one of the popular things is like a heartbeat or like a waterfall rain stuff like that is what you usually hear on noise generation type lamps for kids. So you can get anything you want on there. That's one of the things that PT and Lamar are trying to highlight. They want to be able to use their own audio on any of the kids toys. So this is following them those steps to be able to completely customize it to your liking on the back. We have access to USB port. And of course, we're using our lovely magnetic USB cable. So nicely plugs in just like that. And then just as easily if you want to take it out or switch out of tip. Very nice magnetic, very nice way for use of this magnetic USB. One of the other things, if you look on the inside, all modular. So cat comes right off to snap fits. You can see all the components inside here. Everything is nicely sandwiched. You can see the fan right there. It's actually keeping the boards nice and cool. So nice little advantage of that. And then the other thing they're a little like is the way that I was able to mount the oval speaker onto the prop maker itself. And then we have all the connections all routed around there on nice and neat. So you have your switch, your encoder that's just plugged in through the stem up port, the PIXL rings are plugged into the PHJST 3 pin connector right there. And that's right on the prop maker. So you just make a wire to connect that together. And the fan, the fan is kind of get through the PICO blade of connector so that easily plugs in, out and then everything is held together with a screw. So nothing is glued. You can completely edit this or change it around. The Marble saying that it's pretty subtle the way that the flames are going in there. So you can add a bigger sized fan inside the Fusion 360 file. This whole body, it's just a curve. So you can go in there and adjust your curve and they'll edit the entire body. So that is an option if you want to go with a different style of rocket. And then we're just using tissue paper for the flames here. And we're using the same type of design that are used in those fake torches that you see like at Spirit Halloween. And that's pretty much it on the inside or snap fit lid here. You can see how everything is nice and neat on the inside. Good optional battery in there that's being used as a counterweight. And then everything just the encoder and the switch just press fits in and is mounted, panel mounted on to the case. We are using the DIY USB cables because they have a nice flat ribbon. Oh, I'm not going to show it. It's a nice flat. No, that's great. The DIY USB cables. And that's how we're able to thread everything through. So this was definitely a lifesaver for that. And then we're using the socket USB connection on there. And we have several different flavors of all the different USBs from HDMI into their HDMI socket to pin to jacks to like the mini HDMI, mini HDMI socket, like USB-C, like there's so many different types. So the reason I went with this one is because the adapter that I'm using and it has the USB-C on one side and then you can plug in the magnetic tips into here. And then this just press fits on to here. And then there's like a little stop right here on the lid so that this can't get pushed all the way in. And then just a step on the side that grab on to the little triangular oh, yeah, they're good on the inside. So a ton of like little geometry all over the case, the rocket. And have this work in line that properly. Yeah, yeah, notch goes with the cable. Go. Now, like I was saying before, this USB was like a little stop so it doesn't push all the way inside. And that's what I'm talking about. Oh, yeah, the way that the wires are channeled. So this removable little lid cover here right off. You can see everything is channeled all the way through. Call it the umbilical cord. Yeah, the umbilical cord. That's what they call the rocket. They should have been labelling the guy. See how the USB, DIY USB plug, USB-C, plugs right into the feather. Now, yeah, it helps with screws. These are M2 by six millimeter long screws that holds everything together. Yeah, like they were saying before, it the way it counterbalances is so cool. Yeah, it's really nice. Yeah, usually you'll have like, you know, the kid will have a fan in there too. So a little bit of swaying that happens from that to as well as the fan that's helping the flames, a little bit of animation there. What else can we say? The different modes, I like that the StemAQT rotary encoder breakout has a built-in NeoPixel LED. So in your code, you can use that to kind of to give you an indicator of like what status you're in, which is really, really nice way because it's like all built into that breakout. And in the code, you can add more features, more modes. Yeah, of course you have to. Each kid wanted one, so I have to make two. And then for the top, it was a lot easier to just build another one. So one of the things I experimented with the slit, I talked about this last week, I wanted to have like one layer where it was, you know, printing and you could kind of see it so bright and you can barely see. Oh, right. Yeah, better, but the blue does not come in at all. Right, it gets masked with that filament. Yeah, the blue gets masked. So I went in just added the slit back in. Oh, yeah, that's definitely the way to go. It's good to experiment with it. Oh, yeah, look at that red really pops through. Oh, yeah, it's very hot over that webcam. You can't really see it. But it was a nice experiment to try to see how well the lights would push through. It's only like one layer point five. So I could cut this out, but I just wanted to leave it to show off how trying to hide LEDs could work if this was like, you know, a brighter filament color. Mm hmm. Yeah, I think in the code, you can you can probably make it brighter. I'm not sure. But you do have that control when you are when you're when you're doing the code. Yeah, yeah, I think you could go into the library and maybe change it. But yeah, you could definitely do some more stuff to it. It's good. Yeah, that's a good point. OK. Yeah, I really haven't used the rotary encoder. Stem acuity breakout. But yeah, so step back a little bit. The the feather RP 2040 has that built in stem acuity connector. So it makes connecting any any sort of I squared C sensor. In this case, the rotary encoder like just plug and play, which is really nice. And then with the prop maker feather wing, we're huge fans of the prop maker feather wing. We kind of are the reason why there's a prop maker feather wing. It's it's got. It's got all the things you need to make like an advanced prop. The what's kind of cool is I didn't know that you could use the RGB pins to power a five volt fan in this case, which is really nice. Normally it's it was designed for three watt LEDs, those really bright RGB LEDs. But hey, you're using it for Lamar came up with the idea like, hey, let's use those pins so that we don't need like an extra five volt boost to to get the fan to work. So that prop maker feather wing combined with the RP 2040 feather, like it's like the perfect combo. Um, the it also has a built in accelerometer, which I forget about. So like you wanted to use the accelerometer. Let's say you wanted to do like a like a prop from a video game, like this whole build is completely adaptable. So if somebody who wanted to design their specific like kind of handheld prop, like it already has USB battery charging built in to the feather. So you literally just use the battery and now you got yourself like a prop that you can hold and take it around with you. You can power a fan. You can have the three watt LEDs. You can have the accelerometer. You have a fan. Um, you could probably do like that, uh, that like vape smoke. Like you could do so much stuff with just the prop maker and the feather RP 2040. Yeah, don't forget the sound effects. MP3 playback is kind of difficult to do in Arduino. But with circuit Python, you can literally drag and drop it. You can have the audio play different sounds depending on kind of like the think about like the luchio blaster that, um, that JP John Park did, like that could all have been done with the combo of these two. And then you got the knob, like the rotor encoder. Yeah, I'm going off the rails here with when I highlight what DJ Devon is saying about advertising the MP3 playback because most microcontrollers can only do wave as the usual default is. So yeah, we should have put that on their MP3 playback. Like, yep, yep. Yeah, the prop maker does have Fible out. It's got three of those pins. The RGB, the RGB pins are all five volt powered. Yeah. Yep, yep, yep. Definitely good, good, good comments there. Um, yeah, there's a lot to the prop. Yeah, that's a good point from Andy Callaway too, saying that the airflow I should have put, like little holes on the top so that there's actual air flow coming through. So yeah, that is a pretty good point. Yeah, yeah, that's a good point. I will try that. Yeah. Yeah, it's adaptable. I mean, you can just print out the top of the rocket or the part where the fins are. I mean, I might be getting air from jump over to. Oh yeah, let me jump to the camera. Yeah, you can see that there's still some holes there. But I'm sure there'll be way more air flow if I had some ports and poles on the top. I will definitely try that. Yeah. Yeah, the other project we have, I actually have it up here. Is this medieval torch? Yeah, yeah, I'll leave it alone, but it uses just a bigger fan. Like, it really comes down to the, excuse me, the size of the fan and each fan actually has like an airflow rating so you can get like one that's specked out to be like pumping out more air. I found that out when I created a little mini fume, solder fume extractor. Like I went down the rabbit hole, like searching for fans on the on DigiKey's website and we have one that we use for that for that project. But other than that, you know, it's it's working pretty good. It's subtle, like you said, you see the flame moving slightly. Oh, yeah, this one. Yeah, and I would have to code it to the motion sensing. So when the kid is playing with it, you know, that jostling around that happens when you just touch it because of the way that the local court is. That would have been cool to add some like different sound effects or something. Yeah, that would have been cool. Something. Yeah. You can add a button so that when you push the button, they can do a countdown and like maybe the third function. Yeah, cool. Yeah, a third function. Yeah, so that's all up for the folks that are into writing code and maybe they want to modify it. They can add those features. So for starters, it's got a lot. Oh, here's a good comment on from PJ Devon. When shopping for fans, always pay attention to the CFM. That's called cubic feet cubic feet per minute. And that also means it's a louder fan. There's a bounce between noise and CFM. And Teth is saying you're making me want to stick a 12 volt fan blower like the three to three style. Oh, yeah. Yeah, that would be crazy. Yeah. Yeah, we have airflow. Yeah, Lamar suggests the fan because of how small it is, the picoblade connector. And because we have it in the shop, you wanted to test out how that looked. I did like how small and compact it did make the circuit. Oh, yeah, that's true. Yeah, how small do you want it? Yeah, here's another one from Roz and lights that countdown to bedtime or show that it's not time to get up yet in the morning or popular ideas, too. Yeah, those are all great ideas. All that connected to a different I.O. So you can set up all that stuff on your own, like have a different schedule. Yeah, we do have feathers and weekends. Awesome. Yeah, we could swap out the feather I've been 2040 for the ESP S2, the ESP 32 S2, for example, could probably work. You got to be careful, though, if the pins are going to line up. I think there's a there's a specific pins that that the prop maker feather wing need. So just check the data sheets. It's all documented there. And then you can decide whether or not you want to do Wi-Fi or if you need to add a like an airlift feather wing, for example. Yeah, all really good ideas. All right, cool. I guess jumping to the guide. Take a look at the switch over the assembly stuff. Do you want to drive it or do or do is it good if I drive it? Oh, you can drive it. OK, just tell me where to click and where to scroll. All right, so starting off assembly or the overview page just sort of giving you the pitch of what this project is meant to be used as. Of course, the nightlight noise, white noise, generation, front maker, other RP 2040, which, again, I did not know that these two works together. That's beautiful. Unfortunately, it looks like the RP 2040s are out of stock for the feathers. I believe those will be back soon or you might have one. Yeah, yeah, yeah. Highlighting the product is because of the way the pink ones are. Yeah, those special limited edition pink. Yeah, the parts. This is just like a fraction of the parts that you'll need. Some of the other ancillary stuff for all of the ribbon cables, the connectors, the screws. This is definitely a build. Oh, yeah, I should have. I'm trying to like scroll into the thinking it's my I know. Yeah, if you want, go ahead and take it over. That way, you're way more in control because I'm having to like kind of just keep going. This is going to have to look exciting. All that you scroll down and see a lot of the parts here. And then if you keep scrolling, there's so many screws and wires and all that good stuff. But oh, yeah, screws. Don't forget the screws, y'all. Yeah, we've got a nice mini oval speaker and the the prop maker feather wing has a pretty decent amplifier on it. I think it's the Pan 8302 if I'm not mistaken, which will give you a pretty decent. Audio out. Yeah. OK, and two screws, the metal machine screws. You'll definitely need a couple of those just because of the way the how small the the component sandwich is to have everything together. The Molex Pico connectors. There's a box. Stk cables. Yeah, DIY USB cables. Those are great for like all sorts of embedded projects. Yeah, there's quite a bit of the stuff that you're going to have to DIY in terms of making the the spade connectors for the the aviator on and off switch. Yeah, you need to assemble that yourself. It just comes with spade connectors. You have to get your own wires and solder all that up. Right, right. Cool. Yeah, definitely a more advanced project, not intermediate just because of how small the scale of all this stuff is where you have to route all the cables and keep everything nice and tidy. Yeah, for sure. Definitely rings. You need some finesse to solder to the pins and all that. Oh, the way you even assemble the ring holder. Yeah, it's quite a. Because they're days of change, correct? The 16 and 24. Yeah. All right. Well, let's get to that. Next page is the circuit diagram. You'll definitely click on this to make it a little bit bigger. Yeah, it looks clean here because it's not showing any of the extension cables that you're going to need. So for the speaker, it's not the speaker, the fan, the switch, the new pixel rings, the way that's all connected. You actually have to mount this and solder it in place. So that's one of the things that makes it challenging because you have to mount it onto the part and then route all your cables to measure them all up. But if you need the not the fusion, the fritzing file that is available on here as well. Oh, nice. Yep. Next up. Liz did a good job of doing the installation and code page for this. And you can shout out to Liz. Yeah, I can run through it real quick. Yeah, the really important thing that she added on there was the ability for the fan to actually work with the. Free watch LED. So that was that is definitely needed in code. Yep, there's an enable pin to turn on any of the high power stuff for the prop maker feathering, mainly because like when Lamar was designing it, she wanted it to not like eat up power right away. Like you want to be able to kind of do like a deep sleep thing that was really important for the lightsaber projects. So that's why the hardware is designed to kind of need to be turned on in the code, these these these power pins for doing just neopixels and RGB LEDs. Like you want to turn that on in the code, but that's here. Enable the speaker output and the fan pins is all here as well. So you just want to turn those on. We're using the the seesaw library so that we can control the neopixel that's on board the rotary the rotary encoder, STEM, a QT breakout. We're using the MP3 library from Jeff Epler, who's on the team and the the LED animation library as well. We're using pulse here, but you can add in as many effects as you want. Rainbows, chases, there's a couple other ones like comment. So you can do some really cool, simple animation. You can string them together as well. But going back to the code here, we are just kind of setting up all of the pins for all of the different components. Speaker, fan, the LEDs here. We've got the MP3 audio right here is where you want to make sure that if you're adding your own MP3 audio file, just make sure you change the file name. You could also do some stuff where you're like picking an MP3 folder and then like you can cycle through them. There's that's another option, too. Here's where you want to change the number of neopixels. So if you're scaling this up or scaling it down, you want to adjust the number of pixels. Here's the brightness for the pixels by default. It's point three. You can actually increase that if you want to have it more. And then you can change some of the colors here for the the neopixel that's on board the the rotary encoder. So all this is nicely commented out. You can take a look at the loop here. Just kind of find out how we're looking for. We're checking for the mode if it's in a certain mode using the rotary encoder and you can pretty much walk through it here. Yeah, there's there's special modes for the various neopixels because you are working with the neopixel rings and the neopixel from the Stemina QT rotary encoder. But yeah, check it out. Here's what your file system looks like for your circuit Python drive. You want to have all the libraries. When you download this button here, the download project bundle it saves you a lot of time because it'll grab all of the libraries and the MP3 file. Yeah, it'll just kind of grab it all. But this is a nice kind of check to make sure that your file system is all set up nicely. Here's a little bit about the MP3 file itself. It is an actual recording from NASA Saturn radio emissions, which is pretty pretty damn cool. And then here's a breakdown of how the code is working. So how the mixer is being used for the audio, how the neopixels are running, how the rotary encoder is running and the loop when you got those two control modes, how to turn up the volume using the rotary encoder, how to turn up the brightness using the rotary encoder. Super excellent breakdown. So definitely check that out if you are a beginner. This will definitely help you out to understand exactly what the loop is doing. Alrighty, next up, 3D printing, Pedro. All right, you are going to need a little bit of support material for the rocket bottom portion, just because of the way the tabs are set up. And what's really causing that is just the way the fins are because they're sort of protruding out so you can't print it on the other side. Otherwise, you would need any supports. You'll need to have a print. Are those supports manually added with the... No, those are automatically added. And then when you put your mouse over there, just using that support blockers. Oh, yeah, that's what it is. The bottom, which will be the top of the fin because you don't need any supports there. They're all a 45 degree angle. And then the USB port opening shouldn't need any supports on that because of the way the bridge isn't that long. So your printer should be able to print that. If you have had a cooling. Yeah, and you only use like a white translucent PLA to get the glowing effect. I have some of the support settings all listed there so you can update that. And yeah, pretty easy, not too hard, just a lot of pieces. Yeah, for sure. But that's the main one that you want to shout out because everything else is kind of print as is, but you do want to do some special support blockers on those various fins and features. Everything is oriented the way that I printed them. So that should be good. I think the only other thing that might need supports is the speaker mount holder, just because of the way that it rises the speaker away from the prop maker. I saw some DJ, you know, somebody posted a DJ Devon, the speaker. It's kind of dangerous having it accidentally plug in the battery where the speaker goes. The speaker is a different connection. Yeah, the it looks like it's the same in the circuit diagram. Yeah, but it's not. It's just the way the first thing is laid out that it's double. Yeah, it's not going to. Yeah, you're not going to get that one wrong. Yeah, it won't fit in there. Yeah, and once we get to the assembly page, you'll see it. Yeah, and the same thing with the the JST connection that I'm using for the switch. It is a female or it's a socket. You can't plug that into because they're both sockets at it. Yeah, yeah, yeah. No, that's clever. That's a good way to when you're assembling it, you can't do it the wrong way. Very good. Good things to think about. All right, let's get on over to the hard, the hard stuff. All right, cool. So I think of soldering your headers. You can actually get this preassembled, but I just wanted to use the short headers for this. So we're using the sockets on the top of the feather, the 2040 feather, they solder in upwards, pointing up. And the prop maker will have the the pin headers pointing downwards. They'll lock into each other. I'm using a breadboard here to stabilize and solder this on correctly. So it's nice and even or straight down. Yeah. Oh, yeah, you can see that it's Pico. Yeah, it's tiny. Yeah, it's funny because like the I guess the the the pin spacing is the same. But the foot, yeah, the solder screen. Yeah, the the silk screen, rather has the same outline for the the JSTPH connector, but the Molex connector is a little bit different and it's definitely smaller. But yeah, that's it says right there, speaker. And it's a four eight ohm speaker that that you should be using there. Yeah, that's pretty funny. You also got a built in potentiometer to increase the amplifier here because it does have a built in amp. And that's that little pot there. This is ball for volume. But yeah, it's a really nice board, the prop maker feather wing. If you haven't used it yet, you just look at it. Yeah, it's kind of freaking accelerometer. Like, oh, yeah, it's really, really nice. I highlight in the guide, too, that the way you want to solder things is from the back. If you go back to that image, the you could see the RGB pin, pin, the ten help sockets, whatever pins there. Yes, look at how close it is to all of those little diode. Yeah, that's three. Yeah, yeah, above that, above that, right here. Super careful, solder to the back side of that because I ruined two boards soldering from that. Yeah, so you want to be super careful. And what I'm doing is see the two strain relief holes right there. Oh, yeah, these are strain relief holes right here. Typically, yeah, so you can pop the wires through there, bend them over and onto the to the holes and then on the back side, solder it from the back side. Yeah, yeah. And because these are ground pins, like common ground pins, they take a little bit of extra heat and a little bit of extra time. That's just the way the ground planes are. Like it's always a little challenge to solder to those. They're not as simple to solder like the digital, like the regular GPIO pins. I found it always difficult to solder to these these pins. Yeah, I ruined two boards. I know it's it's what you learned. It's definitely you learned and hey, now you documented it. Correct. Well, we're on the subject of the pins. DJ Devon saying he cuts longer pin headers. So, yes, I ran out. So I had to use the Raspberry Pi Pico short headers, which are longer. So I was able to cut those to cut that down to size to fit on the feathers. So if we are out of those, the Pico Raspberry Pi Pico between 40 short headers for those will work on this. So you just got to cut them down. I got it in there, but that's where you're watching the shows. You get all these other nuggets and forgot to put in the kite. Got it. OK, so this is just showing, you know, a real world of what the actual connections look like instead of the fritzing. You can see here the fan plugging in that through the Pico connector, the speaker. And you can see there, there's the Pico connector for that one, Pico blade. And then the the switch has a regular two pin and just JST, the H. Yeah, and this is the enable pin that will actually turn the the power regulator off so that way you can actually still recharge a battery when the circuit is turned off. That is super important that this that this prop maker feathering can do that because a lot of time if you're using like a the what's it the lipo backpack thing, like you'll be charging the battery, but the circuit will still be on. So it's really nice to have an enable off. It'll turn off charging too. So it's like, oh, man, I got to leave this thing on exactly. So you have like a sound effect, you know, that's annoying while you're charging your battery. But no, the prop maker and the the feather Rp 2040 use a legit enable pin that's like through the microcontroller. All right, here you can see kind of how you did the RGB pins. OK, we're on. This is how the speaker is mounted. The oval speaker can mount anyway. It's like universal as you mount it on the left or the right side, the backside pointing up, pointing down, whichever gives you the best audio. And then on the side there, there is a this visual leftover of when I was using the mini boost on the side. And that's where that would screw into. So if you want to use the mini boost, it will definitely cut down on the whining that you might be able to be hearing right now in the background. There's like sort of a like a high pitch squealing. That's because of the prop maker. It was powering a fan, all the LEDs, the switch LED. So it does give it a little bit of stress relief on the power. Yeah, I think if you want to use the feather M4, it has like a much higher quality DAC and that'll reduce any noise that's introduced because I think it's doing PWM audio for the for the RP2040 because it doesn't have a DAC. So that's just some things to look out for. Yeah, so that mounts on there and the screws go in through the top or through the backside. You see how that it's mounted there. And then the wires, you just want to coil them up all nice and neat so that when you're plugging the socket and the the pins together, none of the wires get in the way. OK, let's go down to the fan. Don't put it together yet, though, because you first need to assemble the fan amount. So it's one of the things that it's like, oh, cool. How is this going to work? Oh, you just mount the fan to everything else. So the fan includes these long screws that were like the perfect size with the nut and all to hold it to. This is what I'm going to plug into the new pixel ring. And then on top of the fan is where the feather gets mounted onto. So those just require the included screws for the feather around. Sorry for the fan. That's what that'll simply look like after you're done, the feather mount. And then after that is attached to the feather and the fan, then you can attach the prop maker on to the feather. That looks like next up, you will set up your LED rings. Start with the 24 to measure how long you want to drive it this into your LED ring mount just to see how long the cables you're going to need. And they're going to route from the back of both of the new pixel rings. So solder from the back is again, same deal here. If you can look at the front of the new pixel ring, there's all the resistors, everything is all right there. But on the back, you have a nice clean area to solder from. That's what that looks like there. And you'll do the same thing with the 16 new pixel ring. We connect all those together and then attach a three pin JST connector. And that's what's like to the prop maker. Right, because it has a built in. It built in a connection for new pixels. So some of the new pixel strips do have that three pin connector. So we'd be able to easily without soldering here. It's just because of, you know, custom sizes. Yeah, with that that thumbnail, you rolled over there. Once that is connected, you want to make sure that everything's plugged in. You know, I'm just showing you, you know, here's the battery. Here's the on and off switch with the JST for the LEDs go. And then the fan picoblade connector to where all of that gets connected, make sure all that's connected before putting it into the bottom rocket body, because you're going to need to thread all the wires through that USB port opening. So you'll thread the wires through first and then from the bottom, you will push that whole ring sandwich attachment through. You want to like bend on one side so that tabs will move out of place. And then you can sort of push in at an angle and it'll pop right through. And you'll rotate the tabs so they all align. And then we're just going to use the M2 by six millimeter long screws to attach that together. Oh, OK. Moving on, we're going to build our DIY USB cables. I'm using the 30 millimeter long, I'm sorry, 30 centimeter, not millimeter, 30, which is 300, you know, but they're sold as a centimeter. Sorry, I need to update that 30 centimeter long DIY USB ribbon cable. And we're using the USB A socket to the USB C plug. And the first picture I'm showing which way the little contacts plug into. Yeah, that's Andy pointing to see visually. Yeah, because I kept plugging it in the opposite way. I was like, oh, man, these things don't work, but it's because I just plugged them in upside down. Yeah. And because it's USB C, it doesn't matter which way when you're actually plugging into the board, it doesn't matter which way. Oh, yeah, it's reversible. Double-sided, it's reversible, yeah. All right, there. And then we're going to attach the umbilical port, which I'm just calling the pipe here, flat pipe. So those, you just align the tabs to the little. To the corresponding malls, yeah. Yeah, it's just three of them. And just screw the other another set of M2 by six millimeter long screws those screw in together and then thread. Once all that those wires are inserted into the pipe, you'll thread those into the case, all the big JCPorts, all that should fit through there. And then you just attach that to the main case. It should have a nice attached rocket by then. So we can move on to assembling the rotary encoder. The Stemma rotary encoder board is just the board. So you're going to have to get the rotary encoder separately. It is listed in the product page for that. So you get the rotary encoder plus extras. I think what the product name is called that will come with the you know, the nuts and the encoder itself and then the little cap. Yeah, I should know like a nice like metal neural knob for this. Dang it. Of course, yeah. But yeah, that was a piece of cost. Yeah, people can do that. They can machine their own do if they're really fancy. So the so otherwise it's easy to. Yeah, so identify where the new pixel is on the rotary encoder and align that to the slit on the case so that you can see it diffuse once that's hooked up. You connect your Stemma QT cable to the ready PCB board and then attack just panel mounted with the included washers and the nuts. That's what that looks like. There, power switch, a little bit of again, DIY this so you'll solder the spade connectors onto a JST socket connection. Just make it nice and short because you don't need to be that long. You already have an extension cable that's going to plug into that. And we have the power being shared between the I think it's like the headlamp is what they do. Yeah, the LED. Oh, really? On the credit page for this, it shows you if you want to have the LED on while it's off or if you want to reverse, there's multiple ways to connect this based on when you want the the light to turn on or off. And one of the ways is through code. I think the very way that I hook this up is because I didn't know how to code it. So you can physically hook it up this way to work how you want. Yeah, that's true. It has a built-in resistor of a swimming. Yeah, yeah. OK, that's handy. One less thing to wire. Jeez, so much wire. Coil up all of your extension cables so they're not a mess everywhere. Should have enough to boil it up. Now you have plenty of room for any additional things like the battery that I'm going to insert in here. Moving on. Yeah, panel mounted panel mount comes with the nuts and this washers. The washers. And this is where I'm showing the USB adapter, how it just press fits into that little opening there. The battery gets inserted onto the opposite side of where the USB connection goes. I'll install the magnetic USB-C tip into the adapter. So if you want to have that ability. And then the lid just match the little cutouts to where the USB port cutout is. And it should be just press fit that. Bust out your scissors and some construction paper. Yeah, you can print out this page to have a little outline or you can just freehand it. That's what I did with these. And the good tabs using double. Have the kid to do it. Have your kid claims again. This is intricate, man. Like you and I know that looks pretty intricate. You got to have like dexterity to do all those curves and all that. Yeah, just have the tech out the larger portions and then go in and cut out the little grooves that are making up the fires. I wonder if streamers would have a more effect. Maybe, maybe. But at that point, I am out of time. I can't test any. Oh, yeah. We had to go back and do stuff. Yep. Yep. Last minute. And I was like, no, like, you know, let's use the RGB pen. And it's like, oh, OK. Right, right. You have to go back and redo other stuff. That's it for the cap. Just press fits right on. It is tapered. So it's popping in. And that's pretty much it. Pop the cap on and let you ready for blasts off. All right, cool. It's an intense build with patience. And it's a good weekend project if you put the time in. But yeah, all the parts. Yeah, with all the parts, it might take two days to print out. Yeah, for sure. The assemble and all that. But it is future parts that we can probably use in another prop that's going to require a P3 playback with LEDs and a 3 watt. I don't know what else we can use the fan for. The accelerometer. Accelerometer, definitely. I really wish we had a lot of adding something for that. I mean, since it wiggles, it would have been good. Turn it upside down. It does something else. Oh, hey, look. It does work upside down. The flames anyway. Yeah, yeah. Is it because of the way it's hanging down? Gravity that's messing with it? I mean, it's a nice little subtle little fluttering. Let me see if I can have my torch here. Find it. Yeah, there you go. I'll use the fabric. We both have our fake flames. Yeah, this is that fabric mesh. It's like silk. Yeah. Yeah, it's like a silk. Yeah. Kind of stays up. We have a rocket too. Super fun. All right. Let's see if any comments. If you want to pick up the prop maker feather wing or any of the other parts and components, you can use the coupon code PROPROCKET and get 10% off your order. And we got a couple of comments here on the Discord. Some good banter about, I think DJ has been saying, the audio, how they translated the radio waves for the audio, for the Saturn flyby. It's interesting. Oh, interesting. Nuggets there, how they translated the audio there. Oh, and there's some suggestions here to use a ferrite core to help with noise suppression. I had not thought of that. That's a good idea. And streamers are a good idea as well. I think it's a good idea. Yeah, yeah. It's one of those where I had like no time to actually go down to the mic holes or whatever. Yeah, good thing streamers. Actually brandy paper like at Publix. Oh, that's funny. They're on grocery shopping. Yeah, that's a grocery shop. Cool. Yeah, check it out. There's a prop maker link. Very nice. And we have 3D models too of all the components of the prop maker, the feathers, the neopixel rings, even the speaker, I believe. All good stuff. And of course, all those parts too if you want to use it on a different project, like you were saying, you can't open the Fusion 360 project and actually rip them right out of there as well. Yeah. What I usually do is grab the outlines, the sketches, and import that into my design file. Or not even I just ping it in. Yeah, you have a link here to the playlist for Fusion 360 layer by layer. I think I have one on how I did the mounting brackets for the prop maker feather wing for that lightsaber and the darksaber too. So folks can take a look at that if you want a different approach to how to design these. Oh, how to mount that vertically, yes. Yeah, you actually have a holder that slides into the cylinder. So we'll be using that because a Mandalorian's coming out what, March 1st? What is the other stuff that we got? Tron, the Tron light cycle run coming out. So we got to do some props for that. I'm sure I'm going to have to revisit these parts, components, and the 3D files to mount everything together probably in the next week or whenever. Yeah, yep. All right, well, that's the project. Definitely check it out. We have about 10 minutes left. So we're going to speed around the next two segments. Right in two, community makes. Oh, I want to do. Oh, Shop Talk, yes. Do that. Yeah, let's do Shop Talk real quick. Yes, this is the way. Oh, I can't wait. I'm so jealous that Disneyland gets Mandalorian actor dude with Grogu, and we don't. All right, so this is a preview. It's actually prototyping, I guess. And then we'll do Shop Talk. Oh, this thing is so cool. Yes. Yeah, so Liz Clark had a fun idea to use the new Feather ESP32 S2 with the reverse TFT. Display to create a controller and a monitor for Octoprint. Octoprint is a way to control your 3D printer through a kind of web interface. And she's using Adafruit I.O. and the MQTT plug-in to talk to Octoprint and display some status. So here it's connected to my printer. And it says the print is finished. So I can confirm. I can use the onboard buttons to confirm. It's using the onboard Neopixel to do a little bit of an animation, just blinking green. Let me know that it's done. And then we're using the progress bar here that's all done in circuit Python. And then we have some buttons here so we can control. So here I can confirm. It tells me that the status is operational. You can do bitmaps. So here's the little Octoprint octopus. And then I can do cool down, heat up, or reboot, which is really nice. And you can adjust that and change it as you like. But yeah, I got a little 3D printed stand for the feather, ESP32 with the reverse TFT. And yeah, just kind of a first look at using the new feather and a glimpse at Liz's project for this week, which she'll have a guide hopefully coming out later today. And yeah, we'll probably do a video about it and she'll do her own video too about it. But it's really, really nice and handy to have this standalone device that gives you status updates and you can control and cancel prints too when it's printing. So it's a really good way to kind of receive data from MQTT with Octoprint and how to push data as well, like commands to your printer. Very, very cool. And then of course the Neopixel for things. You could also expand it to add sound effects. I really miss my MakerBot back in 2012 where I'd get like this really nice chime and they still can't get it. Yeah, I don't even remember what it sounds like. But you can just- I don't remember there was piezo buzzers like installed in some of the printers and they never made any audio. It's like, why do you have this buzzer in here for then? I don't know, but now in CirclePython you can definitely do that. And this could be scaled up to a PyPortal or a MAG tag display, eating display. This is just like a really small version of it using the new ESP32 feather with the reverse TFT. It's got USB-C and a couple buttons. So it makes it really handy for I think a really small display controller. So- I'm to have control of my Octoprint rig with this. Yeah, cause like sure you can control it with your computer and your browser, but let's say you're editing a video, you're rendering if you don't want to be... Yeah, you kind of run out of room. So it's really nice to have something off-screen, off your desktop, that's a standalone device that's dedicated for that one thing. And you can use the NeoPixel, you can have a NeoPixel strip that can be scaled up or any number of different things. So really, really good. You just haven't seen anybody do this before. And because it's 804.io, I can be on a different computer or a different Wi-Fi network. And as long as I have my credentials all set up, I can be looking at my printer from a go, from afar. So that's that one, that's that bit. I know the next thing we really like are- Super handy. Yeah, we really like these magnetic USB tips. So here is a little holder for these magnetic tips. The cables come with three tips, Lightning iOS, Micro B and USB-C. And this cable here is the magnetic cable. So here I can now switch this out for Micro B and snap that in there, plug it in or leave this connected to my device. It's reversible so I can make it go this way and it still works. When you plug it in, it has this green LED. It's really nice, it's woven. So this is very flexible and it's a nylon woven, super awesome cable. So I'm gonna take this off and plug it right into my feather here and now I have, it'll start booting up here. There's the IP address and then, well, it doesn't show it yet because it's connecting. There's the IP address and it's connecting, doing some stuff and it'll pull in that data. NeoPixel is telling me it's connecting. And then there, there's the status. My print is finished. I actually do have a print printing. It's the status before the show, it looks so cool. Yeah, I'll save that for next year, but definitely if you wanna pick up this holder, you can design your own or 3D print the one I have. It's on the printables. I have a link in the show notes here. It's a really simple kind of holder. Oh, where is it here? Here it is, it's on printable and let me share my screen, almost there. And there it is. Yeah, so check that out if you want. And here's the cable. It comes in two flavors, a meter long and two meter long. Yeah, and then here's the design infusion. You can change the dimensions if you wanna add more or add less. I got two of the cables, that's why I have double my tips. And they just, they're all magnetic so they kind of bundle together, which is okay, but I thought I was gonna lose them. So that's why I was like, ah, let me just make a quick little holder. They press fit in as well so they don't fall out. They don't fall out here, they just stay intact. Yeah, so they press fit. So that's a little bit of a prototyping and shop talk. All in one, moving on. Community makes, I don't have the video loaded. So we either skip it or you just show it to us. I can just show it, yeah. So Erin made us a LED nude project with, where am I? Do I have to share my screen? It is, it's the heart of the feed. Yeah, it's from the movie Moana. Cool with all the bright lights. Oh yeah, that's how it is. That's pretty cool, yeah. So she was showing how to do a RISM print to this. All we wanted to try it out with just regular PLA. So I'm printing this at 100 microns and it's okay, it's pretty good. So there's an LED nude on the inside here connected to a 2032, dang it, I forgot the number of the coin cell battery. No, you're right, 2332. It has a built-in switch, so you can turn it off. Coin cell, very popular coin cell. Yeah, so the back that you made for this just press fits right on. And of course, the kids love this. We have had Moana playing on loop in the background for the past three weeks or something. It's like, how does she know? If the attraction over at Epcot, if that was open, the Moana water walkthrough thing, that's open, we wouldn't have shot video in there, but. Oh yeah. We're gonna be able to shoot a video wearing this with Moana herself. That's a great design. She's walking through his hair, right? Yeah, yeah. We all have a hey-hey puppet or something. But yeah, this is super cool. And now all the songs are just coming out. All right, I actually have her learn guide. It's in moderate, oh no, it's been published. Yay, so check it out. She downloaded a model from Thingiverse and brought it into Tinkercad and did the front half. She added the necklace loop and you can download her STL remix. We also have the cover that we designed in Fusion. And what she did is a little bit different. She printed it in a resin printer. I forget which one. I think it's like the L glue printer, but it looks fantastic. It looks really nice. $100 one. Yeah, you definitely gotta be careful with resin prints. They can get brittle over time. You gotta do a little bit more process processing, like curating and washing it and cleaning it. Yeah, she actually talks about it. But she goes through all that in her video. Yeah, so you can see all that. But the electronics are pretty simple. It's just an LED noodle and that coin cell here wired directly into the pins. I think she hot glues it in place, but you could try to press fit it in if you wanna redesign it. And just a shout out to the original. Well, it's actually a remix of a remix on Thingiverse. Here's the original she added. She needed to carve it out and added the loop, the necklace loop. Here's the original from Thingiverse user M.Kratz. Yeah, there's some glow in the dark paint here. It's in two halves. Here's that glow in the dark paint that you could use Aurora or you could use an LED noodle and have it actually laid up, right? So it's up to you how you wanna do it if you're really into the proper not. But yeah, it just got published, I think. So check it out if you wanna check out that guide, but you did the time lapse and in PLA, it works out really well if you do 100 microns. So there you go. Here's on the overhead. Here's what the inside of that guy looks like, even though we're already looking at it there. Here it is. So nice little simple nude circuit. That's pretty much it. It's power ground. You can hook up external slide switch and do a little cut out on the back of the clip. Okay. So you can definitely add a slide switch to that. And then the only other thing missing is probably like some screw mounts, since there are screw mounts on the coin cell holder. Yeah, that's true. Some additional things you can add on there. Other than that, yeah. Super cool way to have a little nude. Yeah, those are, those noodles are, you're using, yeah, it does, it does. You're using the shorter noodle too, the 130 millimeter noodle? Not the shortest one? Yeah. Yeah, that's the only one we had left. I wasn't gonna use green. Do we have green? No, I like it, because you don't have to like, really like coil it, it can just kind of look good there. And because it's green filament, like it lights up pretty nice. Yeah, the color palette is nice. Yeah, Aaron's using the actual green one. You have to like bundle it up. I think we'd like use, wait, what? You have to bundle it up. Oh, to extend it? No, just to fit it in, I think. You can see here. Okay, she had to coil it up. The short noodle actually is okay. I thought she used the shorter one. Yeah, cause this is like the perfect size for it. Yeah, yeah. And even though it's yellow, because the PLA filament is green translucent, it actually works out pretty well. It doesn't have to be green. Yeah, yeah. Yeah, that fits. Yeah, no, it's great. And then of course, yeah, again, I'm printing it vertical. That's why you have the higher quality. So instead of printing it flat, you would get such a low resolution. Like just be able to see all of the print marks. Actually the cap is printed flat. Oh yeah, the cap really shows it, yeah. This just printed upwards. And again, it's surprising because this tiny little tip is what is touching on the print bed. Everything else is like brim and then supports. Right. And that's like 50, the angle of the degree for the supports, like 50 degrees. So it has supports all over in the back and all over in the front to hold it in place. Yeah, cool. There, it's the PLA version of that. Yep, also I got a 3D model of this coin cell. So if you wanna use that in your project and like get the measuring of the mounting holes, if you don't need your calipers, go ahead and download my 3D model. It's in our CAD parts repo on GitHub. And if you wanna pick up the coin cell and coin cell batteries, they're in stock and you can get 10% up with our coupon code prop rockets. Also pick up those noodles too, the LED noodles. Are they back? Yeah, the noodles, the green ones were. Just type in nudes and you'll find out what's in stock here. We got the warm white, which is great as long as you can change the color when you have a diffuser like the 3D print. You got blue, those are in stock. Yeah, I think all of them are in stock. Pink, if you wanna do pink one. These are really fantastic LED light sources for your props. So get them all. Yeah, I'm thinking like, do I use this for, like do we redo the Tron hoodie project? I know, right? Yeah. It's not long enough. Maybe if I just do little identity discs like on the shoulders, like. Yeah, yeah, it's tough with these noodles because they're pretty high density and you could daisy chain them together but you need more volts and. Yeah, that's what we're. They get tricky to power once you get. Having longer ones. Yeah. Yeah, factory is letting us know what is and what is not possible with length sizes of custom sizes. But this is the size you used. Yeah, this is the one you used here. Yeah, yeah. You get pretty bright. I love the silicone feel on it. Yeah, just use the resistor. Mm-hmm, the grippy. So before, it's got some grip and it's definitely like some silicone or something. All right. All right, so cool. Okay, well, we are pretty much out of time. We have a ton of community makes. We're going to get to those next week, though, because next week is just this project, which will be pretty simple. There won't be any advanced LED wiring speakers. But all that craziness. Super. Yeah, super handy. Super useful. Super handy. Yeah, super handy. But yeah, we'll save all the community makes. We got a ton of them. It's really, really great to see everybody putting the effort into sharing that they've made a project for made of fruit. Like that's that makes our day. So we appreciate everybody posting those, but we will share those next week. Don't forget, coupon code is proprocket. If you want to pick up anything in the Adafruit shop, support this show, support everybody at Adafruit, Lady Aida herself, Baby Aida, Mr. Lady Aida. We have a show tonight. Ask an engineer and show and tell is going to be on tonight. I'll be hosting Joe and tell. Pedro, you'll be on too. That's at 7.30 p.m. Eastern time. Come on in the Discord chat room. We'll throw in the invite link so you can join our stream yard and share your projects. We hope to see your projects and you tonight. And then after that, at 8 p.m. Eastern time is Ask an Engineer, a full hour of Lamar and Phil talking about new products, open source hardware news, sneak peeks, ion MPIs and much, much more. That's gonna do it. Thanks everybody in the Discord for hanging out with us. We wish everybody good luck. That's a really good comment and commentary I can't get to because I gotta go eat. Yeah, I gotta use the bathroom. Thanks everybody. Yeah. Oh, I hope, Devin, I hope you come on and show and tell. I'd love to see your progress on that case for your steps which that thing's so bad. Cool. All right, everybody. We will see you later tonight. And next week, I'm gonna tell them. Don't forget to make a great day. Make a great day. Bye everybody. Good night.
