 Hey lady, what is this? Hey everybody and welcome to show and tell it to me Lady Aida with me Mr. Lady Aida and this is long swimming electronics show and tell on the interwebs and the known universe People from around the world come on by show us what you're working on We're here for another 20 minutes or so and then we go on to ask engineer So bring your 3d printing your soldering your coding your synthesizers your cats your LED cats your LED synthesizer cats Anything similar like that and more retro hardware you name it come along and show it Let's first start off with Pedro Pedro. What are you cooking up this week? It's up super hyped that new Tron rides about to open up. We got the email that will get our reservations tomorrow So I'm not gonna sleep or so I think we don't have a ton of people so the new Tron right did they base it off the original? Did they blend it with the latest ones? What what trons? What trons is it? Yeah, so there's one in Shanghai, and it's just a clone of that the only difference Okay, and like right next to space mountain and tomorrow land. So yeah What Tron era did they do the 80s Tron or do they do them the more Yeah, they did the legacy one with the legacy Yeah The new Tron, yeah, yeah, it's the new Tron so Yeah, so Pits the along the idea of March is like yeah, you got to have it stick on your back Which is funny because when I told Gavin that that was the very first thing he said is like, oh cool Are you gonna make it stick to your back? I'm like Yeah, so so far here's what we got on the inside everything's gonna mount We're doing the pool at dual or the swap filament color techniques So start off with that diffused color, and then it goes into the black. So the lights should shine through Yes on the inside will have the Battery will do the RP 2040 with the the prop maker feather wing and then We're gonna have the magnets mount on the sides here feather wing prop maker all that We're here and then everything just snap this together of course and then the magnets We'll do like a little harness that we did for the dragon wing or the butterfly wings. So Yeah, you gotta have the magnets Yeah, that's all the ones that we see that have been built So they all have you know the cold the accelerometer, you know noise changing the color changing because of circuit python Of course, all that's now easy. So of course, we got to level it up I just haven't it stick to your back because no one's done that. Yeah Should be cool. We'll go scope it out tomorrow. See where we can actually film if we're even allowed to go in there before the reservation to start try to make a Lot of prop All right, thanks for the user. I'll be watching your socials because you usually have some good On the ground with new footage. So I'll be watching that so fun All right All right How you doing good? How are you? So this guide went live last week by missus show. So I wanted to come by So this is an octoprint viewer with circuit python And it's using mqtt and the mqtt plugins in octoprint to Send messages to octoprint over adafruit.io. So right now I's had a print finish. So I can press the Front button and this using the reverse mount esp 32 s2 tft and then if you add my screen Um, yeah, and then for the folks who are new to a lot of this stuff What is what is octoprint? Is it for only printing octopus? Or can you print other things? I mean it's preferable if you print octopuses, but like, um, it's a open source. Yeah it's a open source 3d printer manager That allows you to remotely monitor your 3d printer. You don't want to sit around for eight hours So it's pretty useful and you can yeah remotely monitor and you can actually use your 3d printer In a reasonable way because the speed-ups that we do that's not real time Um, it actually takes eight hours sometimes. Yes. Yes, exactly. So, um, and there's really awesome documentation on how you can communicate to octoprint over mqtt. So right now you're looking at kind of the live view of the printer and if I press this button on The tft it just got the ping and now the hot ends heating up to preheat for a print And then I can print I can um press rather this top button And it will get another uh ping and so now the hot ends off And if I press this uh bottom button, they'll reboot octoprint remotely and while i'm printing I can pause the print resume prints and cancel the print, uh, so Um, and in the guide I document how you set up all the difference feeds in io and in octoprint itself So if they communicate to each other properly, that's probably the hardest part So if folks want to check that out, uh, they can build up for what they need That's outstanding. All right. Thank you so much, Liz. Yay Making prints to make prints. Yes All right next uh pitch dragon What you got going on this week Uh retro hardware. Yay. Yeah, um You know sometimes like I I especially like there's a certain kind of gadget where it's just like It just captures a time and a place And this object and they just they all belong together like like I could show you this cassette tape And you're just like early 2000s, right because yeah Like sony walkmans like a lot of these things fit together they it's like oh, yeah It time and place right and so I I I found this this thrift stride and it's like I got to have that It's this little little boombox made by tushiba. Oh my god. That's so cute. Yeah, like I can see like corey feldman holding that right now Yeah, but but um anyway This is wacky, but anyway, there's a little latch on the back Yeah What happens is um Little walkman popped out dude. It's like a transformer That's amazing Powerbook duo earlier right same idea, but even even sillier than that is um, man I hope you open it up and there's another one inside if you want to listen to radio There's a special cassette. This is yeah, this isn't like the magnetic, you know, like the um Car adapters be your car. Yeah, there's like car adapter things if you know Special radio receiver cassette a special contact here and then inside the cassette player these like one has to go in the other in order to listen to radio and Like you were right today looking at this. We just be like That is so stupid. Why don't you just make this like one millimeter bigger and put the radio inside, right? But you have to think about the time and play you couldn't and not just that but Music stuff is primarily marketed to teenagers And we think about teenage popular culture japan 1980s And it's you mentioned transfer. It's all about robots that click together And so that's why there's this ridiculous nesting of things. It's so cool. It's so fun I love it all in one But that wouldn't be cool that wouldn't appeal to yeah, I don't even like it's just satisfying It makes the clicking this is like I'm expecting like sound wave It's a megatron and like this like little like robot cat to come out of it or something But I haven't figured out yet though. I haven't cracked this open yet. It's in bad shape. I don't think it works I just got it because yeah, you know just the kind of nostalgia thing There there's a antenna on the outside here for the radio But I haven't figured the path from that Yeah, how does it get all the way back to what I'm saying? Yeah, it's the center adapter. I don't know because there there isn't like a You know, there's a head there's a headphone and I will say that a lot of FM receivers do use the headphone cable as the antenna because It's a it's at a higher enough kilohertz that it doesn't interfere with the audio But the wire itself is going to pick it up. You know, it's funny. It's probably somebody did by accident They're like, why am I picking up, you know FM radio? Oh, shit. It's coming in through the headphone jack And then they're like, wait, I can just use the headphone So I actually think that it's the that goes into that's capacitively coupled into the headphone input Because that way also when you have when you're listening on the go Like not with your boombox because you're in class You're an algebra one And you're listening to radio instead of doing your work um yet that headphone would be Um the matching one now what you need to get is there's like so many had the ones that Like clipped onto your ears. Do you remember those? Yeah, remember that? Yeah, it was terrible Yeah, so anyway, I'll want to clean it up or whatever just yeah But when I do that, I'll yeah, I'll I'll look at where the antenna goes because that was just weird to me that it's like outstanding find What a great. Yeah Yeah, it's apparently even like not working. There's still kind of collectible. But yeah I just I saw that and it was like, oh my god, that is like 1980 You know distilled down into this this thing Very cool Very cool. All right. Always bringing the good stuff Excellent, um if you could after you get it cleaned up if you make a little video clip Of it and then have it opening and closing just that sound and just the look of it That would be really nice that that little trunk. Yeah, I just would watch that on loop for a while They made these in different colors too and some of them, you know, you have the player and the speakers Are both of course red, you know, the japanese consumer electronics had the whole red lacquer look. Yeah Um silver white, etc. So this is like this weird mishmash, you know Not paired up one, but uh I've seen pictures of the the matched units and it's like that is so cool. That's nice. Oh 1980. Yeah All right. Well, excellent find so cool All right next up jp What you got going on this week? Well, I'll tell you now. I'm thinking about um thrift store tourism and why I'm not traveling up to Phil B's neck of the woods. Yeah, we got good thrift stores down here in southern california, but man he gets the good Yeah, I'm actually kind of impressed. He'll be like, you know, it doesn't matter all the time But every three months you come by and you're like here is this ancient thing that like it's ultra collectible It was like five bucks at the thrift store. I don't know this magical thrift store is I hope like it's a sign for I hope in 10 years we find out that phil b is really actually just breaking into like Sunnyvale houses and like getting people's like cool electronics that they've stowed away for decades Yeah, there's just a storage center for a museum that's Wanted man running off with like old sony hip top lot, you know laptops and stuff Yeah, or time travel. You know that time travel still ages the uh crappy plastic All right, so hey, uh, I have another update on my favorite topic of late, which is these cat pianos um So this one is the one that I have just tapped into all of the buttons and keys on it and you can see over here I have a kb 2040 on a little uh perma proto board and some ribbon cables so it's a matrix of uh six by eight that basically Every key and button here other than the on off switch, which is an actual switch And these four here, which I still haven't tapped into they're directly on the sort of main pcb of the thing But everything else is on these ribbon cables Um, and now I'm able to Code them not only to play MIDI notes, which is what I have these doing here Which is significantly enhanced from the original cat piano sounds although now, so I've got to find a sample of them Now. Um, I'm running it through in this case usb midi With the little camera connector kit we sell to an ipad And there's a fantastic synthesizer app from audio kit, which is free and open source It's called synth one and they use that engine for other stuff You can use their engine and reskin it and sell stuff. They're really cool company and Really great fully featured synth and it has really nice MIDI implementation, which is kind of rare to find what I really wanted Which was the ability to change banks and patches which are the presets So these things always come with a bazillion presets and you go and pick through them and then play them Well, what I wanted to do is use these little cat paw buttons, which actually this side is what it did originally So piano bells meow organ and banjo picked among the five voices built onto the thing If you watch my ui here, you can see as I press these buttons It's changing a bunch of stuff and more behind the scenes. So now I can pick some other patch that In this case happens to have a little sequence associated with it And so I've I've programmed all 10 of these buttons to pick different patches And I've also set this little play button to actually start and stop sequences so I can play this patch Just as individual notes Or I can go crazy and hit the play button and now Cyberpunk kitty piano time. This is cool. Which is what phil b may have been playing when he broke into the cool electronic Center, I'm not gonna say I know for sure But I have my suspicions and then there's other buttons. There's a stop button and like a red cat button Yeah, these do I'm open to suggestions. I don't think I have those to do anything yet Stop button. However, this is kind of a cool one when you are playing stuff on MIDI instruments especially if you're you can send this out to like lots of synths or computer synths or hardware software synths Over different midi channels all those things are possible Sometimes a note will get stuck and so you'll you'll let off the keys and you're still hearing a note In which case you hit the boop on the cat here Which says stop on it and that sends out a thing called midi panic Which is one of the best midi messages a midi panic sends the midi note off message to zero through 127 So it just says if any note is playing no, you're not anymore. So That's the great use I found for my my stop button on that weird keyboard that we Yeah, it's like and then there's a microphone. Um, are you gonna do anything with that? Is that for like cat? I'm open to suggestions on this. Uh, so on the um, one thing is they get a great mechanism for retraction on here because You know slam play that all like that's even more fun than the piano is just doing that So it's really rugged. Uh, I was thinking of JP clearly has had kids because you can tell This is an excellent keyboard now. I mean like this does kind of does everything Yeah, it's not but yet is now The the the use of it for midi stuff. Not bad has no knobs, but it's pretty great for a lot of new stuff Um, I got one suggestion from someone to put an accelerometer. I think c grover said That's a good idea and things or other Did it actually do voice changing? You know, that's a great question. It is, uh, sending this through So it just sends it through its own little path here It's a separate interface because it's like there's not I don't I don't believe that you could Sample from it, right? Yeah, so that's a great question I wonder if we could have that working as a sampler into uh into another synth or something like that So, yeah, it's a good question. I have the other one which I'm putting through guitar Pedals and stuff. So I might leave that as a mic. Uh, maybe add a kill switch to it so that it can do feedback This one might be neat to like put the usb port in there or who knows what so I'm Suggestions. I'm still tinkering. Um, and this uh while I have this running usb midi right now off of my kb 2040. I also have a Uh, 3.5 millimeter trs jack, which I'll mount in there and that means you can plug it into any, you know, 1987 yamaha synthesizer whatever old thing new thing any classic synth that uses cereal Uh, you don't have to use the big din five midi plugs anymore. You can use trs So this is wired up for that as well. So you have a bunch of options to uh to use this as a Crazy midi controller very cool, and you'll be uh probably showing this off on your show Yeah, I'll be playing around with this and the uh feedback one and and uh some other stuff on the show tomorrow So come on at four o'clock eastern time tomorrow to see what kind of kitty, uh synth stuff is happening and and more All right. Thank you so much jp All right next up. We're gonna go to flying things and then mouse flank things. Hello. What you got going? Oh You can't hear you can't hear you flying things. Hello. Yeah I've made a fursuit head that has Oh nice ease as a splicer and let me turn on the ladies I have it controlled by these paws with That's a theme tonight And foxes all cats and their capacitive touch so let's see if I can don't juggle all of here Oh fun, okay, so when you touch them. Oh nice, so they change colors. Yay rainbow. Yeah. Yeah They got blink Oh, that's really cool. And then that's see-through so you can still see through it. Yep. So yeah, this is also just magnets on top You need to really jump with the um with the blink animation because it's like not You know, you have to map it to the pixels to make it Oh, that's really smart with the magnet so you can get at it and do things and also Yep, you can see through it, but it does do a really good job. Okay beautiful. Yeah. Thank you I got a fan in there. I don't know sure. Well, that's Yeah, you can see in there. I got a little OLED. Oh, wow. That's a full computer heads up display Yeah Okay, cool This is great. If um, if you ever post anything online about it, let us know. I'd love to put it up on our blog Yeah, great work. Thank you. A little of the simplicity, but it's like it's it has a lot of Evocative emotion to it. You know what I mean? Like the blinking and the colors The counts are coming because there's this is too cool for us. Yeah Here in the background here. All right. Thank you so much. All right. Thank you so much flying things All right mouse place out Hi, okay. I'm back with my modular synthesizer, which is almost done But I'm still working on this one module, which is a lot of work It's a prototype for a digital FM voice module with a feather RP2040 and I've added some stuff to it since I last showed it off Some of the stuff you can't see is firmware. Let's see Yeah, so it's doing full six operator dx7 style FM synthesis now, which is great I ran into some issues with the off chip flash memory is too slow But I've got it working finally and I've added a rotary encoder and a Adafruit OLED which is in a display which is in a plastic baggie because the pins on the back were shorting out against us Yeah, and so I can now I've now load patches in it and That's cool That is bells. Oh nice Yeah, so, uh, that's where it's at. It's it's uh It's it's gonna be finished in a few months or years. Yeah Well, I finish it. Yeah, when you can keep working on it. All right Excellent project and excellent work keep coming back as you add more to it And uh, we have a little bit of a musical theme tonight. Yeah, introduce All right, JP. Do you want to play us out? With your let's see if uh, we could get into Here you go Let's see we put them on the spot. So I don't know No, there's no audio coming out. Yeah, no audio. Oh no, here we go Wait, here's the spooky one I kind of love this this show is this show is free everyone. That's the most meowsic one I could find on Why pay for drugs when you can just watch this show? Yeah, I don't know why didn't you cross charge? I know free entertainment This is way better That kind of matches, uh your dragons, uh That's what's playing on his box. Yeah All right, that's very cool. All right, thank you so much, Stevie. Thank you for bopping. That's our show and cell We'll see everybody next week. I think next week. It's JP hosting and then after that it's Liz Thank you so much everyone for making this the best half an hour over a week every single week We do the show and tell us of 30 p.m. Easter time every Wednesday and then we do asking an engineer We're just gonna start in just a few minutes all the cat sins We'll see cat heads cat sins the most popular cat sins program on the internet. We'll see you later. I know ladies Bye
