 Lady Ada, what is this? Hey everybody and welcome to show and tell it's your og host miss lady Ada. Mr. Lady Ada Here at the interface factory in downtown, Manhattan's where we're broadcasting live some weeks We have a known Pedro or Melissa or Liz or JP or our Florida cruise. Okay. We just talked to okay But they are Hunkering down as they say to get through this storm. So they'll be back next week Pedro not here this week. Yeah, they're okay. They're okay. Everyone's all right We're checking in on them and we'll make sure we'll continue to so and for all the folks that are In the Florida area and more We are hoping Thing misses you So, okay. Okay, but let's kick it off starting off with jebler and jebler keyboard. Hello. Yeah So I mentioned a couple times this Cash of retro computer stuff that I got and I got this handy personal computer keyboard from a friend and A guide went live this week in which I converted to use circuit Python so If you just maybe come back to here for a second a little adapter With the special each keyboard is different and has a different connector on it So you got a source the connector from digi But then you just got like power ground reset clock data Into the cutie pie and load some circuit Python software and you've got a totally usable Adequate keyboard Completely adequate. It's completely adequate. There are some weird things. There are some weird things about this keyboard It's completely okay Here's a detail of the grind which happily it just cleaned up with soap and water Some people go through chemicals and hydrogen peroxide to clean up their plastic But as I took it apart inside, it's got these really wild key switches. Whoa, that's not standard And yeah, so like the key switch plunges over this lever here to give it a good amount of travel But really it's just activating a micro switch and then this LED here actually goes with this here Which is the num lock key and some weird location And so these old keyboards, they're just wild and you can't get these switches anymore So it's lucky all of mine are intact. This guy was made by Fujitsu for Tandy And it's got an 8048 microcontroller in it, which I assume was programmed at the factory can't be read out or I mean, they definitely didn't have flash at the time. No Yeah, there is a detail of the weird Light num lock light again, and here's how it looked after I cleaned it all up. Oh Good, so yeah, it's a it's a lovely keyboard. I think you really could use it as your everyday keyboard You've got alt. It's here somewhere, and you can Patient key or whatever you've got control and shift and tab and escape and all the good stuff Another weird stuff is like here's the the pipe key is on numpad for There's not a pipe key. I don't know why It just Yeah, this is pretty standard. This is you know everyone and what's in the top right? Is that like a roller was What's that in the top right? Oh, those are the feet. It's got these little feet. Oh From the top. Yeah, it's actually kind of cute little feet. Yeah I'm yeah, they're spring loaded inside and like everything else. It was intact, which I feel like is miraculous So, you know if you just have to have one of these I'm done with the guide make me an offer Because these are rare, but Bay I need pio on the RP 2040 right using pio because it's a clocked serial protocol Which normally circuit Python would really have trouble handling that other device, you know driving the timing But with the pio Peripheral it can buffer up to eight characters or eight keystrokes before it gets lost. So it works really nice Yeah, so that's enough about keyboards. I'll just talk about one other thing Which is Wi-Fi support is merged for the pico W Coming beta release. So a big thank you to everybody who tested and who just shared their excitement about getting to work on that So there are some things we have to investigate and finish up But like I put it through the paces with over 60,000 HTTP requests and it just kept going. So yes, it's really it's really something I'm really thrilled and I'd invite you to try it out if you've got one sitting on your shelf Yeah, maybe something discord can pop the PR so we can see the to the progress I do want to mention Jeb was working extremely hard on it and there's bugs that we're discovering some which are not in circuit Python Also a secure SSL TLS support is not ready yet. We're gonna be working on that in the next couple weeks So we're investigating how feasible that is We're gonna get there but for now as long as it's a non TLS SSL connection. It should just work Yeah, so yeah, I will drop the link once I sign off and you know, y'all can let me know how it works for you because We think it's good Talk to you later. All right, JP Hey guys in your Tower of Terror. Yeah, so I think I've shown this but it's been developing and it's got a name now This is Darth Vader's Darth Vader. Yeah Darth faders. Yeah, and it answers the question. Why shouldn't I have a weird vaguely threatening ominous sci-fi Crop thing that can move on my desk The answer is you should and so these are three motorized faders and three printed enclosure I made for it and now I have one of our really easy to use STEM a Qt break out rotary encoders here and so I can select individual animations from These poses or positions that I've set Like a sequencer So whenever you just feel like looking at it in a different spot, you can flip that over These also are always measuring where they are. So they they're like, hey, no stop that I'm going back to this position, which is kind of that's regressive there. Yeah You can also just decide to have it kind of breathing at you like Darth Vader and running through them all the time So I just clicked the rotary encoder there Which is a push encoder has a little button and now it's just gonna every four seconds go to a new position hang out there move to the next Doesn't do anything other than that right now It's just purely ornamental, but you could of course have this sending out USB stuff MIDI control stuff Volume things if you have an application that'll that'll read in some sort of HID Button presses as or media presses as a volume controllers it you could extend it But I just have it be in this kind of cool weird thing on my desk. So That code just went into our learn guide repo last night and or actually this morning And I'm gonna be working on the guide for that so people can build their own set of Darth faders This is the Enclosure for James Earl Jones voice to keep retired doing And he's like I guess the way it worked because he whatever the rights are and how he thinks with his voice It's licensed or now it's part of an AI company that can continue to do the voice. It's all Contractually bound, but this is the server that they should store it in Maybe you could circuit bend them and stuff like that like Yeah, I in there that holds the AI for the voice. Yeah, all right. Thanks so much JP. Yeah, I think JP All right, Liz we're gonna ask you to go now and then at the very end play us out because you have a very special musical project this week Yes, so there is a game that kind of went nuts on the internet called trombone champ and this is a controller for it It's using a cutie pie RP 2040 kind of via USB and then a neo slider is moving the cursor up and down And then an arcade button Sends the toot because you have to press a key to actually play the trombone But you slide the mouse up and down to do the pitch. So using this it's like you're playing an actual trombone And actually I don't have it hooked up right now to the sound because I kind of in demo mode because I get nervous having All right Actually does move your mouse over to click it re-clicking on her screen sending mail Yes, so this will be this guy will be live shortly if folks want to make their own I know a couple folks have been making controllers with this one on I think pride just a little bit simpler approach Literally moving your mouse All right, so we won't have you played out Maybe you'll have a video for the will. Yeah, yeah All right, thanks so much. All right, thanks Liz Alright, Philby paint your dragon what you got going on this week. Hi. Um, I have here a mini disk Which is a um, this was a music format from the 1990s Didn't really quite catch on here It was big in Japan, but not here every science fiction movie had this is like how they're gonna play Yeah Required to have a yeah, this is all how we have Dana was like you like shove that into your head or something Yeah, Johnny mnemonic strange days the matrix they all involved Minority report Yeah, so it's a little smaller than a three and a half inch floppy and there's like a cd comparison It's not I think everybody's heard of these they're not super obscure But anyway, the cyberpunk thing a funny thing is on on the cyberdeck PCB which But there's there's there's little optical discs in the back That cyberpunk thing. Yeah, so um, I Was thought these were cool and wanted like a recorder But not like so much that I was gonna go spend 50 or 100 bucks on eBay plus shipping to get one And I lucked out a couple days ago at the thrift store I Didn't work though 10 10 bucks, but it was you know, it's as is It's a crapshoot whether or not it's gonna work and it did not work but brought it home and But it was such an easy fix and that's I think one of the cool things about this electronics hobby is You know everything comes with the warning, you know, no no user serviceable part But yeah, you learn about electronics and you know which which end of the dragon you can safely pull on you know, yeah, so That's the cool thing with this hobby is It has dividends and so I was able to get this this working And I don't know what the moral of the story of what was like a fuse or was it loose cable or what was yeah It was a cable just needed reseated. I think it was right oxidized. Just You know what that's that, you know, it's solid state does 90% of the work, but good work I think when you can repair things Because there's so many things getting thrown away, but when you can repair things really unlocks your Ability to have fun with all the stuff that's out there like you get to you have a better different experience because not only Can you purchase a thing but you could fix the thing and you have a skill and you can combine all these things together so it's like you have a richer experience in your day-to-day because everything you have a lens that's like Oh, I wonder if I can fix that build it do something turn it into something else And if you can't fix it, you know, it's like who cares if enough that I don't have to feel bad about it Yeah, yeah, you rescue. I mean you like saved a life here and many this life Yeah, yeah, it's like CPO that works. You're like, wow, that's cool. Exactly. So anyway It was just one of those lucky finds and it worked out And so anyway super cyberpunk. It's okay. So what is that made its player or what is it? There is a recorder. They did make pre-recorded mini discs And certain, you know, there are play-only Boxes, but this one can actually record if you have a recordable mini Can you re-record is it or is it one magneto optical format? I know that if you have a recorder versus a player. Yeah, it's a re-recordable Magneto optical disc. Wow. I don't even remember seeing a re-recordable one. I remember I've seen the you know one-shot music ones, but And that's the same for those same format used by the Sony Vita, right? Oh, was it or Sony did make a lot of players. I don't remember no recorders, but they I think they're the video game system used the mini discs Thing and it's this weird slightly triangular enclosure, but is it the same? It is not it is it's not Okay, like I yeah, okay. I love doing that Having that was that was Sony duo plus pro Lamore. I know how can I not tell the difference between like the three Look, I know that I'm shooting that in a laser desk right that I know They just like need an optical not Not like laser optical Interesting, right. Yeah, the play-only ones are just standard laser. Yeah, but I don't have any of those yet Next up. All right, excellent fine and good to show folks. There is an entire world Waiting to be unlocked and puzzles to be solved That are otherwise gonna get thrown in the trash. Yeah, well, I can send you some UMDs If you I think I have like two or three they came when I when I bought my PSP it came with a wow Give me two of them. All right. Okay. Next up. We're gonna go to Travis and then we will go to Paul Hello speaking of old electronic trash I've got another high voltage Thing it's called I call it an eye to an eye tube And it's an oh Yeah, I've seen some of these before this or these are neat. Oh, yeah Yeah, it's the viewfinder out of an 80s video camera. Yeah We were we were willing to do anything. Yeah to get like because it almost looks biological. It's like this is This is the eyeball Yeah, that's cool. What a nice build I Love the casing Yeah What's it playing on the screen? It's an eyeball. It's a it's my friend's eyeball. Oh nice. Oh, there it is. Yeah That's why it's an eye tube. Yeah, excellent And then it's got a little charger on the back Now everything's reversed. Yeah, right. Yeah, and I chose the light pipe for the first time and That was hard to find It's actually The light pipe light-bright material or like fiber optics because the charger You know the LEDs are facing on the board on board LED and I needed an L I needed a 90 to get it on the back And so I had I was trying to find a light pipe I can't find a mini or had to find some old ones from like the 80s That would be an old stereo or something. Where'd you get the viewfinder from? the viewfinder I Got a broken Camera video camera off eBay for 10 bucks shipped sweet and This is the viewfinder. So it's like one inch The ten bucks and apparently exactly what people are willing to pay. I Think the two below is worth ten bucks but Yeah, so like back then they used to CRT if it has a viewfinder and All right Well, this is awesome if you can post up any info for people who want to replicate this type of project If you send us any links or photos you can send it to pt at a to fruit comm and we can put it up on the blog and everything This looks great. Okay. Yeah, and then I ended up using an older pie because they had a composite video out on them Right. Yeah, yeah, they do have them out, but it's hard to get to you know, you when they come from the audio jack They still have them exactly, but it's like you need to get the food off And it was I had actually done that video looper The other tricky part was getting to seamlessly loop and I use the OMS player for that But it's really actually I did that a long time ago that video I part for another project and then I then I Got all I've been getting all into this high voltage stuff So I knew I had that little player looping eyeball laying around and I go That's cool All right, well, thank you so much. Excellent project. Nice work Travis. It's awesome You are you all you need is a couple of laser discs and you're ready for the cyberpunk future Hey Paul, what's going on? I Have not one but two podcasts now that I talk about circuit Python on really. Oh, they're doubling We're doubling up and double the hosts. I'm doing this one with Todd bot Todd Kirk from the circuit great Yeah, lovely. So where can people find out about these? They can search their favorite podcast app for the bootloader or go to the bootloader dot net And we've got all the links there to subscribe in the apps And we just launched our first episode on Monday talked a little bit about to know and what I you know What a great open source project that is yeah Todd shared a little bit about camera support on circuit Python And then we talked a little 3d printing and a couple other tech news type of things All right on that's fun. Well as you boot up bootloader Let us know we'll add if you know there anything with Python or circuit Python we'll get the word out in the newsletters and Some blockers you can set it to Ann and I and we'll help get the word out What is the what is the topics that you're like obviously circuit Python show a lot of circuit Python stuff What what are some of the topics that are going to be in bootloader? Anything from the tech and maker scene so it could be circuit Python one week could be micro Python the following week It could be Different different stuff. Yeah, I'm glad you're doing this there isn't an audio or even video only there's you know There's maker update But it's definitely a different type of format. There isn't like a long form Interview or getting know some of the makers back in the day at make magazine Bre and I When we were doing the maker podcast We were doing interviews and having some stuff But it's something that I really think getting the stories of the makers out and talking to them and understanding like oh This is not just like the end result But how they got there and like oh like how did they figure out? They wanted to do this project like show and tell is a very small version of the philby's like went to the thrift store I got this thing and here's this piece of tech and you kind and you know the the previous person Tavis Like oh I had this eyeball footage and this is this thing and really helps people discover all the projects That they might want to do but it's not just like here's a photo and it's too intimidating And I don't know if I'm gonna learn all those skills like oh no Here's a story From someone that I can relate to yeah, you should have Tavis on the show that I think people would love to see You guys guys connect up because everyone loves high-voltage The folks around show until because you know we only each week we're like okay five minutes go go go go We don't have time for really during covid peak covid I should say or what actually whatever it like whatever two years ago Yeah, we we knew that having a long show until would be helpful for folks because a lot of folks were at home We were the factory at night or in the morning or different parts during the day But we knew a lot of folks were home and we wanted to find something to bring people together and just people showing their projects and sharing stories You know help we know and you know how to handle stuff or what was going on so more stories from makers and I've got Lane on the circuit Python show next week who's got some really Python products from a The joy pad to Lots of shiny lights that we talked about. He's got a couple lumens. Yeah, there's a lot of cool stuff that Shut off recently. All right, Paul. Well, thank you so much for Doing all this and spreading the stories and information about all the stuff going on in electronics It really is the best time to be doing electronics And they can almost kind of get some parts once in a while. Yeah, that's changing It is getting better like we've started to as one content creator to the other We started to shift from chip shortage to real world You know eventually I guess will when there's too many electronic parts will have like Part flood. Yeah surplus surplus wars. Yeah. Yeah, we do have some time Yeah, I'd be nice to have that but anyways, all right. Well, thanks so much. Paul. Good to see you Bye All right, everybody that is our show until this week. Thank you so much everyone for joining us for here every week Some 30 p.m. Eastern time. Thank you so much everyone for showing sharing your projects Please come by show some of the things you built some of the rest of the things you found some of things That maybe you have in the attic that you're like, oh, here's a cool old thing All these things are welcome and all folks are welcome. We'll see everybody in a few minutes Ask an engineer starts in about five minutes or so. Bye everybody. See you in about five minutes
