 All right, lady. What is this? Hey everybody and welcome to show and tell it's me Ladyita with me. Mr. Ladyita. We're broadcasting live from downtown Manhattan the Itford factory that's all behind us You can see the machinery and the kidding tables and the fabbing tables and the all the stuff that we do here to make electronics We make stuff. It's it's it's a party every day right now It's a little quiet because everyone's home, but that's why When it's quiet, we do show and tell which only check in with folks from around the makerverse It's just kind of like the like Marvel cinematic universe, but it's the maker makers and many rumors To see what they're up to we have some Adafruit folks. We have some people from the community coming by I see some Blinkies Yeah, already. I'm excited. We're gonna be here for about 20 minutes If you want to join in on discord, we post the chat I use a video camera come on by and show up what you're working on JP what you get going on this week I'm entering the makerverse. Yeah, you're tuning in from Earth one Marvel doesn't have any mime characters. Do they do they have any mime characters? You know, there's probably an archive of like gambit DC, right? I don't even know if Remind me Okay, my gig once yeah, yeah 20 something years to admit that but there it was the first social media it's fine so speaking of Marvel We saw earlier a tweet from Microsoft and Marvel about the Black Panther Wakanda forever Team up they have for making And more said, hey, would you check this out and maybe do something with this? They've got some a cool tutorial you follow and some assets that they've made for the game And so I made my own game using their assets and in make code and I'm running it here on a pie gamer And I was really excited because it's been a while since I dipped into make code arcade They got a bunch of cool new stuff such as Check out the parallax Multi-plane well background mid-ground Stuff going on there. It's very easy to set up The art tools have had a bunch of improvements to them Let me try to not get killed here and shoot some shots. They've also got sprite scaling. So these whoa, I died These sprites are actually originally drawn smaller, but they've been sort of pixel double scaled up Which is really cool something so a lot of really neat features And so I'm gonna develop this a little further and add some hardware to it The more had the idea of maybe adding some neopixel strips because we can plug them in On these JST connectors, maybe make like costume gauntlets that light up while you're playing the game So you're very immersed And that's if you can shoot maybe they then you're you can see the LED shoot on your Make a video game like this for hardware with just blocks It's amazing. It really is. I mean, yeah, I don't have a share right now share screen up of what it looks like, but it's I don't know a couple dozen little graphical blocks. Yeah, plug together. It's not much It's all it's all basically the logic of how would I do this? There's no no Tax to remember which is really a super cool thing about make code and make code arcade in particular because you've got a Simulator right in the web browser. So you don't even have to put it on your hardware. You can do it right in there But but once you get on hardware actually runs a little smoother if you look at this this parallax stuff the No, we're making a joke. It's like they imported mode seven from the SNES Remember when I when I played Final Fantasy 6 and they had that part where you like are moving to this like castle and the Background moves separately in the foreground and I was just like oh my god. It was just yeah, it was amazing incredible So that's what we're gonna. I'll be looking at this tomorrow on my show and I'll put together a guide once it's all All done and people will be able to make their own and you can run it on a bunch of different hardware to this Bunch of different hardware that you can plug into make code arcade and then take it handheld. So this My favorite Jeff what you got going on? I have got pixels today. So like 11 months ago. Lamar teased this board called Scorpio and I have one of the prototypes pardon me here. Let's see. Where is it? It's here somewhere. I'm bad at a small. It's there It's it's a feather but coming out the end are eight different connections for Neopixels And so I've been getting the circuit Python code running and so here we've got eight LED animation comets boy, I shouldn't have moved that camera Eight LED animation comets running at about 40 frames per second. Wow So one of the things that's cool about this is we've kind of upped our game in how it sends the data out It's sending the data for all of the strips simultaneously and it's Sending it in the background. So you send the command to Refresh the display and then it immediately returns to your circuit Python code. Yes, it's thanks to the DMA PIO stuff that you added Yeah, and then so then you're calculating the next frame of your animation while it's actually going out to the Neopixels and it's seamless and there's no tearing and it works Really great. So we've got the library It's gonna appear in the bundle tomorrow and you could actually use it on any RP 2040 as long as the pin numbers Like the GP numbers are sequential. So like two three four five six seven eight nine or 16 to 23 whatever it is. They just have to be sequential. So you could put this on a good old actual Raspberry Pi Pico You could maybe put it on a feather. I'm not sure we do that they are I didn't make it so the feather has That's why the GPIO numbers don't match the D numbers. They are GPIO. It's like whatever they are They're eight in a row because I expected that we might do projects like this So yeah, maybe when we show off this library, you'll show like you can actually just plug the Neopixelate friend directly next to the feather on a breadboard and it should just work Yeah, so it's really cool but one of the things the Scorpio has is the level shifter which just makes it more Robust and you know according to all the data sheets, but I think we've all experienced that Neopixels work on mostly any GPIO pin Yeah, so anyway, that's what I've been up to the code is out there and Coming up. I hear the product might even come out. Yes, you know, it's a Scorpio season. Yeah It's a Scorpio season for like another couple weeks and for the folks out there There has been a bit of a drought for not only chips But like new platforms where you can do interactive light installations like level shifters like you can't get those. Yeah, so We expect a lot of folks to take this To all sorts of places and do all sorts of things. I don't even expect so it's gonna be really neat All right, and there's a floppy disk here for no reason for size. Well, I mean you're doing retro stuff There's just fun out of everywhere. There is. Oh and I'll just grab this keyboard that we talked about last week So no, no, this is the wrong keyboard. This is the Klee go-at-em keyboard. I'm a total liar. I still don't have that Wildcard key that's wild card keys cool, but it's not as cool as help. It's not as cool as help So, yeah, I'll I'll come back and if you got all right and come back to me Yeah, we might do that. All right. Next up. Let's go to Liz and then after Liz we're gonna go to Dan W. Yeah, okay. All right, Liz. What you got going on this week? Hello So this is a wreath that I normally have on that's in my apartment door It's a print that's on thing a versus pretty popular And what's cool is you can like put different things on it. You're so adorable. It's like mega Lego Yeah, and the spring I do the flowers up and then when it gets so winter I put the little hollies on But in the fall I feel kind of like weird I don't want to put like with your Christmas stuff up too early because I don't like to do that before December So last night I modeled up little maple leaves Printed to so far and I'm gonna make this now a fall leaf For fall now so and I'll put the model up if folks want to print it because I a lot of people have printed this thing But okay a little fall 3d printing project That is a nice design Does a mini fig live there? Make my neighbors think I'm even weirder than I am All right, all right. Thanks so much Liz and just a programming note. Liz will be hosting show until next week Thank you in advance. Of course, of course. Maybe we'll see you around. All right next to Dan W and assistant. Hello. I think Dan She's the engineer. Yes, what you got going on then? So we've been playing trombone champ recently and we saw the Trombone champ controller. Yeah, Liz did that project. Yeah, I saw that. Yeah, cuz I yeah, but I just wanted to use something with Like a time of flight distance sensor instead of the the potentiometer And so I went down to the dollar store and got one of these like little foam dart guns and just gutted it put in a Qt pi rp 2040 and one of the time of flight sensors and then there's a two-way switch so it's you can or a three-way switch rather so you can either turn it off or Switch between like closer is higher or farther is higher depending on how you want to do it But yeah, and oh Yeah, that's some And it goes very fast and with the distance sensor you don't have to worry about it like wearing down if you go crazy with it And I made another version with What was this the trinket M0? Just to you know, it's a little bit pared down because there's a bit of a space Issue. Yeah, those are all chips. They they barely can they you know, you can get them to work But they're they're now getting close to five seven years old. Yep, but it's still works and Fit perfectly in the little in the little thing. So we've been all right Crazy using Python or what are you coding it in? Oh, that's all circuit Python. Okay. All right, cool All right, I'm gonna add the creator of the guy to this Liz, what do you think? All right, Liz? That's awesome All right, I'm standing all right. Good work. All right. Thanks, Dan. Thank you. Dan's assistant. All right Next up we're gonna get a mouse and then we're gonna go to BCG mouse Well, yeah, so you got to get lose back again because she of course is Showed me how to make these. Yeah Except the third learn guide The nudes that you can't actually pass the signal through them. It just shows you what the voltage is. Yeah, and I thought I Just want the signal to go through them and you know, they said it couldn't be done They said it was crazy, but they said they said you you're a madman They said Um, actually this nude here is passing an audio signal Really? How's it doing that? Well, it's doing it in a very obvious way that you just took the nude up to the tips of the two plugs and there's a Inside the jacker is a current limiting resistor from the tip to ground But if you know about diodes, you might suspect that it does something to the signal on the way through. Yeah So I can I can demonstrate what it actually does to the sound when you put it through a nude Whoops, hang on. We've got an emergency alert For sometimes when you have like a synth going it sounds like that you're like that's actually my sense. Yeah, I could yeah, okay, so Um Yes, so I can show you what it sounds like. So I've got the same Audio signal going through two patch cables here. One of them is the nude. Yeah, I'll play the straight signal first to the regular cable Sounds like this might have to update the guy. Okay, if you can hear it, I hope Yeah Okay, and I'll just Change Got the mixer here Okay, and it sounds That's that's what it does We've got a voltage drop, but And it's rectifying the you know bottom half of the way So like that You know, I think you should like, you know, there's ways that you could make this work It would just be kind of funky. You'd have to have another wire to have to be hidden But I mean, I does do something, you know, you could sell it for $500 on eBay now You'll be in refurb.com next week So, yeah, I mean it adds character that you know, we don't call it distortion when you're actually making a sound Yeah character. So it's a compressor of sorts. Yeah. Yeah, so it sounds more like my way folder Well, it looks really cool. That's what counts. Good work mouse and Liz if you want to update the guides for this like fun hack maybe Maybe that'd be a cool one that folks can do that looks like a scene out of an anime When they're lit up like that. Yeah, all right. Thanks so much. Yes. Thank you, Matt. All right. Next up. We're gonna go to VCG Oh VCG what you got going on? Hi, can you hear me? Yeah. Yeah Hey, so I'm working on a keyboard project. I got a kinesis advantage to keyboard and Actually, I saw your guys is The kb2040 the the pro micro yeah fun and that was actually my favorite my favorite little board as I was like Oh, I gotta start using but I and so I had a existing controller and I'm gonna try and See if I can bring my other camera You know try screen sharing. Yeah Yeah, if I see a pop-up here, I'll add it If you're on a Mac, don't forget you might have to give permissions. You got it. Okay. All right. Oh nice I had an existing like controller for this that was based on teensy But um, so I made it like well I cobbled together an adapter here to break it out onto my breadboard and then I have two port expanders and then since that kb2040 has a Stem adapter I put the stem aboard on here and this is actually that that was my favorite thing about it because now I can just switch out whatever controller. I want right so here the macro pad had a That same connector, so I got it mostly some of the rows still don't work But I think it's a I think it's a hardware bug So I'm gonna make a better a better breakout. Oh, you're actually like shifting through all the key matrix manually Yep, you know Yeah, I ported the TMK firmware to tiny go so that's It's mostly there But yeah, but it doesn't have USB yet I'm still working on the matrix part of it and I'm gonna make a better controller, but And then my favorite part of it is this keyboard. This is the I don't know if you can see See it on the monitor there, but they have this It's like RJ 11 or something. Yeah, and there's four wires in there So I'm just gonna hook that up to the I squared C on the controller and then I can hang off whatever sensors I want Yeah, so That's cool. Yeah, I remember people used to have those dipping keyboards. There's not aren't as popular these days Split keyboards are much more popular. So this is kind of a callback to the 90s style and Yeah, so I'm The thing is I've really boxed myself into a corner because none of this will fit inside So I'm gonna have to finally learn how to make a PCB which And there's cat cat tutorials, I mean, I think it's a good excuse to learn how to do a circuit board a lot of people Learn their first circuit boards on a keyboard project So you're you're amongst friends Give me a shot. All right. Well, good luck. And when you do finish that PCB come on by and and shut off We'd like to see you update Thanks. All right. All right. Thanks so much. We're gonna go back to Jeff speaking of keyboards Yeah, let's see if we have that keyboard Yeah, do you want to put it on your overhead or do you want to hold it up? Yes, sure, I'll stick it down on the overhead because yeah, it's hard to see the button Yeah, it's this it's this round button. It just says help. Yeah says help and it's a jaunty at a jaunty angle Yeah, it's just ridiculous and it's not centered either. No, it's like random. It's above eight and nine sort of This is the new keyboard you get with your Twitter blue subscription. I know It looks like they had a provision for four more buttons More but they didn't yeah, that's it in that purchase you get other help buttons They they couldn't come up with anything that was as good as help. So it's like now Yeah, I guess staples that when they have the easy key they missed out They could have had an easy button on keyboards. They could release the keyboard. Yeah, they could have had their own keyboard So what a weird like what meeting did they have where they're like, you know what Bob? Let's go for it. Let's make a keyboard with one big But let's not have it lined up exactly. Let's just have it like 30 degrees Yeah, and now you can see the matrix just like the key A standard matrix keyboard inside, but they've got a weird scanning thing with two chips and I'd hope to just pop the ribbon cable off and bypass that but I can't get it out Can't get a compatible connector. So I have to go through this and which we're scanning in in a weird way So Person in chance that is that a trackball? No, that's just a round button. That's a Love we mentioned this before that's all it does and and I guess the other thing we don't know and maybe we could try to find like the Manual or something is like what happened when you press help button? I don't know someone show up Well when you get this working on your computer, maybe have it, you know Do you run a special command? I don't know what it would. Yeah Yeah, I mean F1 is kind of the help button now Well, you can have it pop up the party parrot gift. That's what that would be very helpful. Honestly, it could Yeah, or you just like play cat gifts. You'd be like look I can't take any more Beatles Can play any it could it could do a shuffle and play any song with called help or with the yeah help is a lyric Yeah, so this is the Atari xe system keyboard and there's my serial number if you want to verify it Help oh Boy Thanks for bringing this keyboard this keyboard is the funniest keyboard They're all good keyboards, you know, I think we're you know It's thanks for giving it a little bit of attention because I'm sure it was just always made fun of it the keyboard playground this big help button on its head I'm sure the other keyboards All right, well, thanks so much. Yeah, all right. Thank you child. Good night All right, that's our show until for the week this week Thank you so much everybody for making this the best half an hour of the week for us every single week next week Liz will be hosting We'll be back. We'll be hosting it We're gonna have Liz and then other folks help out. We did like we had six weeks Now we've got lots of folks that host the show and tell them we're so come by every single week Some 30 p.m. Eastern time show and share your projects Retro stuff and more and Yeah dust off that old keyboard and I would do something new. All right. We'll see everybody and ask engineer in a couple minutes
