 All right, Lady Eda What is this? Hey everybody and welcome to show and tell it's me Lady Eda with me Mr. Lady Eda Broadcasting live from the downtown Manhattan manufacturing studio also known as Eda fruit Where we do all our electronic manufacturing and testing and kidding and coding and videos Including this live show and tell so we're going to check in with some folks from the it for community And we're gonna get some people from around the world come by showing off the projects You're welcome to I get your webcam get your projects your 3d printing your soldering your crafting your crocheting Whatever is your building? We'd love to see it. We're here till 750. Let's Start off with Dan Dan what you got going on? Core developer for circuit Python. You're always working on the circuit Python stuff. What? What's a click in the clack in on your workbench? Yeah, we can hear you I'm gonna make something bigger all right All right, okay Yep, we can see your screen go Dan go Oh Dan you're now not talking You want me to go to Jeff and then come back to you Oh, no, yeah, okay. Yeah, you're back. Welcome back Dan. How you doing? Hey, all right now back. Okay, I've been working in keypad support for circuit Python 7 so that you can read different kinds of keys and buttons and because we're doing all kinds of keyboard stuff now And we want to read simple just push buttons like one pin per push button and sometimes you want to read key matrices like I've got a touch tonish keypad here that Wired to read rows and columns. It's wired up to do words and columns. That's the same thing. That's true on your regular on your regular keyboards So I've been working on that and I got a full request in and it works and you can try it if you'd like and I was going to demonstrate it Here. All right. Let's see Started here. Yeah quicko demo So I've got a circuit Python running on this metro M4 here and it's wired up to two different kinds of keys These two push buttons and this key matrix thing and I got a little demo program over here And if you want to look at the demo program, this is the whole demo program I have it. There's a new module called keypad. It's got key matrix support and regular old key support It's going to key shift registers to support to I say what pins the the things are connected to So let's go ahead and try running this program. I'll start pressing buttons here. Here we go So That's been one that's been two And it It makes events and if you do it really fast you can see sometimes it says Here it says there are two events queued Because I did it so fast that it's it's it's doing even faster than it's reading it or that I'm reading it But so that that will work for keyboards and stuff And also if I press the buttons Yeah This is the regular all that's key number one from this pair of buttons here And that's key number two or key number one and when you press it it stops stops the program I just wrote a little I like that you've written fdabs for quick a Python. Congratulations. Good work. All right Thank you. All right, so this is available. You can try it in the latest builds or it will be available It's in a PR PR. You can check out the PR builds. Yes, I'll put the PR in Discord, I'll link to our discord. Okay and good work. This is a big deal. All right, you know what time it is It's Roman times with with Jeff Yeah, so I like clocks and I have these mag tags So I wanted to do a mag tag project and it is the 11th hour right now actually as the Romans kept time so they divided the day from Sun up to Sun down into 12 hours 1 to 12 and We are 1112th through the way from Sun up to Sun down here where I am So what the program does is it connects to Adafruit IO to get the time Sends it to a bunch of nerly equations to find out where the Sun is in the sky does some arithmetic and says a 11th hour and There's a lot going on behind the scenes And you know you could just go find the equations that some JPL engineer probably Wrote but circuit Python can do the calculations. They aren't super precise for what I'm trying to do and Just a reminder, it's like the COVID clocks that people were doing it is the afternoon And at night it counts the watches 1 to 4 so it only updates 16 times per day I'm excited to see how long the battery is gonna last on the perfect mag tech project. Good work, Jeff Thank you. Thank you so much. All right now. We know who watches the watchmen. It's that clock. That's right Next Melissa Melissa. How you doing this week? What you got going on? I have a project I am working on for a YouTube video from my channel and is this MZ 8080 here, I can see lots of reflections here And right now have it on try and do it at an angle here. Yeah, and right now Let's say I'm gonna have it. It has a program in it here. I'm just gonna Start it and it's just blinking lights at the moment and You can actually change all sorts of settings and connect to it wirelessly and everything so there's a cool features on the back Here as like the whole circuit board set up and This right angle connectors actually for me to prove and it is just the right size All right, all you need to do now is port that to circuit pythons so you can program your MC 8080 yeah from within circuit Python that'd be cool All right, nice word Melissa post up your YouTube channel in the chat so people know what to look for I will do that All right. Nice. Nice Will be what you get going on this week. Hey there, you know the the inside that was that was Lightman's computer in Wargames That's right. Yeah, um Anyway, I almost didn't show up because I found out like trying to get pictures of TFT screens. It's almost as hard as LEDs and I hope there's some Solution to that like we found the LED acrylic. We need like screen acrylic or something. All right. That's a maker challenge Anyway, let's see if I get a picture. Yeah, okay, what's going on here over here. We have a Parallel capture camera of the type that are you know Cheap and popular now Raspberry Pi Pico we've I've shown this set up before and it's looking up at the camera. So that's what you're seeing on the screen over here But like a STEM a camera and it's like can we get these pictures across I square C to another microcontroller? And so yeah over here is a metro mini, which is just a little pokey, you know 8-bit AVR but yeah coming across I square C I'm getting frames out of the camera and You don't have memory to You know cash a whole image so it's it's sending the bytes, you know artisanally packaged Bites directly to the screen But it's it's starting to work. I'm actually getting images. Let's see if I get my fingers in there We should see fingers. Well, they were there, but like I say it's hard to hard to record these screens So progress happening I put your hand over so I can see your hand. Yeah, okay, so There's When you take the photo it freezes so you can see yeah, you can't really Okay Direction you can see it changes All right, well, this is cool. So you're never gonna get what you're running at 400 All right, well, we're gonna try to squeeze that up to 800 kilohertz maybe and we are okay You're like what and then we're also going to Try running this on boards with a larger I squared C buffer To see even faster, but this is pretty good. You're just getting an image over Yeah, the bottleneck is those little because you're limited to 32 bytes at a time on the ABR So I think bigger boards. I think this will this will actually run even better Okay, but look if it runs on this it can run anything. That's exactly yes, but There we go, it's happening. It's work Camera Stemma is is on its way. Yep. Okay, cool. All right. Thanks so much Oh and tonight we're gonna be showing a delightful speak and spell video on asking an engineer that Phil be due so check that out I'm excited. Yep All right, next up. Let's go to Liz. Hello, Liz. How are you? Hello? Good. Um, so I have the Neo-key for my one and when this came out, I thought it'd be really cool to do like an emoji shortcut thing So if I press this button Yeah, I'm gonna add your screen here. There you go. We got cat emoji and this button lightning bolt And then What is that? There's like a synthesizer emoji. Yeah, I use it a lot Because I I kind of almost prefer emojis to full words sometimes They're still good at expressing You know, I used to get Some feedback about having lowercase. I would type in lowercase most of the time And then I get some feedback about the you know text based emojis like colon and then you know open parentheses Then I got some feedback for emojis But I feel like emojis kind of just like now everyone would wish If you're if you don't like emojis Boy, lowercase doesn't seem like a big deal anymore So, uh, we use them for everything and I find that there's always a good emoji and when there isn't then you think about Which ones you want to see that like emoji commission come up with so Like if I was like, oh, Liz, do you like cats? You would just like you don't have to say anything. I could communicate fully with Liz with just emojis And we're like, wow, we look like cats. Yeah Cats and guitars and since this is like, yeah, you're rocking out and it's very efficient And you have light bulbs that you strike your enemies down with see And you tell good Yes, exactly. Yeah, all right. Good work right on good work. This is why we made that product Okay It's purpose. That's right All right, next up. Let's go to Michael. How's it going Michael? Welcome back. Hi Yeah, so a few months ago. I showed off this thing which is version one of my like satellite phone thing it uses Actually this same modem here the rock block Uh, which is pretty awesome But I want to make like a version two That is easier to build so then like I can make a tutorial and people can follow and learn how to do it So let me turn on that camera that could help Um, there we go the blackness of space. Yeah. Yes. Here we go Um, so I'll focus. Sorry about that. Um, anyway, so I spent the past few months designing a version two Um, the idea behind it is that everything would kind of like be around this core here um And I kind of wanted things to fit in almost like lego. So like this screen here You just plug it in with the stem IQT And then you plug that in there And things would just fit like lego like this fram ship would just like fit there Um, and then everything would be enclosed like this Um Yeah, I don't know why it's all focused. Sorry about that. I can see it that kind of it just fits together It's quite nice. And then like these like side panel things would be there too. And yeah, so that's that's that so far I just have to finish soldering things and like the communicator, you know, look going there. It's it's very cyber Yeah, and I'll use uh this uh the blackberry uh keyboard, but everything else is like eta fruit stuff. So Nice work. Not required, but we appreciate it and keep coming back. Um, as this project evolves and more It's been neat to see it. Thank you. All right. Thank you so much. All right except tim How are you guys so a long long time ago? I shared my nixie clock project and um, you know What's more fun than making more clocks with obsolete display technology? So these are a type of display I learned about from fran lab, which is an awesome channel. They're actually um Like they have a bunch of teeny tiny incandescent lamps in them and basically they all are loaded in the back here and um, there are basically films that project and lenses that project the uh the numbers onto um, like a uh, Sevi transparent screen in this case, uh Just some scotch tape. So the plan is to um, you know, build a clock out of some of these and um Have more clocks than I ever know what to do with which is uh, maybe not the worst problem to have That's what time is things that clocks measure. I love this display too. I mean, it's got a such an elegant look Like I really feel like I'm in a 1960s sci-fi movie talking to some computer at this time Yeah, and they only draw the bulbs only take about 15 milliamps So I'm just driving them directly with the uh with the arduino digital output and nothing's blown up So cool. Someone mentioned it looks kind of like an elevator too. Yeah, it does. Yeah I like it. It's got it. It's got a certain warmth to it. It's like it's a vinyl You know, it's interesting. We're at the stage of electronics where some things seem calm and some things don't This seems like a calm Light to me. Nothing stressful with this display. It's like countdown to something Sure, bring me my injection. It's all good now. Okay. All right. Okay, great Thanks Thank you, selenia. All right next up Alvaro, how you doing? Hey, hey, welcome back. I'm meeting Mike and trust what you're up to So I have a couple of things. This is my diverse card and that is important because I'm going to this place in october I'll be there Complete month Wow going to be is that goku, which is a place with that only researchers get invited to So that's pretty pretty exclusive from okay. You're gonna go and see that giant fish Under water, okay Yeah, yeah, I'm actually going to teach the the park rangers how to how to code and how to do I'm actually thinking my my my fun house over there. So they're actually going to learn on this one All right. Well, thanks for teaching folks around the world programming. This is good. Yeah So I also this week I got this thing. Uh, this is one of the first, uh, chinese RISC five words. I had I actually haven't So this is It's called the nisa It only has one chord in like two gigs of ram or whatever I haven't again. I haven't even taken it out of the box. So this isn't going to do this week. So thank you Yeah, um, what board did so for the riss five boards we have one from I want to say sippy or something like that and then we have one from beagle high five makes one Beagle bone There's a beagle bone c3 Of course risk five. There's one of the esp 32 s c3 And also the actually the s2 like the chasm has a micro risk five core So people are starting to do with yeah, one of the things that I think folks are waiting for is for us to Make sure blink it works on all this. So if you want to if you want to work on that, let us know too Um, because we're going to be spinning up. Yeah, we actually don't own any of the list the linux Loose five was like we tried to get one and they were none available Yeah, these are actually kind of cheap like a hundred dollars. So these these are gettable As soon as I turn it on I'll get the blinker working on it Yeah, I have like half of it working already on the beagle. So I'll show okay, cool drop me no pt atata fruit com when you get stuff going and Our team is starting to do some of that too But the boards just came out But I think that'll allow people to use them because the boards are out But there's not enough projects yet because they just came out And you have to like all this code should work with something Correct right on. Okay. Well, I'm a I'm a riz five member since this week. So Congratulations. So all right. So you have your work cut out for you. You're set up. All right. Well, if you can While you're Traveling to stop by the show. Let's know how you're doing. Yeah Well, they actually don't have internet over there. So no internet. All right. Well, take some photos That's why I took my ass. You can code with that internet. Take some photos and show it to us when you get back All right. Thank you so much All right. Thanks everybody. That is our show until this week I have to add a couple things to the ask an engineer show. So this is really good timing Come on, sir. Like we're gonna get ready. Yeah, this is stretch and we'll be back here in 10 minutes for asking All right. We'll see everybody next week. Thanks for making this the best half an hour ish of our week every single week This is show until the longest running show until Live on the internet for like a decade now. Yes. Thank you so much for making this Uh a uh fun night to look forward to every single week. Okay. Bye everybody. Bye everybody
