 And welcome to Lady Aida. Hey everybody, it's me Lady Aida. With me is Mr. Lady Aida. It's time for the desk of Lady Aida. This is my desk. That's right. I'm a mess. But it's okay, I got some electronics. Yeah. We're not loving it. Summer in the city, doing electronics. We went outside. It was great. I got a little sunburn. Yeah. But we had a great bunch. We saw people in person. It was amazing. Yes. Okay, but I did. Yesterday I did a bunch of electronics before we went out. So I thought I would show off some of the projects. I did. First up, I got my RP nano connector box. That's going to be overhead and I'll show this off. So I got... Arduino is also using the Raspberry Pi RP2040 chip. We got one. Yes. And we're going to make sure it runs circuit python. Right. So this is... I have to remember how to use this thing. Okay. So yeah. So this is the RP2040 connector. This is interesting because Arduino is kind of traditionally known as... Sorry. There you go. It's traditionally known for using, you know, SAMD core series, AVR series, you know, very... I mean, they have a couple STM chips here and there. But for the most part, they're very, like, microchip focused. And so it's kind of cool to see them joining forces with Raspberry Pi. Using the new RP2040 chip, which we think is a sweet ass chip, on this board, the 2040 Connect. And so I ordered one as soon as they were available and they showed up yesterday. And the neat thing about the RP2040 is built-in Ramboot loader and we've got great support for it in circuit python. This board also has a Wi-Fi chip. And this is a Nina... Why isn't this locking? Okay. Hopefully it should lock in. So this is the U-Blocks Nina 102, which is an ESP32. It's like the tiniest ESP32 modules. It's adorable with the built-in flash. It's got this 3D antenna, which we actually talked about 3D antennas, I think, on a desk lady a couple months ago. It's got the RP2040 here. I mean, it's got, like, a 201 component. It was small. These little microscopic parts. It's got a PDM microphone here. You can barely see it. It's a little gold spot here with the PDM mic. Reset button. I think it's an RGB LED, one yellow LED, a green power LED, power circuitry. This is flash memory. So it's got, I think, 16 megabytes of flash and the RP2040 chip. And then it has also a gyro on it, by the way. And so Liz, BlitzCity, got hers like a day earlier. And so she put in a PR to add support for the circuit Python. I collaborated with her. I just, like, fixed a couple of typos for the CI to be happy. And I tested it out and it works. And so I did a couple of demos. If you check the PR in circuit Python where I merged in support for this, I have two demos, one that prints out the gyro data, because we have a driver for the built-in gyro and it just works. I also wrote a Wi-Fi demo, which is neat, because the driver we have for the ESP32 airlift, it's the same form. We use the same form as Arduino. So it would make sense that it would just work. So I did a demo. Right. And so let me just, before you show the demo, let me just tell everyone. Adafruit is not saying to go out and buy cryptocurrency. When we do these demos, we need to find an API that anyone could just cut and paste a URL. It needs to be HTTP, so it's not HTTPS. It needs to be accessible. It needs to be available. It needs to have something that when you look at the price or the data you get back, like a stock price, for instance, or in this case, cryptocurrency, you could say, oh, wow, that's crazy. I remember what was that place. And the JSON data has to be small. And it has to be a small thing. Yeah. So the problem is... If you have another API that does not require a key, does not require SSL, changes constantly so you can make sure it's working. So we do demos with new stock and weather. And small JSON output? Yeah. So over the last 10 plus years and then in former lives, including me, the demos that I would do were new stock weather. Now, when there's something like a stock ticker, it's not endorsing the company. You're just showing you can get data in with this stock ticker. So here's the thing. We're not saying buy dogecoin. It's a joke. Please don't melt down. I personally don't even think it's a good idea. Don't do it. Please don't melt down and blame Adafruit and or a little more personally for global warming because we're showing this demo. It's just a demo. That's my disclaimer. Okay. Show the demo. Great. So this demo, I'm demonstrating iSquared C display IO. Because I wanted to test a whole bunch of stuff. It's using iSquared C connected to the OLED display IO to do the font thing. Because it's using this custom comic sans font. Time to the internet, getting the data and then displaying it all in CircuitPython. So this is a really, it's a really good all in one demo because I wanted to, you know, test SPI, iSquared C display IO, font handling file system, like all the little things are tested. And looks like hopefully, you know, if you did own it, you sold it before you lost like all your money because it went down from even earlier when I ran it. So this works. So what's neat is if you have an RP2040 connect, you can definitely go on it in Arduino and Arduino has Arduino core support for this. If you want to run Python on it, I know for a fact that you can use it with the Wi-Fi and the sensors built in. If you want to use it with MicroPython, I'm actually not sure. Well, first of display IO, the display stuff won't work because that's a core CircuitPython thing. The ESP32 SPI stuff might work, but I'll be honest, we haven't tested it with Blinka. So it's a little iffy. If somebody wants to try that out though, try following Melissa's guide that she just wrote on how to install Blinka onto MicroPython boards, like we'll load MicroPython into this, load Blinka onto it and then try running our example code. It might work, but I don't know. But it doesn't work in CircuitPython. And I'm so psyched. This is so cool because I have no plans to make one a board like this. That's all in one RP2040 sensors and Wi-Fi. All right, we know that it, go buy their board. It's awesome. It's very, very, very small. It's a good price. So I personally like having ESP32 as a Wi-Fi coprocessor. I know some people are like, why not just use it? But I think the native USB is worthwhile. I mean, like, you know, instead of a USB serial converter for the same price, you get my controller. Great. So that's that. So I got that working. One thing I will say to note, there's no boot zero button, like the button that lets you get into the boot loader. So you have to wire it up. It's not too hard. There's just like a jumper here. You can even use a little piece of wire to jump it while you plug it in to get into the boot loader the first time. Okay. So next up, any questions about that? No, I appreciate our community who's like, they're all cool with this. They're not blaming you personally for like the deaths of owls and seals. And oil spills. Personally, I don't really get crypto. I don't get it, but whatever. That being said, if someone knows of a demo that shows how easy this could all be in a very quick way, we're always looking for ones. We do weather. We do currencies. We do news. But whether we can't get to without API key. It has to be an API that requires no key. Yeah. Even a free one, because the whole goal is that people have to be able to test it without having to go and like register for an account and get your like, now your data is being collected. Yeah. So I don't understand why, but cryptocurrency price APIs, for some reason, the ones that I've seen do not require an API. Yeah. One thing that we do show as well as we do our quotes demo, we have quotes off of our website. I do do the quotes demo a lot. Yeah. So we've got quite a bit. The request that we get is, oh, can it do like real-time updated data? So we're like, oh, yeah, sure. There's this silly dogecoin thing here. But it's not a number. I like that when it's a number that is changing worse. The quote, you have to get a different one. I don't know. I mean, yes. I do both demos. Yeah. So we do that. Okay. So next up. What was the name of the, can you hold the box up? What was the name of the Arduino product? It was the... Is the Arduino Nano RP2040 connect with others? Yes. Oh, also, I think our quotes required SSL. That's why I don't use it. That's right. And I want something without SSL because SSL causes other problems. Okay. So this is a revision I've done for the Stemma friends. So this was a little like debug pal because I'm constantly getting iSquared C devices and I'm like, what iSquared C address is it? And is it working? And do I have to write pinouts? So I designed this like a year ago now and it was with a Samdi 21. And it's got like Stemma QT ports and USB-C and a little battery port and a little button here and a larger port that you usually grow. And this worked. It worked just fine. But the problem is the Samdi 21 just didn't have a lot of RAM in it. And so definitely this would not have been able to run circuit Python, which was kind of like a bummer. But I wanted to keep the price low. And I also need to be fast, a fast enough chip to do iSquared C sniffing. Because one of the things I want to do is not just address scanning, but like actual data sniffing. And so I kind of was like, I kind of hemmed in the hot on this and I was like, kind of like working on it. And I was like, well, I could do with the Samdi 51, but then the chip is really big because they don't make small Samdi 51 chips. Like this is a Samdi 21e, I think. Yeah. So this is like the little mini, I think it's a four by four chip, maybe five by five. So I put this aside. The hardware was working, but I was kind of like, I'm going to wait on this. But then with the RP2040, I was like, ooh, I can remake this now. And I can remake it with this new fancier chip. Now the chip is a little bit bigger, but it was still kind of worth it. I just made the board just a little bit taller to account for the chip and the flash memory and it made me fit another button in. So there's a user button and a reset button. Yeah, I made them both the right angle. The improvement of having it be an RP2040 is now it has a ton of RAM, which is awesome because I can do stuff like frame buffering, which I'll show you. It's also fast as hell. It's 130 megahertz. So compared to the Samdi 21, which is like 48 megahertz, the GPIO is fast enough. I can do very quick reads. So again, I can sniff. I want to be able to sniff basically 400 kilohertz I squared C and have the data output so you can do logic analyzer type things. And so I'm using the Philhauer Arduino Core. And so this is just a demo of it with the I squared C scanner. And you can kind of see barely it says 44. So this keeps touching pins. But when the pins aren't touching for this sensor here, it's scanning and it's showing that this is a SHT30, I think is the sensor inside of it. So this is just me doing an I squared C scan test. And if I disconnect this using these cables, it goes away. So it is an I squared C scanner. And then I can plug sensors in over I squared C and detect it. I also have I was doing some stuff over the weekend. So what I did, so put this into bootloader mode. So when I started, and this is not a thing on the core, this is just a common thing, the I squared, the SPI core was not really optimized. So if you want to draw to it, this is just drawing like red, red, green, blue, you can see you can actually kind of see it drawing. But it's not crazy fast. Even though this is running at 32 megahertz, because it's sending like one byte and then it's just waiting and then it returns and it goes another. And it works perfectly well, but it does one by that time. What you really want to do when you're displaying to a screen, especially when you want to write a whole frame buffer is you want to give it a buffer and say, write all this data at once, like one byte after the other with no delays in between. Sometimes you have to use DMA for that. In this case, the Pico SDK has support for sending a buffer but the Arduino coordinates. So I'm working on a poor quest to do that. So when I do that, so you can memorize, it's like, okay, it's like, you know, but two hertz, it takes about half a second to redraw. If I load up my fast SPI demo, you'll now see it's actually so fast that it's kind of freaking, like you can't, it's starting to tear before this. It displays the image. So it's drawing now at about 30 frames a second, I think is the speed so much, much faster. Like it's actually looking kind of, it's kind of freaking out a little bit. But in person, you can see it goes red, green, blue so fast that it's being, the display's tearing. The display's updating slower than the data's being pushed to it. Which is good. You're sending data fast enough. So what that means is that I can do frame buffer projects, which is, what I mean is the display, instead of drawing to the display, which is very time consuming, I draw to a gigantic chunk of memory and the RP2040 has 260 something K of RAM so I can buffer the entire display, do bytes times 240 times 240 in and then blid it all at once and I can like do stuff with IRQs where the blidding maybe happens in the background. Let me see, so my demo's running here. And that'll let me have really smooth motion of graphics so I can do things like plotting and I won't get like weird flickery effects, which I don't know, why have those if you don't need them. So this demo is actually a UR scanner. So what it does is it can read UR data but it actually auto-bods. So when I connect it up, it will use the GPIO to read pulses coming out of this GPS, for example, and it will measure the pulse widths for like a couple milliseconds and it'll calculate like, okay, what is the BOD rate it's sending at. So let me do this. So in this case, I just don't think it's gonna go in but you can kind of barely see it. So this is automatically detecting 9600 BOD and it's displaying the NMEA data which is coming out of here. It's really tiny text but I think we're just debugging like just what BOD rate is it, what data is coming out of it. It's even running. I think it could be really handy. I also got the same thing going with a Raspberry Pi. So as you know, because I wanted to test will it work with 115 kilobod. So this, I do have to reset it. So let me reset this because it's like, it needs to redo the auto-bod detection and then plug in the USB here. Let me see if it works. Yeah, so you can see, it's printing out like system D and starting device. It's very tiny but you'll have to just believe me that you can see the start-up messages from the Raspberry Pi show up on this little console screen. So yeah, not as good as like a computer console but better than nothing. So those are the two things that I worked on this weekend. Oh, also Mr. LaData really wanted me to, oh, Nuts is like login, where has been. So you know, like if you want to just like, what's the IP address? Is it booting? Yeah. This can be handy. This is very small, it's hard to read. But I wanted to make this a small little helper. So I got some tubes because Mr. LaData wanted me to do a VFD Trinkie. So we're doing a limited run of some Trinkies of parts that we know we're not going to get a lot of and we're also not going to make a lot of. So we're calling them again. This is a joke. NFTs, not forever Trinkies. Yes. It's not digital. We're not selling digital anything. You should not buy digital artwork on a blockchain, guys. Well maybe, I don't know. I don't have an opinion about that right now. I do. But what I'm saying is we're calling these NFTs not forever Trinkies. So we're going to have a little like mini ice tube looking thing. Yeah. We're calling them NFTs. They're not actually NFTs. You do not use crypto currency. There's no burning of the icebergs for this. We're only going to make like 10 of these because I can't get these to only have like 10 of these tubes. So anyway, these are, these are VFT tubes and they get 20 volts. So we'll have to like make a little boost converter. Let's go to some questions. Ask your questions. Is the speed up approach just for video or can it speed up any I squared C protocol with lots of data? Perhaps. It can do both. I mean the RP 24 is just a massively more powerful chip than the CMD 21. And so I'm glad I waited. It's a little bit like, okay, so it took me like a year to wait for this chip. But it's the it's the it's the much better chip and also there's much more storage. It could do things like auto detect what sensors connected. So I want it to be like a little like debugger helper. Like it's something I personally want because I'm constantly like, what's the I squared C address of this? What's the UART data coming out of this? Like I want to sniff UART data and like doing that is so annoying bi-directional I squared C data is so annoying to sniff. So this would be like a little helper. And you know, I like the sale is but the sale is they're just they're out of some people's budget and I respect that. It's like I'm not going to tell people go by knockoffs. I'm going to say like I'm going to design something just for I squared C debugging because there's so many people who are like, I just want to sniff I squared C and verify what why like so many platforms I'm working with now have like repeated start or they don't do repeated start or they always do repeated start or they don't nap the same way or there's like a delay I actually need something to help analyze I squared C and something I can give people the feel to do as well. So having that code will be helpful for this demo friend. Yeah, we were doing a CMD one and now we're doing a Yeah, the original was this. It was a CMD 21 but it was a 21 circuit python. It just couldn't do it. So I was you know, this is known. It looks very similar. Right. Which is better. And a couple of folks are going to mortgage your houses to buy NFTs from us. Okay, if it's like a little like ballhouse maybe. The reality is are not forever trinkets are probably going to always retain their value. It's an excellent investment. Yeah. All right. Collect them all. Okay, I think that's it. Oh, and there's one more thing. CMD 21 based circuit pirate. You can see that. Oh, was the serial monitor in Arduino or circuit python? This is in Arduino. Oh, because here's another thing. So the the scrolling text, by the way, so I forgot to actually talk about the thing. So having the text scroll so smoothly, it doesn't look like super smooth, but it's quite smooth. You have to do that with a frame buffer. Like there's no way to erase the TFT memory. Erase it. And you're probably like, well, Lady, don't you know that you can scroll the TFT display? Like it has internal scrolling capability. Yeah, but I wanted to have like a header at the top that had information about the bond rate. And I probably have a footer as well. So it's like once once you're doing that, it's like to spend the extra 10 minutes and the Ram is free. The Ram comes free with the chip. If I have the Ram, use the Ram buffer, the whole display, bleeding it, the plotter. I wrote this plotter code a while ago for the clue, which will run well on this as well. You can't scroll it because the plotter is is a sub image with a with a not gradient, like dots in the background, like the gridded background called like a gradier or something. I don't know the name of it, but you can't use the built-in TFT scroll. And believe me, I was like, I can use the TFT scroll. And I looked at it and I was like, oh, no, I actually can't use it built-in TFT scroll. I have to do it in a frame buffer. Okay, you're going to share those PCBs. Also, someone's tossing the idea prototrinky. Prototrinky. Yeah. Yes, this is circuit pirates. This is actually really old. This is now like, I think this is like a three-year, something-year-old project. So I really liked the the bus pirate, but I wanted one that was programmable on circuit Python. And the same software it would be, it would just be something that you could use in a similar way, but you would script it in Python. Because one of the things that I've always really wanted, well, now I have a solution to it on my own, but standalone chip programmers are just, like, they're either like $3,000 or you build your own. Like there's nothing in between. And I thought this would be neat if we can make, you know, a little debug tool that could also be a standalone tool. So similar to this, but have more GPIOs and have like switchable power and like, all, you know, I think this is like all level shifted and everything. So this is a SanD21 and it actually got, another thing is you need to have this separate UART terminal if you wanted to like code it. I actually got pretty far and then ran out of RAM and with the SanD21 like three or four years ago. And I was like, oh, I should probably do this with SanD51 and they put it aside. But again, I think in the RP2040 would be an excellent choice for this chip and a ton of RAM, especially if you're doing data captures. Like if you want to do a logic analyzer, you want to be able to like capture a ton of stuff and then, you know, on a trigger and then send that back up to the computer for analysis. And the RP2040 has enough RAM to do a, you know, not a huge, but a significant chunk, 10 times as much as the SanD21. So, Circuit Pirate might actually come to life. Very old PCB. All right. We're going to date code on this. There's not a date code. It's old. Is it great search time? It's time for the great search. All right. Where are you? Okay. The great search brought to you by Digikey. Thanks, Digikey. Every single week, Lady Aida uses her powers of engineering and smarts to go to the Digikey site and find all the things you need. This is especially helpful for part shortages when you have to do things like substitutions and more. But this week, we were on a mission because we're making a bunch of keys. Well, people were asking, so I got a quest of like, so, my team was like, I've seen these really gorgeous keyboard cables. Yeah. Which, again, I'm not endorsing or not endorsing spending $100 on a keyboard cable. I was just personally curious what is up with these. And they're like, oh, they use these cool aviation connectors. And I was like, well, what is an aviation connector? And so I did a little bit of research and they often use limo connectors or sometimes like the YC8s or something. There's a couple of variations. But limo or, I remember limo connectors, we use them in the media lab for our wearable computer stuff. We would have the twiddler on a limo connector in there and for, so if you get caught on something, you could easily detach it. And so I thought I would first show off these cables, but also, look, there's people who, you know, if you're doing projects and you do really, really good push pull connector, like nothing really beats a limo. They're amazing. They are not inexpensive, but they're very high quality. There's a reason they are often used, as you may guess, for aviation. I do understand why folks will spend time and effort and energy to make a beautiful keyboard because you might be using this thing eight to ten hours a day. Like what other thing touches you eight to ten hours a day, maybe your phone? Pillows. I have a really nice pillow, by the way. Like I got a really nice pillow, like kind of somewhere in the middle of the pandemic, and it was, it really helped. Yeah. It's not from the MyPillow guy before, before someone gets honest about it. Anyway, so I can understand why folks like these, because it sits on your desk, it's probably in your living room or in, you know, the most intimate place in your home. There's this keyboard. So I understand why people do this. And I think one of the things... Yeah, this is a really beautiful one. I was just Googling, I was like, oh my God, this is gorgeous. I think one of the things outside of the community is fine. But I think one of the things outside of the community is like, I think there's a tendency to like make fun of folks and say like, oh, you're spending all this money on this. So what? Like it's this thing that you use all day long. Like if it's something that brings you joy and you built it yourself, like that's fine. It's cool. Is that cool? Yeah. Anyways. So we wanted to find out more about these. I'm curious about them. So, so, but you can, you can get them pre-made and I will say that's a good idea to do it. This is just more like if you're personally should be using it for other stuff. It's, it's a similar connector to this. So if you look online, so this is, this is one that actually uses a proper limo connector and you'll, you'll know them because they have these little red dots and these grooved connectors. So you see that the, the cable is coiled and then you can, you can quick connector. You can change out the contacts. So these are usually four pin cables because they're using USB. So let's go to Digikey and so let's look for, you could actually just search for limo. Although I'll show you how to find the whole category. There's actually a lot. They're, they're often, they're actually called circular connectors and you can look. So the only thing is that there's like a ton of stuff that limo makes. If they make, even though they're called limo, it's, it's, it's a little bit like the Kleenex thing, limo is the name of the company that makes them, not the name of the connector itself. Even though the moments that we said limo, you know, free watch, I was like, oh, I know exactly what you're talking about because they're really nice. It's actually something more like this, right? Like that's what it looks like. Yeah. You can go to limo.com slushy and someone dropped that in the show. Dude, you can, yeah, they're, they're called medical connectors which is like, they're, I mean, these are like, these are amazing. These are like, they're so enjoyable to use. Okay. So that's, let's look for active and let's look for we don't want, we want free hanging. And we don't want panel mount. We want them, the ones that panel mount would mean that one side is a panel mounted and the other side pulls out, which is, which is fine. But we don't want that. We actually want free hanging, which means that they're in between two cables. So they are literally free hanging. They're kind of the most stressful thing a cable can do, right? Because it can get caught. It can get yanked. It can get twisted. There's, now there's two sides that are, that are very delicate. So that's why these cables, these cable connectors are cool. Someone made custom cables for their brother for their birthday. Oh, look at that. And so that's cool. Those are cool. I wonder how you coil the cables. Okay. Yeah. So this is, these are the nine cables. Next up, you know, they're still like 14,000. I mean, there's tons of these. I know that we kind of want these, right? So let, but let's show how to pare it down to get to them. So the next thing is, is how many positions we want. Now, there's a lot of options. 114. I gotta see what, what's 114 connectors? What, what is this unholy? Oh my God. This is, look at this. This is awesome. Okay. I don't know what, what you would need this for. Um, but if you did, I guess they, did you keys got it? You can, you can use them, but we're not going to go 413. We're going to go for four and we're not going to do three plus one coax. We're going to do, I don't know what quad racks is, but let's just do these four to make the custom cables. You coil it with the post and then heat gun and a lot of patients. That makes sense. A lot of patients. Yeah. I'm going to try to make one of those. I think we should. We've got these, we've got these nice woven cables. I wonder what happened. Okay. So next up, um, let's, you know, you can get different colors, but you can start looking at these, these are like, basically when people talk about the email, they have different series numbers and the series numbers is how large the cable opening is. So actually let's, why don't we make one that'll fit this cable I have here. I didn't plan that, but you just, uh, grab my, my multimeter, my, uh, it's a toy calipers. So, um, I'm going to measure the diameter of this woven cable that I have. Maybe this, maybe this cable is a little, a limo if I, so you measure the diameter and it's three, you know, 3.7 millimeters, 4.14 inches. So this is done in, yeah, it's kind of like an inch. And there's always like a little bit of a range. So, you have a 0.14. So let's look at the cable openings. So you can do this one, this one, this one. There's a couple of, uh, let's see, 1.4. Okay. So these are the, the 0.14. I'm going to do this 1.4.6. That's the, that's the max. Yeah. And I want it, you know, you want it to not be, you can't, you don't want, you definitely don't want something larger because it'll, it'll be floppy inside. Okay. So let's apply. So now we've got only a hundred, three hundred. This looks easy for lightsabers too. Yeah. Okay, cool. Okay. Um, I don't care too much about the shell finish, although if you care, you know, you can't see what is in stock, but definitely threaded is what you think you've threaded on. Um, whereas push pull, which is what a lot of people like, you, there's actually a little like sleeve on a spring and you pull it to detach it. And then you can snap it back on. Again, very luxurious. So let's do push pull. I don't really reduce the number any. Um, and then next up, let's, let's just see what's Because that's actually going to cut it down a lot. All right. So basically, we've cut it down. And we can look to see like this is, yeah. These are glorious. Let me see if they have a version that has a 3D model. But this one shows you all the cons. So when you get these, it's a kit. OK. And this is one side. You need two sides. Don't forget. Both sides are required. I guess there's a request for a stemma. Yeah. For is perfect. We can make stomach QT to limo to make it waterproof. OK. Yes, you could. So you can see that this is the plastic bushing that holds the four contacts. There's a shell. This is the spring load part. This is the back part. This is the, you can see that there's a little bit of a groove. This is what grips the cable. So this is what you get for the cable grips. So in general, there's different families. So what I did research is there's different family series from 00B, which is the smallest family, literally the thinnest, to 0B, 0E, and up. I'll say most people use 0B. That's kind of the most common. But 00B is also available. They're just literally much thinner. Like these are very thin. They might be a little tougher to put together. So it's up to you. Can you go back to the keyboard picture on your browser? This is actually not a limo, though. I just wanted to show this is where they end. This is what it looks like where it kind of ends up. Yeah, this is what, so this is actually a really good image, although it's a little bit dark. By the way, View Image was removed from my browser, and I'm going to go and put some developer for removing View Image. Like I have to install a plugin to use View Image. And I'm really upset about it. Depending on the browser I use, I have all these plugins to get functionality I used to have back. That's weird. It's like little patches that come. So anyways, so this is what it looks like. So this is what it looks like. So you need both sides, don't forget. Yeah, that's cool looking. It is just really cool looking. Yeah, these are just like, they're so cool looking. But I just wanted, because I know people always get like, oh, this is an audio file. It's just because it's cool looking, which actually really respect. They're not like, oh, this makes you type faster. They're just like, it's just really cool looking, which it is. So yeah, but also the demo connectors are really great. Anytime you're doing, like if you're doing a project that needs quick connects that are really durable and desk proof. And I don't think these are waterproof. They do make versions that are, but really connectors are the things that take down. I've not seen anything destroy a project faster than bad connectors. So good connectors are good. So this is kind of the one that most people are using. The zero B series, FGG. Chances are if you see somebody making a keyboard with a limo connector, they're going to be using this. Okay, how much are they each? They're 22 bucks. Yeah, sounds about right. But here's the other thing, and let me just say this. But they're really nice. If you're making your own keyboard and this is a piece of art and you're going to have it for years, that's pretty cheap considering how long you may have it. And like you bring- It is a very- Yeah, anyways. And then don't forget, you need the other side. So sometimes they have the mating connector on the back here. At the bottom here, they show you the mating side. So there's panel mount mate and other. So you'll also need one of these, just FYI. She'll need both. They're really amazing, though I will say. So there you go. This is limo connectors. Great for keyboards, but also great for other projects, including, I guess, medical and aero, nautical engineering. Yeah. That's the great search. All right. Limo. Where? All right, some questions. Yes. Do they need an additional special assembly crimping tool? No, they don't. That's a very good question. Thank you for asking. They are solder cup. I should have mentioned that, but they are solder cup, which means you do not need to crimp anything. You just have to be very careful assembling it. I will say it's not a bad idea to use heat shrink. Heat shrink over the solder cups. Why not? But you don't technically need it. All right. Bill is a bad guy, Bill. Bad connectors that have killed a lot of magic wheelchair projects is true, especially if you're doing, yes, if you're doing some building projects, wheelchair stuff, these connectors are really good. Someone asks, I have lots of those VSD tubes and would love to buy a board to drive them, any options, opinions, suggestions? I'm gonna say Chick-Tindi. Chick-Tindi and Etsy, because I did see a lot of people doing, doing a lot of VFD type projects. eBay too. I got these on eBay, to be honest. I've got a 10 pack of these. These are Russian tubes. Yeah. Okay, cool. Any other? I'm just gonna let folks know about something that's coming up. I got the okay from Siemens. They're gonna let me interview them. Yes, it's true. They bought Supply Frame and part of that purchase was Tindi. Tindi and Hackaday. Hackaday. And so disclosure, I started Hackaday a million years ago. I'm not gonna do it now. I'm pleased that it's still around. I'm curious what they're gonna do with Hackaday. So I'm going to interview them and find out. So that's that. Okay, during the week we have all of our shows. That's right. Tuesday is product pick with JP. Yes. On Wednesday, show and tell. We're back. And Mask and Engineer fully backed. Yes. Fully vaxed. Fully unmasked now. Yeah. Waxed and unmaxed. Yeah. And then on Thursday, JP's workshop, also one day before that, sorry, 3D Hangouts with Noam Pedro on Wednesday. Yes. And then Friday, Deep Dive with Scott. So we have a full week of shows. We have a ton of stuff coming up. Conflab every day-ish. And 30 right when you need it. And that is our show for tonight. You're in bubble two. I want to say thank you to everyone in our community who's super chill and they're supportive of each other, regardless of the project you're working on. Everyone makes something and there's lots of things that we can do to help each other and I'm glad that we found each other in this community. And it's been a long year and things are coming back for the first time and over a year we had lunch with someone. It was amazing. It was weird. We hugged them. Yeah, it was super weird. And it was okay. And so- We were permitted to. Yeah, and the restaurant, you had to show your vaccination card. Yes, and they thought ours were cool. Yeah, and it was not a big deal at all. It was actually just like, oh yeah, hey, how's it going? Oh, here's the thing. And you know, it was cool. Yeah, you were masking the restaurant until you get to the outside table. We sat outside and it was cool. If folks are around the world and you're like, what is normalcy? What is going to happen? You know, you can get used to anything really fast. And I'm getting used to this again. And I'm thankful that we're able to see people. If you have access to vaccinations, please, please get it. Yeah. It's great. You're just tired for one day, but then- I just got stronger. But you got stronger. I had a weight lifted off of me, so I don't get stronger. I just had less stress about it. All right, so that's our show. We'll talk to everybody. Thanks for coming by. That was this week's Disc of Lady Aida. Thanks, everybody. Bye-bye.
