 Here we go. No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no. All right. I just have some breaking news. The wireless LEDs work with some toothbrush stands. Good. That's important. Okay. Anyways, what's up first? Okay. First up, we've got a Perf board, and this is a weird Perf board. This is by request. This is a 2-millimeter pitch Perf board. It is not .1-inch pitch. It will not work with microcontrollers or dipchips unless you happen to have Cold War Russian 2-millimeter pitch dips, which is, if you do, that's really cool. They're very rare, but this is useful for modules like XBs and, like, once in a while, there's other Wi-Fi modules or dev boards that use 2-millimeter pitch, and you're like, I want to prototype with them. This dev board will do it. If you need .1-inch pitch, do not buy this. We have ones in .1-inch pitch, but these are, again, 2-millimeter pitch. Okay. Next up. Okay. Next up, we've got from Pimoroni a Pico LiPo charger add-on for the Raspberry Pi Pico, which adds a LiPo battery and charging circuits. You can charge through the micro USB on the Pico once this is soldered on. There's a cute off switch. I thought I had a little demo I thought I would show. Yeah. Okay. Show demo. Okay. So this is the Pico shim. So again, it goes on the back of the board. That's clever. And in this case, we soldered it through, but you can also solder it, like, directly on. And then just one second, let me grab my micro USB, which fell on the ground. Just not correct. Yeah. Gravity is still working here. I know. It's a new one's wondering. You charge it. It turns red, and then that turns off. And then there's this cute push button switch with like an SR latch, and you push it to turn on the circuit. And when you see the white LED, it's on. So it's just an adorable little way to, you know, you can still plug this into whatever, you know, or maybe you want a little extension cable, a little extension headers. But you can also, you can turn on and off, charge the battery. Great. I think this will work especially good with the Pico W, so you can make wireless projects. Rainbow Allens. Rainbow Allens. Yeah. You were asking about these. You really liked these rainbow, which, Ironic, is apparently Adam Savage also highlighted a similar set. Great minds think alike. Just coincidence. We ordered these many months ago. It's really good validation. It's when you know someone, and you see that they're going to listen to a band or a concert that you like to, and you're like, that's cool. So we were testing these, and then we wanted to make sure they would work out great, and we do a lot of stuff before we put it in the store. Yes. And then... These are actually really nice allen rings. Yeah, these are great. You should get these. And the rainbowy. They're beautiful. They come with a little, like, handle if you want to get a little bit more torque on them. They're metric, but honestly, we kind of use these for everything, and they work wonderfully. They've got a shiny chrome finish. Yeah. Who doesn't love that? And of course, they are super rainbowy. Yep. Next up. Okay. Next up. Okay, this is an interesting, weird thing. So I actually got this from my laptop. And then, because, you know, I have a Mac laptop that you gave me. Yeah. And it's one of the modern M1 ones, and so it has a USB-C port. It doesn't have a Mac jack. And if people know me, I'm clumsy. Things fall, things break, you know whatever. That's why I learned to be an engineer, to fix all the stuff I broke. So what's neat about this is, I'll show this also on the overhead. It's a USB-C right angle adapter that's also like a Mac jack. A MagSafe adapter type thingy. Yeah. The end comes off. So this, you plug this into your device, and then it magnetically flies on. And of course, this USB-C. Also good for little dev boards and stuff like that. You can do a lot of things. Anything with USB-C, speaking of. So, for example, and what I like is it also has a little indicator to let you know it's charging. If you wanted to, you know, of course, you don't have to use it with, I use it with a laptop, but of course you can use it with your dev board and then you can easily connect it, disconnect it to turn on and off your electronics so you can see it. Turn it on and then bam, disconnect it. So this is, all this does is turn a USB into a right angle with a little magnetic jack. It doesn't have any smarts in it. It has an LED and it can do 120 watts. So it works well for laptops, which is what I got it for. But you can use it with dev boards as well. Okay, next up. Okay, speaking of power, this is also by request. We have a panel mount 2.1 millimeter, 5.5 millimeter. Jack, it uses the panel mount system that I really like. It's just a round one inch hole. It means it's very easy to drill or cut into any material because it's like some panel mounts require a rectangular or round or oval holes and it's like, who has time for that? Round is best. So go to the overhead. I can show this real quickly. By the way, folks were saying that these magnetic things are great for the USB-C soldering irons. Oh yeah, that's a good idea. These are just really handy. Okay, so this, again, you just cut a hole. In case we have, if you can cut in these little notches, it just means it'll be less likely to rotate a little bit, I think, if you line it up perfectly, because there is a little bit of a grooving to it. But basically you cut a hole and then what's nice is this lip is 30 millimeters and this round part is like 23. So it covers up any rough edges on the cutouts. Like I was making an arcade machine and it's like if you cut the holes and then there's a little bit of a lip to it, it makes for a very nice, super pro. And then it's just an extension cord. It doesn't do anything special. It's just 2.5, sorry, 5.5 auto diameter, 2.1 millimeter inner diameter. So standard DC jack. Okay, next up, we've got more cables. Similarly to that right angle jack, I'm kind of like the magnetic cables have gotten better. They now do power and data and they're kind of advanced. So this is a cable that it's both USB type A and type C. You can cut this thing off or you can keep it on to make it one or the other. And on the other end is also a magnetic tip, which you can see on the next image and also here. So like that right angle adapter, this is a cable where this end plugs into your computer. You have Windows or PC, you have type A, you have type C, Mac, type C, whatever, either one. And then on the end here, the magnetic tip comes off, so it makes it easy for you to have this power, your dev board, and then here I'll even plug this in. There you go. There's a little indicator light and then, so let's see, so turn this on, this is lit, and then with this dev board, or I want to disconnect it without having to unplug, or I want it to just have a safety release so that the USB-C doesn't get yanked off the board, just release it and replace it. And of course it's USB-C, so you can put it upside down. So very nice, just magnetic cable. It's kind of your standard USB-C cable, but it's got a magnetic tip. Except... And it also has just the tip, so if you're like, okay, I want to have different boards with USB-C and I want to have one cable and then I can connect from one to the other, we have just the magnetic tip part. Okay, and starting the show tonight, besides you, Lady Aida, our team, our community, our customers, all the folks who make this thing go is... The TCA 8418 breakout board, which I'm really excited about because we started this design in 2020 and the chip was completely unavailable and then it became available. So we are able to finally stock this really interesting GPIO expander and a keypad matrix driver. So it is an 18 GPIO expander if you want to just have like 18 inputs, outputs with pull-ups and interrupt output, then you can do that. But what's interesting about this chip is it also does keypad scanning. So it has ten columns, eight rows, so it can do up to 180 keys. And here I'm just demoing it with a simple three by four matrix keypad. And it has a ten element event queue, so it can actually... You don't have to pull it constantly. If there's key presses, it'll record the key matrix presses and releases for you and then, you know, whenever you get around to asking over iSquared C, hey, what key presses did you get? It'll admit those key codes and whether they're pressed or released. And then you can use it with Arduino or circuit Python. We have drivers for both, so you can use it with any microcontroller. And then another interesting thing about this chip is it also has a Linux kernel support. And so if you happen to be interested in like making a up to 80 key keyboard for a single board computer, this driver chip you can load it with into the kernel using a device tree overlay. You can set up the key map. And then you can use it as a native keyboard built into the kernel, which I think is kind of cool. I'm going to try that out. So here's the demo. Just show it overhead. Fast. If I can plug it in. I should have gotten this hooked up to this big thing. So yeah, so here are the columns. So there's columns zero through nine, and then the rows are down here. There's two up here, row zero, one, and then through our seven. Note that you cannot change the row and column assignment. Like you can't make a column into a row. Like there's 10 columns, eight rows. That's it. And then, you know, I just happened to have a keypad. I thought it would be easy to wire this up. I just wrote a little example that maps the key numbers to digits and displays them. And there's also a debouncer built in. And of course you can mix and match. You can have some GPIO and some keypad matrices. Just again, you know, rows and columns are fixed. You can't change whether a pin is a row or column. Whatever it's labeled as is what it is. But it's a really nice little chip and does something that I haven't seen a lot of other. You know, GPIO expander that I know of, other than like the HT16K33 does keypads. Even that doesn't have a nice event queue like this one does. And that's new products.
