 And the vault. Open the vault. Seek the vault. Okay, what do we have? That's right. So, first up, you all, I mean, it's your show. What is this? Okay, so I put together, I'll show this on Descalade 8. It's MCP 23017. This is a 16 channel I expanded for I squared C. You know, it comes in dips, so you'd think like, what's really the point of having a breakout? A lot of people were like, no, I really want to have something that Stemma plug and play. We get a couple of requests for this more than I was expecting. And so by the third or fourth request, I was like, okay, maybe I'll whip together something to make it even easier to use this very popular chip that we have drivers for already. All right, so this is, when I filmed this with Top Secret, but now we have the product. So we'll just get a view. This is like a little time traveling. Yeah. Behind the scenes. Okay, Lady, what is this? Okay, we're putting together some new boards. This is the IS31FL3741. It's a PWM LED RGB driver that can do a lot of LEDs. This is cool because it's much cheaper than individual dot stars or near pixels. So this is the prototype, which I hand assembled and it's a little like wobbly. And this is the nice ones that just came off the pick and place, a little toasty even. So let's try out our test code. Plug into our Metro Mini. And... One moment. There you go. You can see a nice demo showing text and color gradients. We're also testing two RGB LEDs. These LEDs are only a penny a piece, but there's a slight variation. One's a little brighter than the other. We're getting this ready to put in the shop. It's a cute little RGB LED matrix that's all powered and controlled over I squared C. Stem a QT. And then I have this demo. This is... If you saw the show in Tullin, which Trevor was working on, this is basically that video. And this is our new app. It's in beta. It's in test flight. And it's called PyLeap. And the idea is we'll make putting code on a Bluetooth device as easy as we've had. Putting code on a circuit python device where it just shows up as USB drive, drag and drop. But this is even easier where all you do is turn on your Bluetooth device, load this app. You pair it. And then what we have is code that's on our learning system. And you just choose what you want to do right now. We're doing this in Rainbow's demo. It takes the code from the learning system, downloads it to the phone. Do you have the latest code? And then it sends it right over to the device. And so that's how quick it is to get code on without a computer. And that's this week's stop secret. Okay. Get back in that vault.
