 What's in the vault? Well, I'm gonna play two videos back-to-back and then we're gonna look at one of the boards you just posted Yep. All right lady. What is this? Hey, this is a older product. We've made. This is the Charlie Wing It's got an I squared C to 15 by 7 LED driver that can do 8-bit PWM for all these LEDs Which is great for like, you know monochromatic LED projects. You can see the nice Dimming of each LED, but there's a new chip. This is the 3731. There's the 3741 from ISSI and this one is full-color because it can do so many more LEDs It can do 351 LEDs and you can divide it up Here's the chip itself and here's the LED matrix. I'm actually driving it from this Metro Mini and Yeah, it's a 39 by 9 Dot LED driver, but you can divide this by three. So it's 13 by 9 RGB LED driver, so a lot of LEDs is often used in some keyboard. All right, Lady data. What is this? These are some cool wireless LEDs. You'll notice that they have their LED soldered onto Inductors, right? It's like a 2.2 micro Henry inductor and it's an LED capacitor. So how are they lit up? Well, there's this gigantic coil underneath. This is like an inductive charging system But it's split in half so that this is the large coil and it's powered from 24 volts And these are little LEDs that when they're within like a foot or so of the coil I can move up and down and around They light up. So these are used by model makers a lot, but they could have some like cool jewelry or like Installation or aesthetic purposes. I'm kind of neat You can see they can you can move them around anywhere in the open space of the coil And they stay a lit Pretty neat All right, and then you have these three Things that well, there's there's two and in the back So I just I'm making you know I'm trying to get back into down my stemmyqt game I was doing one a week and then I kind of got distracted a little bit because it got nice out So getting back into that our two popular RTC boards I sort of reimagined them but in stemmyqt format and will battery holder on the back All right, that's up secret.
