 Okay, this week, this is one that we just filmed. Just a few... Just testing on a profile. It feels like moments ago. Here it is. It was a guess, yeah. Apparently, I know what it is. I'm testing out a new design I made. We actually just published a project that uses WLED on an ESP32 cutie pie, and Erin was like, oh, I wish it was an easy way to level shift Neopixel signals for LED work on cutie pies, because they're all 3-volt logic and Neopixels really want 5-volt logic. So I made this a little BFF, this is a little backpack. You can select different signals, you know, MOSI, SCK, RX, TX, SCL, and A3 are some options, and there's also a signal pin here. And this is a 74-HT125G1 level shift, or sort of shift the 3-volt signal to 5-volts, and then it also gives you a 5-volt signal from the USB line. So, you know, for strips of up to like 100 pixels, you might be able to power directly from USB for clean Neopixel signaling. Okey-dokey, and that's this week's top secret. I got a bunch of questions. We do, I have some wind up.
