While the gold standard for colorful blinky projects are individually controllable RGB LEDs, the usual offerings aren’t really that impressive. Yes, a few hundred Neopixels, WS2812, or other RGB LEDs will sear your retinas, but what if you wanted blinky glowy stuff that is so over the top as to be an affront to whatever creator you believe in?
This is it. [Ytai Ben-Tsvi] created an individually addressable RGB LED called the Pixie that is perfect for all the times when you need something bright, colorful, and want to blind a few people in the process.
WS2812s and Neopixels are basically RGB LEDs with a small microcontroller tucked tucked away inside, and so far there is no design house or fab plant in China that is crazy enough to add one of these tiny dies to an already overpowered LED. To build the Pixie, [Ytai] took a bare RGB LED module and added a microcontroller – a PIC12FF157X in this case. It’s not exactly a powerful microcontroller, but it can handle the shift register-like function of an individually addressable RGB, and adds gamma correction, over heating protection (something necessary when you’re dumping this much power into a tiny board, and other safeguards for each individual LED.
[Ytai] is working with Adafruit to produce these Pixies, and although they’re rather expensive at $15 per LED, you won’t need very many to blind yourself.
