Three Watt Individually Addressable RGB LEDs

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.

Millennium Falcon doll house

Sometimes all it takes is one idea. The shape of a cutting board found at a thrift store prompted [Paul] to build a Millenium Falcon doll house. In addition to the strangely shaped cutting board, a ring from a CD spindle and some wood slats divide the internals while PVC fittings complete the cockpit assembly. To really bring things alive for the kids [Lin] made a bunch of minifigs from hobby pegs. These exhibit her artistic skills as we think they’re better than most of the stuff you could buy in a store.

Kids really bring out the best in hacking. Looks like these children have been enjoying the spoils of hacker parents for a while, with a cardboard rocketship (beats any refrigerator box hands down), Pixie-Dust bottles using some small LED bits, and a doll bed that repurposes a wine rack.
