I love this RGB POV in a tube created by rucalgary.

There are 64 RGB LEDs spinning around on an aluminum frame, spun by a motor picked up at Princess Auto for $20.

I control everything via an ATMEGA1284p microcontroller, as it was one of the only micros that had the memory space I needed for images.

I hope to get some more color out of the system by PWMing the color output, but we will have to see that later. Right now I am displaying images just by changing the source code, but I hope to get wireless updates working over Zigbee or Bluetooth.

You can download the code and Eagle files if you want to learn more. [via EmbProj]
