Color Stick
The color stick is an 8-pixel (24 DMX channels) LED display. Each pixel is made of two RGB 5050-sized LEDs; the LEDs can either be loaded on both sides or all on one side.

In addition, you need 16 5050-sized RGB LEDs; the ones from the group buy are ideal. Mouser 593-VAOS-5050RGBW1 would also work, but the channel mapping of red and blue would be reversed.
