Steve’s original 8x8x8 cube was based on regular tri-colored LEDs, which had to be time-sliced (multiplexed) in order to control them, thereby reducing their brightness. Since that time, we’ve both been experimenting with WS2812-based component.

If you like NeoPixel strips you’ll luv these 8mm diffused through-hole NeoPixels. All the single-pin-controlling-hundreds-of-LEDs goodness in a breadboard friendly format. Each LED looks just like your classic through-hole 8mm RGB LED with 4 legs, but instead of just red/green/blue there’s a little chip inside that can control the LED with high speed PWM for 24-bit color.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
