Data and power signals flow around the cube via solder connections along the edges of the faces of the cube. Running the show is an ATmega328P, the same microcontroller you’d find in an Arduino Uno.

He’s using an Arduino Uno to control the display, choosing TLC5940 driver chips to safely provide the juice necessary to light up the grid. These drivers also offer 12-bit pulse-width modulation ...

This 8x8x8 LED cube with 512 LEDs takes the old 3x3x3 light cube made up of 27 LEDs to the nth degree. This, certainly more time consuming project, actually involves a simpler design. By using a ...

This is a pure 3D display -- unfortunately done at a resolution of just 8 x 8 x 8. It's a hand-built LED cube created by Nick Schulze, powered by Arduino, and driven largely by Matlab.
