Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to … ...

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.

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.

Maker constructed a 9x9x9 LED cube that can display games in a 3D space. It has custom gamepad support and a 3D rendering engine, giving a unique gaming experience. Simple games like Pong and ...
