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 … ...

An Arduino can handle running a small LED cube on its own, but if you’re planning on building something big, eventually you are going to run out of pins. For something like an 8x8x8 cube, odds ...

As spotted by Hackster, this cool cube comes to us via OhmBrew. The creator had previously made an 8x8x8 version, but wanted to revisit it and add an extra layer all around to make it a 9x9x9 LED ...

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.

This massive LED cube contains over 4,000 individual lights and is able to make mesmerizing, three-dimensional rainbow patterns.
