8X8X8 Cube Invaders


Believe it or not, [Anred Zynch] had no soldering skills before starting this project! What we’re looking at here is an 8x8x8 LED cube set up as a Space Invaders style game with a Playstation 1 controller.

He was inspired by several other cubes like [Chr's], and the Borg cube by [Das-Labour]. The project makes use of an Arduino Mega 2560 R3 to drive the 512-LED array, and an Arduino Uno to take care of the sound effects during game play. It’s kind of like Space Invaders — but in 3D!

Complexity of building and wiring it aside, [Anred] has provided great instructions and the code for the entire project, so if you’re looking to recreate it or something like it, you can! It’s also entered in an Instructable’s contest right now, so if you like it, we’re sure he’d appreciate the votes.

8x8x8 LED cube and the board that drives it

Check out the LED cube which [Thomas], [Max], and [Felix] put together. But don’t forget to look at that beautiful PCB which drives it… nice! But hardware is only part of what goes into a project like this one. After the soldering iron had cooled they kept going and wrote their own software to generate patterns for the three-dimensional display.

Looking at a clean build like this one doesn’t drive home the amount of connections one has to make to get everything running. To appreciate it you should take a look at this other 512 LED cube which has its wires showing. You can see from the schematic (available in the project repository) that all of these lines are managed by a series of shift registers. The board itself connects to a computer from which it gets the visualization commands. A Java program they call CubeControl can push letters or turn the cube into a VU meter.

The team built at least two of these. This smaller version uses red LEDs, while the larger one shown in the video after the break has blue ones.
