Blinkenlights cube
Oct. 5th, 2013 05:53 pmI finally got around to building an LED cube. My parents got me a kit for one of these a few years ago and I never got around to building it. Actually I still haven't; I got a much easier-to-assemble kit from Seeedstudio instead and built that.
Here's a short video.
It's a very clever design for a grid made of very thin, delicate printed circuit boards. You put all the LEDs into it (64 RGB lights, although the video just has them being white), then connect the four layers of the grid together with more thin boards, then solder the whole cube to a base board, and that plugs into an Arduino (a special one with specially-placed headers).
What's cool is that unlike the other kit, this one is totally programmable. The Arduino has a library that controls it, with functions like

Rb.setColorZXY(z, x, y, red, green, blue). It has a few different plasma effect demos and a mood lamp and stuff; last night I spent a couple hours hacking together these Blinkenlights.
