Tiny RGB LED cube

LED cubes are cheap and great approach to 3D visualization. All you need is a hand full of single color or RGB LEDs and microcontroller. We’ve seen lots of interesting projects that use standard through hole LEDs that already have legs allowing to solder a cube grid. But there are not to many attempts to build cube with SMT LEDs especially with RGB.

Hari Wiguna decided to build a tiny RGB LED cube as a module which could be driven by microcontroller platforms like Arduino. Since RGB LEDs are already three LEDs packed in, he build 4x4x4 configuration which already require 64 LEDs. If we count individual diodes there are 192 of them. So controlling them all already is some task. The size of cube is also tiny – cross cut is same size as quarter coin. When you squeeze the cube you very quickly loose the 3D effect, since diodes start masking each other. In this case I think this limit is quite reached, because SMT RBG LEDs aren’t transparent. Anyway it still allows creating lots of great effects. And yes soldering SMT LEDs in to cube seems to be a nightmare.
