[Nick] wrote in telling us about the LED cube he built over the course of six months. He calls LED cubes ‘done to death,’ but [Nick] might be too humble. His 8x8x8 RGB LED cube is the best we’ve ever seen.
To start his build, [Nick] built a simple 4x4x4 cube as a proof of concept. The baby cube worked but the fabrication process got him thinking. Instead of building his monster LED cube in layers from the bottom up, he would need to build columns from left to right. After the construction of a jig, soldering eight panels of 64 LEDs, and buying a new soldering iron tip, [Nick] had a beautiful assembled LED cube. The only thing missing was the electronics.
Most of the LED cubes we’ve seen use the TLC5940 LED driver for hardware PWM, [Nick] decided to go with the simpler but more familiar STP16 chip. After hooking up his huge LED driver board up to a chipKIT Uno, the 80 hours of programming began.
In the end, [Nick] built the best LED cube we’ve seen (even though it isn’t the largest) and put together one of the best build logs in recent memory. Because no LED cube build is complete with out a video there’s an awesome demo after the break.
