It's a ball of LEDs that spin, real fast. *** I'm sorry that the music as been changed, but I was having copyright problems and the video was blocked in Germany. Old audio was DJ Tiesto - Adagio for strings. *** Unlike it's predecessor this one has three axes. It was very challenging to build, with a total of 9 slip-contacts, not including the motors. I made it from scrap I had laying around and it took about a week to build. I use standard DC-motors controlled with pulse width modulation, the LEDs are controlled with a modified bike light with adjustable frequency. I'm very sorry about the quality, my camera can't keep up and it makes a lot of flicker that isn't really there, and the LEDs oversaturate the image.
