It's a ball of LEDs that spin, real fast.
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.
