Our friend Carl who has been featured here many times in the past for his laser projects has made an improvement to his Spinning LED creation. Have a look at the new Spinning RGB LED Ball.
"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."
