Spinning RGB LED Ball

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.
