Spinning RGB LED Ball II
So you want a project with lots of moving LEDs?
From: laserpointerforums.com ============================ It was very hard to build! I has a lot of problems with the power transfer and failed may times before I got everything working smoothly. Now it runs like a dream. I made it all from very simple materials like wood, VCR-parts, fans, junk, antenna tubes and a lot of solder!
Total of 9 slip-contacts, not including the motors! The current for the LEDs has travel through 6 slip-contact without glitching! It took about a week to build.
