The ChromoDisk aka ColorMesh v1
... is a round PC board with 9 rings of 18 RGB LEDs each. The microcontroller and other components that make it work are in the center. The design is based upon the [Aurora Instructable]. Since I've worked with AVRs, and this seems like an interesting introduction to PCB design with LEDs, I decided to redo the original to fit into a 100mm dia board for minimum cost. I also designed it for a AA battery pack on the back side of the board. We'll see how long it lasts with 162 LEDs!
Current status: Boards in, first prototype done (5 hours to assemble!), writing software for it. Here's a demo of a simple program I wrote:
