Spinning LED ball (RGB) HELP!!

Question

Hi all,

Does anyone know what the components list and plans are for this project?

Or can anyone find them?

It seems like an interesting project to try.

Cheers,

Chris

Hi Chris, That is a great video, but it looks quite complex. I would start with something quite simple and build up. Pick a microcontroller first, and learn how to use that. The Multicomp Arduino clones, the Amicus boards and mbeds are a good place to start. That would give you a choice of PIC, AVR or Cortex processors. Start form scratch and learn how to control hardware from the chip using software.. I've a degree in electronics but not practised for a while. I bought a book recommended to me on another thread on PIC 32 programming. I'll get a starter board, and then I will build up something simple and build on from that. I think you sound more interested in getting a recipe and throwing it together (which is fun), but in the longer term it is more satisfying to know how and why stuff works, and be able to tailor projects to suit your own needs, than trying to suit your needs to the project.

This project doesn't look like one of those spinning wheels that displays an image or text, so it should be fairly easy to accomplish. PWM of two motors. Control 3 LEDS, and you don't have to do any major timing calculations of them either. That's it. I'm just curious about the coupling used to control and deliver power to the LEDs while spinning. Let me know if you find out how they do it. Cabe
