Everyone at some point in their life has seen a CD clock, right? You know, a clock, made from a CD. I’ve decided to try making one too, but using an entire CD ROM drive and some funky electronics to do it. I was inspired by the Hard Drive Clock by Alan Parekh.
Front & rear views:
Basically I’m using the motor and CD holder from the drive, as well as most of the original chassis. I’ve hacked up the motor so an RC hobby brushless controller will spin it, and I’ve got a clear CD with a hand etched into it (you can see it in the ‘back’ image). I’m going to write some microcontroller code to run the motor, sense the RPM, and strobe some LED’s at the right time (like the hard drive clock does) to make the display.
I’ll post more as it (hopefully) comes together.
