I happen to have some old 12 inch optical disks made of glass. So when I saw Terry and Adam Clarkson’s ClockOS project on Kickstarter, I recognized the potential for an awesome clock!

The ClockOS board is Arduino compatible and hosts a ring of 180 surface mount RGB LEDs (in 3 concentric rings of 60).  Modes can be set through 3 buttons on the back side of the board.  The onboard Atmel168 can be programmed by attaching an FTDI cable.  An onboard PIC18F25K22, which helps drive the LEDs, can also be reprogrammed through an ICSP header.

As you can see from the photos below, the ClockOS board matches up nicely with the optical disk.

The video below shows several of the clock faces (and the ClockOS board) in action (the LED flicker is only an artifact of the video).

  1. Been throwing this idea around for awhile now to use a laser disc for my clockos and came across this masterpiece!! Great work! Is this a laserdisc? I’ve been searching everywhere to find one like this and can not find one anywhere that look like this. All laserdics I find don’t have the discreet lines across them like this, look like they’re not made of glass, don’t have the center that this has, and don’t look like light would pass through. Please sir I have to know what kind of disc this is. Truly awesome!

  2. Yes, this is a laser disc which was once utilized in a very large room-sized optical storage system I once had the pleasure to disassemble and salvage parts from. The disc is glass and was removed from a large plastic carrier which encased the disk originally. I believe these were made by Optimem.
