DIY: Bob Clock


A Bob Clock is a wall clock that  uses 60 multi-color LEDs arranged in a circle to represent the small and big arm of an analog clock. You can make this cool gadget at home and for full instruction go to Symlink.

“On this version, the blue light signifies the hour-hand, while the red one is the minutes, so in this image the time is about 10 minutes to 4. When both the minute and hour arms are in the same position, the colors will be mixed. On this version it turns out as a purple color.”
