Arduino Laser Dymo Clock

An original arduino Laser Dymo Clock

Original clock this!!

Using a UV laser, two stepper motors, two ULN2803 drivers for the motors, an Arduino,a "daisy wheel" print on transparent film, and some luminous paper, this project has achieved a very original clock.

This system opens up new paths to other projects: Perhaps a reader of tweets?
