Arduino Laser Projector

A laser projector creates a light show that seems to be coming from dozens of laser beams. It only needs a single laser beam to create the effect because the beam is diffracted as it emerges from the projector.

This project shows how to build a laser projector using an Arduino, a heptagon pillbox, a cooler fan and a laser pointer. Making your own laser projector requires a few parts from a laser supply house and some skill and knowledge of electronics.

The creative use of a heptagonal pillbox for a polygon greatly reduces the overall cost and complexity of the finished device. The projector can only able to display dot matrix messages.
