Low budged laser projector

This project seems to be quite fun, because it is pretty easy to build. All you need is couple components including laser pointer, cooling fan with mirrors, MCU, and optical sensor. As there are seven mirrors glued to fan, projections can be drawn out of seven lines. Each mirror is adjusted so that all lines are horizontally aligned.

Next comes to Arduino which reads optical sensor data to determine when first mirror passes and then blinks synchronized image or other effects.

  1. Very good and creative project. However, I think timing of the laser pointer is a big deal
