Projection over Hundreds of Metres
Laser projector with servos
We've already covered a laser projector in an earlier instalment of this series. This time however, we use a different projection mechanism. With a few servos, a laser module from eBay, a microcontroller and a little dexterity we can make a laser projector which, depending on the laser, can be seen from several hundreds of metres.
