Home Laser Show
Geof Milburn is completing his engineering master’s degree at the Royal Military College of Canada. He was the maker of the homebrew air conditioner from several years and has kept up at his tinkering. He made a couple more neat projects and lucky for us, he documents them quite well. He calls the focus for today “The Ultimate Home Laser Show.” He does away with all the fancy electronics to aim the mirrors and uses a mirror stuck on a speaker. It provides more than enough movement to make the laser dance. Then the beam is shot through a diffractor and you have your light show.
