Wow, here’s an awesome laser DIY that shows you how to make a 7-color laser. Yes, a laser that can shoot out 7 different types of lasers. I guess the creator of this laser followed the directions from here and you can see the results here.
I just went for the 7 color laser, not the spiro. How Rog gets all of that to fit into his small box is beyond me. I thought I would share just a couple of things I found out doing this build.
