This instructable covers building the kit that is the result of several builds, and many iterations. If you want to learn more about previous attempts and or the design process comment below and I'll dig out the older (and much much smaller) versions and also go through the design and manufacture process too. But this is really a kit build but of a kit I've built.
I've always wanted a Larson scanner. Growing up watching shows like Battlestar Galactica, Knight Rider and even the A-Team (there was a gold Cylon in it, Face does a double take at it which was a nice touch!) it's hard not to have fallen in love with the hypnotic bouncing light invention of Glen A. Larson.
