Working with Lightsabers

Pretty cool!
We modified circuits inside a miny battery-powered sword/light-saber. First we took out the two main screws and studied the different components of the toy. There was one speaker, and LED, a green circuit-board, two lithium batteries, and a tube acting as the crystal shaft. I could modify the sounds the lightaber made. All in all, I felt like a three-year-old again in a long time. In the end, my unfortate partner possessed a sword which sounded like a repetitive machine gun which drove me and all the other room-mates to heaven. Uh-Oh, there it goes again! See ya in heaven!
