Wow. I thought I’d never see a breadboard ever again after graduating from college, but I guess I was wrong. Well, at least it’s being used for something really cool, like the Plasma Speakers. Unlike traditional speakers which compress air waves (to generate sound) using magnets and flexible cones, the plasma speakers use “the non-gas, non-liquid, non-solid ‘fourth state of matter’ plasma” to generate the compression waves. Running at 50W, the speakers are set at a frequency response range of 200Hz to 12kHz.

If you thought that was cool, check out a pair of tesla coils playing the classic Super Mario Bros. tune after the jump.
