Musical Tesla Coils

blog-0877462001397183781.jpgI just found a video of a man playing a Tesla coil as a musical instrument. With a guitar. Basically, the guitar still works the same way but rather than sending its MIDI signals (notes and such) to an amp, it is being sent to a Tesla coil. Tesla coils work by sending alternating current through a wires coiled into a torus (donut shape). The changing current charges a larger torus trough electromagnetic induction. The voltage induced in the second coil is much greater than the first which allows a capacitor to be charged to the extreme where it trows visible electricity to the nearest conductor. When the coil is turned on it makes a noise, so the trick to making music with a Tesla coil is to alternate current at a frequency at which our brain can interpret music (it turns out to me about 440 hertz). Notes can be created by modulating the amplitude of the current. In the case of the guitar, the players input on the strings is used to modulate the amplitude. Here's the video i was talking about:

And then I found this and my mind was blown...

METAL!!!
