The Tesla Gun

Oh man, check out this awesome hand-held Tesla coil, a.k.a. plasma gun. Details:

A Power Pulse Modulator circuit is used to drive two small high voltage ignition coils wired together in an ‘anti-parallel’ configuration. The output is rectified and used to charge the tank capacitor of a small spark gap Tesla Coil.

Cool how they used a cordless drill as the power source, trigger switch, and housing.
