Stun guns use a very basic approach to the Tesla Coil (which never quite
reaches it), in that a low voltage is oscillated at a high frequency,
fed into a step-up transformer (the high frequency requires a much
smaller transformer using a ferrite core), filtered, and delivered to
pointed output terminals. Some use a capacitative discharge system which
requires a high voltage trigger; normally a small neon tube. This is the
first I have heard of that uses a spark gap... perhaps I am falling
behind the times.
