I have a pretty good background in electronics and robotics and have 
decided to build a tesla coil. I have done few things over 500V and 
after seeing a friends tesla coil in action I decided it would be 
pretty fun to buld my own. He has a website by the way teslafun.piczo.com

Just started building my coil the other day, It'll be my first.  Its 
going to be portable enough to fit in my duffelbag and so far uses 3 
parts (a 7.2V batt, a relay, and an ignition coil. the relay is setup 
to "buzz" for lack of a better term) and gets a 1/4" to a 1/2" spark 
off the ignition coil HV lead depending on random things (its far 
from reliable).

I was wondering if anyone knows of a reliable, solid state circuit 
that i could drive the ignition coil with? One thing that I want is 
that it doesn't plug into the wall and can be operated at 7.2V or 14.4V.

relay------- home-made, guess-timate 120 amps, 500V
ignition coil-----63KV,1ma  off of 14V, 2 amps

Batt--------- can supply up to 120A at 7.2 volts or 14.4V for 5 
minutes. Tested by me
