TO generate shocks, all you need is a simple clock circuit (CMOS SCHMITT 
INVERTER WITH Variable R and fixed C
Then a transistor to drive an autotransformer or simply a inductive coil 
with a small tap for the driver and the large turns for the secondary ZAP
The energy is proportion to the Inductor size and current . It can be 
fairly tiny. A low freq is only necessary <200HZ. But remember battery 
power will increase with frequency. Aar ignition coil would be overkill 
to say the least. Try it on your self before using!!!
