Decreasing the current of CCFL Inverter

[thealienx]

Hi,
Sorry if this is not the right lane.
i have a ccfl inverter with ccfl tube, picked from a scanner unit.
i want to use the inverter circuit for a non lethal shock gun.
i have gathered some information on safe range of current in human being.
------------------------------------------------------------
In general for a normal human:
1mA(mill Ampere) or (.001A) of current can be felt.
5mA of current can be painful.
10–15mA, the person loses muscle control.
If its above 50mA then it would fatal.
100mA above would be lethal.
------------------------------------------------------------

Please see pic for Inverter.
some technical articals says about 5ma is used to activate ccfl tube.
i want to decrease the current to a safe level (1 0r 2 ma) for my project. can someone help me in how to do?

Thanks

The figures you've quoted are for power line frequencies (50 to 60Hz). The CCFL inverter will output a much higher frequency (>20kHz) which is less likely to cause an electrical shock, even at greater currents than those listed above. The only hazard is heating: it can badly burn you and penetrate very deeply into the flesh.

You could reduce the value of the capacitor in series with the tube (the blue one in your picture) but 2mA at 20kHz would just feel like touching a hot object, if the the contact area is small, or nothing at all, if the contact area is large.

To build a shock circuit, you'll need to add a rectifier and smoothing capacitor to the output. A voltage multiplier would be a good idea, as higher voltages are required to penetrate think clothing. The capacitors shouldn't be too large, otherwise it becomes deadly.

This is completely wrong thing to be used as electric shocker. Moreover inverter is not made to run open or short, it will fail very soon. The only thing will happen to you if you try to use it on someone, it will end up in your butt.
