but i couldn't get the square waveform... is the problem come from the IC or the TIP31?
what i get is an unstable waveform...

jonkbu

what is the transformer code?

For a much easier and pre-built stunner (shocker), why not just use a disposable camera?

Remove the flash capacitor then take wires off where it was then attach to bolts/prods/screws (whatever floats your boat).

You also might want to solder the flash charger switch contacts together if you are putting the camera circuit in another enclosure.

1.5v battery gives around 1000volts. Enough for you to feel it. Up the battery to a 9v and see how ,long before you get tears in your eyes.



CAUTION!: Discharge the flash capacitor FULLY! It will bite you hard, if not kill you!

EDIT: Ah right, i see the camera shocker has been discussed. I thought that's what we were all after.

I would like to know what is the difference between inducing a shock with high voltage and low current (i.e. 1800V), and inducing a shock with a high current (20mA - 100V) and low voltage.

First off, That particular 1800 Volt circuit is absolutely USELESS. It has almost No Current and 1800 volts isn't enough unless you contact Bare Skin.

Second, 100 Volts at 20 mA Can Easily KILL the person.

Ideally you need High Voltage to Penitrate the persons Clothing so the person gets a Shock. And a reasonable pulse of current so it HURTS but doesn't Kill.

What I want to build is a device that has, say an electrode that I touch it with my finger and i can send an 'electric shock' but NOT painful or disturbing, justto be able to feel the 'electric sensation.
Could you suggest something?

Thank you in advance.

Everybody is different. Some people are barely alive and are killed by the slightest shock. Some people die just by thinking about being shocked.

Then you will be charged with MURDER! (Unless you can prove that the person died just before you shocked him)
