I've made a few 'camera tasers', and they are actually very inefficient as there 330~ volts, and cannot penetrate clothes, and it is a cap discharge so the current is wuite dangerous too, I was thinking is there such thing as a 'mini flyback' and a driver for it?

....Yeah, use a camera taser, with a smaller capacitor. It'll give the same voltage shock but at much much reduced current levels.

Or, try finding a really really really small cap, and use a flyback to charge it with the appropriate voltage levels.

See, coming with a electro shock weapon isn't exactly safe. There is no "safe" way of electrocuting someone, because everyone is different and thus reacts different to an electrical shock. Some may just say ouch. Some, if wet, may actually go into cardiac fibrillation, and could die as a result. So, in general, try not to make any electrical shock weapons. Find some other way that's not so dangerous.

Think about it; why are tasers so controversial?

I really wouldnt mess with this kind of thing.....skin resistance can vary so wildly, from 100kohm for dry skin, 1-10kohm for wet, and as little as 100ohm if you happen to draw blood (which then links directly to the heart).

Yes, say you would make a flyback powered ES weapon, and the plasma burn skin and draws blood, the current although low from the flyback can be deadly, how would a 400v 2uF cap be on a camera taser?

A low powered flyback driver to charge a capacitor. Not the flyback itself. That's dangerous.

So a 400v 2uF will hurt, but be harmless?

I dont know how to work out amperage from caps.

I just wouldn't use it at all to be honest. It's too dangerous and unpredictable.

Would this have any high voltage components?

Ever noticed how taser guns are referred to as less lethal, as opposed to non-lethal? You just cant give a person a noticable electrical shock and still guarantee his safety, because how a body will react to electric currents is notoriously unpredictable. Even the smallest shocks can kill in extreme cases.

Considering this, its not difficult to understand why the members of this forum are hesitant of giving you schematics and exact capacitor values and such.

I read in your previous thread that you had shocked yourself with a 100uF capacitor charged to 400V. That's nasty, and it sendt an eerie chill down my spine. I dont want to be mean, but reading through your previous posts i cant help but thinking that you might not fully understand what you are dealing with. I'd advise you to put the taser idea on ice for now, and gain some more experience playing with safer projects.

To be honest, I'm actually going to leave this stuff alone, and I'm going to build a another Flyback SGTC.

Yes I was shocked with a 400v 100uF cap, by accident, It burned a hole in my finger, it knocked me on my ***.

Can TC's be powered from Ignition coils?
