SHOW ME!!! PICS!! lol... also is the stun gun suppost to give u like one shock and thats it...? or like a simultaneous none stop shock untill u let go of the output wire.. lol....... im like really a noob at all the parts still so im like slow wit the stuff.. i can read schematics and if u give me the right parts im set.. but usually ill mess up if i have to search for the parts myself

if someone could just tell me all the parts i need to use.... i know theres a list on the schematics... :-/... but if there is anything else i should be using to make it work right let me know... also i mentioned im using a mouser transformer if there is an alternative besides the mini audio transformer 200k to 1k ct in the schematic let me know! ive been trying to make this stupid thing for like a month now and its driving me crazy.. I NEED TO FINISH IT

I Can't believe all the questions and comments here for such an Old, Simple and Useless Circuit.

Quote: "mini audio transformer 200k to 1k ct"
Not even sure Why anyone would Specify this Transformer or any transformer rated in Impedance?

You want to STEP-UP the Voltage, So what is Most important is a High Turns Ratio to get a High Voltage Output.

Impedance is NOT a Turns ratio, it is an Impedance Ratio.
Impedance is basically an AC Measured resistance.

And with a little effort and the use of your brain, it could be built and working in 15 Minutes. Not that it will do much of anything in the way of a real shock to anything.

If you want a Real Stun Gun, that circuit is Not what you want. There are some More Professional Stun gun Circuits on my website, But you can't just BUY the Transformer for them. "You Must make it". And that requires Considerable Skill and some special equipment.

Hi Gary,
The 1k primary impedance is actually only 250 ohms because half is used.
The impedance ratio becomes 200k to 250.

The turns ratio is the square-root of the impedance ratio. So the turns ratio of the little transformer is 28.3.

You can double-check by calculating power input and power output which should be nearly the same if the transformer is half decent. A 2V signal into 250 ohms= 16mW. The 2V signal multiplied by the 28.3 turns ratio into 200k ohms= 16mW.

If the little transformer can withstand the high voltage, its output power is very little.

But an impedance transformer has a turns ratio just the same, the ONLY reason this transformer is specified is because it's so easily available (or at least it was in the ancient past when the project was designed).

However, I would fully agree it's a crap circuit! - but it doesn't bother me as such devices are SERIOUSLY illegal in the UK (jail time type serious!).

audioguru, Yes I am well aware of that formula.
But that is Still a Crappy transformer.

A small power transformer would be better and a 220 volt to 6 volt should be fairly easy to get, Back than and still today.
With a Bit Better output, Both for Voltage and Current.

But Still No where near being a Stun Gun.

But a Good "Tickle Stick".

Nigel, Not Sure What your Problem is:
But "Tickle Stick" was a Common name applied to these Low Powered, High Voltage circuit MANY YEARS AGO in Popular Electronics and Other Electronic Magazines.

I've no problem, and wasn't referring to you - but to what would happen if a builder tried to use the audio transformer 'stun gun' on someone.

Probably just an American term then?.

A tickle stick? That's got to be a term straight out of Sweden or Denmark!! I seem to remember that they can operate from alkaline batteries. The ticke stick industry strongly recommends using inexpensive carbon-zinc dry cells over pricey alkalines do to the extreme power capability of the alkaline types.....

remember that past thread?

Hi there, i am having trouble finding the EC104M SCR on your schematic, i cant find any suppliers on google either, is there an alternative part number?
also with the transformer, is the bobbin used for winding the cores only? or does it stay on, with the fair rite core slipping in the middle of the bobbin.
Cheers

A 555 timer, a FET, and an ignition coil is way simpler and a lot more fun.

 

I'm never create one of them.
It seems dangerous.... I don't want these american stick touches my face
What about killing-gun that kills any mosquito. Just make it stronger, and it will kill animal too.
