Using two batteries in series will only overvoltage the 55 possibly destroying it.

How about the transistor; have you also tried replacing it?

Try monitoring pin 3 of the 555 using an oscilloscope, if you don't have one then you could try connecting a small 8

hm: speaker via a 4.7µF capacitor you should hear a buzzing sound.

audioguru · 17th December 2006, 05:18 PM

Yeah, the transistor is shorted or has its pins connected backwards.

oh right cool i will give it a go, cheers guys. i may have just overloaded both 555's and may need to use another one

I use it to zap any simple, kind, friendly and cute animals I come accross. They don't come back for more , they do not pass go ,they are not pests anymore.

I once was stupid enigh to discharge an 1uF cap wiled to 2kW in to my hand.It realy hurt and my figer was all red and hirt as hell.I never even dared to toch it whithout puting an screwdriver over it first.

Experienced member huh?

Who would accept advice from someone who wont take the time to spell words at least reasonably closely. It takes no longer to spell it out fully and trying to read this rubbish seriously is bloody frustrating to put it nicely. Can't you make it a little more readable ?

Go easy on him. It's obvious that 2kw shock took its toll on him.

did you find it ?
if you find it please send me the details
thanks

Is it the output transformer used in pockect radio sets?

Thanks

The circuit must be 40 years old. Travel back in time about 40 years and buy the transformer. It is not the output transformer from a little portable radio.

I remember 40 years ago when I could buy the transformer at the electronic parts store. I know a surplus electronics parts store that has lots of old junk and I bet they still have some.

But the circuit will not make a stun gun. It will just make a little spark.

Hmmm, some serious irony there. Since when did "simple, kind, friendly and cute animals" equate to being "pests"? Geeez, I hope you don't apply that philosophy to humans!

What is the application of stun gun........?????

A 1 MEG variable resistor can also be used at the output to drop the voltage, but this is optional. If you build this circuit, be careful, as it outputs a high voltage. Touching the output leads will induce a painful shock.

NOTE: Building stun guns can be very dangerous! Please use caution.

you're "stunned" when you discover that it doesn't perform very well for the time, effort, and cost you wasted on it.

audioguru · 2nd March 2007, 04:05 PM

This circuit is not a Stun Gun. It is just a little spark generator.
A Stun Gun makes a continuous high power high voltage shock.
This little circuit makes a very weak shock.

You can make it any way you want.

That is sick, although having cruel thoughts about one of the neighbor's cat's... Craps in my yard, usually in a high traffic area (guess the grass is shorter), and doesn't bother covering it up. Every cat I ever owned made such a huge deal of digging out a hole, then filling it over when done. This one just squats and drops, and walks. All usually quicker than I can notice on the security cameras.

Wonder if this cat would be stupid enough to eat out of a metal dog bowl...

audioguru · 2nd March 2007, 09:58 PM

I doubt that even a stupid cat would eat from your metal bowl that makes "crackling" noises.

Hero999 · 2nd March 2007, 10:11 PM

I've read that cats cover their crap so it doesn't offent the dominant animals (their human owners). Perhaps the cat that craps in your garden is an alpha cat, it's probably either a stray or it has its owners under its thumb or perhaps I should say claws.
