Thats right, in fact you can hold onto it and feel quite little, but if you let all the caps charge up a bit, then it gives quite a shock.

Plz give a also Circuit Diagrame of stun gun so i can easily understand

hey. i'm new to this forum. i signed up to find out about this project. i actually want to create mark stoker's model as a defence unit. it seems a much better idea than the traditional thing people do in my area, which is carrying knives :S !

i'm going ot have trouble finding the transformer. could somebody please tell me wha tthe specs will need to be for things like the capacitors and resistors? will i need parts with higher tollerances or can i use tiny ones? also, the 1n4007 is hard to get your ahrds on here, i used a 1n4004. will that do the trick? any reason for such high voltage tollerance? last thing! i'm such a noob, but to save me looking it up could someone please tell me which leads on the tip31 are the c/b/e ?

hehe.. thanks guys (: if this works well i'll make a pcb for it.

this is what i have so far (attached)

LMAO, LMAO you don't know how funny that comes off as!!! A few years from now, you'll finally know if you have full function.... that is of the neuron flow in your body! You should sharpen those contact points for two reasons:
1. breaks the skin to deepen the shock's effects
2. might as well leave the poor bas"turd" bleeding as he lies quivering and convulsing on the pavement!

Too funny HiTech..

I have a neighbor that shoot a BB in his hand, (I asked) he said I thought it was empty (so he pointed it at his hand).. OK, I have a STUN GUN. Let me see if it works. BBiiiiiiiizzzzzzzzzzzz!!! What day is it.. Uh, yep it works.

ElectroMaster has a sleeper going here, 4 pages.. Almost as good as "let's change the forum layout, your thoughts.". Maybe that is why he made the stun gun.

I must admit, it is a cheap circuit to zap the tar out of someone though.

Saturday I got nailed by a stun gun: 25kv CRT anode!! Damn, I assumed that since I drained the CRT, everything was good to go. I started to remove the flyback Xformer and zzzzzap! Amazing how fast an arm flinches! That damn CRT kept arcing to no end. I finally used a clip lead to ground to bleed it as I pulled the chassis. Silly me, every now and then I'll get caught off guard. Been a loooong time since I got zapped, but this was a reminder that I'm not immune to it!

It's only a little tickle off a charged CRT - be a MAN!

OK there General... let me attach clip leads to your ear lobes and you tell me how it feels!
Often it seems that any real damage from shocks comes from cuts, scrapes and such when the muscles involuntarily flinch an arm or hand across a circuit board, etc.

You mean when the back of your hand RIPS across the solder side of the board, shredding your skin as it goes!

However, there's no convenient PCB near the final anode connection, so that doesn't apply!.

Worse if the guy stand behind you looking over and saying "what's that do (BONK)" Elbow to his nose

HiTech

Exactly! But don't forget about the internal cabinet framework and such that can scrape/tear skin. This time around, my hand was just above the CRT's neck, next to the aquadag.

When toyed whith a flyback i just used some crocodile clips and they dont have HV wire.Then got too close to one.I first felt a tickle then the insulation on the wire couldnt hold it back anymore and zap.It arced trough the ruber on the wire and on to my hand.Left a very anoying burn on my hand that is was scrathing for like a weak.Oh and the flyback was runing whith a costum driver and so had a lot more power.(Had to give it cooling times becuse it was getting too hot)

For the record to the repliers who are amazed at how high and dangerous 1800VDC is, consider this. Electricity ionizes air on a normal day at usually around 20,000 volts per inch. When you get a shock from rubbing your feet on the carpet and touching a door, say, a quarter of an inch spark, thats 5,000 volts. Not many people die from every-day static electrical shocks. As another note, the stun guns the police use generally are between 150KV-300KV, not 2KV like this (which is why you will see no spark jumping between the electrodes an inch apart).

On a side note, the AC wall outlets in USA homes of 120volts can easily be deadly due to the high current. Anyways, don't just see a number and think its dangerous current+voltage=energy
