Hmmm... the possibilities... lol... hey, where did you get your flyback from? and why are they called that anyways? and just to get this straight... tomorrow im gonna go ahead and try my idea on the switch to charge the capacitors, but i am also going to have a switch to release them, so to do this i need another switch which i have and all i need to do is attach two wires to each capacitor (one on both side +,-) and have both from one side running to whatever i am going to have people touch to get shocked and then i will have the other two going to the push button switch both on one prong... and then have a wire from the other prong going to the other bar or whatever that they need to touch correct? Which leads me too a couple more questions...

1. Will it be safe for someone to have a bar in each hand and have the charge go through the body with one capacitor? and how about two?

2. And i am assuming it would be safe to have both charge go in one hand so it does not go through the body, but i just want to ask anyways.

i got my flyback from a computer monitor, you can get them from anything with a crt tube. one capacitor should be alright, but i'd start to worry after that they are called a flyback because the thing operates by the voltage flying back to switch it off. if you mean just through the hand, it should be right. got to go to bed now, school tommorow see ya later

ya... two would probably be to strong lol, but for those crazy people i will just put it in there with an on/off switch. hey Thx for all your help again and tomorrow when you get on I will probably have a lot more questions for you lol.

If you don't use a current-limiting resistor in series with the capacitor and one of the prods, then your shock might kill somebody or cause something to catch on fire.

yeah, that's why i said to not shock people, where the shock has to go throught the heart. And only add 1 more capacitor if it doesn't hurt much, any more and you'd probably be in danger

Yeah its cool... I wont do anything stupid. I also have a resistor to, so I could throw that on there.

You need to be careful with how you apply a device like this, they charge to about 300 volts even from a 1.5V battery and if you add too much capacitance you could easily make something that could kill someone, or start fires. I'm not sure why you say it doesn't have enough 'kick' I've taken a standard camera flash out of a disposable camera and accidentally touched the board when it was discharged and the capacitor still had enough voltage to make me drop it. (The flash tubes require a couple hundred volts to conduct, the cap will recharge to 50 or more volts due to dielectric absorption)

An ordinary little resistor has a max voltage rating of only 200V to 250V. It will arc from the high voltage. When it arcs then it is just a piece of wire and is not limiting the current.
So use a high voltage resistor or a few same value resistors in series to limit the current.

Haha Sceadwian I never said it didn't have enough kick, it probably does. I was just saying 'what if' I didn't think it was strong enough. At this moment I am kind of scared to purposely shock myself with it, but I accidentally did and it didn't seem that bad. The thing is it all happened so quickly I could hardly remember what it felt like. And like I said, if I did add another one on it would be with a switch so I could turn it on or off.

so i gather you got it working?? congrats!!! a switch on the second capacitor is a great idea!!! just make sure the switch itself isn't connected to the caps, then when you go to change it, you will get shocked through the switch

Well, I almost have it all working, I have kinda delayed putting it all together until I find a suitable case to put everything in. But what do you mean don't connect the switch directly to the capacitor's? What do you mean "directly"? And also, an automotive flip switch would work right? I can't see why it wouldn't.

just don't let the connections touch the case of the switch (if it's metal), or you will get shocked when you go to change between 1 and 2 capacitors. yep, an automotive switch should work, but if it's case is made of metal, be careful, like i said above

Oh ok, I had a feeling that is what you meant, the case if all plastic though. I want to find a suitable project box type thing around here to use, but I can't seem to find one, they are all to big or to small. I could always buy a project box from radio shack but if I can I would rather not spend the money. It's cool though, something should show up.

Hey, I was also wondering if you had aim or msn messenger or something.

Yeah definitely be careful with high voltages,even if the amperage is not that high.I can't remember what the amperage is that would hurt or kill a person by stopping the natural electrical conduction of the heart,but you don't want to find out.Case in point,being a Paramedic I got dispatched to a guy who got "Hit" by a lawnmower Magneto while "Testing" for spark.He had a congenital condition called WPW(Wolff Parkinson White)Google it if you want to know more about it.Anyway,the relative small shock was enough to trigger the WPW in his heart,and made some havoc on the EKG monitor.After some medications from us we fixed him,he was ok.Point is he was lucky,but you never know what stray electricity will do to the hearts conduction system,just be careful....:-)

i do have msn, but i don't go on it very often (forum browsing) . is the switch plastic?
