I'm not sure if this actually counts as high voltage, the output is around 360v. I basically took apart a junk-drawer wall-wart
to get the x-former inside, and installed a push-button switch and battery holder. These connected in series with the primary side of the xformer (fewest turns) and used the other coil in the xformer (the part that plugs into the wall) for the output. I wish I had a better case for it besides the flimsy Tupperware container. Here it is.

Basically you hold the two output prongs in one hand so that they arenâ€™t touching each other, and press the momentary button for a shock. :)

Hereâ€™s some pictures in this order: The whole thing, Some insides, The output leads.

**UPDATE**
Ok, so I modified the old one with a buzzer relay like jmartis suggested. It is like 10 fold more powerful, judging bu my little sister's reaction (she tests all my shock-machines, including my large leyden jars.) I'm going to build a capacitor bank out of flash caps that this will plug into if I ever feel like putting black marks on doornobs or vaporizing some Al foil. :)

Here are some pictures and a schematic for anyone who wants to replicate it. :) sorry, STILL no project box. I've gotta get one of those some time...
I would have gotten inside pictures if I hadn't hot-glued everything down first, I can only open it up enough to replace
batteries.:)

**UPDATE II**

Dang! I think I may have burned out the secondary or something.. Oh well. I'm going to radioshack today to pick up some new parts, Including a new xformer to use and a wall-wort for the one my little sister wants me to build. Maybe I'll have enough left over for that project box...

Blah.. new one doesn't even work.. so much for this project...

Haha thats good, you gotta hide it in something though, so that the people don't know they are going to get shocked. I once took a camera flash circuit (minus the cap) and put it in an altoids box, the lid and base were connected to the outputs and there was a mercury tilt switch attached to the lid. So when someone grabs the case and opens it... haha little shock.

Nice one I used to built these things to shock a whole class at my school. Just ask them to hold hands :P

Ha Ha ... that's precisely what I used to do at school forty years ago.

Batteries and small transformers are such fun.

Nice to know that schoolboy pranks haven't changed too much.

hehe, I also made something like this some years ago, for better effect the transformer was driven by a self-oscillating relay

A relay?!? that's a fantastic idea. I have a couple of relays lying around, (old robotics projects), but I'm entirely sure how to wire the dang thing for self-oscillation. :) I wish I had some project boxes laying around, Those cheap o Tupperware containers stink. My folks don;t have enough spare money to go out and get one anyway (at the moment)

My friends and I used to collect grill ignitors and make "tazers" out of them. Now have a camera flash charger in a tic-tac box to shock people with. I never thought to use a wall-wart winding as sort of an iggy coil set up, though...

Heh, I found the idea on instructables.com.

Lots of Camera Tazers, coilguns, capacitor bank chargers, and a bunch of other moderately powerful electrical apparatus. One of these days I'm going to put up an iggy setup how to if someone doesn't beat me too it.

For the relay one, you need a relay thats normally closed (NC) and you wire it so that current flows through the contacts and then through the magnetic coil, so then as soon as current flows it activates the relay and opens it, but then there is no current and it closes again... and so on and so on.

Um, that makes sense but I guess I'll have to find out which pin is which on my relay :P
