MAKE Flickr photo pool member Rob Cruickshank made an awesome miniature electric chair, the video is hilarious! He writes – “Putting the “cute” in “electrocute”! Powered by a 9v battery, it delivers just a little jolt. Endless possibilities for fun- imagine if the one who loses at Scrabble, or doesn’t do the dishes has to go to “the chair”! Also good for trick-or-treaters who show up without a costume. “ – Link.

Do be careful with this little fellow, some medical conditions do not respond well to electric shock. A 9-volt battery can pack more wallop than you may expect.

Quite right! I actually thought this up in response to a project previously posted on MAKE, which used a disposable camera flash as a shocker. I felt that one was incredibly dangerous, then started thinking of a project that would deliver a shock, but not have the potential of actually killing someone. The design of having it give the shock across two fingers of the same hand is deliberate- you should never, ever, make something to give a shock across both hands, as the current then has a path through the heart. And obviously, this is not a good prank to play on your 90 year old uncle, unless you stand to inherit something when he dies.

Ah, a fine tribute to the significant others of makers and the crap they put up with

My favorite part of this is that the wires are coiled!

Yeah, you can also make a mini-taser with a relay like that. Can pack quite a [little] punch when touched to the creases of your palm!

ok.. I made this with radioshack 9vdc relay (#275-005) as suggested but It does not make a constant buzzing sound when it is switched on..I just get a click sound as switch goes on and off and only get a shock at that time not when switch is on ON position all time.. I’ve checked all connections.. any help.. appreciated.. Thanks.
