Instructables
Picture of How to build a Taser for free!
This is a fun little project you can build! You can give your friends a really powerful electrical shock!

This project should be so easy to build that anybody can build! And best of all, it is free!

Step 1: Get the things!!

Picture of Get the things!!
All you need is...
  • One used disposable camera of any kind. (You can get those used cameras for free at photo developing place like at wal-mart.)
  • Some wires. (I got mine from broken electronic devices)
  • some tape. (I used electrical tape)

And the tools...
  • Flat-head screw driver.
  • Something to strip the wires, wire strippers or a knife.

Step 2: Slaughter the camera!

Now this is going to be a fairly dangerous part, open up the camera and get the circuit out safely without getting shocked by the capacitor...

(The capacitor in the camera is a large black cylinder thing, it is used for making flashes for the camera, but now we are going to use it to shock people!)

First, pry open the camera's case apart with a flat-head screwdriver or just use your hands if you like, but you are more likely to get shocked by the capacitor.
After you taken the camera's case off, discharge the capacitor with a insulated screw driver, and you may get a big loud spark, and after that, the capacitor is discharged... (Use a screwdriver you hate so much, because a fully charged capacitor will leave a scar on the metal part of the screwdriver!)

Great! You had done the dangerous step on this instructable! (Some people say this is the fun part of the instructable because you get a loud spark from the capacitor.)

so why do you discharge the capacitor?

This would kill your friends under the right circumstances if they have a heart condition, also, just get a small pvc joint, get a few more caps, get two feet of stiff copper wire, replace the button with a switch, you get the idea.

This project will build a device that will shock people. If you are thinking of making something that you can carry for self defense, neither the voltage or the amperage on this project is similar to a Tazer. As a result, if you were to use this against an attacker, it would shock them, probably piss them off, but would not incapacitate them like a Tazer would. Just something you might want to know...

what is the amps? could this kill u?
if you havent already figured it out, no it cant. unless you mod it. i have shocked myself many time making and redesigning these..hurts a bit though :)

I bolt one it reley works

Thanks to you, today I learned how to transform an old camera into a weapon. Happy New Year!!!! :-)
it is the funnest part of the entire thing- exept for shocking the crap out of people

i discharged the capacitor with a screw driver, but it recharged after... how do i make it stop recharging? email me @ dogy_woot@hotmail.com thanks

definately the best able of its kind... love it :D 5*

I used super Caps on 22uF and 500v, then i added three more batteries, and the power was enough to make an EMP that was capable of taking out a calculator at 20 feet of range!
does it get discharged if it shocks you biecause it shocked and my arm is num .. but does that mean that its discharged
Probably not fully. It's common sense to try and not shock yourself. If you do get shocked, discharge it again to make sure.

hmmmmm, i took apart some cameras a while ago but they werent disposable(apparently) and i wonder if the round thingies (capacitor?) would work in a simple switch circuit. oh, and it says photo-flashon it

ps, this would make a great prank, just have the wires connect to 2 metal plates on the side and get someone to take a picture for you >:D

does it really work? I don't believe it!!
qmde runningfan3 years ago
Yes, yes it does. I shocked mysellf with one of these cameras beffor
Plasmana (author)  runningfan5 years ago
If you don't believe it, don't make it. And yes it really does work

I really like your instruct able. I just want to make sure that the loud spark won't totally freak me out. Also you copy-pasted the text on this step from Plasmana's version. Yours is easier.

Soooo it shocked me and a pair of scissors...and now it wont work. all the connections seem fine. so idk...any help?
There is a large chance that you destroyed the insulator inside the capacitor by "shorting" it out on your scissors.

oh NOW you tell me it makes a loud spark, i almost had a heart attack. (and i didn't get shocked)
I'm right there with you. I had it right up to my face and damn near shat myself.
when does it make a loud spark
when you discharge the capacitor (if it was charged)
how loud?
It won't scare you if you expect it.
i was afraid to discharge it the first time i made one and yes it freaked me out, it made my ears ring.

Quite simple, I like it...

Make your friends flash!

I shocked myself by accident... and does hurt

when you say discharge what do you mean?
fire
what do i do it? as in cut a wire or what
you discharge the capacitor by putting the metal part of a screwdriver, pliers, scissors or any other metal object that will touch both leads

(the wires coming out of the big round thing that has a stripe with - signs on it, it usually says something like such-and-such-a-number-uF)

of the capacitor, they say you should get something with a handle so it doesn't shock you but I don't think it matters
yea thats about right

I dare any of you to ask for a camera and use a technique like this

to "spy" on people,
Wal-Mart didn't ask for how many, they just said, here's two. Where else can you get them?
i don't know anyone named wal-mart :-)
