Introduction: How to Build a Taser for Free!

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!


Disclaimer: This instructable involves modifying a device that operates on 300v. Use this modified device for educational and self-defense only, using this modified device on other people may results an serious injury or even kill other people. I am NOT responsible for any of actions using this modified devise, the responsibility is yours...
So be careful what you are doing, be safe and have fun!

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.)

Step 3: Modification Time...

Picture of Modification Time...

The modification is very simple. Strip off 1/2 inch of insulation that on the wires and just wrap the two bare ends of the wires around the leads of the capacitor and tape it down so it won't come off and your almost done!

Step 4: Putting It Back Together...

Picture of Putting It Back Together...

After you had modified the camera, it is now time to put it back together!
Put the circuit board back into the camera's frame and put the camera's cases back on too, and make sure the two wire are sticking out on one end of the camera.
And don't forget to put the battery back in too!

Step 5: A Little Bit More to Go...

Picture of A Little Bit More to Go...

Okay, this is the last step, strip off another 1 inch of insulation off the wires and tape it down, but make sure the bare parts of the wire is exposed!

And...

Step 6: Enjoy!

Picture of Enjoy!

You are done!
The tazer gives out about 330 shocking volts!
Okay, you can go shocking your friends or use it for educational and self-defense...

Also, I am not responsible for losing your friends after shocking them!

Have fun!

so why do you discharge the capacitor?

austech (author)2013-06-30

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.

ptbeast (author)2013-05-26

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...

tesla man (author)2012-02-29

what is the amps? could this kill u?

PyroTrician95 (author)tesla man2012-08-03

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 :)

book54321 (author)2012-05-18

I bolt one it reley works

M.C. Langer (author)2011-12-31

Thanks to you, today I learned how to transform an old camera into a weapon. Happy New Year!!!! :-)

somebody12345 (author)2011-12-22

it is the funnest part of the entire thing- exept for shocking the crap out of people

rub3n (author)2011-12-10

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

FrozenIce (author)2011-11-26

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

ugv7821 (author)2011-08-21

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!

russian lumpy (author)2011-08-12

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.

xinistrom (author)2011-08-15

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

runningfan (author)2009-05-26

does it really work? I don't believe it!!

qmde (author)runningfan2011-08-14

Yes, yes it does. I shocked mysellf with one of these cameras beffor

Plasmana (author)runningfan2009-05-26

If you don't believe it, don't make it. And yes it really does work

Nico N. (author)2011-08-04

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.

kuratano (author)2011-06-08

Soooo it shocked me and a pair of scissors...and now it wont work. all the connections seem fine. so idk...any help?

jadams16 (author)kuratano2011-08-03

There is a large chance that you destroyed the insulator inside the capacitor by "shorting" it out on your scissors.

bloke2022 (author)2009-08-17

oh NOW you tell me it makes a loud spark, i almost had a heart attack. (and i didn't get shocked)

Alienwax (author)bloke20222011-07-30

I'm right there with you. I had it right up to my face and damn near shat myself.

sharlston (author)bloke20222009-10-07

when does it make a loud spark

bloke2022 (author)sharlston2009-10-07

when you discharge the capacitor (if it was charged)

sharlston (author)bloke20222009-10-07

how loud?

bloke2022 (author)sharlston2009-10-08

It won't scare you if you expect it.

bears0 (author)bloke20222011-02-18

i was afraid to discharge it the first time i made one and yes it freaked me out, it made my ears ring.

chuerta1 (author)2011-06-28

"Also, I am not responsible for losing your friends after shocking them!" LoL!

xintus (author)2011-06-24

Quite simple, I like it...

jsmit1 (author)2011-06-20

Make your friends flash!

webtelles (author)2011-03-06

I shocked myself by accident... and does hurt

nunchucker (author)2010-11-30

when you say discharge what do you mean?

hazza the gun (author)nunchucker2010-12-04

fire

nunchucker (author)hazza the gun2010-12-10

what do i do it? as in cut a wire or what

bears0 (author)nunchucker2011-02-18

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

hazza the gun (author)bears02011-02-19

yea thats about right

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

http://www.youtube.com/watch?v=klaVyjCjoUw

to "spy" on people,

tinstructable (author)2010-07-10

Wal-Mart didn't ask for how many, they just said, here's two. Where else can you get them?

bears0 (author)tinstructable2011-02-18

i don't know anyone named wal-mart :-)

Here are some tips on getting free used disposable cameras.
  • Ask nicely.If you walk up to the counter and say,Hey,give me some used disposable cameras,their not going to give you any.
  • Be polite.Something like,Can I please have some used disposable cameras for a project, is almost guaranteed to get some cameras.
  • Don't be greedy.If they ask,"how many do you want"don't ask for 20 or 30."Ten or so" usually suffices.
  • If they ask you what you want them for,
"for a project" does nicely.
Always say thank you.That is guaranteed to get you cameras the next time you come.
Plasmana (author)bylerfamily2009-05-24

lol, then I guess I am a bit greedy. Cos I ask for about 20 or so, they are first surprised about how many cameras I need, then I say "I am working on a big school project". And then they give me the cameras :-)

bylerfamily (author)Plasmana2009-05-25

I am home schooled so I can't say that:(

bears0 (author)bylerfamily2011-02-18

i'm home schooled too, it is SO much better than public school.

Plasmana (author)bylerfamily2009-05-25

Huh? I am home schooled as well and I say it anyway, lol.

Mercurion925 (author)Plasmana2010-04-02

 I'm was home schooled as well... maybe I'll try this next time I go to the photo store

bylerfamily (author)Plasmana2009-05-26

What do you say during the summer?
I've got you now...

Plasmana (author)bylerfamily2009-05-27

Idk what you are talking about...?

bylerfamily (author)Plasmana2009-05-28

You can't do a school project during the summer.Oh,yesterday I got 21 cameras when the lady asked me how many I wanted I said "it doesn't matter,just put a bunch in the bag."I got 21 cameras!.
But 2 of them weren't flash cameras...

Plasmana (author)bylerfamily2009-05-29

lol And yeah, I got some non-flash cameras too...
