How to build a taser for free

Step 4Have fun

Have fun
Test your new taser one something/someone by touching it/them with both capacitor contacts.

Most capacitors are charged from 300 to 360 volts with very low amps (didn't even register on my multimeter) so you dont need to worry about hurting anyone too bad (I've been shocked quite a few times).

If you want, you can even take out the capacitor and solder wires in its place. The voltage stays the same and the shock is constant (as opposed to the quick discharge of the capacitor), but it doesn't hurt quite as bad. I think the trade is worth it. It will still make your arm twitch pretty good.

I havn't tried it yet. Though it would obviously work, I havn't been able to find a ***FREE*** disposable camera.

Buy a compacitor form radio shack instead.

a while back you said u couldn't find any free camera's, i went to walgreens, and asked for disposible camera's with no film, or that they took the film out of , just say your going to recycle them, and u can get some, i got 18 free with my first try, go about once a week, although i had 18, only 5 actually worked for making tasers with, and only the kodak ones, but if you press the flash button before u even open it, and hear it charge, that's a good idea that it will work. just dont take forever soddering something, because it messes up the board, and all it will be good for then is getting the battery out. :-) cheers!

Haha if you dont want it to spark you can use your finger.
Jul 25, 2007. 12:57 AMryan289 says:
u can make these without even taking them apart
Feb 16, 2012. 4:48 PMAron313 says:
Make an instructable on it!
Jul 27, 2008. 12:15 AMhellstudios says:
ummm.....HOW?
Jul 30, 2008. 10:25 PMryan289 says:
i use to do it all the time let me experiment and see if i can remember
Sep 2, 2008. 4:27 PMtubbychick3n says:
are you talking about just breaking the flash bulb out and soldering wires onto those contacts? because a few comments up, someone was talking about that.
Sep 4, 2008. 7:54 PMryan289 says:
no when u take the paper off of it there are 2 holes on the bottom and i know you stick a paper clip in each one
Dec 20, 2010. 1:58 AMhyunwoolim says:
man that is soooo cooool an electric camera! i should add that on my prank list.
Jul 15, 2011. 11:29 AMsuperduperdrew says:
so it's a bad idea...
Jul 15, 2011. 11:29 AMsuperduperdrew says:
dude, those really hurt...
Sep 5, 2008. 6:38 PMtubbychick3n says:
oh, well i guess that works too.
Sep 11, 2010. 11:48 AMTobor 2.0 says:
your kidding me right. I disabled a dis. camera with the same data board to make an E.M.P. generator and i got shocked by it. it didn't hurt at all!

Buy a bigger compacitor for radio shack!

an e.m.p you say? you can make small range ones with capacitors and coils of wire. but true e.m.p's with any range require a large amount of capacitance, at a high voltage, and call for a coil to be suspended inside a metal tube. then at the moment of discharging the charge through the coil an explosion must take place. at one end of the tube. thrusting the coil down on the tube one turn at a time in rapid succession, creating a short circuit and forcing the magnetic wave of energy into a smaller and smaller space. compressing it. until the last coil touches and it explodes from said device carrying a large amount of energy and covering a fair distance. transferring its energy magnetically to wires and components in electronical devices (most of them are shielded so any real damage would take a lot of energy) causing voltages that are too high and currents to flow wrong ways. destroying said devices :3 you might be able to get it to knock out those little pocket games you can get at target though :D

I didn't say it worked I was prototyping an E.M.P., honestly people stop jumping to conclusions
Jan 14, 2012. 9:05 AMToddisI says:
i think ill just go to radio shack and buy a compacitor... and a double A holder
Feb 16, 2012. 4:46 PMAron313 says:
Haha thats what i did!
Aug 14, 2011. 8:10 PMBen Mighall says:
How do you increase the power of this?
Sep 28, 2011. 5:30 AMtswannell says:
im a bit late but all u do is get a bigger capacitor the long brown thing that looks like a mini battery and u might need a bigger battery but be warned dont go anything doubled the size cause u will put holes in meta we put a hole clear through a blade on scissors
May 24, 2011. 6:04 AMadamnsmith says:
where can you get a "FREE(=" disposable camera i cant find any
Jul 14, 2011. 4:14 PMO_Kodama says:
Walgreens could work, in the past I used Walmart to get what I needed just by going to the camera section and asking for the used disposable cameras. This only worked for me at one store, the rest of the locations told me I couldn't have them. Good luck!

your so annoying
Jul 1, 2011. 9:33 AMcharchar97 says:
i think that you can ask around at like walgreens and places like that unno
May 5, 2011. 4:26 PMghayden says:
can i take the flash out of the circuit an it still work i'v rigged it up to 2 1.5 volt battieries an its well good
Apr 27, 2011. 10:10 PMrvýdy says:
Don't they just have, like, a simple circuit of it? It would rather be convenient that way.
Apr 11, 2010. 7:15 PMmikmkt93 says:
You can make both tasers with one camera. just make the second one with the wires, then use that to charge the capacitor and u can use the capacitor for a fast, very painful taser, and the charger for a less powerful, but steadilly shocking taser.
Jan 7, 2010. 11:24 PMdume says:
omg it is like the crazyest thing but i chage it and no mater wat it just shocked me where evere
Jan 14, 2008. 4:31 PMBuster108 says:
Hey i made couple of these for igniter,anti-sister room gurdian r/c,and couple other cool stuff nut i never happened to try to shock some one i solder wires to the bulb cotacts and rip out the bulb..will that increase the volts or amps?and i read that it knoked out some1 so im not sure if its wont rely do something bad to whoever i shocked some1 tell me plz,and what vots and amps does it discharge since i dont have a voltometer..and when i rip the bulb out and solder wires to contacts the swich doesnt work and it doesnt charge up with the wires conected so i have to charge it up ten conect the wires(or put them onto skin)to get a discharge...... tanx in advance
Jul 27, 2008. 12:13 AMhellstudios says:
no, this type of thing cant make someone pass out... i modded an operation game with one of these and had someone play it...then i watched the sparks fly :D
May 15, 2009. 1:04 PMTyMan210 says:
I should try that! You lose! *ZAP!*
Jan 29, 2009. 6:41 PMmessmaker says:
that doesnt just give u a tingle that thing is deadly. i tried it on my mate and he was on the floor for 5 minutes. like his joints were soldered together.dont try this on ur self. it is seriously deadly with a 1.5v battery (AA) 9v battery... screw that myspace.com/timmywazere
Jan 22, 2009. 9:57 AMbabbs1st says:
make a bank of capacitors maybe even more powerfull i don't know
Aug 17, 2008. 5:00 PMRGM La Paz says:
what type of capaciter
Dec 22, 2008. 9:29 PMawang8 says:
330v, the ones found in flash cameras to power the xenon tube.
Nov 1, 2008. 9:16 AMnicklowry says:
hey, how do you discharge this thing
