How to Build a Taser for Free




Introduction: How to Build a Taser for Free

This is a very easy, very fast and not to mention FREE way to build a "taser".

Step 1: Parts


- Disposable Camera - You can get a free*, used disposable camera anywhere film is developed


- Soldering Iron
- Copper wire
- Electrical tape

*I've gotten all of mine for free, but I've heard of other people spending up to a quarter for each camera.

Step 2: Take It Apart

Tear the camera apart. Don't worry about breaking it (it was free!!), all you need is the circuit.

Step 3: Charge It Up

Stick the battery from the camera in the back of the circuit (Get the polarity right). You might want to use electrical tape to secure it because it tends to fall out.

Then hold the button for a few seconds. You should hear a high-pitched whine. When the whine stops your capacitor is charged.

Stay clear of all the metal parts when the battery is in, or when it is charged. You might even want to electrical tape over all but the capacitor contacts.

Step 4: 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.

    You zapped yourself and surely was painful, but did it knock you down like the real deal or just caused lots of pain while still capable of standing up?

    can it kill someone or harm if i remove the capacitor and use the voltage from transformer (the constant current)

    where is the button that charges it????????????

    OK, Let's build it...

    Plzz reply fast

    How can I do this without a camera but I have the capacitor

    I tased myself (accidentally) 4 times, and i'm a pretty little guy, so unless your tasing small children I think it's somewhat safe.

    I'm pretty sure that is the transformer because without the capacitor it still ups voltage.

    Yes, but the capacitor stores all of that voltage from the transformer and releases it very quickly, making the shock.

    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

    what size capacitor did you use to punch through a scissors blade. sounds fun

    i think ill just go to radio shack and buy a compacitor... and a double A holder

    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
