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

Parts:

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

Optional:

- 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.

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

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.

how would i do this without a capacitor

just use the solder wires to the circuit

You can't, the capacitor is the component stepping up the voltage.

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

author

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

author

even without the stored voltage it still stings. i found out....

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

author

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

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

1.5 Volts or even 9 Volts aren't going to hurt you. In fact, electricity wont even flow through you! You can get some sparks from touching it on metal, but it is completely harmless.

The capacitor can actually stop your heart

author
ash.springer.9 made it! (author)ash.springer.92015-03-31

he was being ignorant to how it works because of the 1.5v battery that you put inside and assuming if you plug in a bigger battery it will be more powerful when in reality anyone who knows, knows that it isnt 1.5v thats being discharged and that the battery alone couldnt do it

assuming this is a say 300v flash cap do we know a lethal level ? im curious i want a taser but if i throw the wrong cap into the circuit it could go very wrong or right depending if i like a life sentance

You could get a 500-million volt taser with no amps and live. You could also get a 12v one (like a car battery) and 300 amps and die. Amps are all that matter. Yes they are related, but all you need to know is how many volts (volts create sting/pain) and how many amps (amps create death, and even just 1 milliamp, so 0.1 amp could be lethal) when dealing with tasers.

author
KoliD made it! (author)KoliD2015-04-23

It isn't the voltage that you necessarily have to worry about. What makes an electrical device potentially deadly isn't the voltage but the current. Now, considering the two are proportionally linked through Ohm's law (V=IR) there seemingly is a correspondence between voltage and lethality, but there is no standard set voltage that's considered safe (at least none that I know of). However, if you are to consider current, as few as 100 milliAmps of current are enough to kill you if they pass through your heart (ie: you stun someone right in the chest). So if you have the taser set at a specific voltage, the actual current can vary depending on what the resistance is (which can vary due to environmental factors like moistness of the skin and distance between probes, and so on). All and all, I'd recommend doing a little research into electrical theory before attempting something like this. I would also recommend not trying it out on someone that isn't a threat to you, and certainly not yourself, but I suppose that's just me.

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!

its ridiculously easy, literally attach 2 wires to the capacitor leads then touch those 2 wires on metal or skin and it will do the same thing

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.

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
