Picture of Stun Gun
first you must find a disposable camera. I think I used one with the brand name kodak. the reason this works is because of a component in the camera called capacitor. this component is charged, holds its charge, and then will quickly discharge. this of course is useful for the flash in the camera, so do not buy a camera without a flash. (I was originally going to make a flash bang by rewiring the shudders and flash, and by upping the voltage on the battery, but bought the wrong kind of camera, and got the idea for this after shocking my self while messing around with the circuitry. being shocked with this hurts, and it is dangerous so please be responsible and do not use this on animals people or flammable items.

I recently remade one of these with four of the capacitors in parallel. Got some amazing sparks with a deafening crack. here's a video:

Step 1: Remove the cover from the camera

this step is very easy. you just remove the cardboard/ paper from the camera and pry open the two plastic pieces that make the housing for the camera. do not throw them away though, I ended up using them for the housing of the stun gun although you could buy a project box from Radio Shack and it would probably work better.

Step 2: Remove the mechanics and plastic from the camera

to take the picture many disposable cameras have a series of gears that must be turned in order to prepare the camera to connect two leads. all of these are useless and need to be removed. the lens and view finder will also have to be removed.

once while taking one of these cameras apart my finger touched the capacitor and it knocked me on the ground and momentarily paralyzed me.

The shocks from these can be pretty painful (I have experienced it myself), but I have never heard of any of them having enough power to do that. Do you remember the specs on the capacitor? I am curious to know them.
no sorry, but I do remember the box saying somthing about "super flash."
hope this helps.

Is this thing practical for self defense?
Higgs Boson (author)  ilpug3 years ago
probably but I wouldn't count on it, because you would need to wait for the flash to charge, and although it does have a high voltage it doesn't have a high voltage compared to a real stun gut. I don't know how much current it has, so I wouldn't use it on anybody. Not to mention I have only discharged it into metallic objects. I don't know what would happen if you shocked a person with it.
Well, hook it up to a multimeter. Measure both the amperage and the voltage.

If it rates at High voltage with low amperage, then it is probably safe for defense use.


Ask an expert.

I need to make another. I busted my first one. besides I don't have a multimeter. I am pretty confident that it is safe, but still do not ever use it on anything that is alive (or flammable).
You've built the things you've built without a multimeter?????
You're amazing.
Well, get a multimeter!

If I make this, I will for sure test the volts/amps and post it here, but I can't promise anything.

too bad you broke the original

I cant help but wonder if you could make one out of an electric flyswatter. And i also heard that 330v doesn't hurt all that much.
Higgs Boson (author)  freeza363 years ago
Maybe not but would you want to get shocked with three times the total output of a wall outlet?
made something like this about 6 to 7 years back but used the flash off of an old and what used to be expensive camera reusable had it rigged to only charge the capacitor when i was ready and used the 9 volt batter connectors and attached the outputs to those so you did not have to worry about loose wires and it would gouge out metal. been thinking about making another one.

seeing that nickle... i wonder if 2-3 parrallel units could do some battery tab spot welding... hmm
Higgs Boson (author)  ironsmiter3 years ago
Yeah the capacitor had a capacity of 330v so with a few parallel units would do some damage.
