do disposable camera's run out of battery? Answered

 I've recently made a taser out of a disposable camera and was wondering does the camera run out of charge over time? or does the charge get less or something?


So... What you want to know is whether or not the battery in a cheap disposable camera lasts forever?

No. No, they don't.

No need to be rude. It's a reasonable question if you don't know much at all about electronics of any type and are confused how a disposable camera even works.

Answer is yes btw - the batteries do run out. ;)

Hmm... I was going for "mildly sardonic". If I came across as rude, I apologize.
I do, however, believe that it may be expected that during the process of disassembling a camera and reworking it into a "taser", a person might have noticed that the battery in the device is just a regular AA, and not a magickal, self-recharging perpetual battery.
But I could be wrong about that. ;-)

i thought that the camera was run by the battery on the circuit board
the one that you wrap the wires around?
surely a AA cant give out 330 volts?

The thing you attached the wires to is a capacitor. It's kind of like a battery, in that it is used to store an electric charge, but it actually gets its charge from the AA. Most of the rest of the circuitry in the camera is used to transform the 1.5V from the AA into a higher voltage to charge the capacitor up. The high-pitched "charging" noise that the camera makes is caused by the circuitry that boosts the voltage.
The should also be a second transformer circuit on the board, which is used to boost the 330V from the capacitor to more than 1000V, which is what it takes to fire the flash bulb. In theory, you could run a second set of wires off of the flash leads and then use the camera's flash button to deliver a shock of anywhere from 1000V - 4000V, depending on the camera's circuitry. I don't recommend doing this, I just mention it to illustrate that a AA is more than capable of generating much higher voltage, given the right circuitry to help it out.

thats mad!
i never new that you could do it. thanks :)
sorry for doubting you haha
so your saying that in theory if you just cut the wires leading into the flash and hit them together or something and pressed the camera button while it was charged it would be more than 1000 volts?? or have i got that completely wrong?
and also i sold mine to my friend and was trying to make a new one i think the camera is a koadak and it keeps on charging itself. Is there any way to stop this?
also ive made you my best answer :) or im about to anyway

Nope, that's exactly it. The charge coming directly out of the capacitor (like you have it set up now) will be 330V and will activate anytime anything touches the wires and completes the circuit. Moving the wires to the flash leads (instead of the flash bulb) would output 1000V+ to the wires, but you'd have to push the camera button to make it work.
As for the charging, isn't there a button or lever or switch on the camera that you activate to charge the flash? Most of them that I've seen have something like that, so you should just be able to turn it off, I would think. If not, you could add a small switch in the wire coming off the AA, or just remove the battery to keep it from charging.
Thanks for the Best Answer, by the way.

thats pretty huge
i tried doing that with the flash but there are three wires? two coming out pretty much out of the battery and the other comes out of some kind of plastic thing which i'm guessing makes the charge bigger? i was wondering which wires would be needed to shock something? or how they would be needed to be set up?
just so you know i do not intend to shock anyone with this. I haven't even shocked anyone more than half charge with the one i sold.
I just want to do it to see what kind of damage it can do to metal

I worked at a photo lab where all the flashlights were run on disposable camera AA batteries.

no they dnt last forever, i made a camera taser an the batterys last for a good amount of time.
when they do eventually run out you can just put another one in. they use AA

also...take them out if ur mot using it because mine shocked me cause i left it in

My brother in law owns a photo-developing shop.

When he gets disposables in, he pops out the batteries (AAs) and keeps them to use in his own gear.  They don't last as long as top-spec batteries, but they do last a lot longer than they need to for the camera.

A disposable uses a normal battery - Usually there's one or two AAs or AAAs in there somewhere although if they're inbuilt they will have less then normal capacity (hence cheaper).  In normal use the film will run out well before the  battery.
It would be easy enough to replace them, or try putting another in series to up the output voltage.
