Well lol, even if it wasnt ruined when i took off the capacitor, it is now cuz my solder gun is extremely old and it doesnt really have a tip, its like a loop so that killed the circuit... its really no big deal they are only 4 dollars. But as for the smoke and stuff, what happened is i put in the battery and the second i put it in i saw smoke coming from what appeared to be the bottom of the circuit board so i turned it over and saw smoke either rising from the bottom or right underneath the capacitor, but it was gone to fast for me to even check. Also, i used the battery that came with it and there was no metal touching it, i was holding it in my hand so i know for a fact there was nothing. The only possible thing it could have been was me putting the battery in backwards, but i dont even know if that would do it. And as for putting it in backwards i had no clue which way lol so i guessed... i still dont even know which way haha.

And also i was wondering if you could give me a quick explanation of hooking things up in series, or just a link would be fine.

i wonder if polarity matters?????? i have gone through lots of camera circuits, and all of the ones that smoked, the smoke came out from under the capacitor. amazingly even after the smoke, one of them still worked!!! i think it would be the transistor that smoked. did you have the soldering iron across the capacitor leads when it was going? those camera circuits are very fiddly

oh, abut the series and parallel, here is a good explanation http://en.wikipedia.org/wiki/Series_...allel_circuits
just think of the resistors as 9 volt batteries or something.

actually lol... it was really hard to use the soldering iron because it was so big and i was trying to unsolder something so small... i pretty much had to kill the whole top left of the circuit board until i could get it lol. and since im new to soldering and unsoldering it was more of a practice than a doing.

Thx for the link.

Ok i looked at the link and it gave a perfect explanation.

"As an example, consider a very simple circuit consisting of two lightbulbs and one 9 V battery. If a wire joins the battery to one bulb, to the next bulb, then back to the battery, in one continuous loop, the bulbs are said to be in series. If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel."

That makes sense in itself, but i am still wondering as to how you would set up batteries in a series, would u like connect the positive to negative? and then have a wire or whatever coming from a positive from one and a negative from the other?... i feel bad about taking your time to answer such trivial question, but i promise you once i learn something i wont forget it.

well i would think that you probably made a solder bridge between some of the components, causing the transistor to fry. i think that once the smoke comes out, the circuit or component is bad. if you really want to continue this project, you might have to get another camera flash circuit , i think if you asked a place that does processing of film for camera's, they might give you a couple free! sorry to tell you that if you do get another circuit, pull it straight out of the camera, and hook it up to a battery, short the two switch terminals together, and the thing should still flash. if it does, just solder 2 wires to the capacitors leads and you should be right. sorry about that.

Oh... i only tried to unsolder the capacitor after whatever it was fried... the circuit was already dead, thats why i didnt care lol... and also, i edited my comment above your last one, so if you could plz read it, i still have a question about putting batteries in a series.

i am making up a diagram for the wiring now, i'll post it in a couple of minutes

here is how to wire up the 9 volt batteries, with this setup, you will get 36 volts out, but at the current one battery can supply. you can do this with other batteries too, but don't connect up too many, as the batteries cannot take much stress. Heres my crappy drawing using microsoft word battseries.PNG

i saw a video on youtube, where someguy wired up 100 or so 9v batteries, and got some pretty big arcs, but after about 3 seconds of arcing, a battery exploded!!! i am pretty sure if you hooked up 100 9v batteries, it would be lethal

dude thats sick lol...but instead of putting wires from one another couldnt you just attach them together going positive to negative like stick them together? so it would be kinda like they were stacked on one another 2 high and 2 across? i know this is a confusing explanation but it seems like it would work. and thx a lot for the drawing.

yeah, you can just clip them together, that's what the guy on youtube did. i just couldn't draw them like that on word though

Thats tight, thx a lot for the explanation, i guess i just need to wait and get another disposable camera. and to bad that there is no way to put pictures in your signature. And also, do you know of any good devices to get decent transformers from? I like the idea of making a fun stun gun out of a disposable camera but i still think 9 volts and transformers are the best way to go as far as shock boxes are concerned... until i learn how to make my own circuits which i cant see happening very soon.

the vid i was talking about, if you haven't already seen it. i don't want to touch that!!!!!!http://youtube.com/watch?v=HAHxo4cRk-E

oh, i must have posted the same time as you. do you discharge the capacitor into the transformer, and get a higher voltage out?
