or you could just charge up a high voltage cap and have something go across the two terminals.
why should we have to draw you a diagram if you are incapable of buying a disposable camera, that costs like 5 dollars?
also, you're thinking too hard. igniting fuel? all you need is literally a xmas tree bulb and a 9v battery. you can add fancy shit like i did such as the safety of a parallel circut with both a SPST switch and a PBNO switch. i could draw you a diagram of THAT just because its also capable of igniting low order explosives. BUT you really wouldnt need a diagram if you had the capability of reading it you would already have the knowledge to be able to do it. if that makes sense.
this is the most simple device ever and takes like 5 minutes to solder. you might need to click on the pic to see well. and i didnt really take much time doing this cause i dont really care so i guess it could be wrong
