it will end up bulky, expensive, and dangerous if u choose to make one...
but...
there are ways
1st- car ignition coil... i dont know if 12v is needed
2nd- flyback transformer... get it from a tv or pc monitor

those 2 are almost the same thing...

The way I made myne was pretty simple. I wouldnt do it though. Through building it I did get shocked and it hurt sooooooooo much. Basically I got my old handheld stroblight and wired it up to make a spark. It took about 3 minutes and produces a nice 1.5"-2" spark. Ive made modifications to the switch which took a while but its still really easy. Also you can make a small spark from an old disposable camera. The spark is brilliant for small cannons but awfull for quite big ones. The spark it produces is A; fairly weak and B; it is quite a cold spark which makes it hard to ignite fuel. If you wanna build the camera one which is really cool just go to http://www.i-hacked.com/content/view/181/48/. Good luck by the way be carefull the strobe ones can knock you out and if you have a weak heart (loads of people do and dont even know about it) It can kill you.

the car coil does need 12 volt DC to charge, the converted charge comes out of spark plug wire is normaly upwards of 25,000 volts DC, the newer one of course have gotten stronger, the stun gun igniters are byfar the best i've seen so far, for the work they do for there size is well worth the mild investment and work to set it up, (machinicly speaking), take a poll on this subject
