What kind of power is available on your cannon? Is it hand held or mounted? I designed a multi-spark high voltage ignition system that uses a pulse generator, IGBT and an automotive coil. Generates 3 rapid 50KV sparks on an automotive spark plug. Never fails. But you have to be able to assemble som...

I will definitely look into that method of metering fuel, never even occured to me to do somethign like that. this is why I like these boards :D

and I definitely understand that gasses need to get vented out, i usuallhy do 2 or 3 shots, and leave the end cap off for a while, and go at it again

ok, this is what I ended up doing... using the ignition coil and disposable camera instructions in the wiki as a guide, I was able to build a circuit that charges the coil, which would probably bridge over a 2in gap, right now I have it gapped to a touch over an inch. I set it up with a "remote" ign...

Or you could dump your fly swatter into an ignition coil. I just tried doing that, and it straight up didn't work, I know my coil is good, makes a OK spark off of a 9v, hooked the circuit up to it, transformer just whined, changed a few things around, nothing. put it back to the way it was, nothing...

in new jersey, I know some people that live in philly, but tasers are illegal there too. and that's why i'm looking to shy away from the bbq ignitors, they do spark, but it's such a puny spark, I didn't use my gun for a few weeks and my electrodes got corroded, the piezo wouldn't jump the gap consis...

i've been using piezo ignitors for a while, but I get mixed results from them, and quite honeslty my hand gets tired from pushing the button in constantly. I'm trying to come up with a coil, you would think that being is I'm a mechanic, a coil would be easier to come up with. if I can't come up with...

need info on ignition system

I have a camping trip coming up this weekend, and I wanted to beef up the ignition system in my combustion cannon before it, I was originally going to do something with the transformer from a plasma ball, but my plasma ball seemingly disappeared a few days ago. I bought an electric fly swatter from ...
