I'm currently using a BBQ grill sparker for my cannon, but I was wondering if an assembly using, say, a nine-volt battery (or whatever's required) and a momentary switch would still generate a viable ignition spark.

The thought occurred to me because it's rather hard to place the BBQ igniter anywhere, and momentary switch could be housed inside a project box from Radio Shack along with the controls for my chamber fan.

Well, remember that it requires roughly 12,000Volts/inch to make a spark. Thus, your 9 V battery is capable of producing a .00075" spark.

Pretty pathetic, no?
It is possible to use more advanced electronics to give you high voltage sparks, but I don't know enough about them to help you... and you'd probably need essive help if this befuddles you.

trh making a stun gun, theres plenty of plans on the net. or just get a whole bunch of capacitors and use them for each go

Okay.... I'll just abandon that plan for now. That is, until I get my commission into the FBI when I can get all the stun guns I want!

Hey if you have a strobe light (handheld is what I used) you can wire those up in a way to make a spark about an inch to two inches, depending on what kind of strobe you use. I will post plans soon. I just need to take some pics!
