OK, I need a bit of help here. Ive been looking for plans on the net to build myself some kind of stun-gun to use as an ignition source for my next cannon. My next cannon will necessitate ignition every second or less for up to an interval of probably never more than a minute or two.

This is of course for my newest design project, a Gatling Combustion Cannon. The only things holding my back as of right now is getting an ignition source figured out and I haven't finalized the loading concept yet, I'm thinking 2" diameter, 4" long pykrete slugs as uniform ammunition.

Any links to schematics or ideas would be welcomed.

By the way the reason I'm not buying one online is because there illegal here in Canada so the Internet is not an option.

Easiest way to do this is;

1. Just build an automotive igntion system. Points, rotor, 12V battery and an automotive ignition coil. The points+rotor could be an integral part of the Gatling mechanism. (You can also use the 12V power to run the Gatling's motor.)

2. Replace the points+rotor with a 555 timer and a high power transistor.

3. Buy a <strike>stungun</strike> high voltage power supply off <strike>ebay</strike> BCARMS and modify it a bit. Most <strike>stunguns</strike> high voltage power supplies spark at a few tens of hertz (that's a few tens of sparks per second). A little fiddling with the <strike>stungun</strike> high voltage power supply and you can get it to spark once when you want it to. Or, let it spark all the time (through the default gap) and use the gattling mechanism to shunt the spark to the correct chamber at the correct time.

It really isn't worth dicking around with a homebuilt stungun.

Buy from bcarms and tell him on the order form to remove circuit from the casing, that way your receiving a circuit, not a stungun. Worked for me, they are not permitted where I live either.

The easiest way to go about this is to pick up a BBQ sparker that is powered off a 1.5V battery. I bought mine at Canadian Tire.

After that, you'll want to look into an ignition coil driving circuit a la Jimmy101.

And if you can't find an ignition coil, gogo BCArms!

I say your best option is to go with BCARMS's <strike>stungun</strike> high-voltage power supply. If you're still not comfortable with that, then the next thing is to use an ignition coil (easier than you think, just check out the Wiki).
