Piezo Ignitor
 

Where can I find one of these. I'm looking to pick one up at a local store. I live pretty much near everything.

First try parts replacement for gas grills at a Home Depot or some other hardware store where they sell gas grill parts. Your best bet is looking for a business that specializes in gas grills and outdoor cooking stuff. As funny as it sounds, they are out there. If none of these can be found, carefully take apart an EMPTY long-reach butane lighter (the kind you pull with your trigger finger). Remember that a piezo igniter gives a high-voltage spark, and it being accidentally shocked by the igniter really hurts.

Would it happen to be for a potato cannon? ;)

You know it. I'm making a cool ignition system, hopefully.

Don't use a grill igniter... they are not very reliable. Trust me on this one. I just finished my fourth potato cannon setup: interchangeable barrels, muzzle breaks that throw flame, and a FLINT ingnitor. the first three I built used electronic ignition and were not nearly as reliable, they had maybe a 1 in 5launch rate, where as the flint one is good for 19 out of 20 launches. Plus they're alot cheaper.

The only, and I mean ONLY, benefit of electronic ignition is the ability to have multiple ignition points. I had a 9ft cannon (3 foot long, 4" combustion chamber, 6 foot long 2" barrel) that I wired two ignition points into, it was amazing when it worked, threw a caulking tube over a quarter mile, but it did not fire reliably.

My new one, being so much more relaible, is alot more fun. It also uses propae as a fuel. Propane is good because it's much cleaner, both for your gun and the enviroment, and cheaper, since all your money is buying fuel and not hair chemicals and advertising.

My brothers friend made a potato cannon, and used a taser for his ignigtion. He has some videos here: http://video.google.com/videosearch?...+wetzel+potato

As far as potato gun ignitions go, ive had no problems at all with the push button grill sparkers. The only caveat is to make sure you clean the contacts where the spark will jump every so often. (and thats only cuase i use hairspray, not clean burning propane) My guns shoot at least 90% of the tinme when i i have enough fuel in them. So if you are having problems with them experiment with different amounts of fuel and keep you bolts clean. If that doesnt work you may just have a bad ignitor
