Electronic – Is it possible to fire a spark plug from batteries

capacitorchargingdischarge

I wanted to create a remote fired trigger for a spud gun so I can trigger it remotely.

Ideally I'd like to use a spark plug to fire because it should work well for gas mixtures but the trigger is pretty small/simple. Basically it's a a little remote box with a push button trigger that runs off of batteries.

It has a light, arm switch, and push button that triggers a relay but I currently don't have anything connected on the relay switch end.

Would it be possible to charge up some caps and get enough juice to bridge a spark plug with a small battery source (4 AAA or AA batteries) or would I need to step it up to something bigger (lipo or lead acid).

Note: I have used caps for filtering before but never for charging/discharging.

Update:

Just wanted to clarify. I know that a gas grill push-button igniter is a viable option but I'm looking for something more reliable. Ie, an igniter that I'm 100% positive it'll fire a good spark when I push the button. Check out "Tater gun Fires a Hunert yards" to see what I mean by unreliable.

The answer for automotive spark plugs is no with a normal battery. But with a 9v battery by stepping up the current using a ignition coil (which ramps it up thousands of volts) then you will be able to use a spark plug....Only thing with that though is that your battery (9v) won't last long, as its "Juice" will be all gone in a few shots. Hope this made sense :) just tell me if not....

You could make a spark though with your normal everyday disposable camera....Something like this: http://www.angelfire.com/80s/sixmhz/camera.html

P.S: If you used a larger battery (more volts) then you would have more juice :)
