umm, this is actually for a handheld...dunno how that would work lol
And a thought...can i buy a commercial induction coil from an autozone or something similar?

You can probably buy the ignition coil from autozone, yes. You can just use a couple 9 volts also. Throw those and a switch into a project box and you're good to go.Just not that the coil will spark whenever the electricity flow changes. That means when you flip the switch on, and off, not just when you flip it on.

EDIT: Autozone's website tells me that I could get an ignition coil for a 2000 Silverado for 32 bucks. It made me pick a car, you can probably get a cheaper one.

wait...so if im using a pushbutton switch.. it would fire on both the pull and release? lol that could be bad
way to combat this problem? use an actual transformer circuit i'd imagine

It wouldn't be bad. Just an extra spark.

Drew up a quick circuit for you.



And you won't be to use a transformer from a monitor since you have to have a seperate electrical driver to run it.

Edit: Crud, didn't see the other posts.

whats the box in the bottom right? a project box?
And the black+yellow thing is?
lol been so long since i've read a circuit diagram...i might have to break out the manuals

No not a project box, it was just to seperate the simple spark pulg I drew form the rest of the diagram.

And the black thing is wires going from the igniton coil, and the yellow thing is a spark.

He said bottom right, not left. That is a project box. You can put the switch, capacitor, flash tube, and batteries in there. Though I must confess, I don't know what the flash tube is for.

box on the bottom right that contains nothing but just connects the trigger, flash tube, and capacitator-thats the one i mean
does it just signify that they are all connected?
Could you explain what a flash tube is?
Are we talking about a camera flash circuit?
And the spark plug is connected to the - side of the spark gap in that diagram correct? the other one is connected to the conductive chamber right?

I haven't got a clue what the flash tube is. For a while I wanted to build my own induction coil, and there was no flash tube in the diagrams. Just the power source and capacitor. And a switch.

Aw sorry Thats supposed to be the circuit bored for the camera flash.

The flash tube is like the switch between the capacitor and the coil, but unlike the switch, it won't weld together after a few uses. So instead of wasting switches, you can use the flash tube as a switch by triggering it to flash like you normally would.

And your right isomer, the one wire of the spark gap is connected to the chamber (which is connected to the middle connector on the ignition coil) and the other is connected to the ignition coil - screw.

mk cool thx-message too short lol

Chances are you'll have to replace parts in any home made ignition system. Piezo BBQ lighters last about as long, on average, as any other setup.

Fortunately for you, several contributors to this forum are not too lazy to try to answer your questions.

Given the above posts you shouldn't even be considering an automotive coil, or flash circuit or anything else that requires more than three parts. Either get a piezo or battery operated BBQ ignitor, or better still, a stun gun. If stun guns are illegal where you live than get one that has been converted into a "high voltage power source" from BCARMS.

Why would that be bad? The gun'll fire on the first spark, the second would be irrelevant. Besides, automotive coils generally spark when the current flow is stopped, not when it starts.

Jimmy, I don't like your pessimism. If everyone thought like you, we'd still be in the dark ages.
