Help dismantling an electric BBQ igniter

Unread postAuthor: eXodus31337 » Sat Jun 11, 2011 5:08 pm

I'm dismantling an electric BBQ igniter so I can fit it in the wooden handle of my spud gun.

I'm both ignorant and the biggest wuss when it comes to electricity. Could you help me dismantle this without shocking myself? I mean, is there any danger from the transformer or is shorting the capacitor enough to make the circuit safe to manipulate?

And the blue cylinder marked 250v is the capacitor, right?

Thanks

yes the blue cylinder is the capacitor. Just cut the plastic off, checking behind not to cut the circuitry.then hook your battery wires and trigger up!.

Why do you want to take this all apart? To make sure the capacitor is safe to handle, remove any power sources then use an insulated screwdriver and close the circuit across the two leads.

it is too bulky to fit in the wooden handle

Thanks for the replies, I needed to confirm the capacitor was the only concern

The transformer is buried under a solid centimeter of plastic...it's a pain to reach

Well good luck reconstructing the circuitry exactly in a different setup. It'll be a heck of a lot of soldering.

The transformer is potted to keep out moisture and prevent arcing at the transformer. Cutting it out will most likely destroy it.

Would it keep those problems from happening if I injected hot glue once in the handle of the canon?

Can you show us a picture of the spud gun handle? It might help us figure out a way to help you mount it instead of taking it apart.

I suggest using a piezo instead, if size is so much of an issue.. It's simpler and far smaller.

Ah ok. Yeah, just use a regular sparker. It would be easier, but may not yield take a bit more time to fire off.
