Heat Proof Wire Sleeve

Kapton tape or fiberglass sleeving for wires

Are you sure a red-hot wire can even ignite the torch?

Maybe just use more power and longer wire?

My wire arrives tomorrow, I can do some testing then.

Your going to need a spark not a glow if your ignighting gas.

Bumping out of personal interest though.

Some central heating furnaces light gas with a hot electric eminent rather than a spark. This is not just some nichrome wire though, it's a ceramic looking material.

I've looked high and low for making a spark with an Arduino. I've found "high voltage generators" on Amazon that would technically work, but are too heavy.

You can buy electronic barbecue grill igniters that run on AA batteries and have a button that produces a repeated spark.
That would be very easy to hook up to an arduino.
Search "electronic grill igniter", should find you plenty. They cost like 10-20 bucks.

Same here debating if I should just repurpose a zippo lighter sized tazer or use miscle wire to swing an arm across a cappacitor bank.

kapton is only good to 400-500F.

Fiberglass

Which is only good to 1200. Anything better would need to be a ceramic insulator with a post to wire through it.

Covered this in the original post. Too big and heavy

Those things are piezo sparkers, the action of pressing the button produces the high voltage needed to ignite the torch. Unless you use a linear motor to push the button, this won't work.

I'd just cannibalise an arc lighter, they cost like 6 dollars on AliExpress. Since it doesn't need to be reliable you could even just use an automotive coil if you have one lying around, but this would require a substantial power source.

>Those things are piezo sparkers
the ones with AA batteries aren't
just put a relay or transistor where the switch is

>>1154602
I didn't even know those existed. Probably the same circuitry as an arc lighter, but still interesting. $3 a piece on AliExpress, your housefire may vary.
