Whats the Easiest Spark strip to build ? and fan power ?

[Rob748]

My Last Advanced Combustion cannon before I go experimenting with a steel hybird thats like really small lol.

Any ways

4 inch chamber by 20 inches Long, 2 Fans 3 inch and the other is a 92 mm fan. Havent Got the mapp gas yet but I a planning on it soon.
I got a gas/grill sparker powered by a double a that Id like to get 3-4 sparks out of it. Whats the easiest way to build a spark strip ? Any suggestions are welcome, ive looked all over and the only one I found that I think Id like to try is the spark strip in the triple thunder cannons.

Thanks

Triple thunder had a milled gap and rod embebbed in it.

If you want ease, I can recommend copper tape (used in lead-lighting) over a 1/2" piece of PVC cut in half horizontally, then use a sharp knife to cut the gaps. Very fast, but in the long term it may suffer.

yeah but that sounds like its on the wall of the chamber. I think
I think I will just go with the triple thunder cannon spark strip. Thanks for the suggestion.

Hey do you know a way to power a chamber fan, better than a 9 volt ?. How can you use multiple 1.5v to power it ?. Is there anyway you can get the fas to run at full power ?. And would 2 Chamber Fans be to much ? or just be better ?

Yep, multiple 1.5s will work just fine. 9v will drive the fans ok but I would go with at least 12v or 8 - 1.5v's in series. You will be able to run 2 fans but the fan batteries will run out twice as fast....small price to pay right...for dual fans...?

You could also run your fans off a rechargeable battery for airsoft or radio controlled cars.

I mean put the copper tape on a 1/2" piece of PVC, cut the gaps and mount it in basically the same was as triple thunder.

If you want to, you can wire 1.5V's in series but the most cost efficient was is to use sub-c rechargeable batteries.
