DIY Electronic Firework Igniter

A homemade 7KV firework igniter using a 3v to 7000v boost converter from eBay.

I’m feeding the boost converter with an 18650 battery, anywhere from around 3V to 4.2V.

It produces quite a nice high voltage arc, with adjustable distance. Although this design doesn’t lend itself to a large arc distance due to the placement of the paperclips.

A better design would be to glue the paperclips to the side of the battery holder so there’s a good distance between them and to ensure the arc appears where you’d intend it to.

This is a great idea,  I recently bought one of those HV boost converters.  Would it be possible to adapt your idea to make it spark using a remote control?  Thank you… John… 🙂

A simple DIY electronic firework lighter / igniter. Similar to commercially sold products and to the electric cigarette lighters on Amazon/eBay.
