This is my slot car controller arc lighter. Never thought I would be putting those words together in a sentence!

The controller is from a Scalextric type racetrack but a crappy, cheap version. I found a pair of them in the dump and thought they might come in handy for a build one day – and they did!

The main parts to the lighter are an arc generator which creates a very hot arc that can melt solder. It’s run on a li-ion battery and is re-chargeable.

I’ve been having a lot of fun trying different things to burn with this, although it has to be said, it’s not pleasant when you get a zap from the end!

It’s not a hard build but it is a little squashy inside the controller so you will might have to come up with some creative ways to get all the parts inside.
