A friend of mine wanted to be able to set off some fireworks from a safe distance. After a little research it was decideced that off the shelf products were too expensive,  so I came up with this.

At it’s heart all this does is create a short circuit accross a 10 ohm resistor. 12v will do a pretty good job of melting the resistor which would be simply taped to the firework fuse. As you can see in the following pictures it is simply powered by a 12volt cordless drill battery and even comes with it’s own carry case.
