Lighters are too expensive. I decided to build an Electric Fuse Lighter that would create an arc of electricity that would light a flame. How I use the device is I click the metal switch to allow the capacitor to charge up. I then hook alligator clips onto the negative and positive wires and put them onto a fuse (close enough for them to spark). I click the black flip switch that allows the capacitor to discharge onto the wires which sparks the alligator clips and ignites the fuse of the firework.
The innards of the both consist of a disposable cameras photoflash capacitor, and lots of 22 gauge speaker wire. The Electronic Fuse Lighter runs off of one AA battery.
Unfortunately, this would only light the fuse 1/8 times that I tried it. Regardless, it was a great learning project! (Please ignore the hot glue, I got over-excited and wanted to see this working)
