Just a little bit showing my home made hot wire cutter and how I use it to cut out depron foam rc plane parts. more info at www.1bad69.com For everyone commenting on using a lipo for this: Lipos (at least ones used for RC stuff) can commonly handle high current loads. In this case it was at least a 10C 1300 mah, which by definition can sustain at least 13 amps. Where you have issues with lipos is pulling to many amps from it. A direct short will attempt to pull many more than 13 amps, and things will start puffing and melting. My circuit is NOT a direct short. It contains stainless steel wire, which is a poor conductor, and has a high resistance. This resistance is what causes the heat that cuts the foam. Changing the length of the wire will change the resistance which changes the amps drawn and the heat created. I SHOWED in the video, checking this with an amp meter, to show that it is only pulling 2 amps!! well below what this lipo can provide. IF you make sure you are pulling less amps than what the battery can provide, there are no issues!!
