7400 competition entry: Heat generator

After being discouraged by a failed order for their initial entry, Ben and his girlfriend decided to enter a somewhat different design into the Open 7400 Logic Competition. It consists of taking their anger out on 7400 chip. By pumping 1 Amp of current at 12V into the IC, they turned it into a heater, and a firecracker a few minutes later. Check it out in a video below.
