Check out this awesome hack that involves a handheld flame thrower. There’s some schematics and build details here. The X-men-like handheld flame thrower uses hand gestures to control the amount of flame you want. I think this is way cool that you can build such a dangerous device but just make sure if you are going to build one, you know exactly what you are doing as even small mistakes could possibly burn your hand off. (so have a fire extinguisher nearby)
Prometheus is version 3 of the Pyro System. This is the culmination of about 6 months of thought and 2 months of building during whatever spare time I could find. This is just a basic demo video. I’ll be uploading a detail video with some design and component discussion later.
