08182009024 Homebrew fire alarm

William Ward built a fire alarm module to protect the shop’s laser cutter from any unauthorized thermal events. He designed it around an interesting UV sensor made by Hamamatsu, which uses a combination of the photoelectric effect and the gas multiplication effect to detect very small amounts of ultraviolet light. Future plans include adding a Twitter interface (of course!), and connecting it to a larger alarm system.
