USE: Just put a couple strips of pre-cooked bacon on a paper towel in the teflon cooking tray the night before, and set the Cook Time for 4 minutes. Set your alarm for 7am and by 7:04 your bedroom is filled with the strong aroma of cooking bacon. You can then use the included tongs to pull out the cooking tray and eat the bacon without getting your fingers greasy.
Before I discovered pre-cooked bacon, I used frozen strips of raw bacon to keep them from spoiling overnight and cooked them at a longer cooking time.
HOW: First, we hacked a cheap alarm clock. When the alarm goes off in an alarm clock, the clock is sending a signal in the form of a wavelength along a wire to a small speaker to generate the alarm sound. We cut that wire and re-routed it to a pin on a microchip, and programmed that microchip to respond to that particular wavelength input by triggering a relay (essentially an on/off switch) to send power to a pair of halogen lightbulbs that safely
heat the bacon to a crisp.
