The Wake n' Bacon is a prototype for an alarm clock that wakes you to the smell of cooking bacon. It accomplishes this by means of a computer-controlled homemade EasyBake lightbulb oven, into which you load a slice of bacon in a pan every night before bed. Twenty minutes before your alarm goes off, the oven begins slow-cooking the pork-product. Great idea, but there are two critical flaws: it's probably not sanitary to leave bacon sitting at room-temp overnight; and now that I use my mobile phone for an alarm clock, this kind of thing is too bulky to consider as a practical add-on for my wake-up system.
