Many alarm clocks have come out in the past few years, trying to get you from hitting the snooze button by requiring you to perform some act of groggy, post-oneiric dexterity (like hitting a target with a laser beam) or a teeth-grating act of pseudo-robotic annoyance (like an alarm clock that rolls off the table and goes rushing around the room, squealing).
Still, why accomplish with circuitry what you can accomplish with ear drum bursting sound? The $49.95 Sternreiter Twin-Bell alarm clock ring at a volume of over 86db. There is no snooze. You either wake up, turn it off, then vomit out your heart, or your friends find you a week later, lying in a pillow puddle of your own gelatinized brains.
