Do your best Linda Blair impersonation with the "Princess and the Pea" alarm clock, an amusing automatic wake-up contraption:

No ordinary alarm clock: the Princess and the Pea Alarm Clock ("PPAC") leaves no room for snoozing, inflating a green "pea" between the mattress and box spring, making it impossible to stay in bed. In the tin can, a homemade Arduino-compatible board with clock and memory chips handles the alarm clock functions, and a power block under the night stand provides power and relays driving the sprinkler valve or other alarming alarm functions.
