Introduction: Party Popper Alarm Clock
Party Popper Alarm Clock - More information
Instead of some litte beeps or squeaks this alarm sets off a party popper, guaranteed to wake you with a start!
The base and clock circuitry come from a "Flying Alarm Clock". Originally when the alarm was on a motor would be set high, now the input is into a Picaxe microcontroller. When the Picaxe detects the input is high it sends a signal to a servo that moves from one extreme position to another. The servo is connected by a chain to a crocodile clip that is connected to the string of the party popper.
