Car Horn Alarm Clock

This Car Horn Alarm Clock is sure to wake you up in the morning. Not sure if the volume would beat my Fire Alarm Bell Alarm Clock but either is sure to get the job done. The clock in this hack has a nice small motor that is activated to ring the alarm on the stock unit. A small transistor is used to drive a mosfet to handle the large current needed for the car horn.
