Fire Alarm Bell Alarm Clock Will Wake You Up

posted by Scott Beale on Monday, January 14th, 2008

Have trouble waking up in the morning? Alan Parekh of Hacked Gadgets has a solution, make your own Fire Alarm Bell Alarm Clock.

Ever sleep-in because your alarm clock wasn’t loud enough? With this design that is guaranteed not to happen! This hack takes a standard cheap alarm clock, some interface components and a fire alarm bell to get the job done right. Normally these small alarm clocks use a piezo buzzer to attempt to wake you up. The alarm signal is hijacked from the clock circuit board and used as an input to the interface board.
