my previous post about an alarmclock based contraption got several "helpful" replies from some people. i have a digital alarm clock, and i need to know what part of the board controls the *BEEP BEEP BEEP BEEP* part, and if it can work similarly to the diagram provided below. if it is an overcomplicated solution to a simple problem, please let me know, and provide a simpler solution using the same materials. please no rube goldberg contraptions.







A: Clock is plugged into wall. B: alarm goes off sending a signal. C: motor with gear recieives signal and begins to turn. D&E: Ruber band pulls trigger on spray bottle, waking me from my slumber.

 

When I was about 14 years old I made an alarm radio using a standard mechanical clock.



I removed the bells and replaced the hammer with simple switch contacts. When the alarm was triggered, the switch would close and turn on the radio.

 

it's probably the micro pulsing a piezo buzzer, take a picure ofthe inside of your clock pcb ..
