This may seem simple or out there to most of you guys and galls, but I don't know much about this stuff. I am making a simulator for training and I need to use a small count down timer but I can't find one that is loud enough for the application.

What I need to do is take the small timer and add a after market buzzer to it so when the time has ended the buzzer will sound for 1 to 3 seconds.

I am thinking I will need an alternet power sorce that uses a relay activation, but have no clue on where to start with any design. The internal buzzer can most likely be removed and use the power from that timers power sorce to initiate a relay, which (I think) can be used to access a higher power (say 9V) for the louder buzzer. The timer uses watch batteries.

If any one can help Please Do! If you have a defferent Idea or another salution then what I'm thinking please help.

Thanks.
John
