How do I connect an electronic kitchen timer to speakers to amplify the sound?
My friends and I play a lot of paintball and we are trying to create a mission to destroy a target. I had originally thought that we could use a kitchen timer as the detonator to set the time and connect it to speakers or even a smoke detector to blast the alarm load when the timer has ended.
I know the basics of following wires and can do some soldering, but I am NO Engineer... please keep it simple.
Does anyone have any ideas; all help is welcome. Thanks!
Take the timer apart and identify the sounder, which will not look like a regular loudspeaker, but is a small round disc fed by two wires. There may be solder tags on this item (it is actually a piezoelectric transducer) or at the other ends of the wires. Solder wires to these two points and bring them out of the casing. These are to go to the input of a powered speaker, such as any computer loudspeaker, or any other amplifier/speaker combination you have. You will need an amplifier, because the original timer will not have sufficient power for a proper loudspeaker. If you use a computer loudspeaker, you will need either a socket to match the little jack plug or to cut the plug off and solder directly. I recommend getting a line socket to match the plug, which has 3 contacts. The tip is one channel input, the next is the other channel input and the last is the common earth. Solder one of your wires to the 2 socket tags corresponding to channel inputs, and the other one to the common earth tag.
