do this accept for the nichrome wire at the end attach it to the leads of your beeper, then hide in a high traffic room and laugh as it drives people crazy!

If you've got something that makes beeps, you need a switch. Give use some more information as to where you're having trouble with this?

What kind of battery depends on the beepy thing in question.
