My buddy's dad was an EE and built tiny devices made to create this exact situation. Easily hidable, they emitted a loud beep sound at a varying interval (~40-120 seconds). He called them Annoyers and would leave them behind pictures frames, in plants, etc. after parties.
- framebit 9y agoThere's a version of these called the Annoyatron that you buy online. Know how I know this? Because one of them was left behind a cabinet in a rental house we moved into and we couldn't find what was making that damn noise for three months!

- TeMPOraL 9y agoI think this one is even more evil, because it forces you search in the dark. This in fact is a very popular around the world electronic kit for beginner hobbyists, because it's trivial to build and has only few components. I remember it from electronics magazines in Poland.
