Very cool. I had exactly the same idea a while ago, but because I'm not 
much
of a hardware person, it didn't develop from there.

A related idea was to house bat detectors in boxes like that. They would
load during the day, and when it gets dark, they would turn the ultrasound
of bats flying around into human-audible sound.
