In case purely visual means fail

It’s the one and only (I assume) buttcrack detector, using the nifty LilyPad version of the open-source Arduino board, which works like this:

using a Lilypad Arduino, vibrating motor, and a photoresistor (measures the amount of light in your coin slot), you will make a wearable apparatus. when the photoresistor/your coin slot is covered, the hip-pack is at rest, when it/your coin slot is exposed, this triggers the vibrating motor to start vibrating & let the user know.

The trick, of course, is to get the likely offenders to wear the darn thing in the first place.

    Evidently, the people I know who routinely expose buttcrack are a bit more wild than the ones you know, because I can imagine several of them intentionally exposing their coin slots just to get the buzz.
