    Hello helpful people of the Internet,

    I am trying to figure out what kind of electronic components or structural forms I would need to successfully build a snapping 'jaw' that would be operated by a motor (or many motors). The idea is to basically have a sensor activated wall of jaws that snaps at you... for a scary visceral effect... and without really getting into the details, I'd appreciate some possible solutions or helpful hints, essential reads, etc. Think (not as harmful) bear traps or those snapping crocodiles in Donkey Kong.

    :) Thanks!

    Have a set of "jaws" that are closed by a spring, and a cam attached to a geared motor which opens them and releases them as it turns.

    Trigger the motor from a PIR
