Cat Dissuader

Printed parts for a motion triggered cat squirter, to keep them out of the bathtub.

Uses an unmodified Super Soaker Hydrostorm motorized water pistol as the squirting mechanism by replacing the battery pack with a printed replacement, with power switched from a 9V wall wart through a relay. Also includes printed parts for a suitable if quick-and-dirty Arduino case, a PIR mount to hold the sensor at a 45 degree angle, and a prop for the Hydrostorm to hold it at the proper angle.
