Electronic Cat Repellant

[Cat repellant pic]

This cruel project was inspired by a certain pet's habit of using the area under my desk as a bathroom. It comprises a commercial PIR sensor relay module, fire alarm siren, and 12V power supply, all from various dumpsters. No calibration was needed; this was a highly effective deterrent as assembled. The only drawback was that the beast didn't hew to a set schedule, and 4:00AM is never a pleasant time for a fire alarm. Note the not-so-new-in-box GRiD PalmPad 2351 in the background.
