Varmint Detector

The thing is a “Varmint Detector”. Varmint: noun, North American informal - a troublesome wild animal. In my case, crows and chipmunks attacking our garden. They really aren’t much of a problem, this is just my excuse to build a solar powered device.

Scenario: animal moves in front of the detector, detector makes noise, detector wirelessly triggers other detectors, lots more noise, animal flees. https://youtu.be/fLsRnaet7TI
