PIGEON SCARECROW |
|
I have an area on my roof where a large flock of pigeons like to roost. Their
nesting materials and droppings really make a mess. Often there is enough junk from them
that it clogs my roof gutters. Perhaps one way to scare them away is with a device
mounted on the roof near their favorite roosting spot. The device could contain an
infrared motion detector. When it detected their motion, a spring loaded cover
would suddenly pop up, like a jack-in-the-box. The thing could be equipped with a small
solar panel, which could charge up either a super capacitor or a long life battery.
After each pop up activation, a motor would pull the cover down into the body of the
box. A solenoid brake would lock the system in place, making it ready for another
cycle. I think the device could be camouflaged to look like a standard roof vent.

Perhaps instead of using an infrared motion detector to activate the device, it could
just go through a cycle every 10 minutes or so. It could also contain daylight
sensor so at night, the number of activations would be reduced to perhaps once every 30
or 60 minutes. This should extend battery life. |
