12.3 Electric Scarecrow
Have critter problems been plaguing your vegetable garden? Shoo those problems away using a smarter approach. Go beyond the picturesque but functionally pointless static scarecrow by bringing it to life with the help of a motion detector and a couple of heavy-duty servos. When that pesky rabbit comes by for its evening grazing on your plants, the scarecrow’s sensor will bring it to life, moving its arms and legs in a convincing way to frighten the rabbit away. Have your scarecrow email a photo of its animal detection activities with the help of an Android camera phone seated inside the scarecrow’s head.
