How to install LED eyes on a wooden lawn deco bird and power it with wings that move and rotate with the wind? Answered
We have a flamingo bird, a wooden lawn ornament (of course), called a "Whirlygig" by some, whose wings rotate when the wind picks up. I would like to know if there is a way to harness the energy from the rotating action of the wings to power a couple of LED lights used as the eyes on the bird. When the wind picks up, the wings begin to rotate very fast and at the same time, the LED eyes would glow brightly. The body of the bird is a flat piece of 3/4 inch wood so a 9 v battery wouldn't fit well and would interfere with the rotating wings.
Could the rotating wings accommodate some sort of dynamo effect to power the LED eyes? What about some bare copper wires glued to the inside of the wings and a magnet glued to the body? With the rotating wings and copper wires, wouldn't there be enough voltage to power a couple of LEDs? A solar panel would be nice but we want the eyes to light up at night when the wind picks up. Any ideas?
