Step 6Stick it in your...
window and open a window on the opposite side of the house, the video shows it in operation, careful tuning of the belt tension causes the the voice coil to resonate, that's a good thing. Measured power output is 1.5 Volts AC with a short circuit current of 20 ma. The leads from the coil are attached to two LEDs wired in parallel with reverse polarities as suggested by Kiteman.
Suggested areas for exploration, personal and general.
I didn't rebalance the voice coil, I'd also like to try paring one down to reduce it's mass.
Hand wind (or stack multiples of) the coil to increase voltage output.
Try various belt materials.
Acquire some schottky diodes and make a voltage multiplying rectifier.
perhaps follow that with a blocking oscillator for battery charging.
Just thoughts.
And finally a Thank You to Alan Parekh for the LED's

Very, very nice. perhaps putting such a thing across the roof of your house might be nice. try getting energy from a flapping flag.. they are not illegal yet! thanks for sharing with us.. good for you! joe
