Very small windturbine (part 2)

Supplement of a science magazine named "OtonaNoKagaku Vol.18" in Japan.
--------------------------------------
1) Generates 6.8 VAC and 7.7 mA at 3.5 m/s wind speed.
2) Brand-New generator: Neodymium magnet and
specially volume-up'ed coil (0.05mm x 100m)
3) Very thin tubular PET blades :100mm (length)
x 50mm (base width) x 30mm (tip width) x 0.4mm(thickness)
4) An ultra bright red LED
5) Plastics covered: Suitable outdoor-use
--------------------------------------
I modified it from "down-wind" style of the original
one to "up-wind" style.
Because generator shaft with blades slipping-off
trouble occurred by gusty wind.
