Do this at your own risk.
Today is a good day to see how well this small wind turbine turns. The diy solar light is made up of 9 LEDs and powered by a single AA battery. The joule thief type circuitry makes this possible and on most days, enough charge is generated for the light to say lit the whole night. On rainy days, the AA battery can now be charged by this toy like wind turbine. The wind turbine can be bought in kit form from Windstuffnow.
