Self powered AVR anemometer

Windmetter or so called anemometer measures wind speed up to 17 meters/s. Wind speed is measured and logged over period of 1/12 of a year and is stored for 11 months. Log can be read any time by connecting a computer to station. Anemometer is self powered from solar panel, which provides enough energy to run AVR ATmega88 controller circuit.
