Archimedes Windmill with working generator

thingiverse

This is a remix with a stronger mounting bracket, a mount for a computer fan to generate electricity, a bridge rectifier to turn the pulses into DC current, a solar light circuit board to control charging/ photo control and a battery to store the energy. The cpu fan is torn down and the leads are directly wired to the coils of the motor because the cpu fan has a controller to drive the brushless motor. a small bridge rectifier turns the AC pulses into DC current. I used a solar landscape light for the circuit board that controls charging the battery and turning on an LED when it is dark enough to trigger the photocell. I painted the circuit board with insulating paint to stop rain from messing with it. elastic band is the coupler between the turbine and the generator. I didnt design it very well, many bandaid solutions to problems that came up. more of a prototype for a bigger design. I also put the generator on the wrong side and glued it in so oh well. should be on the back to help the wind move it in the direction of the wind like a tail. it has survived an 80 kph wind. Get your polluting birds off the grid!
