The goal was to build a wind powered generator from a cordless drill. It could be used to charge up a battery. The battery could then be hooked up to a light bulb from a car or a string of LED lights. Handy for a shed, outbuilding, pump house, boat, small room or workshop. The video just covers the basics and like many of the Cedar Workshop videos, it’s for learning and having fun.
Started out removing the leads to the trigger, made a hub from a 4-1/2″ v-belt pulley, attached blades, and ran some drill press tests. The factory gearing on the small DC motor presented some interesting results. To simulate a high-speed wind turbine, the cordless drill was attached to a drill press running at 792 rpm. The results were interesting. The low (driver setting) produced 4+ amps and just over 18 volts, but was hard to turn. The high-speed setting (for drilling) produced a low 6 volts and a dismal .8 amps.
The next step is add a rudder, mount it to a pole and get some real world feed back.
