Taking data towards making this a real wind generator
test day 1
I spent a nice breezy fall day taking data on the wind generator. I definitely need more output voltage to be useable in light winds,my initial test was behind the garage so I would be shielded from the 35 mph gust. My back yard is surrounded by trees that are 70-100 feet tall, so I was not able to get into the real wind, but was able to get some useful information.
I never saw more than 1.5 V on the output. Pretty low, and not much good for generating serious power.
I suspect that had the thing been on top of a 200 foot tower, it would have been really cranking.
