I finally ran across this picture of the bicycle generator I had built a few years back. Overall I am glad to have done the project. However, I didn't use it very much. One of the main reasons is that doing exercise in a hot climate on a stationary bike, I was sweating profusely in less than ten minutes. The second reason is that we had solar panels and another whacky charger I had rigged up, so the bike generator was usually unnecessary.
