Notes from experiments 02 Dec 2007
We built and tested our first go at the Bedini Simplified Schoolgirl (SSG). We were unsuccessful in getting the motor freely running. We think this is because of two issues. First, our coil had 260 turns instead of the recommended ~900 (I ran out). I'm ordering the proper size magnet wire and winding this week. We're also ordering lots of "Ceramic 5" magnets for a re-vamp of the wheel. Our second potential issue was running the SSG from a lab power supply instead of a 12V battery. Once we got a good starting spin of the wheel, the PS would current limit. My guess is that we were getting a proper trigger signal, but couldn't pull enough power from the supply to provide enough coil power. This will be corrected next week. Pictures and video will follow once we get a running system.
