I saw your video on You Tube about the 'generator' you wife built but the pictures were a little fuzzy and then of course you played music, but did not really explain anything. I have taken electronics courses and have a Assoc. in Electronics Engineering.
I've unfortunately just worked in alternative fields just to get by in this economy.
Do you have a more 'complete' description of the generator and components? I'm guessing this is a DC generator.
