Wow!!! Well I watched a few other of that guys videos he is BRILLIANT!!! Some people have intellegence and patience to go along with it. His counter was an idea I had several years ago, then I though a mechanical one with micro switch might be more accurate. Each have their advantages and disadvantages, but for what he and I would be doing both are fine for hand winding.
Does anyone know why on RF chokes like that you want the windings patterned like that, what does that do for the choke?
