Hello: I am trying to make a homemade circuit to do underwater detection of old War 1812 US Navy ship cannons. Magnetometers can be bought, but they are expensive. So, I am looking at a metal detection type circuit. I came across the Maxwell Bridge circuit. See: https://en.wikipedia.org/wiki/Maxwell_bridge Here I would increase the ac frequency to make a coil Q of the required n...

Actually, we do this too, differentiate a product by one bit set somewhere that enables a feature. That's sort of selling intellectual property. It's also a way to get at two points on the usually-unknown sales-vs-price curve. -- John Larkin
