I can build this into my new programmable inductor module, for
self-test. With a 1% cap, it should be plenty good. L range will be
750 mH down to maybe 10 mH, part of simulating solenoids and torque
motors and such.
If I add a switch to open R3 and run some current through R1, it can
measure series resistance too.
