sense small inductive changes from a coil, and use it as a sensor

I was looking at the Propeller object code site and noticed a contribution by Beau Schwabe (Parallax)·-· "sense small inductive changes from a coil, and use it as a sensor".
I would like to do this with a BS2. Has anyone done this with a BS2? Beau, can you modify your Propeller code to work with a BS2?

There are a few ways to sense small inductive changes... It would help if I can get a better feel as to what your exact goal is, before I make a suggestion.

In that case, I'm afraid the inductor application you mention will not work the way you want.
It is based on resonate frequency response characteristics of a coil with the proximity of a metal object, and will not work for measuring current.
When measuring current flowing through a 120VAC power cord you must take certain safety precautions into consideration.
Off the top of my head, a solution is beyond my scope at the moment, simply because I don't have the experience with 120VAC to provide a safe solution.
