Unexpectedly, I now own a working field mill.  The output is +/- 15V.  I
need a way to make that visual, without running cables. Cables conduct
lightning.

One way would be an LED bar, but no luck finding a center zero bipolar unit.

Another might be some remote reading meter, bluetooth maybe, but I really
need the analog meter action rather than digital.

Any ideas?
