Re: [Ee] Field mill

Funny you should mention it, I used to teach electronics. I have a transparent classroom meter meant for placing on an overhead projector. I'd need to dig it out to see if it is center zero, I doubt it is. If so, it's yours if you want it, my classroom days are long over.

I have no idea where to find one, but a LARGE analog meter, center zero, of
10 to 100uA could work. It would have to be illuminated.  I know they used
to make such for classroom use, but probably hen's toothbrushes today.
Visible at 50' or more, in the dark, is the key.
