Hi Dan,
Just put a loop of wire and an LED on a long stick and start probing
around the primary with it. After a short while, you will get a
good feel for where the fields are and how well they energize the
LED. Possibly a useful toy for mapping out the primary fields and
how they react to transformers and such (conventional coils).
You have already thought of just using a current transformer as a
power transformer to run just about anything you want *;-))
Looking forward to your book this Friday. It is autographed? The
antique show says that signed copies are far more valuable 100 years
from now :-))
Cheers,
Terry

I just did some initial calculations, and i think i should be able
to adequately illuminate a single LED from a 1-2 turn coil on a PCB board.
Calculations:
Primary Coil (12uH)
LED Coil (0.3uH) 1-2 turns, 2 inch diameter on copper board
Coupling (calculated with MANDK) k = 0.02 (LED Coil about 2.5
inches below bottom turn of primary)
Avg Current for 300us pulse, 100Hz PRF is about 20mA. A bit high,
but for a ballpark, not too bad.
Time to prototype!!!
