**********Thats part of the trickster nature of this
circuit - it varies depending on what I do on the DC
side of the AV plugs!  Generally speaking, I am
running a 12 volt pack of AA cells with a 100uF cap
across them and a 100mH inductor in series.  Current
draw with all strings running in a "typical mode" is
50 to 55 mA.  Pin is therefore usually 600 to 900 mW.

Here is the core issue, though - or rather two of
them:

1.  As I gather from perusing the Hartmann board,
different antennae or attachments to the driver side
can boost the power delivered to the LEDs.  The most
effective place for the "extra" is attached to the V+
point or collector.  This can be a wire antenna, or
one of a number of Sam's large non-inductive coil
geometries, or a big homemade cylinder capacitor, etc.

2.  The trickier part though has to do with metering
the current through the LED strings.  Even with 1 uF
caps across the AV plug DC side, attaching a meter to
or even touching the LED string can cause a jump in
current in that string, drawing down the brightness of
the other strings, and causing a jump in battery
current on the other side of the system.  It's
possible I could be re-introducing RF back into that
closed isolated AV circuit.  I dunno.  What I did for
all LED strings and the battery side was to make some
very precise 1.0 ohm nichrome wire "resistors" and put
them in series.  That way I can use high input
impedence DVMs to read millivolts across the 1 ohm
value.

*********Thats an interesting twist.  I woulda thought
we are way above that in frequency, but OK, I may have
a couple of those to try.  Thank you.

********* Most of the times I attempt multi-point
measurements at one whack, I come up with a ratio of
Pout to Pin between 78% and 95%.  Which honestly is
surprising enough for me, that it could be that
efficient of a conversion.  I would say the most
outrageous value that did seem to be as legitimate as
my measurements at the time - and again, I state for
the record that it certainly implies an artifact
somewhere - was COP 1.1

In all this I had not yet touched on the other side
excursion that I am still playing with, which is a
little puzzler, but more in the way of science fun. 
I've seen some slight effect where the color and
sequence of LEDs in a long series string make an
impact on the total current, even with a DC supply set
to a constant voltage.  In other words, I start with
orange (O), green (G), and white (W) - in which the
band gaps are in ascending order as listed.  Well, a
long series of OOOOOOOO-GGGGGGGG-WWWWWWWW draws more
current for the same Vin than OGBOGWOGWOGW and so on. 
The differences are usually less than about 10%, but
seem to be reproducible so far.  I need to try it much
more formally with a broader range of colors /
bandgaps.  BTW, my AV plug LED strings are arranged in
spectral order with 10 of each color per string, six
colors, ROYGBV from cathode to anode.  Rainbows in the
dark! (apologies to Dio;)

The Holy Grail 'neath ancient Roslin waits.
The blade and chalice guarding o'er Her gates. 
Adorned in the masters' loving art, She lies;
She rests at last beneath the starry skies.
