Hi Chris, and all,

Wow!....thanks for the references and all the very patient help.  The
Centronic units I have, do have all the characteristics you advise
against....ha...even to the blue enhancement.  They are round cans,
and look to be filled with some clear substance that even encases the
photovoltiacs themselves...they can't be salvaged for use...I've
already tried that.   The web address is:

Yes indeed this all helps....actually it all decidedly enhances the
pursuit
of opto-electronics for overall amateur seismology in my opinion.
Some things were a surprise in their discussion, use and even the
extraordinary logical selection of such.  For my current use, I have to
use this approach; as its for a diamagnetic levitated spectoscopic
graphite
rod used as a tiltmeter/seismometer.  I'am convinced I need to scrap
some previous electronic parts, and get some better material....the
results
will likely be much more accurate in the overall evaluation experiment,
than what I could dredge up alone...ha.

Many thanks to all,

Meredith Lamb
