I'm just popping in to P3D infrequently these days, but this caught my eye.
I would appreciate an email from whoever started this thread or whoever is
actually building the circuit, once the thing is working.  (Or post to P3D)
Actually a circuit diagram posted to the web would be ideal.  I am
electrically non-gifted, but would love to build an illuminator for my
Berezin "super-sharp" viewers.  The different light boxes I have tried
(fluorescent) are battery hogs and not very bright and too big to be
convenient.

Thanks, Boris
