Re: Pinhole Light Meter

Yes your probably correct the current draw appeared borderline for a
Lithium. I believe that 6 Alkaline AA's gives better value and lifetime
though currently.

I have opened a discussion on the f295 forum
http://www.f295.org/Pinholeforum/forum/Blah.pl/Blah.pl?b-cm/m-1154672610/
as this list does not appear well used.

Does anyone know any more suitable place to discuss this than here and
f295?

All the best

John
