Ahhhh, I wondered what I had done with this email...
How are you doing? Getting a chance to use your meter & shutter much? Hope
so..
Had a Question for you...
Do you think this would be adaptable to UV light for metering
Daguerreotypes?
Happy Thanksgiving

Good progress has been made on the light meter and shutter driver. The light
meter now has a piezo buzzer and I / we are working on the maths for
accommodating various film's reciprocity characteristics. A few of these may
be available in various forms.
Check out the light meter thread on
http://www.f295.org/Pinholeforum/forum/Blah.pl/Blah.pl?b-cm/ for further
information.
The shutter driver can be use stand alone either driven by a 5V signal or
the press of a button.
All the best
John
