ISorry I've been away lately.
Runaway Pancake, thanks for your chart there. It's nice to back up with experimentation what everyone was saying would happen.

Late to this party, questions for the OP. How long to the AA cells need to last? What is the source of the 12V supply?[/quote] I'm planning a timelapse controller. It probably would only be run for 4 hours maximum at a time. The 12V would be from a SLA or Li-ion battery or whatever the user wants to take into the field for power.
