I wanted a
slave flash trigger [...]. My design used a small PIC,
[...]. It runs for months on a single CR2032, [...]
Yes, but an Arduino is seldom
part of that solution space for the
low-power domain.
True. I'm sure it's possible to get lower-power than a 555, too, in
the non-processor solution space. I was really comparing the
first-reaction "use a processor" solution to the first-reaction "use
discretes and maybe simple LSI" solution.
The camera drew enough power that a milliamp this way or that in
control circuit draw was pretty much ignorable, though, so there was
little incentive to put more human time into improving it, especially
in view of the limited amount of improvement that was even possible.
