    Clockwork Light Meter

    Is it possible to make a clockwork light meter? If so, would I be the only person who may use one?

    How on Earth would such a thing work? The old meters used Selenium cells which turned light into an electrical signal which then registers on the meter. I don't see where winding it up would come into it.

    You wind up the clockwork. The clockwork train turns a tiny regulated generator which supplies 2.7 volts to your LunaPro. That's about as close as you can come to a clockwork lightmeter.

    We have wind up radios, as endorsed by Nelson Mandela, so why not a wind up light meter?

    There could also be a gear train which, when you line a pointer up to the needle, turns the exposure calculator to show the setting.

    I imagine some kind of Steampunk-looking gizmo with lots of brass gears and stuff. Sort of like an Argus C3 on steroids.

    Maybe something like this:

    That sounds like what I'm looking for.
