Is it possible to make a clockwork light meter? If so, would I be the only person who may use one?
What would the clockwork be doing? I really cannot imagine hopw you could have such a thing.
What is a clockwork light meter?
Of course not.
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 was a mechanical light meter gizmo of sorts posted years ago...
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.
You know, one of the characters in the movie, "Harry Potter," (Colin Creevey) used an Argus C3.
Just by itself, the C3 looks pretty Steampunk. With a little wood and brass cosmetics, it would be the genuine article! With a Steampunk styled light meter, it would make a perfect combo!
(Or fit right in to a HP movie. )
Oh so it's a wind up meter. Doesn't need clock work with escapement.
I think this post is a 'wind-up'
But can you mount it on the hot shoe of your camera?
As I pointed out above, clockwork cannot by it's nature measure light. The wind up radios use the machanism I described above, or have no clockwork and the user turns the generator directly by a small crank. The actual radio is no different from any other radio deriving it's power from a chemical battery, photovoltaic battery, or mains voltage.
Sure, got duck tape?
