I don't have an old or new digital camera. I'm somewhat interested in
the possibility of building a CCD camera, following Richard Berry's CCD
Camera Cookbook, but the Willmann-Bell website estimates it will cost
between $350 and $500, the more optimistic figure being based on the
assumption (false in my case) that one has one's own metal working shop
and the skill to make some of the parts. That's way out of reach for me.
if you are thinking about getting the ccd out of an existing camera.
If you want to learn something, and that's debatable, then you'd be
better off starting with a camera and studying what's inside. You're
going to come out far ahead.
This is no different from when I said when extracting parts from
scrap equipment, you can get information from the circuitry that surrounds
it. Given that you are talking about building a camera from a camera,
there's really no reason to extract the CCD and then wonder about the
rest.
If you actually want to learn the basics, then go back 30 years. That's
when digital cameras were virtually non-existent, and if one wanted to
play they'd find a suitable dynamic ram IC, pull the top off and put
it in circuitry to scan the rows and columns. That was what was in
"The Cyclops" in Popular Electronics circa 1976. I remember the
basic concept was shown elsewhere afterwards. But then you are
actually playing with the basics, pull a CCD now and it's so highly
integrated there's not much way to put it back together other than
the way the manufacture designed it to be put together.
