Hello
I have 4-5 Charge Coupled Devices out of scanners and fax machines I have dissected over the years, and I was wondering if there was any way to hook these up to the Arduino. If so, what data would I get?
This is essentially what they look like: http://www.spectronicdevices.com/images/oemelectronics.jpg

Depending on the device, you'll either get a mono or and RGB signal.
Basically, if it came from a color system (scanner - fax machine may likely be mono only), the pins on the device will possibly be set up for so many for Red, Green, and Blue output signals, with clocking signals to clock out the date. There will probably be a reset line, and several others (power, ground, etc). Depending on the device, the signal lines could output analog voltage levels for each clock pulse, or a digital level (that is, there will be multiple pins to output a value in binary). On a mono chip, there would just be one line (analog) or set of lines (digital) for gray levels.
The sensors themselves are very simple devices overall; if you can find out what the devices are (are there any numbers on the devices? other markings? you may have to desolder one and look on the bottom between the pins) - you -might- be able to find a datasheet. That will be key. If you can't find a datasheet, and the device it came out of no longer works (precluding the ability to reverse engineer the signals/protocol), then you are more or less SOL, unfortunately.
They do however make great paperweights...
