[Arm-netbook] DIY laptop part 2: camera

[David Niklas]

Hello,
I wanted to add a camera onto my laptop.
I located two suppliers:
blisscomputers.net
e-consystems.com
My problem is a lack of experience. I know how many MP and where the
camera should start focusing at (focal length at 30CM).
I don't know how long a reasonable MIPI-CSI cable can be and I found out
from one of the people that a length of 50CM (my original plan). Was too
long so now I have to devise a solution...
My other problem is that I don't know what the f-number aught to be.
My original idea for using the camera is this:

      lid   |
Lens Camera |
     lid    |
     screen
     screen
     screen
     ~~~~~~
     screen
     screen
     screen
      Hinge-casing-casing~~~~~~casing

Then I would simple flip the camera over the top and then I could have it
face me and do video conferencing or whatever.

Anyone have experience with this?

Thanks,
David
