Better CMUcam2 Mount

[Kevin Sevcik]

I think the main issue it that, while a ribbon cable would bend pretty easily in the up-down direction. But getting it to twist so you can do the panning motion.. I think that would be a good bit more difficult.

I suppose that problem depends on the way the cable (and, indeed, the mount) is done. You could just give the cable enough slack to twist easily when the camera pans, then use a bit of force to keep it from flapping in the breese (a la 233 this year with the wires to their grabber--load the high-res and look at the front side of the arm). Alternatively, if the main goal is just to give the main board some breathing room, why not mount the board so it pans as well? I don't think there's anything stopping you from mounting the board to the back of the IFI mount, or there's always doing what WildStang did in 2006 (according to the Behind the Design book) and using a turret to handle that part of the problem. Command the turret to move, and board and lens move happily together.

(Now, watch--someone's going to come along with a 32-pin cable that can be twisted all day. I suppose that four Cat5 cables together would do the trick, even if it'd be particularly heavy and time-consuming for the task.)

Did you see this?

I didn't see it until AFTER we shipped this year...we might check it out next time.

didn't see this until just now...but it should be easy to make ribbon cable bend both directions, if you just fold the cable over at a 45 degree angle, like they used to do on the original IBM PC floppy drive cables. (showing my age again)
