Hi Bryan,

I have used the Nogatech Conference Card (PCMCIA sound/video capture) with
the TechWearable, but would not recommend it. Nogatech has stopped producing
and supporting these despite the fact that they are still on the shelf in
some stores. If you are looking for high-quality/framerate video capture on
your wearable, and robot, take a look at  what is available for the
bt848/849-based capture cards. I have used several varients of these cards
(IMS Inc. Turbo TV, Hauppauge WinTV) on one of my robots and have nothing
but good things to say about them. ActivMedia Robotics sells a PC-104+
framegrabber for use with their Pioneer-2 robots that is based on this chip.
RH Linux drivers can be found at  http://robots.activmedia.com/bt8xx/

If power consumption is more important than speed/quality I would recommend
you go with a USB camera...
