i've wanted to work with a fully mobile system for a while now. I'm having trouble finding one part so far, a USB video out interface, ideally one I can run an X server with QVGA resolution on.
I am looking to pickup up an eyetop eyetop on ebay to use as an inexpensive HUD to start with.
then i'll just have to run whatever i want up all the time in the bar on the bottom.
i'll use a mini 4 port usb hub with a 5v power source to run the usb video out interface and 30 gig hd. once i get the 2.6 kernel up on it and stable i'll add usb wifi and bluetooth support also. for input i'm going to use a twidderler2.
for audio io i have a bluetooth headset i'm going to use with the sco driver, and use flite for verbal audio out, and sphinx2 for voice in, a few modifications to perlbox-voice and it should run with flite instead of festival.
but to start anything i first need a usb video out device with linux 2.4/2.6 drivers.
any other information on others trying similar projects like this please post here, i'd really like to know what other people are trying.
