Rob's page on how to connect directly to TV sets, and other
useful info for which there is a
mirror site.
Portions of this info (e.g. specifics of the TV connection) is
also mirrored here on the
WearCam site
Other useful linux-related links, including Powerd (a tool
to gracefully shutdown on low battery, to avoid fsck, etc..).
For example, if you're building a small low-power wearcomp,
you can go a long way without X-windows, by using
gpm,
virtual consoles, and SVGAlib.
