Has anyone here experience building a (digital) video recorder? I want to
build a video recorder that can work on a 12V supply and is portable enough
to fit on a robot. Is there anyone here that has ever tried to build such an
apparatus or perhaps someone knows were I can find usefull info on how to
build one?

You could run a pc104 or other suitable embedded board, with a hard
disk and a capture device (usb, pci or whatever) - run linux and
ffmpeg to write the video to the disk. Simple but effective, you could
write a nice interface to it so it can be controlled with simple
buttons etc.

I have worked with Arcom embedded boards ( -
specifically the GX1 which comes loaded with a linux distro.
I got this working with a 'belkin usbvision' usb capture device, nice
and cheap - for streaming network video (using our own protocols).

No one makes one and I haven't seen a schematic for one either.

Mitsubishi nearly made something along the lines you were after, (or
it was just a test), but this was a recycling mini digi video in the
event of a car accident. (Hit something and the cycle stops). It is
about 5 years old and could be much improved yet no one has done taken
the time to. (It's beyond me)

There is a device called the memocam but this has camera, recorder and
a pir all built in so it's too bulky. If you find a schematic that has
a camera and flash or similar memory I'd be interested too.
