Is there a way of creating a *CHEAP* video digitizer with a pic? I
would also be interested in knowing if there are plans for this, or
plans for a video digitizer without a PIC inot. I would appreciate
any help.

The cheapest video digitizer I know of is called DCFG, or Dirt Cheap Frame
Grabber. It uses a 339 comparator and a couple of diodes and transistors
and a few resistors. No PIC. You ought to be able to find it if you do a
search for its name. Gray-scale, with a depth of almost 4 bits(12 levels of
gray).

The resolution is not great, but it's real-time(15fps) and it comes with
source(in turbo pascal) and if you have a good computer and can run the isa
bus clock fast(it hooks to the printer port, whose maximum speed is
ultimately dependent on the isa bus speed) you can get higher resolution if
you modify the source a little and recompile the program.

That's about as simple as it gets!
