First off... a possibly silly question.  Anyone out there know of any sort of   overheating problem a monitor can have that causes the screen to loose          interlace?  Instead of scanning the lines _next_ to each other, it scans them
on top of each other.  I'm reasonably sure that it is a heat related problem,
and it occurs on both the NTSC and analog RGB inputs.
Thanks for any help.

Now, regarding a cheap lo-rez video input, a mech eng friend of mine once
told me of this thing called a RAMera.... 

Warning: this is totally untried.


First of all, take a 4kX1 bit DRAM and somehow expose the silicon.  I suppsose
you could pop the top of  an old ceramic or plane the top layer off a plastic.
Anyway, fit it with a lens... and that is almost it.

To use the thing as a camera, just charge up the thing to all 1's, wait for a
bit, and then check which bits are discharged by the ambient light.

The reason you can't go above 4K is 'cause manufactures like to break up that
nice sqaure area of capacitors above that density.

Anyway, it sounded interesting.
