the cooling is needed due to the CCD property of capturing not only
light but also heat. in long exposures they may get moisty.
that property explains why we have so many CCD cameras with night shot
around.

"monkeying around with equipment", as William EricKson said, may violate
the orthodox pinholing life but, IMHO, excluding the digital world from
imaging and pinhole photography is to live in a cave without coming out
to enjoy the trees (although looking from inside of a cave is the
fundamental pinhole experience).

btw. I tried the scan experience but it will only work with a
transparency adapter so the software may be fooled and will turn the
scanner's light off and read the projected light from the pinhole.
