CPU fan - Predator mask

Radio Shack does carry a 1-1/4" square CPU fan for around $15. I just
installed one in my Predator mask. It fits into the space on the side
of the temple. I took a power cord from a hard disk, cut it in half,
soldered the "female" end onto the fan and the "male end onto two 6V
IBM AT batteries that I connected in series for 12V. I can just unplug
it, take off my mask, leave the battery pack in my shirt pocket, and
eat lunch or whatever... I didn't have a fogging problem Sat so I haven't
put it to the test, but when I breathed into it lense it seemed to clear
in a few seconds.

FYI, I have access to similar fans, I believe rated at 20 cfm,
for under $11 each.  I'll post up the full list of fans I can order.
(quite a large selection, really)  The deeper and larger, the more
CFM. (cubic feet per minute)  The "good" ones range from 1.25
to 1.825" square, and from .5 to 1" thick.  Stay tuned...
