Wow, twice in the last month I have had articles on hot topics in 
Sci.electornics.  (The first was an article about electrostatic sensors
for rc-planes).  Anyway, about building an infrared viewing system.

There was an article on this subject way back in the mid-70's in one
of the popular electronics magizine.  (The photocopy I have doesn't
have the date on it, but it was written by Forrest Mims.)  It describes
how to build an infrared viewing system for $35.  The major part of the
system is a 6032 or 6929 image tube.  In the mid 70's, I was able to
order one for about $13, and as late as the early 80's, the tubes were
still being advertised.  Unfortunately, I gave my tube away.  These 
tubes required between 12kV and 20kV, which is why I didn't want to 
get to close to them.
