gEDA-user: DIY thermographic camera?

[Randall Nortman <geda-lists@xxxxxxxxxxxxxxx>]

Thermographic (IR) imaging cameras, such as you might use for an
energy audit on your home, are $5k+.  Could one get reasonably useful
results from a hacked camcorder or digital camera with appropriate
filters?  Absolute accuracy would not matter, but I'd want it to be
able to resolve relative temperature differences pretty well over a
range of, say, 0C - 50C.

Any thoughts?
