A friend has lent me a dedicated Flir camera and I thought it would be 
great for doing exactly the above. The problem is it is an older one 
that takes up to five minutes to stabilize and by then I've usually 
found the problem...

It was nice trying it on an Atari pinball MPU that some idiot had 
plugged in the solenoid connector to the switch jack. The fifteen or so 
blown ICs stood out easily against the background!

What is interesting is that a number of digital cameras will work in the 
IR range, so I've thought of getting a visible light filter whenever I 
again order some lens from Edmonds to play with some of my cameras to 
see how far they actually see. I have used camera phones for checking IR 
diodes (including laser diodes on CD players) and the older iPhones 
worked for that - which was handy for troubleshooting trough optos.
