I usually use my fingers for that sort of test. :)
Warning. Don't try it on really hot chips! I have a small lump on my thumb
leftover from touching a chip that was trying to self-destruct. (bus clash)
Does anybody know of a low cost camera that works in IR? I expect somebody
probably makes a slightly modified version of one of the USB cameras for just
this sort of work.
I found this while poking around. How to modify your webcam:
Basically, take it apart, remove IR filter, add visible filter (old slide
film), put it back together.
These are my opinions, not necessarily my employer's. I hate spam.
