I'm taking the lazy approach again and not do a laborous search....
What's the fav cheapo electronic temp tool these days?
Smelling my own skin oil burning on electronic components is not a good way for me to gauge heat.
I'll guess:1)Thermocouple plugged into a DMM 2)Off the shelf infrared thermometer 3)Maybe there's a sleek electronic thermometer the size of a pen.
Here's my scratched ideas1)Aquarium temp strip 2)I vaguely recall a infrared camera project using a web cam 3)Also, long ago I think I came across a coating that changes color with heat. Or was it a coating that would smoke before max max junction temperature was reached. Don't know anymore.. 4) Using a finger...pain tolerance I'm guessing is at about 50C. D
