Hi all, I need to make a simple heater, to raise the temperature of my camera lens enough to stop it from fogging up. I have a pc fan and heat sink that I would like to use, but I'm not sure what to use as the heat source - I was thinking of using resistors but the bottom of the heat sink is smooth so it would be hard to get the heat to transfer.
Any suggestions?
