Homebrew PCBs

Maybe MAX6675? Thermocouple input with built-in cold junction
compensation, 12bit ADC.

BTW, this needs to move to Electronics_101. I've posted a rough
schematic/block diagram of a potential circuit using a Silicon diode
for cold junction compensation, with a simple Wheatstone bridge
circuit to use your DMM as a thermometer, only active part is a
voltage regulator. 1mV/C.
