McMahon - I don't have easy access to an electronics shop, so If possible I prefer to use the few components I already have. But as you pointed out, I may just have to replace the components.

comment Help with a simple comparator circuit
It is a single supply op-amp (LM324), and I could change the supply to 5v if needed, but the thermistor I have goes from 20 to around 80 ohms, and the pot from 0 to 500, so I had to choose a 20 ohm resistor to contrast..
