    Is it possible to build a cheap temperature controller for soldering irons? What parts would be needed ? I have several soldering irons the lowest is a 15watt the highest is a 60watt and all are the pencil type. I would like to use it as part of a soldering station.:D

    It's not trivial. Probably cheaper to go out and buy one. I recall I have one that cost me under $50 on special.

    Just put a thermistor on your heating element,which will be measuring the temp and use a amplifier to amplify the signals,now u have a analog voltage ( 0 to 5V).
    now u need to calibrate your thermistor,please refer to the datasheet for details.
