First things first.
The information contained in this post is provided for informational and educational purposes only, and only intended for use by qualified electricians and electrical workers. I will not be held liable for any injury or damage to property as a result of un-qualified and DIY'ers carrying out their own un-licenced electrical work. Not only is it dangerous, but also illegal. Only suitably qualified electricians are legally able to carry out electrical work. Please do not be offended if I refuse to go into further detail to assist you in wiring this up. I do not claim this design meets applicable AS/NZ standards. It is extreamly important all electrical work is tested by a compitent person.
So, if you want a cheap, simple "PSR-25 style" heat controller for your still and know a sparky that can piece it together and test it, here is how to make one.
Purchase one of these relays depending on the size of your still;

If the relay you select does not come with a Heat sink, purchase one of these 2;

Purchase the following Voltmeter;

Purchase a Type B linear 3pin potentiometer that meets the requirements of your selected relay, you will find one between Uxcell and ebay cheap.
Purchase some thermal compound (heat sink goo) from ebay to smear between the the heat sink and relay. I got 3 syringes for $1 and only needed half a syringe.
Put together as shown;
