I am getting together the parts for a Son of Fermentation chiller. I found most of what I need around my workshop. I only need a sheet of 2" foam.
My question is how do I determine which wire on the DC power supply is the + one and which is the negative one. The cord has one side which is smooth and the other side is ribbed. Which is which?
I have beem unsing a swamp cooler but if I can put together a SOF for cheap then I want to give it a try.
