I got the fridge for 10 bucks on craigslist. controller on Ebay for $20 then $30 in parts at Lowes and I'm good to go. I took pictures of the controller build. I took a scrap piece of plywood and mounted 2 boxes to it. I used 2 cause the fridge in in a closet type thing in the garage and i wanted it be able to see it. I've got the probe running inside and I will mount it to carboys.
