I am wondering if it seems possible, even pretty traight forward and easy, to your minds to control the temps on a keezer with a simple setup like this:
digital controller (like that used for your furnace) hooked up to PID that sends power to the freezer.
Is this totally off base? I'm not an electronics guru, or even particularly adept at more complex electrical interactions, but this seems to be pretty straightforward. My only real surprise, and the reason I post this, is because I was unable to find it anywhere on the site.
