Still finishing up the code. It's a simple web page so any device with a web browser will do. I'm using an old 1st gen iPad that will hang on the wall above the kegerator.

Realize "the heat" is only boiling wort. Even your laminate should be able to handle 212F. A better reason to insulate the bottom is to minimize heat loss.
