A little more detail, the lights and fans are driven by a reed switch and several SSRs so that they turn off when the lid opens, and an overhead light turns on so i can see what im doing.
The lid is pretty heavy, but it is supported and operated by a linear actuator (lifts 400lbs!)
Temp control is located in the back of the tap box (love controls) and the probe is in the whitelabs yeast tube. I put vodka in the tube so it doesnt mold or freeze.
The bottom mat i put in so that the kegs dont sit in water if there is any condensation. there is also a drain solenoid that will allow me to drain the bottom without having to fumble around in the bottom.
