This looks like a great idea1 and they're cheap as chips2, I hope that comes with a power supply. I can probably use my raspberry pi relay board with that too for a bit more control.
Will arrive too late for this home brew but an interesting thing to play with anyway. I might have to put the tumble dryer on now to perk the current brew up!
raspberry pi: Credit card sized super cheap computer, awesome.
