Max and Jessica are chatting.
Max: You know how Paul has a hard time with the kegerator having a leak somewhere in the beer line? For xmas, I'll get him a liquid detector.
It will be hooked up to an Arduino mini computer with wifi. Comes with a cool app to notify your phone when it detects any moisture.
I'll also add a signal enhancer so that the wifi works through the thick kegerator walls, plus an extra battery pack that will last 5 years.
Jessica: Cool. I'll just get him a new beer line.
