A fresh pot of coffee is never more than a tweet away with the Tweet-a-Pot. It works in much the same way that our Troll Sniffing Rat does. For that build we used a Python script to monitor our comments, and this does the same except that the script read tweets through the Twitter API. It watches for a specific hash tag (#driptwit) and when found it sends a serial command to an Arduino. The microcontroller then writes a digital pin high to actuate a relay, powering up the coffee maker.
Sure, you have to preload the pot with grounds and water, but what do you expect, automatic coffee roasting and brewing? That’s quite a bit more work.
