Coffee is the drink that keeps many people going throughout the day. Unfortunately, when you arrive home, or at the office to find that no one else has started a pot, it can be frustrating. So why not make sure that there is a fresh pot waiting for you by triggering it in advance? Since you don’t always know when you’ll be arriving, this takes a bit of clever hacking.
This Tweet-a-Pot is a hack that allows you to send a tweet that your coffee pot will recognize (it looks for a specific hash tag) and the pot will start brewing. You’ll need an Arduino, a special power plug and a computer to pull it off. If this sounds like something you must have, you can find full instructions over at Instructables.
