Twitter + Door = Door++

Twitter + Door = Door++

Jan 12

StudentRND has a new lock thanks to Adam Ryman! This new lock is awesome. And "awesome" is not a word I often use for locks. Our new lock opens when 12V is applied across its leads.

Naturally, I hooked it up to an Arduino. And I hooked that Arduino up to the internet.

So now we have a door lock which listens to @srnddoor on Twitter, and replies to requests from authorized users to open the door. (And, thanks to Twitter's streaming API, this is near real-time; it's literally less than a second from when I hit send on my phone to when the door opens.) Locked out no more, plus we have much better access control!

(Props for inspiration to Github's Hubot, which unlocked the door when asked on their Campfire.)
