Nate Welch over at Arkatechture (bet that’s nice to have to spell every time! ;-)) has blogged about some integration they’ve done between instant messenger app Slack and one of their Raspberry Pis. The Pi is hooked up to sensors that detect when fresh coffee or popcorn is made and then uses the Slack API to generate a memo which is posted to everyone in the Slack group. The code is available on GitHub and you can read more on their blog.
