Sometimes, even the oldest cliches can serve as inspiration. Take the dog and the letter carrier, for instance: when Manuel Masri first moved to the United States, he was surprised to find his canine companion obsessed with the mailman. Every delivery became an event, anticipation for a 4pm delivery and an excited pooch -- but the K-9 notification system only worked when he was at home. His solution? Mr. Postman, a mailbox that knows when to expect your mail, notifies you when it arrives and locks after delivery.
Masri's smart mailbox falls into that growing category of the "internet of things," something that links typically disconnected physical objects with each other and your digital world. It also happens to be one of Engadget Expand's Insert Coin semi-finalists. We dropped by the company's show booth to see the project's take on the future of mail delivery.
