One of the benefits of digital communications that we take for granted is the (optional) notification of new messages. Postifier brings what many have a love-hate relationship with to physical mailboxes via a Bluetooth-Arduino mashup. While there’s an element of “because we can” to the product, the creators appeal to the utility for those who have a hard time getting around having to go down to the driveway to pick up their mail. Another option would be to ask neighbors to pick up mail when one is on vacation. However, the Postifier uses Bluetooth, so notification is confined to a relatively short range for now. On theo other hand, the battery is expected to last around nine months. It’s not much to look at now, but should be available to backers in June 2014 for $35 AUD plus another $10 for shipping outside of Australia.
