I'm working on a device that turns any mailbox into a smart one. If you insert my device into your mailbox, it will send you an electronic notification when mail comes in or is taken out. Currently working with a functional prototype. Thoughts?
Ross, we're launching a kickstarter campaign for such a device in 2 months, that we've been working on for over 2 years. It will have a lot more features than just alerts. Wanna learn more about it?
