The Finders Keepers is a backpack that keeps track of the pencils, calculators, and other common objects and alerts users when those objects are not returned to their spots. The backpack has small rectangular tubes tucked in the pencil pockets that detect whether a pencil is in them or not, as well as multiple other compartments for multiple other objects. The tubes and compartments are connected to a Particle Photon microcontroller that is able to light up an LED, set off a buzzer, or even send a text to a user’s phone in order to notify them that one of the items in the backpack is missing. The Photon is connected to a battery pack that, when placed on a Smart Charging Mat, is able to wirelessly charge. The Finders Keepers makes sure users don’t have to worry about remembering their stuff.
