Build the world’s smartest backpack
Concept: Companion is a backpack I built to help me get navigate through the city without having to look at my smartphone. The prototype works by sending data from my phone to the backpack, which in turns indicates me which way to go by vibrating accordingly.
Build: Companion first prototype was built entirely using an ESP8266 chip and a few other things I can not reveal. The second version is now using bluetooth to send data back and forth between the nodes and smartphone.
Result: This project has been consuming my free time for the past few months but I’m quite happy with what it has become. check www.companionbackpack.com for more informations and updates.
