This is one of the coolest things I’ve seen and something Fallout fans would probably geek out for. Check out YouTuber MyMagicPudding’s homemade functioning POP-Boy 3000 replica prototype. It comes equipped with working dial and screen.

According to MyMagicPudding:

It consists of an HTC Desire HD as the screen and processor, and an Arduino Uno with a USB host shield running microbridge to act as an ADB host for the phone. The Arduino then sends button presses to the phone via TCP over USB.

The only shame is that it isn’t wearable.
