The gadget appearing in Fallout 3 and Fallout: New Vegas came to live.
In the game, Pip-Boy 3000 is an electronic Personal Information Processor (PIP) produced by RobCo Industries in the mid-21st century. It acts as the HUD in the game. Now one geek has built a real-life version, minus the in-game functionality.
Powered by Rasberry Pi, it does feature the PipBoy operating system and can even grab location data if you have a Google Maps API key.
