For the NASA Space Apps Challenge a team of five people built a working Pip-Boy 3000 from Fallout 3!
A 3D printed case holds an iPhone 5 in place and runs an iOS app. Together with two microcontrollers which are connected via BLE4 and a REST API their system is capable of displaying sensor values such as humidity, altitude, latitude, longitude, atmospheric pressure, ambient temperature, object temperature using an infared thermometer and (of course!) radiation.
The 3D model for the case was created by Dragonator who finished his replica of the Pip-Boy 3000 with a nice paintjob. He also built a laser pistol from Fallout 3.
