A Fallout fan made a Pip-Boy wrist computer with his own hands. The device is not decorative and can do some things.
Fallout fans are jealous: an engineer has built a functioning Pip-Boy from Fallout 76. The man wrote the code and interface himself, and printed the case on a 3D printer. The computer is based on Raspberry Pi.
Pip-Boy displays real air temperature with a world map and can play mp3 files.
