Multi-monitor setups are commonplace among desktop computer users, but, with very few exceptions, manufacturers limit portable devices to just a single measly screen. There are a couple of dual-screen laptops on the market and there have been handful of cell phones with more than one screen, even going back to the dark ages of dumb phones. But Redditor Holistech must have laughed in the face of those devices when they built this crazy quad-screen Raspberry Pi cyberdeck, which is the best kind of overkill.
For the uninitiated, "cyberdecks" are custom portable computers that are loosely inspired by the works for William Gibson — namely Neuromancer and the rest of the Sprawl trilogy. They usually resemble the progeny that would result from a lusty affair between a Commodore 64 and some sort of military-grade walkie talkie. Holistech's cyberdeck takes that concept in an absurd new direction. This device does fold closed for transportation, but it does so in a manner more akin to a Transformer than a laptop. It has several hinges, so the five distinct modules of the device can collapse into a vaguely portable chunk of plastic.
Each of the four displays is a 5.5" AMOLED screen with a full HD resolution. The device contains two Raspberry Pi 4 Model B single-board computers that have 8GB of RAM, so each computer is responsible for driving two screens. Power comes from a pair of massive 26,000mAh battery power banks. Input is through a single battery-powered Bluetooth keyboard with built-in touchpad. KVM (Keyboard, Video, Mouse) software lets the user switch between the computer currently connected to the keyboard. That crazy hinged enclosure was 3D-printed in a pleasant orange and white, Creamsicle-esque color scheme.
Holistech hasn't published the 3D models for the enclosure, because they are considering selling the cases. But if there isn't much interest from buyers, they may release the files in the future. Either way, be sure to follow them if you want to get your hands on this unusual case sometime in the future.
