Envisioned as a tool to keep Internet-connected devices up and running should the Internet go down completely, this Off-Grid Cyberdeck is an impressive feat of DIY engineering. Electronics enthusiast Jay Doscher based the computer off the Raspberry Pi 4, with an official Raspberry Pi 7" screen. It has an array of connectors for diagnosing issues, including Ethernet, USB, and Mil-Spec panel and cable options. The entire unit is held together with 3D-printed parts, sits inside a water-resistant Pelican case, and is finished off with locking switches, an internal battery, and a Plaid ortholinear keyboard.
