Pseudonymous maker "snc" has released 3D print files and instructions for building your own YARH.IO M4 β a handheld cyberdeck powered by a Raspberry Pi 4 Model B. This device features a desk stand, active cooling, and integrated charging capabilities.
"Two years ago I posted the YARH.IO M4 as a WIP [Work-In-Progress]," snc writes of the project, the third generation in a family of DIY cyberdeck builds. "It took me a while, but I finally put everything together and published the full build documentation, parts list, assembly guide, and STL files on yarh.io. The M4 is a Raspberry Pi 4B handheld running the i3 window manager with an adjustable 3D-printed stand. The STL files cover both Raspberry Pi 4 and Pi 3 variants."
Known at launch as the YARH.IO Micro 4, the M4 is a compact handheld dictated by the Raspberry Pi 4 Model B that powers it. It includes a full-color 4.3" touchscreen and a Bluetooth keyboard. Full access to the Raspberry Pi 4's USB ports means you can easily connect an external keyboard when using the optional desktop stand.
The device features active cooling with vents in the 3D-printed case. Below the Raspberry Pi, a step-up voltage regulator for a lithium battery is installed. "The i3status bar picks up this data and displays battery level, CPU usage, and network status," snc explains.
While the YARH.IO M4 was first unveiled two years ago, it's only now possible to build your own. snc has released the source code for the battery daemon and 3D print STL files for both the case and desktop stand. "It's a great way to give new life to an old Raspberry Pi 3 or 3A+," the maker notes.
