Raspberry Pi, Untethered.
CutiePi is a Raspberry Pi 4 tablet that turns your project into an untethered adventure. Build and create wherever an idea strikes you. No wires, no external power, and no strings attached.
A Homebrew Retro-style Handheld PC.
The Penkēsu (Japanese: ペンケース) is a retro-style handheld device powered by a Raspberry Pi Zero 2 W, a 7.9 inch widescreen display (1280 x 400 resolution), and a 48-key ortholinear mechanical keyboard.
Laptop producer focused on fixability.

ShredOS is a USB bootable (BIOS or UEFI) small linux distribution with the sole purpose of securely erasing the entire contents of your disks using the program nwipe. If you are familiar with dwipe from DBAN then you will feel right at home with ShredOS and nwipe. What are the advantages of nwipe over dwipe/DBAN? Well as everybody probably knows, DBAN development stopped in 2015 which means it has not received any further bug fixes or support for new hardware since that date. Nwipe originally was a fork of dwipe but has continued to have improvements and bug fixes and is now available in many Linux distros. ShredOS hopefully will always provide the latest nwipe on a up to date Linux kernel so it will support modern hardware.
PULPino is an open-source microcontroller system, based on a small 32-bit RISC-V core developed at ETH Zurich. The core has an IPC close to 1, full support for the base integer instruction set (RV32I), compressed instructions (RV32C) and partial support for the multiplication instruction set extension (RV32M). It implements several ISA extensions such as: hardware loops, post-incrementing load and store instructions, ALU and MAC operations, which increase the efficiency of the core in low-power signal processing applications.
OpenSesame is a device that can wirelessly open virtually any fixed-code garage door in seconds, exploiting a new attack I've discovered on wireless fixed-pin devices. Using a child's toy from Mattel.
If you spent three years building an operating system for emerging markets, what would it look like? It would be as simple as a tablet. It would have apps for the things people care about most, like education, health and livelihood. It would work well without an internet connection. At its core, it would understand that lives in emerging markets are unique, and that technology there should be too. This is Endless.
