• •Brainux enables a mainline Linux kernel to function on Sharp Brain PW-series electronic dictionaries.
• •The project successfully implements screen, keyboard, and storage drivers on proprietary Sharp hardware.
• •Hardware support remains incomplete, with uncertainty surrounding advanced power management and long-term stability for daily use.

The Brainux project has released a custom implementation of the Linux kernel designed to run on the hardware of Sharp Brain electronic dictionaries. While Sharp’s devices are typically restricted to their factory OS, this project opens the devices to third-party software development. Porting efforts remain in the early stages, however, as the community is still working to map proprietary hardware registers and stabilize core peripherals. The project’s success could extend the usable life of these devices for users who prefer custom productivity environments.
