Reflective LCD Slabtop Terminal Runs Homebrewed Solar OS

A developer built a slabtop terminal using a Waveshare ESP32-S3-RLCD-4.2 board with a reflective LCD, mini keyboard, and 3D printed case. The device runs Solar OS, a homebrewed operating system based on FreeRTOS and ESP-IDE. The system supports Python and Lua scripting, includes apps like a web browser and file manager, and uses an SD card for storage.
