Daniel Nguyen open-sourced Inka, a pen-first AI journal app for BOOX e-ink tablets. It allows users to write with a stylus and receive AI-generated handwritten replies on the page, using their own API key.
The author successfully implemented a playable Gameboy emulator on the M5 Paper S3 (ESP32 S3 + e-ink display). By using high refresh rate driving, an optimized emulation core, and an innovative pseudo-polyphonic sound scheme, classic games run smoothly on the e-ink screen.
