Open Book Touch is a compact, DIY-friendly e-reader designed for people who want more control over their tech. Built around an open architecture and outfitted with physical buttons, it focuses on reading first while giving tinkerers the freedom to customize almost every part of the experience.
Unlike many e-ink devices that try to be full-fledged tablets, this model embraces minimalism without feeling bare-bones. It’s powered by the ESP32-S3, a widely used microcontroller with integrated Wi-Fi and Bluetooth—more than capable for smooth page turns, library browsing, and simple extras. Because it’s programmable via Arduino and CircuitPython, you can tailor the interface, add features, and connect it to your own projects, from custom note-taking workflows to cloud sync scripts.
The device is headed to market through a CrowdSupply campaign, with pricing yet to be announced. What’s clear is the emphasis on portability and comfort: it’s small, lightweight, and includes a front light that supports both cool and warm tones, making it easy on the eyes day or night.
