Open Book Touch: Open-Source E-Reader Hits Crowdfunding
Original: Open Book Touch: open-source e-reader
Why This Matters
Demonstrates growing market demand for privacy-focused, open-source reading hardware alternatives.
Oddly Specific Objects launched Open Book Touch on Crowd Supply, an open-source e-reader featuring a 4.26-inch front-lit e-paper touchscreen. The campaign surpassed its $45,000 goal, raising $46,542 from 241 backers with 33 days remaining. Funding closes August 20, 2026.
Open Book Touch is a fully open-source e-reader six years in development by Oddly Specific Objects. The device features a 4.26-inch front-lit e-paper touchscreen at 480×800 pixels, is 1 cm thin, and has no physical front buttons. It runs on an ESP-IDF/FreeRTOS microcontroller — not Linux — booting directly into the last-read book and drawing under one milliampere during reading. The device reads EPUB and plain text files from a microSD card and includes a full typesetting engine with justified text, proper hyphenation (English, Spanish, French, Italian), and inline image rendering. Fonts are bitmap versions of Lucida Bright and Lucida Sans, open-sourced by Sun Microsystems in 1989. Wi-Fi is included strictly for time syncing and book downloads. Features include tap-and-hold highlights, word lookup, dog-ear bookmarking, and shelf organization. Both hardware and software are fully open source. Pricing ranges from $149 to $249. The campaign is live on Crowd Supply through August 20, 2026.
