Diptyx E-Reader – An open-source, ESP32-powered, dual-screen e-book reader (Crowdfunding)

There are plenty of e-book readers on the market, but the Diptyx E-Reader feels more like a proper book since it features two e-paper displays that can be folded or opened thanks to a custom-made plastic enclosure. While it’s powered by an ESP32-S3 wireless module with a PCB antenna, both WiFi and Bluetooth are disabled in the firmware, and instead, users can load EPUB files through the reader’s USB Type-C port. The combination of an automatic standby mode (using deep sleep) and e-ink displays enables the dual-screen device to run for weeks on a single charge. Two buttons are used to access the next or previous page, and a third one powers the device up in a few seconds. Diptyx E-Reader specifications: Wireless module – ESP32-S3-WROOM-1 SoC – Espressif Systems ESP32-S3-N16R8 CPU – ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension Memory – 8MB PSRAM Storage – […]

FOSDEM 2024 schedule – Open-source embedded, mobile, IoT, robotics, RISC-V, etc..

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where thousands of developers meet in Brussels on the first week-end of February to discuss open-source software & hardware projects. FOSDEM 2024 will take place on February 3-4 with 880 speakers, 818 events, and 66 tracks. Although I won’t attend, I’ve created a virtual schedule like every year with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms including “FOSS Mobile Devices”, “ Energy: Reimagining this Ecosystem through Open Source”, “RISC-V”, and others. FOSDEM Day 1 – Saturday, February 3, 2024 10:30 – 10:55 – Screen Sharing on Raspberry Pi 5 Using VNC in Weston and Wayland with the Yocto Project and OpenEmbedded by Leon Anavi In 2023, embedded Linux developers received eagerly awaited news: […]

PineNote Developer Edition mainline Linux e-Reader is now available for $399

Pine64 community has been on a tear in 2022, with the launch of the PineNote Developer Edition Linux e-reader following the availability of the PinePhone keyboard case and PinePhone Pro Explorer Edition Linux smartphone in the last 2-3 weeks. So far a limited number of PineNote prototypes had been sent to developers, but it’s now possible to order the PineNote Developer Edition for $399 directly on the Pine64 store. As its name implies, the e-Reader is not ready for end-users, but recent progress with mainline Linux makes it suitable for developers and enthusiasts who want to play around with the device knowing much more work is needed to make it a usable device. The specifications remain the same as in the initial PineNote announcement: SoC – Rockchip RK3566 quad-core A55 processor @ 1.8 GHz with Arm Mali-G52 EE GPU, 0.8 TOPS NPU (AI accelerator) System Memory – 4GB of LPDDR4 […]

PineNote is a community supported 10.3-inch e-Reader based on Rockchip RK3566 SoC

We’ve covered several e-readers in the past, but the PineNote 10.3-inch e-reader will be a bit different, as the hardware & software will be entirely developed by the community like other Pine64 platforms such as Pinebook Pro, PineCone, Rock64 single board computer, etc… Based on the Rockchip RK3566 quad-core Cortex-A55 processor, PineNote will be one of the fastest e-readers on the market, and leverage the code already written for Quartz64 single board computer, including mainline Linux support. PineNote (preliminary) specifications: SoC – Rockchip RK3566 quad-core A55 processor with Mali-G52 EE GPU, 0.8 TOPS NPU (AI accelerator) System Memory – 4GB of LPDDR4 RAM Storage – 128GB eMMC flash Display – 10.3-inch panel with 1404×1872 resolution (227 DPI), 16 levels of grayscale, front light with cool (white) to warm (amber) light adjustment, capacitive glass layer for finger touch-based input, and a Wacom electromagnetic resonance layer (EMR) for EMR pen input. There’s […]

DIY Linux e-Reader – postmarketOS now runs on Kobo Clara HD

postmarketOS is a Linux operating system designed for phones, notably the PinePhone, and based on Alpine Linux. But now it’s possible to install the Linux distribution on Kobo Clara HD e-Reader (about $115), so you could have your own Linux e-Reader in a way that’s more versatile than with commercial solutions. The image can either be based on the vendor kernel or the mainline kernel. The latter works without modification to the X server, and the framebuffer can be used directly with either kernel, but most free e-reader programs such as koreader, plato, and inkbox are developed for the slightly different framebuffer API used in the vendor kernel. The demo below relies on Sxmo UI optimized for the PinePhone, and Martijn Braam notes that it can be pretty hard notably because only one hardware button is present on the Kobo device while the interface requires 3 hardware input buttons. But […]
