It combines a 2.9-inch e-paper screen, rotary encoder and RGB mood light, with an estimated 20 hours of use per charge. On first boot, users configure Wi-Fi through a captive portal; once online, the device contacts Gemini to generate a story. The excerpt notes that a library of human-written stories could be an alternative, but does not describe that functionality as implemented. ### Source excerpt Choose your own adventure books were one of the first media to become gamified in the computer era, and [Jeremy Ngai] wanted to bridge the experience further with an e-paper ...read more ## Build Your Own E-Reader for $40 DevFeed: [Build Your Own E-Reader for $40]() Original publisher: [Read original article]() Author: Ben Published: 2026-11-07T21:03:06Z Content type: tutorial Language: en Sources: [Adafruit Industries]() Topics: [Learning](), [MicroPython]() Tags: [adapter](), [board](), [build](), [bus](), [button](), [dev](), [e-ink](), [e-paper](), [e-reader](), [esp32](), [esp32-s3](), [flash](), [gpio](), [guide](), [how-tos](), [microcontroller](), [module](), [navigation](), [optional](), [panel](), [power]() ### AI overview The build uses an ESP32-S3 dev board, an e-paper panel and adapter, a five-way button module, and a power source; the excerpt estimates total cost at $35-$60, depending on the panel. The ESP32-S3 is chosen for built-in Wi-Fi, flash for storing books, and hardware SPI to drive the display. Boards with 8 MB or 16 MB flash are recommended in the source; 4 MB can work but leaves little room for text. The buttons connect through a shared ground and five GPIO signal pins. A BME280 sensor is an optional add-on for temperature and humidity on the status line. ### Source excerpt Allan Binder of MUON SORTES shares this how to guide for building an affordable e-reader. And head to Allan Binder's instagram for a more polished look and future iterations.

Both are 800x480 and use a 2,000 mAh battery. The 4.26-inch Mono supports partial refresh in black-and-white mode and an optional four-gray mode; the 7.3-inch Spectra 6 Color uses a fixed six-color palette and does not support partial refresh in color mode. Images can be sent through OpenDisplay Toolbox in Chrome or Edge, or through a compatible sender such as Home Assistant; Firefox is not supported. Home Assistant needs Bluetooth or Wi-Fi within range, with an ESPHome Bluetooth Proxy offered to extend Bluetooth coverage. The text estimates up to two years' battery life for the mono kit with 15-minute updates and one year for the color kit with two-hour updates. ### Source excerpt Seeed Studio has launched two Nordic nRF52840-based Bluetooth LE e-paper kits preloaded with the OpenDisplay open-source firmware for e-paper displays and supporting Home Assistant integration. The OpenDisplay 4.26″ Mono features a 4.26-inch monochrome/grayscale display with 800x480 resolution and partial refresh support, while the OpenDisplay 7.3″ Color Kit is equipped with a 7.3-inch Spectra 6 color e-paper with the same resolution.

Its content depends on the selected plug-in, with examples including calendars, weather, stock quotes, and lunar phases. It can run through TRMNL's service ($1 to start a 14-day trial, then a one-time $50 fee), Seeed's free SenseCraft platform and browser flasher, or a self-hosted Terminus Docker stack. The author chose self-hosting and encountered Unraid bridge networking issues, outdated shipped firmware (1.5.12 versus current 1.8.18), and a serial-port problem with the web flasher on Fedora that did not occur on a Mac. Two 3D-printable cases are available; the prism is simpler because the L-shaped case needs a ribbon-cable channel. ### Source excerpt Nick Indge, writing for Ars Technica, built out a $48 DIY e-paper kit from Seeed Studio made in partnership with TRMNL. It's a 7.5-inch e-paper panel and a control board that pings an API, pulls down a bitmap, and shows it. Calendars, weather, stock quotes, lunar phases, whatever plug-in you pick. .

The board ran a Game Boy emulator with a custom display driver, and power draw was measured in idle, emulation, and continuous-update gameplay states. To check for permanent marks from the unusually frequent refreshes, the panel was run at 30 FPS for about 20 hours. The driver and emulator are published as InkBoy; the excerpt does not give the test's measured power figures or durability results. ### Source excerpt Bo Made It measured what it costs to push an e-paper display far past its normal refresh rate, in a video published on YouTube. The test board is the Waveshare ESP32-S3-ePaper, running a custom display driver and a Game Boy emulator at 30 frames per second.

The excerpt reports that a datasheet's typical one-million-update lifespan would amount to about 9.3 hours at 30 FPS if every frame required a full refresh. In a custom test after 2.16 million frames, some ghosting appeared but cleared with repeated refreshing; no permanent damage had been detected. The test is not conclusive about long-term wear: smart drivers update changed pixels, so refresh counts may differ, and Waveshare recommends against high-FPS use. Damage from such use would not be covered by warranty. ### Source excerpt Although e-paper displays are famous for being low-power and lasting essentially forever if not damaged physically, the recent push to drive even cheaper e-paper displays at a framerate like 30 ...read more ## Practice Japanese on an Inkplate 4Tempera eInk device, open source DevFeed: [Practice Japanese on an Inkplate 4Tempera eInk device, open source]() Original publisher: [Read original article]() Author: Anne Barela Published: 2026-10-28T19:03:08Z Content type: article Language: en Sources: [Adafruit Industries]() Topics: [Open Source](), [Documentation](), [Esp32 C2]() Tags: [calendar](), [card](), [code](), [device](), [documentation](), [e-paper](), [education](), [eink](), [esp32](), [firmware](), [flash](), [github](), [hardware](), [ics](), [import](), [inkplate](), [japanese](), [macos](), [mit](), [open-source](), [published](), [scheduler](), [software](), [temperature]() ### AI overview Enkiplate is an open-source Japanese flashcard system for the Soldered Inkplate 4TEMPERA: read a card, tap to reveal its answer, and rate your recall while a scheduler tracks what needs practice. The screen also shows the day's temperature range and next three calendar events. A host companion service renders text and paper textures into 3-bit frames and sends them over WiFi or USB. Setup imports common vocabulary from JMdict; users can also add vocabulary or short sentences and check their fit on the paper layout. Weather uses Open-Meteo, and calendar data comes from a private .ics feed, excluding all-day and cancelled events. The tested host is macOS; Windows is unsupported, and other Inkplate models require a firmware port. The code is MIT licensed, while fonts and dictionary data have separate terms. ### Source excerpt Peter Hraska built Enkiplate, a Japanese flashcard system for the Soldered Inkplate 4TEMPERA, and published the code and documentation on GitHub.
