New E-Ink Product: Customized Daily Front Page Hyepaper──An interesting idea of E-Ink combined with ChatGPT

As we move towards the era of AI, how people use their creativity to use new tools will be an important homework.

Software engineer Eike Hein used OpenAI's ChatGPT large-scale language model (LLM) to create a custom newspaper displayed on an automatically updated E Ink panel photo frame (13.3 inches, 1600× 1200, 150PPI). Creator Hein explains: "Hyepaper is an auto-updating newspaper in a photo frame, intended as a decoration, which wakes up from deep sleep once a day to fetch and update a new newspaper image."

For this ePaper project, Hein used OpenAI's ChatGPT service to summarize text from multiple configurable news sources. It targets some of his and his wife's favorite sites, trimming articles via the ChatGPT API to make them smaller, unifying their style, and generating appropriately short headlines for layout. It also fetches the weather forecast from the OpenWeatherMap API, and this information is displayed in the upper right corner of the header—the layout of this display is inspired by the front page of the New York Times. With this content, the result looks and reads like a newspaper, including black fonts, images and formatting, but completely customized.

Hyepaper adopts intelligent power processing technology, including 5V relay to prevent virtual power exhaustion caused by E-ink display driver and real-time clock, which wakes up the ESP32 chip when a new home page needs to be drawn, so that the entire front-end device can be offline for several weeks run.
