A Wall Mounted Newspaper That’s Extra

Aug 12, 2023 - hackaday.com
The article discusses a project by [Sho] that uses a 13.3 inch ED133UT2 1600×1200 E-Ink display to create a wall-mounted newspaper. The display is controlled by an ESP32 and uses an ITE IT8951 electronic paper display (EPD) driver. The device is powered by a 3.7V 1100mAh LiPo battery, with a KY-019 5V relay module used to avoid unnecessary power draw. A real-time clock is used to wake up the ESP32 and other devices for daily refreshes.

The backend software uses the OpenWeatherMap API for daily weather reports and scrapes news websites. The information is then summarized using the OpenAI ChatGPT API. Text is formatted using LuaTeX, Ghostscript, ImageMagick, and other scripts to create the final displayed graphics, which include newspaper texture and randomly placed coffee stain effects.
