http://CALE.es - Web-Service Configure API Mixins with Image Output for ESP32/8266 This is a custom back case designed to work seamlessly alongside the front case of Waveshare, which comes equipped with 12 powerful magnets but remains surprisingly thin. The aim of this redesign is to create ample space for housing as many components as desired, including: - A robust 5000 mA Lion battery - TinyPICO ESP32 (courtesy of unexpected maker) - A compact 12*12 mm square push button (Reset) - A convenient USB hole [Demo video featuring an ESP8266 as controller](https://www.youtube.com/watch?v=5x-FETrisDw) If you plan to use this in your office, I would greatly appreciate a small donation to enable me to dedicate more time to working on this project. If you're interested in creating your own Google Calendar that refreshes every two hours and consumes less than 1 mA per hour in deep sleep mode, then this could be of great interest. Please follow the [CALE project on Hackaday](https://hackaday.io/project/169086-cale-low-energy-eink-wallpaper) ### If you use it for your office, please support the project by sponsoring CALE on GitHub ### The front part is coming soon! Stay tuned... Note: hat-cover-eink.obj has a minor issue at the top, but it prints out nicely. The idea behind this small piece is to attach it to the hat and create a flat surface, then glue it directly onto the back of the Eink (using transparent tape in between) #### Product list 7.5inch e-Paper Raw Panel Case https://www.waveshare.com/7.5inch-e-paper-case.htm 800×480, 7.5inch E-Ink display HAT for Raspberry Pi https://www.waveshare.com/7.5inch-e-paper-hat.htm This greatly simplifies the assembly process since otherwise you'd need to use a rather large and cumbersome cable. If you want to easily connect your Google Calendar or other APIs to your Eink screens, simply Register on cale.es and give it a try.
