Vacation project: an E-Ink display becomes a family calendar

An E-Ink display with an ESP32 is meant to become an automatic family calendar on vacation: events and birthdays via CalDAV and CardDAV, with an AI agent.

Small vacation project: will my AI coding agent and I manage to upgrade this into an automatic family calendar?

It’s an E-Ink display with a built-in ESP32 microcontroller, so it’s fully programmable. A small but nice product, and not all that complex 😉

My goal is to automatically pull certain tagged events and birthdays via CalDAV and CardDAV. A weather display would be nice too.

But first, off for a hike 🥾
