A vacation project gone astray

Instead of family events, the e-ink display suddenly shows webinar dates. Between microcontroller quirks, calendar APIs and rain jackets on vacation.

A vacation project gone astray? Instead of family appointments, the e-ink display now shows exciting webinar dates. What on earth went wrong? 😉

I brought the ESP32-based gadget along on vacation to turn it into a proper family calendar on rainy days (like today). With the help of my trusted AI coding agent, of course.

Since then, we’ve been wrestling with microcontroller quirks and calendar APIs. And by now I’m sure: this is going to work 💪🏻

But a quick shout-out to my colleagues Benjamin Zimmer and Zacharias Sitter, who must be in the final stretch of preparing their webinar, simply has to be part of this too!

I know first-hand that the session is worth attending for anyone in the PLM space asking themselves right now: “AI has potential, but where exactly in our case?” And perhaps in highly heterogeneous IT architectures with distributed data on top of that. Sign up here

All right, enough for today. Where are the rain jackets? 🌧️
