Wedding Gift (e-ink-based digital guestbook) 

This channel is really underrated! Watched al the video's. Richtig Geil! - Danke!

I always loved e-ink displays for their low power usage and this setup seems so simple. I'll certainly take a closer look into it. Thanks

This! Is so cool...well done.

Very interesting, thanks 😊

Ach, du bist der Entwickler von phy.phox. Nice channel.
