Super cool, great work! Looks like it could be in the MOMA

Awesome!!! Is there any way the 3D designs are available somewhere?

[@stefanwild1512]

Thanks! I'm sorry, is not available.

Great design ！ Does the HALL sensor detect the minute hand and the hour hand respectively? Or just detect the minute hand?

[@stefanwild1512]

Thanks 😊! There are two Hall-Sensors. The one for the hour-wheel ist at the same position but not visible in the video. It detects the magnet of the hour-pointer at the 5 o'clock position. The advantage of two Hall-Sensors: after reset or power fail, the mechanics adjust the correct time itself.

@@stefanwild1512 Mechanics can adjust the correct time itself is very import!! Can you show the Tinkercad file and code ? I want to try to make it using ESP32 by NTP.
