World Clock (highly accurate, automatically adjusted)
thingiverse
This World Clock shows 4 timezones, always accurate, always automatically switched to the right daylight saving times. Time is taken from internet NTP servers and calculated for the different locations. LDR sensor takes care of the right brightness, The radar movement sensor switches on when someone is around and off if no more movement within 2 minutes. I added the Fusion source files if you want to change the locations on the front panel. Code is found here: https://github.com/3KUdelta/ESP8266-World-Clock There is also a smaller brother of this: https://www.thingiverse.com/thing:4789713
