Summary

Just another seven segment LED clock.
Current version of SW working, but it isn't final version.
What is working:

time on dislpay
synchronization from NTP server
time in local time zone. This zone must be specified manually on source code like "Europe/Prague". See https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
extreme simple web interface to allow select LED color and brightest.
connect to internet over WiFi. Network name and password must be specified manually in source code.
ambient light sensor and automatic brightest control.(need APDS-9960 light sensor module)
local RTC suport as clock source backup (need RTC module based on DS3231)

Features in todo list:

show temperature from internet connected weather station
better web configuration
user friendly WiFi setting

It is almost fully parametric OpenSCAD design. Generated STLs are for 110mm digits, but you can create size as you want to have.
