Mechanical digital clock with network time acquisition

I made this incredible simple but genius clock by shiura and found, that the parts have to be glued or welded together. Because I'm not a friend of nondetachable connections I tried to make the respective parts new from scratch to be able to mount them by simply joining them together. The ESP32 was a bit oversized for this simple job in my mind. So I designed mount positions for an ESP8266 and the stepper amplifier in the base to fix the PCB safe in the case. You see here only the modified parts. The original number cylinders you can get from the source by shiura. The firmware had to be adapted to the ESP8266 and ist available on github. To prevent the mess with timezones and daylight saving I used the WTA-API instead of the NTP-service. So your timezone can be figured out from your public IP and no firmware modification is neccessary for all timezones.

Edit 2021/08/31: added option "PRE_MOVE" in firmware for earlier start of motion to reach target position just in time

Edit 2021/10/18: added slots in the bases to hold the snap-in-tongues of the additional base-bottoms by Art_Lieberman
