Introduction
Shiura on thingiverse designed a fascinating hollow clock.
The original is controlled by an Arduino. The firmware here was adapted to an ESP8266 and for the use of the WTA-timeservice instead of NTP. So there normally are no firmware-modifications necessary to adapt the timezone and DST because they will be investigated out of the public IP of the request. For special cases (f.e. the use of a foreign proxy server) the timezone can be selected manually by replacing "ip" with the wished timezone in WTAClient.cpp.
Used libraries:
- ArduinoJson
- DNSServer
- DoubleResetDetector
- ESP8266HTTPClient
- ESP8266WebServer
- ESP8266WiFi
- WiFiManager
Some modified mechanic parts are described here
