Description

Summary A “normal” analog clock with extraordinary brains. Inspired by the beautiful Holo Clock by ekaggrat, I wanted to add precision and intelligence while maintaining the minimalist aesthetic. This remix replaces the fiddly manual winding mechanism with a stepper motor controlled by an ESP8266 microcontroller, bringing Internet-connected atomic clock accuracy to an elegant analog design. PLEASE COMMENT BELOW IF SOMETHING NEEDS CLARIFICATION **** Key Features WiFi NTP Time Sync - Automatically synchronizes with atomic time servers Automatic Power-Loss Recovery - Saves position to EEPROM during power failures and auto-advances to correct time on restoration Auto-Calibration - Press a button to easily set 12:00, then let it sync to the correct time Manual Adjustment Potentiometer - Fine-tune time offsets for daylight saving or preferences Automatic DST Handling - Smoothly transitions between standard and daylight saving time Non-blocking Operation - All functions run concurrently without affecting timekeeping accuracy
