'Antique' Auto Correcting Analog Clock

"Timeless" Timekeeping Masterpiece: A Digital Clock with Analog Charm I've created a stunning analog styled clock that pays homage to my grandmother's cherished timepiece from years ago. Her clock boasted a solid wooden case adorned with brass hardware and intricate inner workings, which inspired me to design this modern take on the classic. The 3D printed case is crafted from a combination of wood-like PLA and copper-infused PLA for added realism, while the clock hands are precision-cut from black PLA. What sets my creation apart is its innovative use of technology. Instead of a traditional spring-driven windup mechanism, I've employed an Adafruit Feather ESP32 board, stepper motor, and sophisticated controller to drive the clock hands with pinpoint accuracy - once per minute, every time. The system is designed to "home" itself on power-up or reset by detecting the 12:00 position using a reed switch and magnets. To ensure precise timekeeping, I've integrated one of the numerous NTP (Network Time Protocol) servers into the software. Every hour, the system polls the server for the current time, which is then recorded in the ESP32's real-time clock. If the clock falls behind schedule, the software seamlessly fast-forwards it to 12:00, ensuring accuracy at all times. As with any project of this magnitude, I'm confident that a few files may have slipped through the cracks - so don't hesitate to reach out if you notice anything amiss. The design was meticulously crafted using Autodesk Fusion 360 and sliced with Cura 3.5.1 before being printed on an Ultimaker 2+ Extended and an Ultimaker 3 Extended, both of which provided exceptional results.
