'Antique' Auto Correcting Analog Clock
youmagine
"Retro Revival Auto Correcting Timepiece" is a meticulously crafted analog clock that pays homage to my grandmother's treasured timekeeper from years past. Her classic clock boasted a sturdy wooden case adorned with brass hardware and intricately engineered inner workings, which I've lovingly replicated using 3D printed wood and copper PLA for the casing, details, and inner mechanisms, paired with sleek black PLA clock hands. This modern masterpiece leverages an Adafruit Feather ESP 32 microcontroller, precision stepper motor, and controller to smoothly rotate the clock hands at a consistent rate of once per minute. The software is carefully designed to automatically align the clock hands to the 12:00 position upon startup or reset using a reed switch and magnets to detect the home position. The timekeeping system utilizes one of the numerous NTP clock servers to maintain accurate time, polling it at the top of every hour to synchronize with the ESP32's real-time clock. If the clock falls behind (determined by NTP time of 12:00, but the reed switch is not activated), the software seamlessly fast-forwards the clock to the correct position and resumes normal operation. As always, I'm confident that I may have overlooked a crucial file or two, so please don't hesitate to inquire if you have any questions – I'm prone to making mistakes after all. This project was carefully designed using Autodesk Fusion 360 and sliced with Cura 3.5.1 before being printed in PLA on my trusty Ultimaker 2+ Extended and Ultimaker 3 Extended machines.
