An Amazing Giant Arduino Electro-Mechanical Clock

Sometimes you want your creation to look great. That was the case here, as this electromechanical clock integrates several different types of metal along with a chain drive into something that’s as much a work of art as it is a practical timekeeping tool.

This clock was designed, machined and assembled, every piece from scratch (apart from a couple of the small chain sprockets and chains themselves). The timekeeping and motor/position control software was also developed and programmed 100% from scratch as well. All the parts are made out of a combination of copper, brass, steel, aluminum, and stainless, and the assembly is driven by an Arduino Yún running a NEMA style stepper motor, and Honeywell automation Hall effect sensors for the mechanical position readings.

Upon startup, the device is able to auto-calibrate using a clever sensor setup on the hour hand wheel to make sure it’s at 12:00 noon/midnight, then uses the Arduino Yún‘s built-in WiFi support to check the time off of the Internet and configure itself accordingly.

More details in the video below and on its creator’s Reddit post.
