This giant electromechanical clock is a work of art

With some projects, your goal is to get it working to prove out a concept for a larger project, or simply to satisfy your curiosity. On the other hand, sometimes you want your creation to look great. That was the case here, as this steampunk-inspired 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.

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 query the Internet for the time and configure itself accordingly.

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.

You can find more details in the video seen below, and on its creator’s Reddit post.
