Redditor/machinist Spdltd was commissioned to create a steampunk, Arduino-powered electromechanical clock that uses a combination of belts, dials and needles arrayed across the wall to tell the time.
Pieced together from copper, brass, steel, aluminium, and stainless steel, this outlandish design uses an Arduino Yun — a combination Linux and Arduino microcontroller board — to control the stepper motor and query the internet for the local time. Upon boot, the clock auto-calibrates by rotating the clock face until a sensor detects an extra peg and uses that to zero on twelve o'clock; the Yun then grabs the local time over the WiFi and sends the stepper motor a-spinning 'till the correct time is displayed.At first glance, you may find it hard to get an accurate read of what time it is, but an accent piece's pegs denote the quarter hour once it lines up with the notch above each hour. At least this one doesn't require you to match colours or do much math to check the time.
