The Edgytokei is a nunchucks-inspired edge clock

Just when you thought you’d seen every possible hacked clock design, creator Ekaggrat Singh Kalsi has come up with something new: a faceless clock that is able to tell time with two hands that never make a full rotation.

Instead, an Arduino Nano powers a novel mechanical gear assembly via two motors, which causes the two hands to physically switch positions between the second arm being mounted on the base and on the tip of the first arm. This strange representation of time changes form every fifteen minutes.

The Edgytokei which literally means edge clock is inspired from the Japanese nunchucks. Just like the nunchucks the clock is just a pair of two arms displaying time by balancing themselves on the edge. The clock consists of two arms and the base on which the arms are anchored. Both the arms are of equal length as the role of the arms changes with different hours of the day.

The fulcrum of the clock flips from the center to the left or right of the clock every quarter hour so that the clock can stand on the edge to represent the time between quarter past and quarter to hour. This flipping of the arms keeps the clock dancing on the edge throughout the day. The base which contains the electronics of the clock provides a anchor for the clock and prevents the arms from falling over.

If that sounds unique, then wait until you see it in action below. More details on the build can be found via this Hackaday write-up.
