Back in the past, we didn’t have fancy digital clocks. No, we have a good analog clock with a big hand and a small hand. If you want to know the time, you must look at the clock and find out which number each hand points to, or to some extent. It’s not easy. We like it.
Now, an analog clock appears. It’s just a pointer – no dial, no number, just a pointer. How is this possible? This clue appears in the name of the clock: akurobatto, and in the video below, which shows the acrobatic action of both hands when the clock is working. The unlikely watchmaker [ekagrat Singh Kalsi] of the series apparently thought a lot about this mechanism, which consists of a pointer and a separate base. The hands are connected together at one end and driven by a small stepping motor. The base has two docking areas, and the servo driven claw can grasp the hand assembly at the central pivot or the tip of either hand. By moving back and forth at the transition point, both hands sweep through time and minutes with amazing readability.
Although akurobato’s design is cool, its internal structure is actually another matter. There are customized slip rings to power the motor and arduinos that control the motor, sensors to determine the position of each hand, and customized stepping motor gearbox. The locking mechanism on the base is also worth studying – this is not easy to do.
In short, an impressive physique. Whether time is displayed on a phosphorescent screen or on a sequin, it seems that [ekagrat] has a unique clock.
