Story
This product is a table clock being developed for display at Japanese electronic craft exhibitions.
I wanted many visitors to forget the time and enjoy it at this exhibition, and as a result, I came up with the concept of "a clock that melts time just by looking at it."
This clock consists of 14 servomotors and the same number of disks as the servomotors.
Red and green segments are drawn on the disk. Then, these disks are rotated accurately by controlling the angle of the servo motor.
With this control, a digital display such as a 7-segment LED is displayed only by rotation.
