Tell time with a servo-driven skull clock!
While model skulls are generally relegated to Halloween, or biology class, this maker decided to construct a very unique clock out of one.
The “hands” of the terrifying timepiece are represented by two eyes—right for hours, left for minutes—that are rotated about using a pair of 360-degree (but not continuous rotation) servos. If this wasn’t freaky enough, a third servo pulls the jawbone open with a thin cable, which then snaps shut with springs to “chime” the hour.
An Arduino is used for control of the assembly, along with a DS3232 RTC module to keep things accurate. A nice octagonal frame was built for it as well, giving this otherwise strange creation a classy home in which to reside.
