We’ve covered a few Raspberry Pi Pico clocks over the years but we haven’t quite seen one like this beautiful marble clock. Created by maker and developer C Forde, this clock uses marbles to display the time. There are two marbles used in this clock that shift up and down spiral towers—one to display the hour and one to indicate the minute.
The design consists of two custom-built towers housed inside of a wooden case with acrylic windows. In addition to the marble display, a digital clock is also mounted to the front panel which is also operated by the Raspberry Pi Pico. It can be disabled, however, allowing the marble design to be the star of the show.
