This is a project from Sierra College Robotics Club, A glow-in-the-dark display, activated by UV LEDs scanning over a glow-in-the-dark surface. It displays messages, the time, and features various patterns and simple games!
See The Schematic and The Code to get started working with it.
The GlowClock design evolved from our previous project, the Whiteboard Clock, but with the goals of being more mechanically reliable, while showing a new and unique way of using technology we're all familar with: Glow in the dark materials!
The GlowClock is a collaborative effort by the Robotics Club, featuring PCB design and software by Patrick Leiser, with mechanical design and assembly contributions from many talented club members.
We presented the GlowClock at OpenSauce 2025, and were featured in This Video by Jeff Geerling. We also posted some media on our instagram
