I wanted to build an unusual clock, and i had some UV Led's and glow in the dark filament on hand so here we are.
The glow disk is printed using glow in the dark (uv) PLA plastic
Other parts used...
Arduino Nano (v3)
10x UV LED's (5mm)
1x 28BYJ-48 Motor (cheap stepper motor)
1x DS1307 RTC clock module
Also used was some Black PLA for the base and some M3 nuts and bolts to mount the motor.
