Raspberry Pi Laser Pointer Turret
Arduino Powered Plot Clock
UV Glow-In-The-Dark Laser Displays
This projects relies on two main components.
UV light and phosphorescence glow material.
You can try this at home using a glow in the dark sticker and a small led and coin cell battery and "paint" with light!
I use either an Arduino or Raspberry Pi, motors (servos or steppers) and UV leds to create these "displays".
Build your own with the tutorials in the instruction sections!

I like the silicone belt! I bet you could make it work by just making the rollers even slightly convex, and removing the flanges. Then the belt will self-center. Same would work for the tape, probably with less effort, then you could tighten it up a little.
