TL;DR
The Scanwheel is a pocket-sized television that uses the persistence of vision effect to display images. Created by a maker known as Ancient, this innovative project combines a spinning disk and LEDs to generate visuals in a compact form. Instead of the traditional bulky screens we're used to, the Scanwheel leverages a Raspberry Pi Pico microcontroller to manage motor speed and LED timing, along with a small stepper motor and motor driver.
