Scanwheel: A Pocket-Sized POV TV
A handheld device called the Scanwheel uses a spinning disk and LEDs to create a miniature television display based on the persistence of vision effect. The device is built using a Raspberry Pi Pico, a stepper motor, and 3D-printed components, allowing it to produce a color 20×20 pixel display and two additional black-and-white displays. This innovative project demonstrates how simple electronics can be used to create a functional and visually engaging display in a compact form.
