Build a Palm-Sized POV TV With a Raspberry Pi Pico
A maker known as Ancient created a Scanwheel, a mechanical TV that fits in your hand using persistence of vision. The device uses a Raspberry Pi Pico, a stepper motor, and five LEDs to display a 20x20 pixel color image flanked by two monochrome panels. The build guide, firmware, and disk files are available on GitHub for hobbyists to replicate.

A clever weekend project that demonstrates the Pico's capabilities, but its niche appeal limits broader impact.
