Build a Spinning Mechanical TV with a Raspberry Pi Pico
Maker James Brown rebuilt a 1920s mechanical TV using a Raspberry Pi Pico, a stepper motor, and five LEDs. The device uses a spinning disk with 20 pin holes to create a 20-pixel-tall image through persistence of vision. The project costs under $20 and offers a hands-on lesson in stepper control and display technology.

A clever DIY project that demonstrates persistence of vision and stepper motor control, but its practical use is limited to hobbyist education.
