💡Scanwheel: DIY Drum-Style TV With Five LED Windows
Build Your Own Retro-Futuristic TV with LEDs and a Raspberry Pi
TL;DR
The Scanwheel is an open-source DIY drum-style television using five LED windows. Requires a Raspberry Pi Pico, stepper motor, and specific resistors for image quality.
The Scanwheel is a unique DIY project that turns your home into a retro-futuristic TV studio with just LEDs and a Raspberry Pi Pico. This device features five side-by-side windows, each displaying separate images through RGB and white LEDs. If you're tinkering with hardware or want to explore the basics of LED control and stepper motor usage, this is for you. The Scanwheel uses a Symbol Technologies 21-02485 stepper motor, which needs special wiring adjustments, and requires a Pico W for wireless video streaming. With detailed instructions and 3D models available, it's an engaging project that showcases the power of DIY electronics.
Key Points
The Scanwheel features five separate windows, each measuring 9mm x 8mm with 20 scan lines per window.
A Symbol Technologies 21-02485 stepper motor is required for the build, needing a cut wire to function as a bipolar stepper motor.
Each LED requires current-limiting resistors to prevent excessive power draw from the Pico's GPIO pins; total power draw must not exceed 50mA.
The Scanwheel design uses Raspberry Pi Pico and Pico W for control and wireless video streaming, respectively.
3D models are available in the parts directory, consisting of a base, drum, lid, and an OpenSCAD model for custom modifications.
Why It Matters
If you're into DIY electronics or want to explore LED control and stepper motor usage, the Scanwheel offers a unique project. It uses a Raspberry Pi Pico and specific resistors for high horizontal resolution, making it perfect for hobbyists looking to build something truly unique.
