Make a Portable Wide-screen Mechanical TV
Summary
IEEE Spectrum covers a portable electromechanical TV project (Scanwheel) that revives early Nipkow-disk display concepts with modern components. It details hardware choices (RP2040, Raspberry Pi Pico, LEDs, 3D-printed drum) and open tooling (GitHub/OpenSCAD) to enable replication and exploration of retro display tech.
