Scanwheel, a miniature mechanical TV [video]

The video showcases the Scanwheel, a tiny mechanical television mechanism. It demonstrates how rotating drums create moving images without electronics. The device uses a series of scanned lines to reconstruct visual frames. Close‑up footage reveals the intricate gears and light source in action. The Scanwheel exemplifies early concepts of image transmission. Viewers can observe the synchronization of rotation and illumination. The demonstration highlights the mechanical ingenuity behind the design. The clip serves as a historical reference for analog television technology.
