Aside from nostalgia, people claim to like CRTs because they’re apprehendable– the technology just makes more sense than the arcane wibbly-wobbly solid-state madness going on inside the driver chip of your new OLED. CRTs weren’t the first technology used to display moving images though, and their mechanical forebears were even easier to understand. For that reason we suppose it was only a matter of time before one of The Youths– in this case a British YouTuber by the name of [smill]–tried gaming on a mechanical television display.The game in question was Minecraft— because of course it was, that’s the new generation’s DOOM–and the mechanical TV in question is not a priceless 1920s antique but a commercial kit that reproduces [John Logie Baird]s 1925 televisor. If you’re not familiar, it uses a flat disk– called a Nipkow disk after its inventor– with a series of holes in a spiral to demodulate a single lamp’s brightness variations into monochrome image made of scan-lines. As you might imagine, the resolution depends both on the size of the disk and its speed, so with a tabletop example you’re not going to get much– in this case, 32 holes for 32 lines. At least they’re not interlaced this time.Getting a video signal from the computer to the LED in the televisor kit was the hard part of the hack. Aside from actually playing on the diminutive monochrome display, that is. There is a “video2NBTV” tool that can do the job, as the Narrow Band TV signal used by amateur radio enthusiasts still has the compatible timing values and modulation as what the televisor kit uses. We suspect that’s because the Televisor people used the modern NBTV standard as a starting point for their electronics, since [Baird]’s device reportedly ran 30 lines at only 5 frames per second, compared to the 32 lines at 15 FPS here.Some of you may turn your nose up at this as a mere YouTube stunt, which is fair enough. At the same time, we cannot wait for the eventual arms race. Imagine when someone decides to go for 4K cred? Staring through a supersonic Nipkow disk makes pointing a particle accelerator at your face downright mundane. The kit [smill] used was monochrome, but if you want to repeat his antics in glorious colour, you can 3D print your own TV.
