If you’re a collector of older TVs, you’re probably facing the problem in some form of having no transmissions to tune in to. With many sets you can use a …. An Analog TV Station For Anyone.
With many sets you can use a SCART or other A/V input, but nothing beats using the thing as it was intended. [BorisDigital] had exactly this problem, and since he worked in a TV transmitter control room in the 1990s, he’s made a small TV station that looks and operates like the real thing. It’s a 10 inch rack stuffed with goodies, each of which replicates the function of a piece of broadcast gear which would have cost a small fortune back in the day.
At the top is a transmitter, a relatively inexpensive board from China. Below it a clock and audio monitor powered by a Pi Pico, then a vectorscope, waveform monitor, and monitor powered by a set of Pi 5s with USB video digitisers, a pair of SD card video record/play units — yet more Raspberry Pi — and at the bottom, an automatic scheduler powered by another fruity board from Cambridge. If you’re not into TV the construction may be worth a second look.
Those neat looking rack front panels are 3D printed with different filaments for the lettering, and are both solid and stylish.
