Rodrigo Feliciano’s nifty Raspberry Pi TV simulator lets you relive the classic tube set days without having to actually buy one. Well, you will need an old tube TV shell for the authentic look, but rather than controlling things with a remote, you change channels using a dial on the side.
For those interested in making their own, you’ll need a Raspberry Pi 3B+, an Arduino Mini Pro or Raspberry Pi Pico, a relay board, level shifter and a regulator module. However, you’ll want to be well versed in electronics, as CRT televisions operate at high voltages, so its capacitors can be quite shocking, literally. Users can program the TV channels with a custom Python script. Download the plans here. Or, you can use LEGO and a Raspberry Pi to build a scanner.

The Raspberry Pi change a random movie file in the folder ‘movies’ when the TV is showing a static noise. The static noise is provide by the TV circuit. A Arduino Mini Pro get the voltage on the tunning potentiometer and turn a relay on or off, selecting the TV composite video input or the noise from the TV circuit,” said Rodrigo.
