When [FinnAndersen] found an old TV set by the side of the road, he did what any self-respecting DIY/gaming enthusiast would do: He took it apart and installed a Raspberry Pi 3 running RetroPie in it in order to play retro games on a retro TV!
[Finn] took the CRT out of the TV before realizing that it actually worked. It was already too late, so [Finn] ordered a 12″ LCD screen to put in its place. He liked the idea of the curved screen the CRT had, though, so he molded a piece of acrylic around the CRT and, after some cutting and grinding, had it fitting in the screen’s space.
[Finn] also liked the idea of the TV still being able to view a television signal, so he bought a TV tuner card. After a couple of mods to it, he could control the card with the TV’s original channel changer. He used an Arduino to read the status of the rotary encoders the original TV used. After some trial and error, [Finn] was able to read the channel positions and the Arduino would send a signal to the channel up and down buttons on the tuner card in order to change the channel.
Next up was audio. [Finn] found a nicer speaker than came with the TV, so he swapped them and added an amplifier. The original volume knob is still used to control the volume. A USB Hub is hidden in the side of the TV at the bottom, to allow controllers to connect and finally, a power supply converts the mains voltage to 12V DC which runs both the Raspberry Pi and the TV Tuner.
[FinnAndersen] has built a great RetroPie cabinet reusing a great looking vintage TV. It’s unfortunate that he removed the CRT before figuring out that he could use it, but the replacement looks pretty darn good! And the added advantage? It’s portable, sort of. At least, without the CRT inside, it’s much lighter than it was. Here‘s another retro console inside an old TV, and this article is about connecting a Raspberry Pi to every display you can get your hands on.
