Send a Raspberry Pi Back in Time to 1980

One of our favorite hacker-scavengers on YouTube, [The Post-Apocalyptic Inventor], has been connecting his Raspberry Pi up to nearly every display that he’s got in his well-stocked junk pile. (Video embedded below.)

Modern monitors with an HDMI input connect right up to the Pi. Before HDMI came VGA, but the Pi doesn’t do that natively. One solution is to use a composite-to-VGA converter and pull the composite signal out of the audio jack. Lacking the right 4-pole audio cable, [TPAI] soldered some RCA plugs directly onto the Pi, and plugged that into the converter. On a yet-older monitor, he faced a SCART adapter. If you’re European, you’ll know these — it’s just composite video with a different connector. Good thing he had a composite video signal already on hand.

With a (presumably) infinite supply of junk VCRs on hand, he pulled an upconverter out of the pile, and got the Pi working with the snazzy retro TV.

Chromecast Vintage TV Is Magic

When [Dr. Moddnstine] saw a 1978 General Electric TV in the trash, he just had to save it. As it turned out, it still worked! An idea hatched — what if he could turn it into a vintage Chromecast TV?

He opened up the TV and started poking around inside. We should note that old TV’s are pretty dangerous to open up if you’re not familiar with the components inside — high-voltages that could kill you linger on some capacitors. [Dr. Moddnstine] didn’t go into too much detail, so do a little extra research before you open up a TV.

Part of his goal for this project was to keep everything self-contained within the TV so all you would have to do is plug it into the wall in order to use it. Since the TV is so old, it doesn’t even have an analog RCA connections for a video input — just a VHF input. Because of this he needed to use three separate connection adapters to get the video signal to the TV.
