It seems like this person is incredibly intelligent and resourceful. Why not just design a new PCB for this instead of modding one? Surely the component cost of 2 connectors and a little PCB could still be in the < $20 range and actually output good quality analog signals? $20 is the same as $3 if you’re also buying CRTs just to play Switch games. This is such a hobby level activity I’m sure people would love a kit + a guidebook, could even provide a 3d printed case.

Sometimes it's fun to mod something that other people can also easily buy and follow your mod recipe. It's more of a network effect than publishing Gerbers and a BOM.

For example, there are (or maybe were) lots of cheap LED controllers that use proprietary phone apps, but if you crack them open, you find that they're ESP-8266-based, and if you can find the right locations on the PCB, you can reflash them with WLED.

I think you misunderstand the obsessive, blissful, motivations of a nerd. :)

I was like this when I was younger, where a goal like this would entirely consume me, regardless of practicality, and more of a "see if I can". Some of the best days of my life, where I was most alive, were those times of complete, detrimental, obsession. As I grew older, and patterned by employment, it slowly faded, and sometimes I miss it so much.

(funny enough, I was once nerds sniped about a grids of resistors, to understand PCB trace resistance better, for high currents, because an EE said my intuition was wrong. I made a paint program where you could paint/paste an image, with red being + voltage sources, blue being negative, and greyscale being resistance, and it would show you the current flow through whatever you drew. I was able to prove that my intuition was actually correct!).

To reduce e-waste? Not everything has to be optimised on time or money spend.

Maybe the chips aren't available, or maybe they just wanted to tinker.
