I made this for my wife and I's retro gaming collection to plug the consoles into a modern TV via a gbs-control-based line doubler. Most existing solutions for doing this we found to either be too expensive, only supported one video format which meant I couldn't connect other consoles, or lacking remote control in some way, so I made this. It also drives standard 12V RGB LED strips so it looks nice on shelving!

It's based on the famous Ben Heck design of using SN74CBT3244 FET bus switches to switch the audio/video signals, but with a few extra convenience enhancements, like supporting both RGBS and YPbPr video formats.

I wrote up everything and published all source code and schematics to a GitHub repository which you can check out if you want the details (I'll link it to the project page, but if you can't find that, it's here).

I got a v0.1 PCB made at JLCPCB which was rife with design problems, so I don't have a physical v0.2 PCB to upload here yet. At least the set up at home will look nice when it's done...
