I usually have some one-off projects I work on when I have nothing more important to work on. Usually to learn something new and/or do something weird. These are generally useless for other people.
I just finished one of those. It's a software-defined analog video decoder because why would you buy a capture device if you can instead have fun making one, right? It's an ADC running at 20 MS/s connected to a RPi Zero connected to a Mac. The Mac app does the decoding.
