I've been contributing to open source projects for a decade or so, mostly in bursts - when I was still 100% hands-on, I'd work on projects that either interest me, or are used at work (e.g. Rails). Over the past few years I've mostly been working in leadership (but still with a bit of hands-on), so I mostly work on things that interest me. For example, for a while I was obsessed with building a web scraper, and some machine learning stuff, so I built: https://github.com/fredwu/crawler https://github.com/fredwu/crawler and https://github.com/fredwu/simple_bayes https://github.com/fredwu/simple_bayes Working in bursts works well for me, as I can dial the effort up and down depending on my availability and mental space.
