I do this by creating a side project with a concrete objective. I then do my best executing the side project. After I get something useful doing the Side project then I try to give a presentation about the side project. Note that I have failed multiple times with getting something useful enough to justify the Side project. Another way you can do this is just promise to give a presentation about the topic at a local meetup. And keep on giving presentations about it.
