Ask HN: Looking for a Winter Project / Hobby

Hey, So with the dark nights quickly upon us and a few days off over the festive period I am looking for a little project as I don't really like sailing or cycling in the freezing cold. So I was curious what everyone on here does for fun outside of coding? I'm tempted to have a go with RC planes and see if I can do something interesting with coding and an RC plane. However, open to some interesting ideas. I sail a lot so a little sailing project would be fun as well.
