I don't know if anything like this exists near you, but I've heard of community centres/churches that organise something like a skills library/drop in, where people who have skills they can use to help others - people who can mend/fix/repair/adjust things (electronics, woodwork, clothing, cooking, software) and or also teach the basics to others so they can do more themselves, volunteer for a few hours a week and do just that for the community.

I found this example (E: their FAQ) of a London "Repair café" where they do this kind of thing to give you an idea, and if there is nothing like that that exists near you, it would be a great project to try and start with your local community!
