I seem to recall a short lived blogs.perl post along these lines. How do you know nobody uses your stuff? I don't think it's fair to brand all fresh graduates in this way, nor understand what point you're trying to make regarding Python. Going down the route of selling hardware kits yourself I don't believe will resolve whatever problems you're concerned about. Some of what you wrote here seems contradictory. If as you say you enjoy these things why wouldn't you do it? What more justification do you want?
Update: Part of this reply doesn't make sense now, as OP edited the post, removing part of what they said.
