I love this mindset. I think as engineers we often get discouraged when we feel like our own implementation of something could never be as good as what's already out there (at least, I do). But the question that should be asked is: "Would it make me happy to do it myself?" If so, then who cares! Hobby projects are about making yourself happy. There's nothing wrong with doing something purely for fun.
