I guess I was expecting a bit more in the way of a technical kick in the seat of the pants than this turned out to be. Don't get me wrong, this has lots of examples of people tinkering their projects, but a little bit of this goes a long way for me. I've been tinkering since I was 7 or 8 (yup, 50 years now), so I was hoping to get back to more of that and expecting this book to help shine some light on a path. I guess in a way it does, but like I said, I expected more. Still, 4 stars ain't a bad rating. It's just not a 5 star book.
