Free book, so there's no complaint there. I haven' t read the whole book...I haven't made anything. These are just some thoughts that came to me as I skimmed the first half. After each project, there are some related projects. My kindle keyboard will open the related project's page on the web but not the instructions. It's nice to have some choices presented, however. Some of the pictures are too dark to be clear...some projects have page after page of instructions. Readers will choose to make some, none, or all of the projects. For me the real value of this book is that it introduced me to the Instructables site and the community there. They seem to have an idea which needs to spread to more people. Don't rush to spend money on things. Take some time and make them yourself. Use them awhile. Perfect them. Then pass the idea along to your family, friends and neighbors.
