This book has a lot of interesting ideas and information, but it also raises a lot of questions.
First of all, the cover says that the enclosed "CD contains all the software, photos and schematics needed...", but that's not true - there are no photos or schematics on it.
A lot of the schematics have errors, some of them very major - the kind that would blow a fuse. The text likewise has errors. It sometimes refers to custom parts, but often doesn't specify where or how to get them. Sometimes it omits pin numbers on ICs. In general, it is useful to someone who knows the field, but can be lethal to a true beginner.
But my main problem is this -- where did the material come from? Some of the programs have other people's names in them. The text and some photos refer to printed circuit boards, but there are no pc board layouts in the book. At one point, the text says to mount the supplied components, suggesting that someone, somewhere markets that project as a kit of parts.
In any case, I feel that there is just too much material in this book to be the work of a single author who also happens to have a full-time job. I think it would have been nice to specifically credit the source for each individual project, so that the reader would have a place to go for further information.
