I bought this book with the expectation that it would introduce me to the ESP8266 (as one comes with the book). However, there is not enough information in the book regarding first time usage of the ESP8266 . I had to resort to searching the internet for clues. My issue was resolved by installing a driver (and not the driver that most YouTube videos identified).
The book is mostly projects and 3D printing of enclosures.
If you have experience with the ESP8266 already and are looking for some new projects as well as some nice 3D boxes to make then this book may be for you.
It is a little bit more for experts than beginners I think.
