I bought this book to get a better idea of how to safely interface my own circuits to the Lego Mindstorms NXT. In my opinion, you can't find a better book for this purpose. "Extreme NXT" contains the pinouts and proper usage of the NXT motor and sensor ports. It also provides a large number of the most useful homebrew sensor implementations, right down to parts lists containing part numbers for common component suppliers like Digikey and Radio Shack.

My background is in engineering, with an emphasis in control systems. The first book I read in the field of hobbiest robotics was "Mobile Robots: Inspiration to Implementation" (Jones and Flynn). In those days, the 6811's were king for these sorts of projects. I spent many a happy day with my MIT Handyboard (a simple 6811 robot controller board). Things have come a long way. Nowadays NXT is available, and this book is the modern day equivalent to that excellent text for those who want to dig in and find out what the NXT is capable of. The book is written in a format that is easy to understand for the novice, but also supplies plenty of content to allow the more advanced user to be able to push the NXT envelope. The organization is superb, commonly used charts and tables are easily found. I have been finding myself referring most often to the pinout tables for the NXT connectors, and these are very conveniently found towards the front of the book.

Chapters are broke down into sensor and output types, starting with the more basic and easily contructed passive sensors up to more advanced and expandable I2C sensors. Motor control, h-bridges, etc are also covered in detail. Both the construction of the circuits, and the NXT code to run them, are covered. Code is provided in it's most basic form first, NXT-G, which every NXT user will be familiar with. Examples proceed to more complex compilers, such as NBC, for sensors or circuits that are better suited to those implementations.

The appendix provides complete source code listings, useful websites and links categorized by chapter. There is also a great tutorial on prototyping with breadboards and perfboard for the uninitiated. With this book, any skill level in electronics should be enough to do some cool things with the NXT kit.

This book will become a very useful addition to any hobby robotics library. For me, it will be the goto book for designing circuits to safely interface to the Lego NXT. Highly recommended!

Reviewer J. Doubek, said it best - "I bought this book to get a better idea of how to safely interface my own circuits to the Lego Mindstorms NXT. In my opinion, you can't find a better book for this purpose."

And that is very true! I cannot add much more to his review... This book is the 'Make' book for the NXT. The authors have explained everything so any builder of any age or skill level can understand the processes. It teaches several techniques that can be developed into viable career skills. Including soldering, electronics knowledge and usage, and handy-tech projects that will also get one's mind flowing with other ideas. If you are a 'Maker' or tinkerer or would like to learn some inside knowledge of the NXT and how to build outside of the box you will find no better starter book.

Grab it, read it, and use it to expand your NXT knowledge!

This book is excellent -- clear, detailed, and well-organized. And it always seems to have just the information I need.

To give a specific example: I was recently trying to prepare a robot for a local fire-fighting contest, and was counting on using a HiTechnic interface board to connect up one or more Sharp analog distance sensors. But the HiTechnic board didn't work for me, and the deadline was looming. I flipped through Extreme NXT, and there in Chapter 8 was the solution: a simple circuit for that does exactly what I need.

The NXT is a great robot controller, and this book effectively converts it from a closed to an open platform. I can't recommend it highly enough.

This book continues to be an excellent source of information, both from a (re-)learning and reference standpoint. There is just the "right amount" of information, allowing a complete understanding of the technical details involved with enhancing the capabilities of a LEGO robot!

Was checking out the second edition, and realized that my positive opinions were never expressed for the original book. Needless to say, it is highly recommended!

I found a pdf of this book on the Internet, but was so impressed with it that I immediately purchased a paper copy. I just know that this book will be getting a lot of use. I'll be adding notes, writing in the margins, trying out circuit variations, etc. My workshop is in my basement but I build Lego models upstairs. I know this book will spend equal times in both places.

This book is filled with solid information like circuit diagrams, construction suggestions, component layout, pretty much everything you need to use the NXT to build practical and fun devices.

I've got boxes of electronic components, and I can't wait to start attaching them to the NXT system -- temperature probes, light sensors, Pots, motors, relays, LEDs. I even have a old joystick controller for some sort of remote-control car that I picked up at a surplus electronics shop. This book offers real advice on how to how to do everything.

If you own a NXT system and know how to use a soldering iron, then get this book. You will love it.
