The LEGO® MINDSTORMS® NXT 2.0 set offers hundreds of building elements, programming software, and powerful electronics that you can use to create amazing robots. But where do you begin?

This eagerly awaited second edition of the bestselling Unofficial LEGO MINDSTORMS NXT Inventor's Guide is your key to designing, building, and programming robots with the NXT 2.0 set.

You'll learn practical building techniques, like how to build sturdy structures and use gears, and gain a solid understanding of the set's NXT-G programming language. A series of projects new to this edition offers step-by-step instructions for building and programming six robots, each of which can be built with just one NXT 2.0 set, including:

• Inventor-Bot, a fast, simple, modular vehicle with treads
• Sentry-Bot, a robot guard that shoots balls at intruders
• Table-Bot, a vehicle that uses its antennae to avoid falling off a tabletop
• The Jeep, a four-wheeled vehicle that avoids obstacles and follows lines
• The Lizard, a large walking robot that uses the color sensor to detect and respond to different colored balls
• The Printer, a stationary robot that uses a pen or marker to draw letters, words, and shapes on paper

Additional resources include the Piece Library, which contains basic information on the more than 80 types of LEGO pieces in the NXT 2.0 set, and the Quick Reference, which lists the 34 types of standard programming blocks. So go ahead. Grab your NXT 2.0 set, fire up your imagination, and see what you can invent with The Unofficial LEGO MINDSTORMS NXT 2.0 Inventor's Guide.

The LEGO® Technic Idea Book: Fantastic Contraptions is a collection of hundreds of working examples of simple yet fascinating Technic models that you can build based on their pictures alone. Each project uses color-coded pieces and is photographed from multiple angles, making it easy to see how the models are assembled without the need for step-by-step instructions. Every model illustrates a different principle, concept, or mechanism that will inspire your own original creations. You're encouraged to use these elements as building blocks to create your own masterpieces.

The Technic models in Fantastic Contraptions include working catapults, crawling spiders, and bipedal walkers, as well as gadgets powered by fans, propellers, springs, magnets, and vibration. You'll even learn how to add lights, pneumatics, and solar panels to your own models.

This visual guide, the third in the three-volume LEGO Technic Idea Book series, is the brainchild of master builder Yoshihito Isogawa of Tokyo, Japan. Each title is filled with photos of Isogawa's unique models, all of which are designed to fire the imaginations of LEGO builders young and old.

Imagine. Create. Invent. Now, what will you build?

NOTE: The LEGO Technic Idea Book series uses parts from various Technic sets. If you don't have some of the pieces shown in a particular model, experiment by substituting your own parts or visit the No Starch Press website for a list of the special parts used in the book.

Needle felting is a new craft and is gaining in popularity. There are only a few books written on the subject and most of those focus on 'flat' needle felting on a surface. This book is about sculptural needle felting—creating 3-D animals and figures using the felting needle to sculpt wool.

The book shows the techniques and describes how the felting needle works with wool fiber to create felt, while explaining the differences between this art form and other forms of felting. The reader will learn how to hold the needle, what sort of materials to use, and why.

There are about 20 complete projects including various birds, bugs, four-legged animals, and people-each one unique and irresistible! Laurie also shows the reader ways to display their felted creations as mobiles, ornaments, or arranged in shadow boxes.
