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 (nostarch.com) for a list of the special parts used in the book.
