LEGO Technic Non-Electric Models: Clever Contraptions

"If you ever wanted to understand how basic machines work or how to properly utilize gears to create motion, then the LEGO Technic Non-Electric Models: Simple Machines book is a great place to start your exploration. Yoshihito Isogawa truly is a master of his craft, and there is no better teacher to learn it from."

Praise for The LEGO Technic Idea Book series

"I can emphatically state that no self-respecting LEGO fan should exclude this series from their library."
Bricks in my Pocket

"These are an invaluable set of books to have as a reference to build mechanisms."
BrickJournal

"These are excellent books showing a lot of great ideas for LEGO mechanisms. Even if you're an experienced builder, there are surely some ideas in here you've never seen."
Brickpile

"I cannot recommend LEGO Technic Non-Electric Models: Simple Machines and LEGO Technic Non-Electric Models: Clever Contraptions highly enough for somebody looking to include mechanisms in their own models . . . There is plenty of clearly presented information to help a reluctant beginner to start experimenting and for the seasoned builder to expand their repertoire."
The Rambling Brick

"For those new to Technic building, the Simple Machines book is indispensable." The NXT STEP Blog
"These books look fantastic."

"For anyone who loves Lego, prototypes in Lego, or loves mechanical assemblies, these books are definitely required viewing, and we're not sure how we lived without them for so long."

"My whole family thoroughly enjoyed the books. If you're a Lego fanatic, you'll love them too."
The Father Life

"What I like about these cool little models is that they can be used to teach various science concepts such as gearing, Newton's Laws, and Potential & Kinetic energy to name a few."
The Robotic Realm

"Because the models range from practical tools for lifting, gripping, shooting, and measuring, to working gadgets, the immediate use of each tool was what enhanced our interest the most. The fact that they also demonstrate principles of mechanical engineering added to the fun."
