LEGO TECHNIC is designed to allow builders to create more advanced models with moving parts, like those built with LEGO MINDSTORMS. The Unofficial LEGO TEC-HNIC Idea Book: Gears offers hundreds of ideas and examples for building mechanisms with TECHNIC. This volume focuses on gears and power transmission. The book is color throughout, with little to no text accompanying its diagrams; rather than tell the reader what to think, readers are encouraged to use their own imaginations. The book's illustrations demonstrate various ways to combine TECHNIC gears, which readers use as starting points for their own creations. Gears begins with the basics of gears, shafts, connectors, and gear combinations, then demonstrates more complex actions, like how to build winches, cranes, and chains; change rotational motion to linear motion; launch projectiles with rubber bands; change speed and direction; and even create musical instruments. These books are for anyone who wants to create a moving masterpiece, as well as those who want to make original robots with MINDSTORMS. It can also be used to demonstrate how machines work and to experience the fun of mechanics.
