Part of the fourth installation in the best-selling LEGO® Technic Idea Book series by master builder and LEGO luminary Yoshihito Isogawa, this book helps you build compelling, non-electric contraptions. Get inspired by the fun, creative projects found in LEGO Technic Non-Electric Models: Compelling Contraptions. Each project uses color-coded pieces and is illustrated with photographs taken from multiple angles, making it easy to see how the models are assembled. The Technic models in Non-Electric Models don't require motors or sensors, making it easy for the novice Technic builder to get started. You'll build models that use cranks, cams, rubber bands, and flywheels, and create contraptions that lift, grab, and shoot things. Every model illustrates a principle, concept, or mechanism designed to inspire your own original creations. You'll learn the basics of mechanical engineering and understand the joy of making things that work. Compelling Contraptions features a variety of interesting mechanisms, including drawing devices, spinning tops, measuring tools, and stands for your phone or tablet. This visual guide is the brainchild of master builder Yoshihito Isogawa and is designed to fire the imaginations of LEGO builders young and old. Imagine. Create. Invent. Now, what will you build?
