A collection of 16 fascinating scientific and technical projects to build with parts from the LEGO MINDSTORMS EV3 robotics set and other components. A great addition to any STEM curriculum or home library.

High Tech LEGO® hijacks the MINDSTORMS® EV3 revolution, showing you how to build creative technical inventions with practical applications. You'll learn to build a dynamic array of working devices for outdoor research, home security, spycraft, and more.

Among the book's 16 fascinating projects you'll find a motion-activated animal cam, a Morse code transmitter, a laser security fence, a motion-sensing radar detector, an automated insect trapper, and a heat-seeking infrared cannon. Welcome to a whole new world of building!

Every project brings together science, mechanics, electronics, optics, and software to create complex instruments for studying and measuring the world around you, all while maintaining the playfulness of LEGO. Each easy-to-follow model combines illustrated instructions with step-by-step guidance on the engineering methods at play.

As you build, you'll learn:
    "Illegal" modding techniques (that may include drilling, cutting and soldering -- Shh!)
    Different ways to work with diode laser modules
    Tricks for modifying EV3 sensors and motors
    The joy of hacking LEGO light bricks to make a flickering fireplace
    How to use MINDSTORMS to build your own contraptions!

Experiment on your own, and expand on your finished creations. Make a few adjustments so the Critter Cam triggers an alarm to scare away pests, or modify the Doppler radar to detect flammable gases. The possibilities are endless!

REQUIREMENTS: LEGO® MINDSTORMS® EV3 Home Edition Windows Vista or higher macOS 10.14 or earlier
