With more than 150 color images, step-by-step instructions and detailed explanations, and a handy materials list of components and sources, this is the ultimate guide to explore the hidden universe of radio waves!

Radio waves are all around us. They're used by cell phones, Wi-Fi routers, TV dishes, and even satellite networks to convey data on thousands of different frequencies. When we unlock a car door with the push of a button or stream music to wireless earbuds, that's radio. It's a simple yet dynamic technology that has been harnessed by creative experimenters for over a century--and now you can join the adventure!

Author Fredrik Jansson demystifies the world of radio through a dozen innovative projects, enabling readers to build inexpensive radio circuits such as transmitters and receivers, remote controls, and a working metal detector. Radio concepts are also adapted for the Raspberry Pi Pico, updating classic concepts with contemporary tools for accuracy and power.
