Are you fascinated by the power of even the smallest electronic device? guides you through step-by-step experiments that reveal how electronic circuits function so you can advance your skills and design custom circuits. You'll work with a range of circuits and signals related to optical emitters and receivers, audio, oscillators, and video. This practical resource explains components, construction techniques, basic test equipment, circuit analysis, and troubleshooting. Photographs, schematics, equations, and graphs are included throughout. By the end of the book, you'll be able to hack and modify existing circuits to create your own unique designs. Do-it-yourself experiments cover: "Excellent.... Nothing can replace hands-on experience and Quan immerses the hobbyist/designer right into the fray up to their elbows." is just what the title reflects. This is a terrific self-training/teaching manual, or perhaps even a textbook for a high school or early college electronics course. It's also a fun read for those times when you find yourself at loose ends on a contest-free weekend or feel the urge to tinker."
