A Hands-On Lab Course
This introduction to circuit design is unusual in several respects. First, it offers not just explanations, but a full course. Each of the twenty-five sessions begins with a discussion of a particular sort of circuit followed by the chance to try it out and see how it actually behaves. Accordingly, students understand the circuit's operation in a way that is deeper and much more satisfying than the manipulation of formulas. Second, it describes circuits that more traditional engineering introductions would postpone: on the third day, we build a radio receiver; on the fifth day, we build an operational amplifier from an array of transistors. The digital half of the course centers on applying microcontrollers, but gives exposure to Verilog, a powerful Hardware Description Language. Third, it proceeds at a rapid pace but requires no prior knowledge of electronics. Students gain intuitive understanding through immersion in good circuit design.
The course is intensive, teaching electronics in day-at-a-time practical doses so that students can learn in a hands-on way.
The integration of discussion of design with a chance to try the circuits means students learn quickly.
The course has been tried and tested, and proven successful through twenty-five years of teaching.
The book is practical: it avoids mathematics and mathematical arguments and even includes a complete list of parts needed in the laboratory exercises, including where and how to buy them.
The much-anticipated new edition of 'Learning the Art of Electronics' is here! It defines a hands-on course, inviting the reader to try out the many circuits that it describes. Several new labs (on amplifiers and automatic gain control) have been added to the analog part of the book, which also sees an expanded treatment of meters. Many labs now have online supplements. The digital sections have been rebuilt. An FPGA replaces the less-capable programmable logic devices, and a powerful ARM microcontroller replaces the 8051 previously used. The new microcontroller allows for more complex programming (in C) and more sophisticated applications, including a lunar lander, a voice recorder, and a lullaby jukebox. A new section explores using an Integrated Development Environment to compile, download, and debug programs. Substantial new lab exercises, and their associated teaching material, have been added, including a project reflecting this edition's greater emphasis on programmable logic.

From Rubbing Amber to Swiping Glass
"The story of electricity, told one connection at a time."Why does rubbing amber attract dust? How did we go from that curious effect to a world where screens respond to a single touch? And how did we get from mysterious sparks to tiny chips packed with billions of transistors?
For centuries, electricity puzzled and fascinated those who encountered its curious effects—long before it even had a name. From the earliest observations of static charge to the complex electronics that shape our lives today, this book traces the gradual, and often surprising, story of how humanity came to understand and harness this powerful force.
This book offers an engaging and accessible account of the people, ideas, and inventions that transformed electricity from a scientific curiosity into the foundation of our digital age. Along the way, you’ll meet a host of inquisitive minds—some famous, others less so—whose persistence and creativity helped unravel the mysteries of the natural world and gave rise to the technologies we now take for granted.
Covering everything from Leyden jars and batteries to transistors, microcontrollers and the internet, this book presents a clear and enjoyable overview of electronics and its relatively short, yet rich, history.
Whether you have a technical background or simply a curiosity about how things work, From Rubbing Amber to Swiping Glass offers a thoughtful look at how far we’ve come—and a gentle nudge to wonder what might come next.
