Beginning Analog Electronics through Projects: Second Edition

Book Preface

Much has transpired between the release of my first edition of Beginning Electronics Through Projects, published in 1997, and this second edition, Beginning Analog Electronics Through Projects. For the most part, I’ve been busy developing several new books, including Practical Audio Amplifier Circuit Projects and Beginning Digital Electronics Through Projects.You’ll find many significant differences between the first edition of this book and the current edition, many of which you’ll need to know to proceed with the projects. Please refer to the introduction for a list of the key changes.

There will no doubt always be a succession of new-generation enthusiasts embarking on their first introduction to electronics (be it for fun or work), and on the lookout for easy-to-understand introductory books on the subject. For those beginner enthusiasts and hobbyists, my books are suited to your needs.

Have fun building the projects and, at the same time, increasing your working knowledge of electronics.

I had fun working with you, Candy!
