At the time, the book was still going through layout and editing, so I didn’t expect many subscribers to pull the trigger. But now, I’m happy to report that the book is actually, physically here — and is lookin’ good:Hardcover artwork.Full-color illustrations.Direct orders are shipping from the publisher as we speak; you can order here:No Starch order pageThe Secret Life of Circuits is also available from Barnes & Noble and Amazon (including regional sites in Germany, France, Poland, Spain, Netherlands, Sweden, Italy, United Kingdom, and Canada). That said, logistics are hard, so these orders will ship in October.Order from Amazon for October deliveryThe book is the reference I wish I had when first learning the craft. It gives real answers but doesn’t demand a year of calculus beforehand. It explains how to come up with your own designs, not how to copy other people’s work. And it focuses on modern problem-solving, not on circuit archaeology.If you’re a regular to this blog, you know my style. The Secret Life of Circuits takes a similar approach, with the added benefit of careful design and a skilled editor. It’s also pretty: it’s a premium-size, full-color hardcover with nearly 300 diagrams and illustrations crafted specifically for that occasion.You can check out the sample chapter here, or get a sense of the approach from the following blog posts:But good sir, what is electricity?lcamtuf·February 23, 2025Read full storyThings you can do with diodeslcamtuf·November 2, 2025Read full storyNegative resistancelcamtuf·Jul 23Read full storyDACs and ADCs, or there and back againlcamtuf·February 19, 2024Read full storyIf you’re still on the fence, here are some endorsements from fellow enthusiasts:“Reading this gem of a book is like exploring the component drawers at RadioShack, with an expert on hand to explain what each part does and how to design electronics with them. There is no better introduction.” — Travis Goodspeed, author of “Microcontroller Exploits”“The Secret Life of Circuits is neither a textbook nor a trivial introduction; it’s a balanced mix of practical knowledge, math, and conceptual explanations free of clichéd analogies.” — Eric Schlaepfer, co-author of “Open Circuits”“A complete tour of electronics from low-level physics to modern microcontrollers, along the way providing hands-on experiments and insights that make even complex topics like impedance matching and antennas feel intuitive.” — Colin O’flynn, co-author of “The Hardware Hacking Handbook”, assistant professor of electrical and computer engineering“Michal’s book bridges the dif cult chasm between theory and practice with beautiful illustrations and an easy-to-understand framing of the physics of electronics.” — Chris Gammell, co-host of “The Amp Hour”I also have the first endorsement from Hacker News: “I looked at the sample chapter, the fonts and layout are visually repulsive.” So, you can’t go wrong.As always, the book and the blog are:1692ShareDiscussion about this postCommentsRestackslcamtuf’s thing reply rulesJohn B3dLiked by lcamtufJust received the physical copy in the mail today.

The book The Secret Life of Circuits is presented as a comprehensive resource designed to serve as the essential reference for individuals learning the craft of electronics. The author intended the book to provide practical answers to complex electrical concepts without prerequisite knowledge of advanced calculus, focusing instead on enabling readers to develop their own designs rather than simply replicating existing works. The text emphasizes a focus on modern problem-solving methodologies over the more esoteric practice of circuit archaeology. The publication itself is characterized by careful design and skilled editing, offering a premium format as a full-color hardcover replete with nearly three hundred diagrams and illustrations.

The content spans the complete spectrum of electronics, offering a complete tour ranging from low-level physics to modern microcontrollers. It is framed to make inherently complex subjects, such as impedance matching and antenna theory, feel intuitive through the inclusion of hands-on experiments and insights. The book addresses fundamental concepts, including the nature of electricity, the function of diodes, the operation of digital-to-analog converters and analog-to-digital converters, and related topics.

The book has garnered significant acclaim from fellow enthusiasts and experts. Endorsements highlight its balanced approach, noting that it successfully bridges the gap between theoretical knowledge and practical application through beautiful illustrations and clear explanations of electronics physics. Reviewers suggest that the work functions not merely as a textbook or a trivial introduction but as a balanced mix of practical knowledge, mathematics, and conceptual explanations free from simplistic analogies. For instance, one reviewer described the book as an exploration of component drawers at a hardware store with an expert guiding the process, making it an unparalleled introduction.

The work is attributed to the author lcamtuf, and the quality of the presentation, including the visual layout, has been noted by various observers. The book is currently available through various retailers, including Amazon and Barnes & Noble, with international shipping options available. The general consensus among those who have engaged with the material is that it provides an optimal introduction to electronics by integrating foundational knowledge with advanced problem-solving techniques.
