“The Secret Life of Circuits” is here

《电路的秘密生活》（The Secret Life of Circuits）现已发布

Some pics, endorsements, and the reason the book exists in the first place. 这里有一些图片、推荐语，以及这本书诞生的初衷。

I try to keep marketing in check: I’ve been working on my latest book for more than a year but only posted about it once. 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: 我尽量克制营销：我为这本新书已经工作了一年多，但只发布过一次相关内容。当时，这本书还在排版和编辑阶段，所以我没指望有多少订阅者会下单。但现在，我很高兴地告诉大家，这本书已经正式出版并实实在在地摆在面前了——而且看起来非常棒：

Hardcover artwork. Full-color illustrations. Direct orders are shipping from the publisher as we speak; you can order here: No Starch order page 精装封面设计。全彩插图。目前出版社正在处理直接订单并安排发货；你可以点击此处订购：No Starch 订购页面

The 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. 《电路的秘密生活》也可在 Barnes & Noble 和亚马逊（包括德国、法国、波兰、西班牙、荷兰、瑞典、意大利、英国和加拿大的站点）购买。不过，由于物流复杂，这些订单将于 10 月发货。

The 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. 这本书是我在刚开始学习这门手艺时梦寐以求的参考书。它提供了真正的答案，却不需要你预先学习一年的微积分。它解释了如何构思自己的设计，而不是如何抄袭他人的作品。它专注于现代问题的解决，而不是电路考古。

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. 如果你是本博客的常客，你应该了解我的风格。《电路的秘密生活》采用了类似的方法，并得益于精心的设计和专业编辑的润色。它也很漂亮：这是一本大开本的全彩精装书，包含近 300 幅专为本书绘制的图表和插图。

If you’re still on the fence, here are some endorsements from fellow enthusiasts: 如果你还在犹豫，这里有一些来自同好们的推荐语：

“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” “阅读这本瑰宝般的书，就像是在 RadioShack 的零件抽屉里探险，还有一位专家在旁解释每个零件的用途以及如何用它们设计电子产品。没有比这更好的入门书了。” —— Travis Goodspeed，《Microcontroller Exploits》作者

“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” “《电路的秘密生活》既不是教科书，也不是肤浅的入门读物；它平衡了实用知识、数学和概念解释，且没有使用陈词滥调的类比。” —— Eric Schlaepfer，《Open Circuits》合著者

“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 “这是一次从底层物理到现代微控制器的电子学全方位之旅，书中提供了实践实验和见解，使阻抗匹配和天线等复杂主题也变得直观易懂。” —— Colin O’flynn，《The Hardware Hacking Handbook》合著者，电气与计算机工程助理教授

“Michal’s book bridges the difficult 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” “Michal 的书通过精美的插图和对电子物理学易于理解的架构，架起了理论与实践之间那道难以逾越的鸿沟。” —— Chris Gammell，《The Amp Hour》联合主持人

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. 我还收到了来自 Hacker News 的第一条“推荐”：“我看了样章，字体和排版在视觉上令人反感。” 所以，选它准没错。
