Michael Jay Geier has been an electronics technician, designer and inventor since age 6. He took apart everything he could get his hands on, and soon discovered that learning to put it back together was even more fun. By age 8, he operated a neighborhood electronics repair service that was profiled in The Miami News. He went on to work in numerous service centers in Miami, Boston and Seattle, frequently serving as the “tough dog” tech who solved the cases other techs couldn’t. At the same time, Michael was a pioneer in the field of augmentative communications systems, helping a noted Boston clinic develop computer speech systems for children with cerebral palsy. He also invented and sold an amateur radio device while writing and marketing software in the early years of personal computing.
Michael holds an FCC Extra-class amateur radio license. His involvement in ham radio led to his writing career, first with articles for ham radio magazines, and then with general technology features in Electronic Engineering Times, Desktop Engineering, IEEE Spectrum, and The Envisioneering Newsletter. His work on digital rights management has been cited in several patents. Michael earned a Boston Conservatory of Music degree in composition, was trained as a conductor, and is an accomplished classical, jazz and pop pianist, and a published songwriter. Along with building and repairing electronic circuitry, he enjoys table tennis, restoring antique mopeds, ice skating, bicycling, and banging out a jazz tune on his harpsichord.

This is, hands down, the best book I have ever read on understanding electronics. I've had college and post-graduate courses that taught me how to analyze circuits and figure out what voltages, currents, resistances, etc. were at certain points. That was all well and good, but totally useless for anything that I wanted to do on my work bench.
In reality, what I needed was a holistic approach that narrated the circuit and the signals that are manipulated. I NEVER thought of circuits this way and the author was able to explain that the active elements are the players in the story and everything else is a supporting cast.
I could read a schematic, but I couldn't understand why the components were there. I know that a capacitor doesn't pass DC, but now I see that when placed in the circuit, it acts as a DC filter to remove noise before passing a signal to the next stage.
On top of all that, I realized that every circuit has a voltage that is used as a signal. Signal analysis, analog and digital, seemed like a very advanced topic that I only understood through major concepts (linearity, aliasing, etc). Now I realize that a battery and a light bulb has a signal just as a digital video camera does. One is just more complex.
Bottom line, this is the book that I couldn't put down...and it is about some of the driest material you can find. It is written in a fun and enjoyable fashion. Every page had an "AH HA!" moment and I am much more confident in my electronics hobby and profession.
I cannot recommend this book enough and I would pay triple just for the section where the author walks through a couple sample circuits, describes each component's function, and what would happen if that component failed.
Two things at the outset: 1) I've written 18 programming texts so I know what it's like writing a technical book which makes my perspective likely different from most readers, and 2) I've been a licensed amateur radio operator for over 60 years, and that's why I bought this book...I want to start fixing my own equipment.
Pros:
I know how hard it is to discuss technical material in an understandable, yet interesting way. The author has done a good job of that. He's honest about the tools it takes to really fix something beyond a simple fuse replacement. Chapter 6 has some guidelines on using those tools.
Chapter 4 is a great chapter on how to approach the problem of fixing electronic equipment. The Zen of electronic repair is quite similar to that of debugging software, so I felt right at home with that.
There's a chapter devoted to various electronic components you'll encounter and the common uses for each. This chapter is much better than most I've seen.
Chapters 10, 11, and 14 are the best chapters from a use perspective, in that it defines the major components of most electronic systems and then tells you how to track down a problem. Chapter 14 breaks these techniques down further by devices (e.g., audio system, camcorder, computer, etc.) I think these are well done.
Cons:
He starts the book with several stories of repairs that he had to do and how he "sleuthed" them to a solution. These stories were both informative and entertaining...not an easy combination to pull off. Alas, there were too few of these. His knowledge and experience are obvious from his writing, but the stories were enjoyable to read while learning. I would have liked to see more.
I was hoping for a table of problems, and the associated method of attack on the problem (e.g., measuring voltages, injecting an audio or RF signal at such-and-such a point), and the likely culprit of the problem. There is a lot similar to that in narrative form, but a summary of issues pointing to details in the chapters would have been great. In ham radio, there are many things that can go wrong, and a table of problems/solutions like you sometimes see in an operator's manual, would have been very useful. Again, probably more for my needs than most readers, but the book fell a little short of expectations because something like it was missing.
Obviously, I enjoyed the book and felt that I learned things in the process.
Right off the bat, I like the book. It introduces you to all the tools, both necessary and "nice to have". You learn what to get, how to shop wisely, and how to use them (of course). This takes up quite a few chapters. Then you get down to business. You learn about electronic components and what things are likely to go wrong in the devices you are most likely to come across. With this knowledge, electronic devices become comprehensible equipment instead of mystery boxes. That's what I like. I like to learn about things. I like to take the mystery out of things.
Now for the bad, which has nothing to do with the book. The bad thing is that acquiring all the necessary, and a good chunk of the "cool" tools, will run into the thousands. You also have to have a dedicated work area, so if you are short on space already... Finally, it takes time to troubleshoot and repair things. If you are retired, no problem. But if you have to make a living, it will be much cheaper and easier to have someone do the repair for you or just buy a whole new item (depending on the problem).
If you get satisfaction from learning and tinkering, get this book. If you are curious about this sort of thing, but can't afford the tools, space, or time, you might get the book anyway to learn what you can. If you just want to "save money" by doing your own repair work, I'd say do it the easy way. Pay for repair, or buy new stuff when your old stuff poops out.
