Books On Electronics For the Lay Programmer? 335
leoboiko writes "I'm a computer scientist and programmer with no training whatsoever in hardware or electronics. Sure, we designed a simple CPU (at a purely logical level) and learned about binary math and whatnot, and I can build a PC and stuff, but lately I've been wanting to, you know, solder something. Make my own cables, understand multimeters, perhaps assemble a simple robot or two. Play with hobbyist-level electronics. How does one go about educating oneself in this topic? I've been browsing Lessons in Electric Circuits online and it's been helpful, together with Misconceptions About 'Electricity' which went a long way in helping me finally to grok what electric charge and power actually are. I've reached the point where I want an actual dead-tree book, though. Any recommendations?"

It's pretty useless as a display of how to set the bias current for a class A amp for an obsolete transistor. You know, vocational school "training".
But its great for explaining the thought process of, "I want an amp" "I need the following characteristics" "guess I want a class A" "how should I design one?" "here is an example". Yes the last step, the example, is somewhat useless now, but the best part of the book was the other steps anyway. It provides an "EE education" as opposed to "vocational training".
It's like the difference between "history" and "journalism". Or "education" and "training".
Don't go into AoE expecting the wrong thing, or you'll be disappointed.
Go into it with the attitude that it's "EE in 24 hours" and you'll be unhappy. Go into it with the attitude that its a guided puzzle book or a philosophy of EE work, and you'll be happy. It's kind of like Knuth's TAoCP series, in that way.

There are very few technical books that are as well written an clear as Art of Electronics. A robotics book might be more "essential" if you are interested in building a robot, but very few of them will extend your understanding and mastery of robots specifically as AoE will extend your understanding of electronics in general.
"Practical" doesn't just means "arts-and-crafts." Theory is "practical" too, when you are faced with a problem that requires an original solution. AoE was not, if I recall correctly, written with the EE student in mind. It was written for people like experimental scientists from whom the ability to understand and design circuits would be a great practical advantage.
If you want to build other people's designs, then by all means restrict yourself to building things that other people have designed or snapping together modules, you can get by without really knowing much about how electronics works. I expect that most robot hobbyists only have a rudimentary understanding of electronics theory, and that's fine for them. But it certainly won't hurt to be able to analyze circuits even design them, and if you avoid AoE because it is not "practical", you're cheating yourself out of one of the best tech books ever written.

Much as you can't learn to program well without looking at programs more complicated than you'll find in any textbook, you need to study real world circuits.
Whether you want to do digital stuff or analog, it's worth your time learning the analog stuff -- digital systems tend to break as a result of the underlying analog problem of circuit design.
For example, Wikipedia has the internal schematic for a 741 op amp [wikipedia.org] along with a decent explanation. Once you understand the function of every one of those transistors, you'll be able to really understand why it has both a gain-bandwidth limit and a slew rate limit, and what the difference is.
The best source of real-world circuits I've found is the application notes and example circuits in data sheets published by manufacturers. Since they need the resultant circuits to work when engineers build them, they don't leave out the random extras that textbooks often do. Does that MOSFET need a gate resistor? A circuit in an app note will probably say, whereas an example diagram might well not.
If your goal is to learn more in general, as opposed to solving a specific problem, I'd pay more attention to the author than exactly what they're writing about. For example, I can't recommend Jim Williams' design notes highly enough -- he's both an excellent engineer and an excellent author. Making Shakespeare [linear.com] a citation is the sort of thing that keeps his writing lively and interesting. Or rating circuit complexity in baby bottles [linear.com] as a measure of how long it took him to design and debug it. And, of course, he often goes into great detail about the *practical* considerations involved in precise, high-speed analog work -- especially as it relates to working at the lab bench, rather than with professionally printed PCBs and the like.
I'm sure others will have excellent textbook recommendations. They're an important part, but only a part. Add some analysis of real-world circuits that you'll find in application notes, and a bunch of fussing around with actual silicon and a scope, and you'll be well on your way.

"arrl handbook" any recent year is good enough no need to buy the latest 2008 version
"TTL handbook"
"art of electronics"
"troubleshooting analog circuits" by Robert Pease
Sure, AoE is two decades out of style, and TTL Cookbook is even older.
But the logical thinking required and the basic principles will not change.
Furthermore, today's stuff didn't just spring into existence from nothing, it was deve

Get an analog scope for your first one. They are dirt cheap used and will give you more insight into how oscilloscopes work.
Because most of todays new parts are surface mount, you will eventually want to get a quality soldering iron. Trying to solder

At that level, the Forrest Mims books that others have linked to would be the right choice. AoE was written for practicing scientists and grad students -- in other words, for people in other scientific fields besides electronics. It is not the most
