Chop wood, carry water. Using cookbook circuits is kind of like that zen story. You come full circle. There's little enough honestly new in electronics that almost anything you do will look cookbook to an outsider. Designing actual

Radio is the traditional hobby application and is a good place to start. The ARRL publications vary in quality and level but are generally pretty good. You can go as deep as you want into RF design at the hobby level as a ham. It's

One of my mentors said "read all the hobby magazines, you never know what you might learn, sometimes they pick up new technology faster than industry". So did Bob Pease in one of his columns. But yeah, there's a lot of groa

Just wait till you put a bigger load on your fet than that 100K resistor, try to PWM it, and discover the Miller effect.

Agreed. In defense of Forrest Mims, though, his circuits generally work and are simple, to-the-point approaches.

The Art of Electronics was originally written for science (physics) students who intend to become experimentalists. Experimentalists traditionally build their own instruments - i.e. if you can just buy something to do a measurement, why sh

You could also get nicely printed (engraved I think) log paper (in a number of different scale configurations) for much longer. Also from K&E. Like printed Smith charts, though, it has gone the way of the dodo - people that need one j

Yes, but knowing assembly language won't help you through complicated C declarations of the sort used to demonstrate cdecl.

Ah yes, Phoenix. The thunderdome of the United States! Where, unlike anywhere else in America, there is no public education, no food stamps, no Medicaid, no Section 8 housing, no disability insurance, no Social Security or Medicare...

You can think of a two-income family with union jobs and pensions as the bottom rung of the upper middle class. It's more clear than not "rich" .

Someone else posted a great link explaining why you probably don't want tclsh or wish as your login shell. Today zsh or fish is the better bash, really. Here's another dead end unexplored though - dtksh! https://www.b

Yeah, thanks to C pointer syntax, there's a big faction of programmers that think that understanding indirect addressing is a major intellectual accomplishment. I don't have anything better to offer though - C pointers make a whol

The only problem with BASIC is that it's kind of gross scaled up for medium-sized applications. It's downright charming at the Tiny-BASIC, VIC-20 BASIC, or even BASIC-52 level though. LOGO has real depth, an elegant syntax, and t

Right, because you might die of old age before your bankruptcy proceedings are over in Germany, and your debts can then be passed on to your heirs. But you're right about everyting else, especially comparing to California.

What's the advantage of soldering a module in as opposed to soldering a microcontroller? What is the advantage of laying out a new module as opposed to laying out a new integrated board? Why do you think the level of modularity alrea

At the time I really didn't care for that neo-victorian junk drawer aesthetic but now it makes me nostalgic too.

We'd just be having a gear shortage or something. The people who can build mechanical clocks are either working on other things or making high-end wristwatches. There are still people inventing new watch movements.

Relays drop in price with volume much faster than many other parts. I'd believe it if it were 12v "sugar cube" types, which a quick search tells me it probably wasn't.

Because it literally costs money to separate PCB material into separate boards, so there is a minimum cost associated with adding an additional bare board to a design. Which is more than you think. Connectors also cost money; often more th

I read long ago that the SCR-584 was prototyped with washing machine parts, but the actual quote I found was "We would buy a washing machine if it would bring a quicker result."

I have, in a drawer in my office, the motor and an absolutely fascinating motor drive board from an Electrolux washing machine that a colleague brought in. It appears to be a three-phase variable frequency drive (VFD) with an elegant archi

I had a number of the IIIxe in the late-middle days of Palm. They were a little fragile and tended to get busted up. I had one whose switch-mode supply hummed audibly- that one ate batteries. Maybe you had better hearing than me or worse
