This thing is a tome. And I like it like that. Functions as a nerdy coffee table book when not in use.

Pre-ordered mine(hardback). Yeesh....I have no impulse control because this looks like so much fun,

> It gives real answers but doesn’t demand a year of calculus beforehand.

Oh yes, these kinds of shortcuts have always worked great.

My objective has often been to build & test as many experimental circuits as I could in the shortest amount of time.

One of the real good shortcuts is to just start soldering parts together according to a plan in your head, without taking the time to make a schematic drawing beforehand or do any advanced calculations.

There might be more emphasis on the properties and ratings of each component this way, this is not something to skip over, you should be very familiar with each component you use. Well in advance, and loads of hours of component study needs to be behind you, otherwise you may not do too good at just whipping something up on the bench that's electrically sound to begin with.

As pointed out, with math it can be the same way.

If you just want to quickly start picking up parts and soldering them together right away without doing any advanced calculations, the best shortcut is to have already become quite familiar with the equations including calculus when necessary, so you can bring to bear endless hours of mathematical study and use it to intuitively guide your soldering iron for every hour at the bench.

Edit: upvoted because your message should not be less than neutral, not greyed out at all. Obviously, I'm on the fence, sometimes I use math, other times not at all ;)

They have. When you need more math -- and you will if you stick with this business for very long -- it'll usually be obvious, and you can pick up those skills then. It's never been easier.

Ha, Ha, True.

That was a silly statement by the author; just say that this is "less theoretical" and not a textbook.

Looked at the contents/sample chapter and it seems just like many of the books published by make magazine.

Just ordered. Love these kinds of books. Any others like this one people are aware of?

looks like a great book, but the cover is hard to look at after having a few painful soldering burns

Got mine. And I'm a former EE. Looking forward to it, maybe inspire my daughter a bit.

It would be nice to see a similar book devoted to sensors. Anyone have recommendations?

PE4I (“Practical Electronics for Inventors”) has a whole chapter dedicated to sensors

Make: has a 3-vol series Encyclopedia of Electronic Components one of which is on Sensors - https://www.makershed.com/collections/books-on-electronics/p...

Also see Sensors and Signal Conditioning by Ramon Pallas-Areny and John Webster for a theoretical combination treatment.

The artwork on the cover should come with a health and safety notice :D

I like the pop art style. But what is she going to do with that soldering iron - stick it up her nose?

Maybe it should look like someone in a Western movie blowing smoke from a pistol?

It is clearly a reference to a smoking gun. I think the cover is beautiful.

That alone makes me think it was drawn by AI. They say it's not...but that iconic pic sits directly in the uncanny valley.

Like the best art, it's left up to the viewer to decide!

Sshh. Her lips are sealed.

It's just a stylistic thing, same with the smoke, which represents heat more so than fumes.

Normally you hold the iron horizontal under the nose and of course don't breathe during the heat test.

And you don't actually kiss the soldering iron until it's cooled all the way down, and usually not unless the experimental circuit you came up with works the first time you plug it in :) So you can relax as intended and unplug the damn iron, without having to keep on hammering til all hours.

One thing she's not telling is the way you should be effective enough soldering using (very inexpensive) uncontrolled soldering irons, that you can eventually solder two pieces of solder together. Before you graduate to a "pro-grade" soldering station.
