The magazine widely available down here is Silicon Chip. Their
projects are generally for those with intermediate or advanced
skills in understanding and constructing them. Explanations of
how critical sections work are included, but not right back to
basics. eg an op amp is said to have a gain of 10, but not why
it has a gain of 10. Similarly they wouldn't say why an LED has
a particular value resistor.

If you look at a recent article, like the Digital Reverb And Echo

http://www.siliconchip.com.au/Issue/Browse

using a PIC32 and codec IC, it would be tedious to explain
every single component choice. However, the article for the
Speed Controller For Universal Motors (PWMing mains with
a PIC and IGBT, very good) does require, and provides, more
depth, and I do think SC have a fairly good balance between
need-to-know and just-make-it.

If you're really interested in electronics then there are plenty
of good resources to look at on-line. ETI back in the pre-web
80s had regular 'cookbook' articles, and they were always very
helpful..

At a modest level I'm involved with a NZ web site that helps
schoolkids develop their electronic skills. Referrals to Ohm's
Law are regular. A post I made yesterday explained in detail
how to reduce the heat of a 7805 dropping a 12V supply to
charge a phone, all based simply on V=3DIR and P=3DIV.=20

And there is always guidance needed, like reminding them not
to blindly follow what some guy on the web did in his circuit,
and that there's a Why as well as a How
