[sci.electronics] Advice on getting started...?

sean@eleazar.dartmouth.edu (Sean P. Nolan) (09/27/89)

Hey there .....

I'm looking for advice from people here on how to get started actually DOING
something with electronics. I've read a few books and have a pretty good 
understanding of what various components (discrete and within ICs) do and how
they work. But I'm kind of at a loss as to what to do now. Picking up random
schematics, I can get the general jist of what's going on, but wouldn't be
able to sit down and design a circuit for the life of me. All real-world 
projects have resistors and capacitors flying all over the place in seemingly
random places.  Hmmmmmmmmmmmmmmm.

So, if anyone has any good advice, I'd appreciate getting it. Things I'm 
looking for include how to pick and build power supplies for circuits, how to
figure out resistor placement, etc etc... just about everything and anything.

Thanks...

--- Sean

The best non-mathematical treatment of practical electronic "design and 
analysis" is THE ART OF ELECTRONICS, 2nd Ed., Horowitz & Hill, Cambridge
University Press, 1989, in my opinion. This is appropriate for freshmen
university students with a couple of years of high school science.

There is also the old standby, THE ARRL HANDBOOK (FOR THE RADIO AMATEUR),
yearly editions, at a slightly lower level of "difficulty."

I'd say someone who has gone through these two books, especially the first,
has a better grasp of practical electronic design than the average newly-
graduated electronics engineer, minus the math of course.

There is also my old favorite: HOW TO BUILD AND USE ELECTRONIC DEVICES
WITHOUT FRUSTRATION, PANIC, MOUNTAINS OF MONEY, OR AN ENGINEERING DEGREE, 2nd
Ed., Hoenig, S.A., Little, Brown, & Co., 1980. This book may be out of print.

I would second those two recommendations, and add a third.  If digital stuff
is what you want to get into, you could do a whole lot worse than to get
Don Lancaster's CMOS COOKBOOK.  It is getting a little old, but I don't know
of anything even close to it for getting into digital circuits.  (His TTL
COOKBOOK is badly dated by now but also worth reading.)

I "got started" when I received a Radio Shack 100 in 1 (or 101, or 120)
Electronics Project Kit.  Its not called exactly that, but the RS guys will
know what you're talking about.  

Its a prototyping box with various components, and a book of projects.   They
vary from a radio transmitter to a LED display driver, etc.  Fun stuff.  And,
you can easily modify the projects or build your own.

National Semiconductor publishes a very good little book entitled
"Intuitive IC Op Amps"  by T. Frederiksen.  It will tell you all you ever
have to know about closed loop circuits.  It also has oodles of
application info.  Try it, you'll like it.

I got started, 15 years ago or so, by picking up some 74XX ICs and a breadboard
from Radio Sh**, reading "The TTL Cookbook" (By Don Lancaster, I believe)
and some 555 (timer) technotes, and just plunging in by doing simple
things.

Now I'm an experimental physicist making $12,000 a year and living in Pasadena.

Since TTL is showing its age, you may want to use CMOS instead, but
the 555 is still a great chip for making an LED blink.  You don't have to
know how to bias a transistor (I didn't learn until 6 years ago), but
Op-amps are easier anyway.  As long as you laugh when someone mentions
"Ohm's Three Laws", and have a rough notion of what a capacitor does,
you are ready to begin learning to use ICs.

	Wow!  They don't pay too well at CalTech, do they??  :)

	I hope that's a typo - at UCLA, our grad students in physics (like 
me!) get paid more than that...

				No :(

I wish it were a typo.  As a 5th year physics grad student that's what I make
as a research assistant.  In my last summer job, five years ago, I was
making about 2.5 times that salary (in 1984 dollars), but the company
I worked for paid summer hires at 3/4 entry-level scale.

At least I will get a sheepskin out of it.  At UC Berkeley, they use the
first-year physics class as disposable people.  They pay them starvation
wages for two years to work as teaching assistants, and then they
flunk out half of them.  (One of the reasons I decided not to go to
Berkeley.)

This doesn't really have anything to do with sci.electronics (except
that it explains why almost nobody goes for the PhD in E.E.) so
follow-ups should go to sci.physics, with copies nailed to the dean's door.
