I was not going to reply to the positive-negative thing
but I feel I must put in my 1 cent worth (I dont have 2 cents).
Anymore I don't care which direction it goes.
There was a time when I HAD to know every detail about
how something works and I would not advance further until
the mystery at hand was solved. Looking back in hindsight
I found this to be a happerance to my advancement.
I used to program exclusively in assembly or machine code.
I had complete control over what was going on. Then as the
C language came out I was totally annoyed that I did not
know the underlying machine code for the printf function.
Though the function worked fine, if anything were to go wrong,
I wanted to know the complete workings of the function so I
could fix it. Today I use functions without thinking twice.
I investigate when something isnt working, but I dont bother
wonder WHY something works, it just works or it dont.
It's the same with electronics. I know what an op amp is and
I know how to get it to work from me mostly learning by circuit
examples. I never learned all that extreme math that is taught in
the op amp books because that would turn me off to the fun of
electronics. I mean a hobby is supposed to be fun isnt it?
I just know that I have an audio signal that I want to amplify.
I look at a sample circuit, build something close, scope it out
and tada amplified signal! I beleive too much strict adhersion to
engineering rules depletes inventive innovation.
I've smoked my share of parts but what a great teacher!
I think it is even possible to use a matrix of 555's as
a stove burner!
Anyway, once you did decide to follow one convention or the other
of the positive/negative delima, someone would come along and offer
you the 'ether' theory of electronics and you would have to abandon
your beliefs anyway!
I hope your wanting to be more technical in electronics does
not take away from the excitement and fun of it.
