that powers it by using the lateral
resistance of the water.
I found that amazing. It makes
me suspect that there should be a
way to play gravity against
magnetism for a net gain. Haven't
figured out how to do it, though.
I just read the March 2014
Developing Perspectives editorial,
"Know Your Basics." I have been
struggling with trying to master the
basics for a long time. I have done
nearly all of the things you
mentioned in the article, including
reading the Mims books and the
Horowitz and Hill book, and even
taking a linear circuits class at a
community college. However, I still
feel like there is a giant rift between
knowing the basics and being able
to understand a lot of the regular
articles in NV. I don't know how to
get from understanding LRC circuits
to programming PICs, AVRs, and
Propellers. I guess what I'm asking is
if there is a single book/website/etc.
to take me from classical stuff to
modern microcontroller-based stuff.
Thanks for your time and putting
out a great magazine.
Single source ... Wow! A great
mentor would do. That's what did it
for me. You won't find that in a single
book, however. If you want to learn
microcontrollers, then you need to
work with one. I'd pick up an
Arduino Uno and work through the
examples. The official website is
excellent. My 12 year old nephew is
doing well with it.
Spelling It Out (Please!)
By usual tables, I am an oldie. I
can do Ohm's Law problems with
dispatch, and recall the smell of
heated rosin, the glow of a pair of
807s in push-pull, and even the 40
meter CW sounds in the early hours.
However, try this:
"'Twas brlig, and the slithey toves
did gyre and gimble in the wabe,
All mimsy were the borogroves,
and the mome raths outgrabe."
That ditty from Lewis Caroll was
not meant to be understood — at
least not by ordinary mortals.
On the other hand, if you were
trying to keep up with electronics
and dutifully read — or tried to read
— your monthly magazine, an
