Re: [ATM] stepper motor circuit with autoguide for 148 tooth gear??

I am intrigued by the "Elektronik för Alla" (electronics for all) books.  In a similar way I have encouraged my kids to read a popular book on a subject before they read a technical one as they are likely to start with the "big picture" and better able to absorb the technical details when they come along.  My own way of learning a new subject is to read 3-4 books on the subject straight out - then see where that leaves me.  (I'd like to see a page or two of the books if you wouldn't mind).
   
  George Anderson gave me some very helpful information about motor controllers and calculated how I might change a crystal in Covington's circuit to match my mount gearing (his being able to do that feels like magic to me!)  I will be trying to make one of these circuits I think.
   
  I also appreciate Bob May's advice on his web site to get someone that does electronics to help with the drive controller project - very practical.  
   
  Electronics has always been a missing part of my hobbyist  background (I have done some computer programming in the past, some machine work, a good amount of wood working, mechanical stuff, and a modest amount of optics) but electronics - NOT MUCH!

Come to think of it (I sent email off list earlier to Gil), there is
an excellent set of 3 books here in Sweden called "Elektronik för
Alla" (electronics for all). Since Gil is a psychologist, he might
appreciate these books. I have never seen anything like these in
English print, and they wonderfully exemplify the Scandinavian
teaching style (math and physics textbooks are similar). They can
be characterized as having minimal words and many simple real
world examples. I took some courses when I first moved here and
found myself passing with rather good grades despite not knowing
the language. I had a translation dictionary of course, but I did
not get any help from native Swedish speakers. Somehow, the
simplicity in these books allowed better focus on the main points
which stuck a lot better in long term memory.

I would also be interested to know about similar books in English
print, otherwise, I can scan a couple pages to exemplify books
here.
