This might be a good place to tack on this link...
In the Project Guidance Forum I made this post:

Next week (July 23, 2012) the Design Mag/Digikey group will be offering a course on Electronics taught by Max Maxfield -- one hour a day. It might be useful to some here -- starting out or otherwise.
They have seminars on programs and error analysis and troubleshooting etc...
probably missed the most obvious forum to put it in too

Guilty as charged -- but not everybody reads them and just dives in with questions. So maybe here is appropriate too...
Regardless, thank you for reminding me.
I'll bump this up again... Since more are asking...

Starts Monday at 2PM NA eastern time
and here...
I will add this reference as well.
A lot of tutorials here about all aspects of electronics.

And lots of questions about voltage dividers:

The course at design news has started -- it seems to cover the basics -- though at high speed. As each course is held it is archived almost immediately. There is a presentation you can download. If you do not have PowerPoint (PPT) -- download OpenOffice -- the latest version works with all the PPT versions used..
Did anyone attend? If so was it useful?
