I'm working through the first workbook of Forrest Mims course in the Radio Shack Lab.

One of the fist circuits uses a 555.

I've found some decent web sites describing the operation of this chip but sure would like more recommendations...

 

How about here?

Chapter 8: 555 TIMER CIRCUITS

LEDs, 555s, Flashers, and Light Chasers

The 555 Projects
This has some projects that haven't made it into the book yet. If you haven't twigged to it I like making do nothing circuits to teach and writing the articles.

Bill's Index

I have also made resources for those who want to do it themselves.
