[sdiy] Awesome web resource

[David G. Dixon]

Hey Team!

I just came across an awesome web resource, "Lessons in Electric Circuits"
by Tony R. Kuphaldt:

http://www.faqs.org/docs/electric/index.htm

I was interested in ADC circuits, and Volume IV, Chapter 13 was extremely
informative: easily the best and clearest explanation of all the various ADC
circuits that I have ever encountered.

Check it out!
