This is an outstanding website, both for information contained therein, and the way it is presented.
A quick glance through a few pages of this site will not do it justice. Try and budget at least a half hour to fully get the feel for what it is about.
Perry Babin, the electronics tech who built the site, says he has thousands of hours invested in it, and maintains it as a hobby. He is very good about answering emails promptly, too.
This is, IMHO, a terrific place to while away an afternoon.
