Does anybody know of book that contains a bunch of circuits, analog or digital, with explanations on how the circuit works. I already have Forrest Mim's Circuit Scrapbook. I am looking for something like that but more complicated stuff.

 

Try 310 Circuits from Elektor magzine

 

Modern electronic circuits reference manual
By John Markus, McGraw-Hil

 

you could always delve into the world of hobby robotics and read these books >> The Robot Builder's Bonanza: 99 Inexpensive Robotics Projects, volume I and II.
