Ask YC: Learning circuit/hardware; lab book?

The Art Of Electronics has a pretty nice lab manual that goes with it

I've also found the ARRL handbooks to be extremely helpful

One of the best resources for getting a practical handle on electronics is the ARRL Handbook.

A Peek at Computer Electronics: Things you Should Know

I highly recommend "Designing Embedded Hardware"

another boost for the lab manual for the horowitz and hill's art of electronics
