Ask HN: Electrical Engineering for Hackers?

I have a bachelors degree in IT (Computer Information Systems). While I love computers I am fascinated with really making things. I have read a couple Arduino books, and built quite a few projects with Arduino, some from instructions some of my own doing.

However, in my most recent project I feel like I have started to reach the end of basic electronics knowledge. I know that many people spend their entire academic career studying electrical engineering and that it isn't something I can teach myself overnight.

That being said can any EE's out there recommend a good primer on the basics (beyond just circuits and the other super basic stuff) of electrical engineering? Whether it be books, web resources, online classes, or anything else I would be very interested, and greatly appreciative.

Any other electronics/Arduino hackers out there? How did you teach yourself and bootstrap your projects? I'm interested in any and all information.
