Fundamentals of Audio and Music Engineering: Part 1 - Musical Sound & Electronics [Coursera] (FREE)
Found an interesting and relevant online Coursera course beginning in a few weeks: "Fundamentals of Audio and Music Engineering: Part 1 - Musical Sound & Electronics" via the University of Rochester (NY).
It'll be my first time taking it, so I can't comment on how good it is and such, but even if you're an DIY wizard, it should be an easy, fun course and you'll get a certification upon completion ;). Nice little thing you can add onto your CV/LinkedIn profile, no matter what your major or occupation will be or currently is..
Some course info:
Begins MONDAY February 3rd, 2014.
6 weeks long.
English w/ English slides
Supposedly you'll be able to build a simple guitar amp.
I've taken one Coursera class before, and the video lectures are usually fairly short and homework is quite easy (though the easiness will vary with knowledge & education). It's pretty much a very easy way to get a guaranteed "course certification" (totally viable nowadays).
See ya in class! (hah)
