What I think DIY Class would make me able to do

I had not thought of any appropriate use of taking this class until I actually got introduced to the stuffs we do here...I still have a lot of questions of what I will be able to get out of this class by this semester
I got to be introduced to the electrical configurations of the things what I have always used and never wondered how it works. Now besides knowing how the electric stuffs like Microphones and speakers works, I get to build it from the scratch. Of course parts of it should be bought from elsewhere. I get to make weird and cool sound out of those things. I am hoping to have a lot of information gathered to make some cool stuffs of my own.
