Ok so I have an old P4 that I was going to use to make a sound card Oscope and Function Generator with, but then I got to thinking that this might be the perfect task for my Pi. I figure it should be possible to do it through the gpio pins. I know I need a gert board. I'm to new to electronics to tackle this alone so I am looking for some help in trying to accomplish this. Feedback, Ideas, Thoughts?
