I'm preparing to teach an engineering survey course to high school students this summer. The students requested a soldering project and since I have limited electrical engineering experience I am having them build a simple speaker. I am using a design posted on the Make Magazine site (http://makezine.com/projects/make-34/monobox-powered-speaker-2/#.UMIo3JPjn74).
If I understand, this design takes a signal from a stereo audio jack and shorts the two terminals and uses one signal. I'm trying to reduce the cost of the project since I'm making 60 speakers. Can I wire a mono cable with a 3.5mm plug directly to IC socket? I have a bunch of dual plug cables I want to just cut in half. If so, can I eliminate R1?
I've attached a pdf of the circuit diagram.
