Not directly audio/music related, but it does look interesting. The focus of the course is on the interface between analog and digital -- sensors, transducers, actuators, etc. So there's some crossover to a lot of the stuff that's beginning to be more prevalent in effects.
The project for the course is supposed to be on building a robot. It's based on the MPS430 microcontroller which is the processor in the EHX expression pedal I just picked up. I think they said the parts kit for the robot would be about $50 US.
I'm thinking about using the processor in a non-audio project, so there's a pretty good chance that I'll try to do the class.
The pre-reqs for it are supposed to high school level algebra.

Looks interesting! Thanks for posting. I have my hands full class wise at the moment but I'm trying to put together a list of these types of classes for when my schedule allows.
