In addition to for-credit college courses, I offer occasional workshops on 3D design, 3D printing, Arduinos, electronics, rapid prototyping and related topics. Materials for those classes and workshops can be found in this section. These are support materials for in-person workshops are are not intended to be complete online instructional units. A few stand-alone presentations and other materials are also archived here. Feel free appropriate whatever you like, although credit is always appreciated. I am available to do workshops, so ask.
