An introduction to prototyping and design of electronic systems, this course introduces students to the theory underlying the phenomena to be considered when implementing a design. Even seemingly simple design decisions have interesting physics driving considerations made (potentially) across the entire design, and this course aims to provide students with the means to engage with those phenomena intentionally, intelligently, and effectively. Emphasis is placed on developing a first-principles understanding of these phenomena, their effects, and how they drive design decisions at every level.Fundamental concepts in electronic device design, such as the practical aspects of driving loads of varying types , reading sensors, layout best practices, etc., will be covered, with extensions into the basics of simple mechanical design (form factor, packaging, fasteners) and computer engineering (configuring microcontrollers, FPGAs, memory considerations). By developing a theoretical foundation grounded in practice, students will be able to determine dynamically the best approach to take when interfacing with an arbitrary transducer, meeting a given requirement, the properties and considerations associated, and what actions to take to maximize the efficacy and robustness of their designs.As an introduction to primarily electrical prototyping and board design, this course introduces students to using CAD tools (both electrical and mechanical) for schematic capture, board design, and basic parametric 3D modeling. While specific tools will be used, the specifics of those tools are not the focus of the course.Course deliverables include design documentation, physical prototypes, and source code (where applicable), with the Final Project deliverables take the place of the final exam. No prerequisites are required, but exposure to design software, general fabrication, and most any programming language will be beneficial.
