Fall, Spring | Undergrad | 6 Units | Prereq: Physics II (GIR)
Practical introduction to the fundamentals of electronics in the context of electro-mechanical systems, with emphasis on experimentation and project work in basic electronics. Laboratory exercises include the design and construction of simple electronic devices, such as power supplies, amplifiers, op-amp circuits, switched mode dc-dc converters, and dc motor drivers. Surveys embedded microcontrollers as system elements. Laboratory sessions stress the understanding of electronic circuits at the component level, but also point out the modern approach of system integration using commercial modules and specialized integrated circuits. Enrollment may be limited due to laboratory capacity; preference to Course 2 majors and minors.
Fall 2020 Update: Fully Remote Hands-On Classes - 2.678 in the fall will be taught remotely, with synchronous class meetings that will be available after-the-fact as recordings, supplemented by extensive video demos and explanations. We are planning to emphasize hands-on work and design exercises. For labs, students will get a kit of parts at the start of the semester, including a multimeter, USB oscilloscope, soldering iron, and parts to construct all of the labs remotely. The labs have been reconfigured from previous semesters and vary between 1 and 2 week projects. We will have a pre-recorded "lab intro," a Slack channel for lab questions, open lab office hours and "page an instructor" hours for support. Some example projects this semester: * Soldering: Assemble & test a complex printed circuit board that will serve as your work surface for the rest of the semester. * Audio Amplifier: Build an audio amplifier from discrete components. * Intro to Arduino: Including closed-loop control of a small thermal plant. * H Bridge: Build a motor driver from discrete components and use it to perform closed-loop torque control of a motor.
