Lecturer: Alex Sloboda
The course is targeted to freshmen but upperclassmen are welcomed if space is available. The course will be limited to 40 participants with freshmen given priority. Sign up on websis.
Level: U 6 units Graded P/D/F Can be repeated for credit.
Lectures: Mon/Wed Jan 17, 22, 24, 29, 31 Room TBD 2:45-4:00p
Labs (38-600): There are two lab sections, one immediately after lecture and the following day. Students will be assigned to their choice of lab section (if possible).
6.117 is a fun/no pressure introduction to the lab skills necessary for many career fields. No prior electrical engineering knowledge is required - only high school physics. This course is intended for freshmen to get a hands-on introduction to electrical engineering and computer science. On completion of the course, students will have the skills and confidence to use electronics tools: oscillosopes, function generators, multimeters and logical analyzers as well as Matlab. During the course, students will solder circuits, make measurements and build interesting circuits such as an ECG amplifier that allows you to view your ECG on an oscilloscope (actual ECG photo below), a USB powered 1.4 watt audio amplifier and other useful circuits. Students will run Matlab scripts to analyze and plot their ECG. Learn how Fitbit measures heart rate.
The five labs start off with basic concepts and progressively introduces op amps, other analog integrated circuits and moves through digital circuits. In the labs, each student will work at an individual fully equipped lab station. We teach you how to wire up breadboard circuits and how to solder. We explain the theory of operation behind each of the labs. You will build and solder (and keep) a circuit on a printed circuit board (PCB) that amplifies your heart's electrical signal (ECG) and displays it on an oscilloscope or even better on any laptop with a microphone input jack. You will understand theory behind the ECG circuit. You will feed the ECG into Matlab and run scripts to analyze and plot your heart rate. The ECG amplifier is shown below.
In the last lab, you will build a surface mount 1.4 watt audio amplifier. The amplifier is a complete self contained unit, uses a Texas Instruments TPA2005 integrated circuit and is powered from USB. Attach an audio cable, hook up a pair of speakers and you have great sound from your PC.
At the end of the course, you will be able to explain how an iPod and PC works. Completion of the five labs is all that is required to pass the course. There are no homework assignments. We have a great staff to help you in the lab and have a student/staff ratio of 5:1 in the lab. Course consists of five lectures (with lecture notes provided) every other day and five labs. We know you value your weekends - so there are no classes or labs on Fridays!
