Gen_Eng 295, Fall 2017 -- Makerskills


Eligibility – First year engineering undergraduates in all disciplines.  



What do students say about this class?


Here are the CTEC comments about it from 2015.

Here are the CTEC comments about it from 2016.


Note: Makerskills Fall 2017 will be somewhat different from the previous two years. Previously it was almost all electronics, interfacing, and programming for embedded control of hardware in matlab and arduino. In Fall 2017 the course will still have these components, but with less emphasis, and more time will be spent on other makerskills including CAD and 3d printing, laser cutting, solderboard construction, and design. Our work will involve sensors and motors.


Why take this class?


Embedded computing is what makes our smart gadgets smart. It is code (software) that interfaces through electronics to read from, and act in, the physical world. Sensor inputs can be thermometers, accelerometers, switches, force gauges, microphones, touch screens, etc. Outputs can be lights, sounds,LCD displays, motors, and many more.


Connecting software to the physical world is a great way to learn programming! You will learn programming, and interface your programs to the physical world using the electronics that you build. You will learn electronics, designing and building you own circuits. This class will complement the programming that you will be learning in EA1 (Gen_Eng 205-1). Both classes use the Matlab programming language.


You will gain enabling skills, that are in high demand in your design courses, extracurricular teams, and often in research participation as well. In the hobbyist world, proficiency in embedded computing and electronics is a highly respected "maker skill".


In 295 you will design circuits with modern electronic devices such as operational amplifiers and digital logic chips, interfaced to sensors and actuators. You will use test instruments, especially the oscilloscope and voltmeter, and you will design, prototype, and debug circuits on protoboard. We will first use the Matlab programming environment, which lets us use laptop graphics, and later we'll do some arduino programming as well. ]


295 is a lab course in the sense that it is hands-on and emphasizes the development of design and diagnostic skills both in electronics and programming. These skills will be developed in class and also in homework. Because portable equipment is used, there is no need for a scheduled lab.





Instructor – Prof. Michael Peshkin


Class size – 28


Schedule – MWF, 12:00 to 12:50 PM, F281 Tech active classroom


Text – no textbook is needed; video, online, and print materials will be provided.


Prerequisites – Concurrent enrollment in Engineering Analysis I (Gen_Eng 205-1, a.k.a. EA1).  EA1 and 295 both use the Matlab programming environment; EA1 in the context of linear algebra and 295 in the context of electronics interfacing.


Credit – Gen_Eng 295 counts as an elective in all engineering departments.


Materials and fees – You will need a laptop computer, running Windows or Mac OS, every day in class, and also for homework.  


Format – Class sessions are a mix of lecture and guided work sessions. Homework is due at the beginning of most class days. There will be two one-hour in-class tests and a two-hour final exam.
