CALENDAR ENTRY:

Electrical Engineering Design students will work in pairs on small design projects that will require them to follow a hierarchy of design process which includes general product definition, specifications and requirements, functional block diagrams, definition of specification of functional blocks for circuit level synthesis and implementation, system integration, simulation, or modeling, testing and verification. The small projects are designed to encourage and motivate students to learn and practice the process of design. The course will culminate in a large design project.

Course Description:

The objective of this course is to provide students an opportunity to learn and practice electrical engineering design. Fundamentals of electrical engineering design related to this course will be covered in lectures. Five design labs and design projects are to practice electrical engineering design. Students will work in groups for labs and on their design projects that will require them to follow a hierarchy of design process which includes the following: the general product definition, specifications and requirements, functional block diagrams, definition of specification of functional blocks for circuit level synthesis and implementation, system integration, simulation, or modeling, testing and verification. Five design labs are basically a guided design project to encourage and motivate students to learn and practice the process of electrical engineering design. In the last week of the term, students will demonstrate their design projects as a commercial product to the external reviewers.

Design Labs:

The following five labs will lead to design and demonstration of a small portable emergency light system. After completing a lab, submit a lab report in pdf format on the course website.

1. Design, implement and test a 120V, 60Hz, 10VA, 8-0-8V step-down transformer.

2. Design, implement and test a 120V to +5VDC regulated power supply with input and output indicators and a USB connector.

3. Design, implement and test a PIC16F684 controlled 12V, 7Ah lead-acid battery PWM charger.

4. Design and implement a PIC16F684 based automatic portable emergency light control circuit.

5. Package, verify, demonstrate, and present the designed emergency light system and its product brochure.

Twenty Design Projects are listed below. All projects are based on Intel Galileo board (https://www.arduino.cc/en/ArduinoCertified/IntelGalileo) or Arduino board (https://store.arduino.cc/usa/arduino-uno-rev3) Students will work in groups (2 students per group) on these projects. Select your project and group member before January 11, 2020. All circuits in a project and labs should be built on prototyping boards (i.e. no breadboards are allowed). The finished product should be in a box with appropriate connectors and labels. In the last week of the term, all students will demonstrate their projects to reviewers and present projects overview and technical specifications in a brochure.

Students are expected to demonstrate awareness of, and personal accountability for, safe laboratory conduct. Appropriate personal protective equipment (PPE) must be worn (e.g. steel-toed shoes, safety glasses, etc.) and safe work practices must be followed as indicated for individual laboratories, materials and equipment. Students will immediately report any concerns regarding safety to the teaching assistant, staff technologist, and professor.

ACADEMIC INTEGRITY AND PROFESSIONAL CONDUCT:

Students are expected to conduct themselves in all aspects of the course at the highest level of academic integrity. Any student found to commit academic misconduct will be dealt with according to the Faculty and University practices. More information is available at http://www.mun.ca/engineering/undergrad/academicintegrity.php Students are encouraged to consult the Faculty of Engineering and Applied Science Student Code of Conduct at https://www.mun.ca/engineering/undergrad/policies/CodeOfConduct.pdf and Memorial University’s Student Code of Conduct at https://www.mun.ca/student/supports-and-resources/respectful-campus/student-code-of-conduct.php Individual work is expected of each student. Even if students work in groups, or discuss with others, assignments and reports should be independently prepared.

INCLUSION AND EQUITY:

Students who require physical or academic accommodations are encouraged to speak privately to the instructor so that appropriate arrangements can be made to ensure your full participation in the course. All conversations will remain confidential. The university experience is enriched by the diversity of viewpoints, values, and backgrounds that each class participant possesses. In order for this course to encourage as much insightful and comprehensive discussion among class participants as possible, there is an expectation that dialogue will be collegial and respectful across disciplinary, cultural, and personal boundaries.

STUDENT ASSISTANCE: Student Affairs and Services offers help and support in a variety of areas, both academic and personal. More information can be found at www.mun.ca/student.
