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 will be covered in class. Five design labs and design projects are to practice electrical engineering design. Students will work in groups in the lab 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 external reviewers.

 

Evaluation Scheme:

 

Five design labs (10 weeks)    35 %

      (35 = 5 x (Lab => design = 1 + implementation = 2 + verification = 2 + report =2))

Design project                         40 %

   (40% = (design=8 + simulation & analysis=4 + implementation=8 + testing = 7 + finished product=5 + final report=8)) 

Design projects final demonstration and verification to external reviewers       10 %

Midterm test  (March 15, 2012)       15 %

 

Design Labs:

 

The following five labs will lead to design and demonstration of an emergency light system.

  1. Design, implement and test a 120V, 60Hz, 10VA, 8-0-8V step-down transformer.
  2. Design, implement and test a 120V to +5V regulated power supply with input and output indicators and a USB connector.
  3. Design, implement and test a 12V, 7Ah lead-acid battery PWM charger.
  4. Design a PIC16F684 based automatic portable emergency light control circuit.
  5. Package, verify, demonstrate and present a product brochure of the designed emergency light system.

 

Design Projects 1 to 20 are listed below. Students will work in groups (2 students per group) on these projects. Select your project and group member before January 10, 2012. 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 and present the project overview and technical specifications in a brochure.

Course Schedule:

Lectures: Tuesday and Thursday, 2:30 to 3:45pm in room EN4034

Labs and Projects: Thursday and Friday, 9:00-11:50am in room En1021/En1038B

(During a lab session, half of the class will work on a design lab and the other half will work on design projects)

Office Time: Tuesdays 9:30am to 11:50am (If I am in my office (En3062), students are also welcomed anytime)

 

Project Deadlines:

 

Part 1 (8%) Design: Complete literature search about your selected project and sketch the first version of the required circuit and the package. On or before January 20, 2012, submit a primary design document on the course website in pdf format. Document should contain a description and objectives of your project, system block diagram and a circuit that you plan to build. Also include in the document some package details, system design specifications and list of task assignments within your group.

 

Part 2  (4%) Simulation and Analysis: Complete the following tasks and submit a pdf file on the course website on or before January 31, 2012. Simulate / sketch your circuit in Multisim; determine the power requirements of your circuit and design the required power supply; submit a list of components and get all required components from the Lab En1020; select a smallest possible box that will house all your components and connectors including the power supply, also include a sketch showing how your final product is going to look like including a software flowchart and GUI if needed.

 

Part 3 (8%) Implementation: Build your system on a prototyping board and show a working prototype system with a first version of software/ PIC-code to the instructor or to a TA. Submit 1-2 photos of your prototype system and a brief progress report on the course website before February 24, 2012.

 

Part 4 (7%) Testing: Demonstrate to the instructor a complete working system with final software/PIC-code before or on March 9, 2012. You need to show a working system with a programmed PIC controller /PC with its power supply in its package. The system should be working as planned and documented in part 1 & 2. Also submit a brief progress report on March 9, 2012 about your system test results as demonstrated, listing still missing features if any and your plan to complete the project.

 

Part 5 (5%) Finished Product:  On or before March 23, 2012, demonstrate to the instructor a fully working system and software in its finished form and in its labeled package. All group members should be present during the demonstration. On March 23, 2012, also prepare and submit on the course website a 1-2 page brochure of your product. The brochure should contain one photo, product features, specifications, connection details and a brief description.     

 

Part 6 (10%) Design Demonstration and Verification:  On March 30, 2012 all design projects should be demonstrated and verified to external reviewers and any interested individuals during the scheduled lab session in room En2021/En1038B. You will need to demonstrate the system functionality according to the specifications of your designed product as presented in the product brochure submitted a week earlier. You will be awarded 10 marks for a prefect demonstration and verification of your designed products (project and emergency light system) according to the specifications presented in the product brochure.   

 

Part 7 (8%) Project Final Design Report: On or before April 5, 2012 submit a detailed final project design report in pdf format on the course website. Report should have a title, names, an introduction, a system block diagram, description, system design including the mechanical and package details, complete circuit design, system photos, a software flowchart and a copy of PIC/PC code, an image of GUI, operating instructions, conclusions and some suggestions for the next version of a similar product design.  

 

 

Academic Integrity: Students are expected to conduct themselves in all aspects of the course at the highest level of academic integrity. Any work for which the student is claiming credit should be original work and the source of any submitted material that is not original must be given proper credit. Any student found to commit academic misconduct would be dealt with according to the Faculty and University practices.
