Course Overview

Welcome to ECE 445! If you've looked at the course Calendar, you've probably already noticed that this class is quite different from most other classes in the department. The class only meets as a whole for the first few weeks of the semester. During these lectures you will meet the Course Staff, learn about specific assignments, requirements, and resources for the course, and have a chance to meet other students to share ideas and form teams. These are some of the most important weeks for the class since the decisions you make during this time will determine what you'll get out of this class and, in many ways, how much you'll enjoy it.

Outside of lecture, you are expected to be working on your own to develop ideas and form teams. You are also expected to actively participate on the Piazza discussion board to exchange ideas, receive feedback from course staff, and eventually get your project idea approved. Once your team has a project approved, you will be assigned a TA, with whom you will have weekly meetings. Think of your TA as a project manager. Keep in mind that they are not there to do the work for you. Rather, they are there to keep you on track, point you towards resources (both within and outside of the department), and evaluate the result of your efforts.

Expectations and Requirements

We have high expectations for students participating in ECE 445. You are soon to be alumni of one of the top ECE departments of the world. Our alumni hold themselves to high technical and professional standards of conduct. In general, projects are expected to be safe, ethical, and have a level of design complexity commensurate with the rigor of the ECE Illinois curriculum. Requirements for specific assignments due throughout the semester can be found by looking through the Grading Scheme for the course. Please read through this documentation well before each assignment is due. Specific due dates can be found on the course Calendar.

Below are a few words of wisdom to keep in mind throughout the semester to increase your enjoyment and success in the course:

Title: BarPro

Problem: Many beginner weightlifters struggle with keeping the barbell level during lifts. Even seasoned weightlifters find their barbells swaying to one side sometimes. During heavy lifts, many people also struggle with full movements after a few repetitions.

Solution Overview: BarPro is a device that straps on to a barbell and aids the lifter with keeping the barbell level, maintaining full repetitions and keeping track of reps/sets. It keeps track of the level of the barbell and notifies the lifter with a sound to correct the barbell positioning when not level. The lifter can use the device to calibrate their full movement of the repetition before adding weight so that when heavy weight is applied, the device will use data from the initial repetition to notify the lifter with a sound if they are not lifting or lowering the barbell all the way during their lift. There will be an LCD screen or LEDs showing the lifter the amount of repetitions/sets that they have completed.

Solution Components:

Subsystem #1 - Level Sensor: An accelerometer will be used to measure the level of the barbell. If an unlevel position is measured, a speaker will beep and notify the lifter.

Subsystem #2 - Full Repetition Sensor: An ultrasonic or infrared distance sensor will be used to measure the height of the barbell from the ground/body during repetitions. The sensor will first be calibrated by the lifter during a repetition with no weight, and then that calibration will be used to check if the lifter is having their barbell reach the calibrated maximum and minimum heights.

Subsystem #3 - LED/LCD Rep/Sets Indicator: LEDs or a LCD screen will be used to display the reps/sets from the data measured by the accelerometer.

Criterion for Success: Our device needs to be user friendly and easily attachable to the barbell. It needs to notify the lifter with sounds and LEDs/LCD display when their barbell is not level, when their movements are not fully complete, and the amount of reps/sets they have completed. The device needs to work smoothly, and testing/calibrating will need to be performed to determine the minimum/maximum values for level and movement positioning.
