Special Circuit :: ECE 445 - Senior Design Laboratory

Special Circuit

A student whose Senior Thesis Project (ECE 499) does not involve the design and construction or testing of electronic devices or hardware is required to complete a Special Circuit Project in the ECE 445 lab during the semester they take ECE 499. In addition, students enrolled in ECE 445 who are not undertaking a hardware dominant project are required to complete the special circuit (although this is strongly discouraged and the course staff will work with your team to make sure you have enough hardware in your project to avoid having to complete the special circuit.)

The special circuit is typically posted in the middle of the semester. Once you sign up for the special circuit (see below), you will be assigned a TA, a locker, and a special circuit which generally takes about 12-15 hours to complete. When you have it designed and built, you will give a functional demonstration to your TA, who will then inform the professor who will inform undergraduate advising that your task is complete. You are NOT required to attend any of the classes, reviews, demos, or presentations associate with the ECE 445 class.

Sign up for Spring 2020 is now open

Sign up for the Special Circuit assignment on the Lab Access page. Instructions for completing the special circuit will then be provided in the near future. Please check this page for updates.

Problem

Drum majors lead and conduct marching bands. One of their main jobs is to maintain tempo for the musicians by moving their hands in specific patterns. However, many drum majors, especially high school students, need to learn how to conduct specific tempos off the top of their head and maintain a consistent tempo without assistance for performances. Even those with musical experience have difficulty knowing for certain what tempo they're conducting without a metronome.

Solution Overview

Our project consists of an arm attachment that aids drum major conducting. The attachment contains an accelerometer that helps determine the tempo in beats per minute via hand movement. A display shows the beats per minute, which allows the drum major to adjust their speed as necessary in real time. The microcontroller data is wirelessly transmitted, and a program can be downloaded that not only visualizes the data in real-time, but provides an option to save recorded data for later. There is also a convenient charging port for the device.

This project is a unique invention that aims to help marching bands. There have been previous projects and inventions that have also digitized the conducting experience, such as the Digital Conducting Baton from Spring 2015. However, these have been in the form of a baton rather than a glove, and are used to alter music files as opposed to providing feedback. Additionally, orchestra conductors use very delicate motions with a baton, while drum majors create large, sharper motions with their arms; thus, we believed that an arm attachment was better suited for marching band usage. Unlike other applications that only integrate digital instruments, this project seeks to assist live performers.
