The senior engineering design project presented in the paper that succeeds this, outlines the steps taken to design and implement an electronic bicycle that is able to keep a user’s heart-rate in a selected “intensity zone” though the use of an electronic motor and custom control circuitry. My portion of this project was to allow for safe and consistent power delivery to the rest of the electronics. That is to say, I built a battery pack and battery management system (BMS) to safely supply sufficient power to the rest of the electronics that were required for this project. In order …

The goal of this project is to create a high-quality, power-efficient audio amplifier. Most modern audio amplifiers use a constant amount of power regardless of the signal that is being amplified. This means that both loud and quiet portions of the audio signal require the same amount of power to amplify. The idea for this high-quality, power-efficient audio amplifier is that the quieter portions of the audio signal can be amplified using less power. This will be achieved by first analyzing the audio signal and controlling the power source based on the signal’s needs. Therefore, louder parts of the audio …
