Current-Source Dc-Dc Converter, Rocio Sanchez-Mendoza, Carlos Aguilar, Adrian Aranjo
Electrical Engineering
In this project, a hardware implementation of a current-source DC-DC converter for powering sensors used in an underwater communications system is presented. The proposed converter is designed to step down an input current of 0.9 A to 0.625 A, while maintaining an output voltage of 24 V and output power of 15 W. An overview of the system design is explained as well as the component selection process. The design of the converter was simulated and evaluated using LTspice before being physically constructed on a printed circuit board. Performance evaluation of the proposed converter was carried out in multiple lab …

Wax Bee Gone: A Safe, Effective Solution To Ear Wax Removal, Robert G. Shenon, Shanvir S. Dhinsa
Electrical Engineering
This project sought to combine conventional methods such as scraping and water pressure to removal ear wax, but with electronic automation to removal the potential for human error as much as possible. Through the use of a 9V battery, and Arduino microcontroller, DC motors, and other circuitry, this project has developed a prototype for a device that can properly remove ear wax without any discomfort or risk to the user. Much of this project involved learning how to properly manipulate and provide the necessary power requirements DC motors from an Arduino and a 9V battery. Additionally, creating a 3D printed …

Merry-Go-Round Human Powered Generator, Sarah Lorraine Ashe, Salvador Navarro
Electrical Engineering
How do you bring electricity to families who have limited resources in a developing country? The DC House project, advised by Dr. Taufik, provides a way for kids to have fun, exercise and generate power for their homes – play-park human powered generators. This project intends to create a more efficient and cost effective way for playground equipment to be implemented for power generation. The redesigned and reconstructed merry-go-round human powered generator converts mechanical energy into electrical energy to power the DC house. This was a fully functioning generator that needed a better voltage gain, as well as, a more …
