Projects
I have worked on various projects for classwork, research, or just for fun. Below are a few examples of my work.
Capstone Project - Wireless Digital Stethoscope & ECGFor my capstone project (year long final project for B.S. at BYU) I and a team of five other students designed and built a prototype for a completely digital and wireless stethoscope and ECG device.
Stethoscope data is taken from a microphone at the base of a standard stethoscope bell. ECG data is taken from both thumbs and an index finger. This data is then transmitted via Bluetooth to an iPhone which processes and displays the data visually. The audio data is simultaneously transmitted to a set of wireless headphones for live listening of the data. The iPhone app also saves audio and ECG data and allows it to be stored for later or use or emailed to either the patient or another doctor for a second opinion. My team and I were able to get all aspects of the device functioning properly and presented to the president of the industry company that sponsored the project (Curtis Mason from Sound the Bell LLC). |

Ping Pong Shooting Robot
For my Mechatronics class we designed and built a robot that would autonomously navigate to the center of a box in less than 15 seconds. Then an IR LED would light up in a random corner. The robot had to find the correct corner and shoot three ping pong balls into a 2"x2" target 15" off the floor of the box. This would continue until all four corners and been lit and targeted.
We chose to use a vertical pipe as our hopper for simplicity. We used two rotating tires to shoot the ball and an ultrasonic sensor to detect distance to the walls and navigate to the center. We were able to hit the target with reasonable accuracy as well as navigate to the center of the box using a novel algorithm we developed. The robot was controlled using a PIC24F micro controller. The entire robot was developed and assembled by our team of three students. Many of the parts were also designed and manufactured on campus (including the PCB for the main control circuit). |

RC Car Modeling International Experience
In my advanced CAD class we used Siemens NX to model all the components of an RC car. We also used analysis software to perform FEA on various parts of the car and then we used topology optimization to design a lighter and stronger version of the part. We also designed a car shell and performed CFD on it to find it's drag coefficient. We used motion analysis and photo-realistic rendering to create a final presentation that was judged by industry professionals from software companies such as Siemens, CD-Adapco, & Altair Engineering. Our team took 2nd place overall on our presentation.
My team consisted of myself, two other BYU students, and three engineering students in Mexico. We had to work together with our international teammates to build and perform analysis on our project. It was a challenging but rewarding experience and taught me a lot of international engineering design and work. |
