This project will involve the design, construction, and testing of a prosthetic leg for a dog that is missing one leg.
Decentralized Filtration System
In this project, a manual-mechanically powered filter will be designed to take in unpotable freshwater and pump out potable water. Filtering is done by a Nano-filtration membrane element and the needed water pressure is applied by a piston-lever system.
Exploring Passive Sound Reduction Techniques For UAVs
Travis Lemke and Dallas Probert
During the course of this project, we will explore multiple techniques to passively reduce the noise produced by the propellers on a UAV, specifically, a quadcopter. These techniques include reducing tip speed by experimenting with different props and absorbing sound waves using sound absorbing materials around the blades. A big piece of this project will be modeling and 3D printing an induction ring with the aim of absorbing sound while increasing efficiency. Using sound detection equipment, we will find the most efficient ways to reduce noise and implement multiple techniques at once on a UAV to maximize total noise reduction.
VIPIR Soldering Tool
VIPIR is a satellite servicing tool that will hold a variety of attachments that will enable it to fix or upkeep satellites orbiting earth. For my project I plan to build a robotic arm attachment and modify it so that it can solder a broken circuit, a possible issue that a satellite may experience.
Coffee – Physics and Roasting
Physics and engineering is the basis for the entire process of coffee. In this experiment, I looked at the physical changes involved during the roasting of the coffee and the effect that it has on flavor and acidity.
Investigating Projectile Motion
In this project, a set up for projectile motion will be constructed involving springs and magnets. The extra forces and velocity that give rise to projectile motion will be investigated.
The Impact of Ball Weight on the Game of Baseball
This is a study of how differing weights of baseballs with identical diameters could influence the velocity of pitches and batted balls and the distance of ball flight. The data was collected over 2 years by pitchers on the Point Loma Nazarene University baseball team.
Camera Memory: How Does It Work?
I have always wondered how cameras are able to store pictures and videos as memory. Some cameras have memory cards that have to be connected to the cameras themselves. The purpose of my project is to find out how the camera I am looking at is able to store data into its memory card.
Measuring the Resistivity of Fiber-Reinforced Plastic for the Deep Underground Neutrino
In this project, the resistivity of fiber-reinforced plastic (FPR) was tested using very high voltage (~-3000 V) to see if the material could withstand the extreme environment (-180,000 V in liquid argon around 87 K or -186 C). My experiment was done at close to constant temperature (though I did get to dip the material in liquid nitrogen and then hit it with a mallet to see if it would break - it didn't). The data will be graphed to show the resistivity curve of the material.
Immersive Manifold Hydr-O Tapping Electricity Producer (or IMHOTEP, for short)
I believe God, our creator, is the ultimate architect. And, in his design of nature comes many ideas in which we borrow from. The power that water has when falling can literally move mountains. So, I have decided to call this device I.M.H.O.T.E.P. after the name of the famous architect of the Egyptians. His name means “the one who comes in peace”. And, since Imhotep was one of the only Egyptian commoners to receive divine status after death, I thought it fitting to name this structure after a god architect. This device can connect to a hose or pipe that would normally have water running through it. The device would get spun which would turn an arm that have a magnets on the end of it. The magnets would also be in the presence of copper coils that are connected to a circuit. The running water would cause a current to be formed so that you can harvest the electricity for re-usable energy to your liking.
2015–16 Senior Projects
Exploration of Robotic Motion
A mobile robot was designed and constructed using the MSP430G2 LaunchPad. The final design bounced on springs and responded to sound and light inputs.
An Exploration of the Product Research and Design Process: Mini-Inflatable Tube Man
The focus of this project was to research and understand the process of product design more fully from initial conception to marketing. The patent process was explored, the actual designing and testing of the product was done, and planning of how to market and effectively sell the product was undertaken.
Comparison of Raspberry Pi and Arduino in a Light-Show Application
The purpose of this project was to create a system that can take a music input and turn it into a visualization using LED lights and microcontrollers. During the project, research was conducted to determine which microcontroller runs the fastest and is the most eﬀective in the three main components of the build: audio analyses, LED control, and servo control.
