Generalized Featured Product Page, Andrew J. Pirondini
Generalized Featured Product Page, Andrew J. Pirondini
Computer Science and Software Engineering
The goal of my senior project was to generalize the process of creating featured product pages with iFixit. Featured product pages are pages with custom content describing an individual product such as text blurbs, images, and even some responsive components. These do not have a simple template like products you might see on Amazon but instead involve scrolling through a variable amount of content.
In order to generalize these, each part of the page was broken into discrete components that contain custom content. There are components for images, paragraph blurbs, lists, footers and more. These components are implemented with React …

Imagine you are a property manager, and you are currently renting your property to tenants. These tenants, who pay rent continuously for use of the property often leave the burden of upkeep to the property owner (or property manager). If the tenant were to run into an issue with their rental (such as a broken sink, replacement of a faucet, leaking of the roof, … etc.) they would have to coordinate with the property manager, who would then in turn have to manage the logistics of a service contractor and the tenants availability. Eventually, after logistic juggling from the tenant, …

Baseball Shagger, Anthony Velasquez, Nick Walker, Nathaniel Kai Paresa
Computer Engineering
The purpose of our project is to allow players to hit baseballs on a baseball field and not have to worry about picking them up. By combining our knowledge of software and hardware, we developed the first design of a robot that “shags” baseballs. Our endeavor was only partially successful. The device was tested on grass, turf, and concrete. The motors did not have enough torque to get moving on grass. The device faired better on turf where it could move, but was quite jerky as the motor drive needed to be high to start moving, but once it was …

Modular Injection System And Sampling Template (M.I.S.S.T) Design Report, Froylan M. Aguirre
Computer Engineering
Digital systems are ubiquitous throughout modern life and their applications continue to grow. Thus system designers engineer and test modular systems to mitigate error rates. Smaller systems and their increasing importance in many applications demand the utmost reliability. Fault injection is the most common method used by researchers and engineers to test system reliability. However, most hardware fault injection implementations are ad hoc and only used to test a specific system or for specific tests. There is also software-implemented fault injection that adds overhead in the benchmark source code. The aim of this project is to develop a general use, …
Bicycle Power Meter, Andrew Mcguan
Bicycle Power Meter, Andrew Mcguan
Computer Engineering
A power meter is a cycling training tool used to record the power a rider is outputting. This is very useful to athletes who regularly do bike workouts, because the power output is a consistent measure of the rider’s effort level, and is not affected by outside factors such as wind or road gradient. If a cyclist does a workout with the intent to carry a certain speed for a certain amount of time, a strong headwind will slow them down and make them work harder to maintain the same speed, defeating the goal of the workout. When a power …

Computer Engineering
After Cal Poly Racing’s electrical team began to hit the technical limits of the ADC and other I/O features of the current 8-bit Atmel AT90 microcontroller unit, it became clear that an upgrade was due. This replatforming project takes the functionalities of the old, 8-bit architecture, and aims to provide a 32-bit version using the ARM MKE1xF MCU. With the idea of having a working PCB as a stretch goal, the scope of the library development was limited to enable base functionality. Thus, the only libraries developed were for the Timer, ADC, SPI, UART, and CAN. Additionally, this document discusses …

Analog Sorting Using Pulse Width Modulation, Riley C. Olson
Computer Engineering
As time goes on, computers become more and more powerful. However, as processing time becomes less of a limiting factor for computing tasks, power consumption takes its place for many tasks. This paper proposes and tests a new method for sorting analog signals. This new sorting method converts analog signals into Pulse Width Modulated(PWM) signals of varying duty cycle , which are then sorted by a simple network of combinational logic, and then converted to a normal binary representation. In order to implement this new method, multiple circuits had to be designed and and tested to ensure their functionality and …

Tracking Eye Movements Over Source Code, Faith Chan
Tracking Eye Movements Over Source Code, Faith Chan
Computer Engineering
Studies on software developers’ behavior guide the development of tools that facilitate source code reading and reviewing. Eye trackers have allowed researchers to study this behavior in more detail–to pinpoint where the developer is looking, or even to detect which source code element the developer is viewing. However, systems that map gaze to characteristics as specific as source code elements are often expensive, either because of the cost of compatible eye trackers or because of the cost of the required software. This project aims to use existing technology to create a lower-cost system that provides information on the source code …
