Smart USB-C Wall Plug for the DC House Project
Get PDFDC operated devices and appliances powered by AC systems suffer inefficiencies resulting from the losses of converting AC energy into DC energy. At Cal Poly, the DC House Project aims to minimize the need for AC electricity in homes and encourage the use of renewable energy systems. The DC House uses a 48V DC bus that must be stepped down for use with increasing number of DC loads in a typical home. In this project, a Smart USB-C Wall Plug is designed to work with USB Power Delivery to provide a variable voltage output for use with these DC loads that operate at 5V, 9V, 15V, and 20V up to 3A. The Smart USB-C Wall Plug was implemented in hardware using a custom PCB and tested to show that it met requirements for 1% line regulation, 1% load regulation, 5% voltage ripple, 90% efficiency, and 60W maximum power. Further measurements demonstrated that the output voltages except for 5V met the 1% line regulation and 5% voltage ripple requirements
Ris Magazine Brand Book, Website Redesign, and Social Media Expansion
Get PDFRisograph printing is not often discussed when it comes to the print world. What is it? How can creatives utilize it to its fullest potential? There is an opportunity of informing more about Risograph printing through the redesign of Ris Magazine—a fictitious online magazine. Ris Magazine teaches Risograph printing practices as well as features artists, stores, and creatives in the Riso world.
For this project, my goal was to create a branding style guide, a functional website, and an Instagram feed promoting stories from the website
A Composer\u27s Guide to the Clarinet
No full textThis paper, A Composer\u27s Guide to the Clarinet, is intended to help composers and orchestrators of any level of composing experience. Through this guide, a composer can begin to understand the clarinet\u27s capabilities and limits. It is not meant to be a comprehensive guide, but rather a source that gives a composer a better understanding of the clarinet as an instrument in general. This includes the basics of the instrument, how the instrument fits into ensembles, its history, and the different types of clarinets. While this guide focuses on the B-flat clarinet, the most common clarinet, the information discussed in this paper can often be applied to the other types of clarinets
Mother Lou Studio: Branding for a Handcrafted Jewelry Business
Get PDFIn the height of the pandemic I gained interest in jewelry-making. Needing a new hobby, I researched the many methods of making jewelry and soon began practicing the craft. Sand casting became a form of meditation, and I hope to gain more experience in silver smithing in the near future. For my senior project, I wanted to combine my personal, creative abilities with the skills I have learned through my Graphic Communication courses. This project showcases my design and business skills, while building a unique brand that will be a part of my future career
Air Wear
Get PDFSince the outbreak of COVID-19 pandemic, hospitals have experienced an overwhelming increase in patients needing respiratory assistance. Our client identified the need for a sustainable, affordable, and portable outpatient device that will provide supplemental oxygen and assisted breathing to speed up the patient recovery process. Our team accomplished to design a device that contains a more sustainable oxygen supply method, has a longer functional duration, is safer and ergonomic, as well as compact
Designing Gmail on Apple Watch
Get PDFSmartwatches such as the Apple Watch and Samsung Watch have become a vital bridge between today’s fast-paced digital and physical world. According to a recent report done by the International Data Corporation, smartwatches grew 54.3% in 2018, signaling to developers that these devices aren’t going anywhere. Because of the smartwatch’s popularity, there is an opportunity to develop innovative solutions for apps on the Apple Watch. As a UX/UI concentration at Cal Poly, I have only designed interfaces for web and mobile devices, allowing me to have more space for additional functionality. I want to present myself with a new challenge by designing a smaller interface that only allows for limited features. I intend to apply the concepts and skills I have learned in the Graphic Communication program to develop efficient and usable solutions
SunSation’s Solar Powered Picnic Table
Get PDFTeam SunSation is an interdisciplinary senior design project group that was tasked with developing a semi-permanent seating area for Cal Poly\u27s electrical engineering courtyard. The EE courtyard is populated with plastic folding tables and chairs that are slowly falling apart. Dale Dolan, the head of the EE department, requested that a table design be developed that incorporates the use of solar panels. The addition of the solar panels to the table would help promote clean renewable energy as well as provide shade to those sitting in the courtyard.
The solution that SunSation arrived at is broken up into mechanical/structural, electrical, and software subsystems. The table is made up of a steel frame with concrete benches and tabletop. At the bottom of the table frame there are steel c-channels that allow the table to be moved with a pallet jack. The table utilizes a single-axis solar tracking system with two solar panels donated by the EE department. A 10 ft. steel tube column stands at the center of the table and supports the solar panels. The solar panels sit at 30° from the horizontal at the top of the column. A linear actuator is attached to the solar panels and center column of the table and is used to rotate the panels ± 30° from their neutral position.
In addition to solar tracking, the table also boasts features such as LED lighting, USB charging, and data collection. All these features are controlled by a Raspberry Pi that lives in the waterproof box that houses the table\u27s electronics. The table lights are operated using a button on the table and are set to turn off after one hour of use. The solar tracking works off a real-time clock in conjunction with a dataset on sunrise and sunset times each day at the product’s coordinate location. The table also includes a QR code that directs users to a website that shows data analytics from solar collection and consumption, as well as information on the project itself.
Manufacturing of the table was a substantial part of the project. The manufacturing process consisted of cutting and welding the table frame, mixing concrete, and assembling hardware for the solar tracking system. The team completed manufacturing and conducted testing on the table in the EE courtyard to ensure that all design engineering specifications were met. Some issues such as Wi-Fi connectivity, solar tracking software bugs, and motor controller hardware failure were discovered during this testing process. After resolving the discovered issues, the final assembly of the table was completed. The final product is now in the EE courtyard, and it has seen immediate use by students that study in the area
MMTEG Heatsink Design
Get PDFIn this document, Cal Poly Senior Design Team F16 presents a summary of its work developing a suitable heatsink for Gas Technology Institute’s Methane Mitigation Thermoelectric Generator. After several months of iterating between experimental testing and simulated heat transfer, a suitable prototype was selected for use in further refining simulation parameters. This was called the structural prototype and it allowed Team F16 to confirm several remaining unknowns relating to component thermal conductivity. All documentation of this process can be found in Preliminary, Critical, and Interim Design Review documents (PDR, CDR, IDR), included in this report. Having a realistic model of the system enabled further rounds of simulation to select a heat fin array. This array was then added to the already existing structural prototype along with testing hardware to produce a final verification prototype. It performed satisfactorily during the team’s experimental testing, per GTI’s identified criteria and benchmarks. Team F16 also received sponsor confirmation that these results meet all project requirements. A final design and key recommendations for moving forward into high volume manufacturing are compiled along with this report
