Audio-Triggered El Wire Sequencer, Benjamin (Ben) Paik

Electrical Engineering

“Development of an Audio-Triggered EL Wire Sequencer” California Polytechnic State University 2011, Ben Paik and John Oliver, Ph.D. (advisor)

The purpose of this project is to investigate and develop a method for switching electroluminescent wire (EL wire) such that it can be activated by some audio source.  EL wire is essentially a coaxial capacitor that luminesces when an alternating electric field excites the insulating phosphor layer in the wire (a 100Vp, 1kHz AC source is sufficient for this).   The system involves the EL wire, a six channel sequencer to switch the EL wire, an method for processing the audio signal, …

Development Of Wind Tunnel For Laboratory Wind Turbine Testing, Danny Alexander Zepeda

Electrical Engineering

A wind tunnel with a 0.5 HP motor was purchased by Cal Poly Electrical Engineering Department from Hampden for $16,000. It can only simulate winds of up to 10 MPH. The tunnel has a manual dial that controls the wind speed. It also measures the voltage and current output with an analog measure display. This wind tunnel was expensive and unfortunately cannot achieve very high wind speeds. For this reason, a similar wind tunnel with more potential and with a smaller budget was proposed to be built for use in the Sustainable Energy Lab. The new wind tunnel that was …

Low-Power Self-Sustaining Schedule Display, Samuel (Sam) August

Electrical Engineering

The completed project is an Amazon Kindle, powered by a USB solar charger, running a student designed program to display a weekly schedule for a faculty member.  The purpose of the project was to design a sustainable electronic schedule display for use outside a faculty office.  It was designed in the hopes that faculty members could more easily update their schedules, and possibly allow for students to schedule appointments.  The program was designed using Java and the solar-charger was designed using a solar cell, Schottky diode, and a USB to micro-B USB cable.

Dyl-Light: An Acn Controlled, Rgbw Led Light Fixture, Dylan Pavelko

Electrical Engineering

The Dyl-Light is a LED lighting fixture that is controlled with a recently released suite of entertainment technology protocols called A.C.N. This new protocol has a number of advantages to its use over the existing protocol, DMX512, used for controlling entertainment lighting fixtures. This project attempts to use this new protocol to directly control a light fixture, something that currently is not available on the market.

The project includes several aspects of engineering from electronics, embedded systems, applications, networking, power electronics, and computer interfacing.

Discrete Alarm Clock, Travis Moore, Collin Barth

Electrical Engineering

The standard alarm clock, as used daily by millions worldwide, has clear room for modification and improvement.  This paper documents an implementation that rectifies many of these flaws.  Improvements include adjustable snooze length, an IR remote for ease of use, and an RF headset for discrete alarm use or potential incorporation into a device much like a hearing aid.  The processes involved in creating a digital alarm clock, as well as the obstacles met in the implementation of the enhanced design, are detailed within.

Wireless Sensor Network For Energy And Environmental Monitoring: Helping Old Buildings Go Green, Jacob Power

Electrical Engineering

Today, the rising cost of energy and social trend of “going green” has put increasing pressure on commercial property owners to improve the efficiency of their investments.  There is good reason for this, too.  In the State of California, office buildings represent the single largest user of energy in the commercial sector.  This project consisted of the design, implementation, construction, testing, and deployment of a wireless sensor network for energy and environmental monitoring in retrofit commercial office installations.  The analyzed data generated by this system can be used by building management and owners to identify areas of inefficiency within the …

Rfid Home And Office Automation System: Based On Localized Room Entry, Nolan Clark

Electrical Engineering

Design and build a proof of concept model demonstrating an application of Radio Frequency Identification (RFID) technology for use in a home or office lighting automation system. The system provides new means for reducing energy consumption through active light switching based on simplified location tracking. Often lighting systems use motion sensors and timers to determine when a person enters or leaves a room, but these platforms are based purely on motion meaning “no motion, no light.” The RFID based system utilizes medium range RFID readers and tags located at doorways or narrow passageways in the environment to provide a general …

Multiple-View Planetary Photogrammetry And Its Visualization, Kyle D. Husmann

Electrical Engineering

During the summer of 2010, Dr. Taemin Kim and Kyle Husmann jointly developed a novel new algorithm to generate topographical maps of planetary surfaces using a multiple-view photogrammetry approach. To evaluate and debug the algorithm, a program called mvpgui was developed to visualize and examine the objective function. After verifying the correct operation of the algorithm and mvpgui with synthetic data, it is run with real orbital data from the Apollo 15 mission. The results confirm the validity of the multiple-view algorithm as well as demonstrate the value of objective function visualization.

Global Positioning System, Vladimir Villalba

Electrical Engineering

The Global Positioning System (GPS) is a navigation network consisting of 24 satellites in orbit around the Earth. This satellite system provides the accurate position of an individual in all weather conditions at all times around the world. Individuals can use GPS receivers to locate where they are, pinpoint where they want to go with any form of transportation.

The senior project embarks in a path to understand the workings of the GPS satellite system. To accomplish this task, the concepts learned in Electrical Engineering will be implemented. This report encompasses the design process and steps taken in prototyping a …

Ofdm Simulation In Matlab, Paul Guanming Lin

Electrical Engineering

The objective of this project is to demonstrate the concept and feasibility of an OFDM system, and investigate how its performance is changed by varying some of its major parameters. This objective is met by developing a MATLAB program to simulate a basic OFDM system. From the process of this development, the mechanism of an OFDM system can be studied; and with a completed MATLAB program, the characteristics of an OFDM system can be explored.

Solar Panel Tracker, Andrew Hsing

Electrical Engineering

This project will be a design and implementation of a polar single axis solar panel tracker. It will have a fixed vertical axis and an adjustable horizontal motor controlled axis. This setup is similar to an office swivel chair. The tracker will actively track the sun and change its position accordingly to maximize the energy output. To prevent wasting power by running the motor continuously, the tracker will correct it's position after 2 to 3 degrees of misalignment. The sensors will compare the light intensities of each side and move the panels until the tracker detects equal light on both …

Sign Language Glove, Nicholas Born

Electrical Engineering

Between 500,000 and 2 million Americans use American Sign Language (ASL) as their primary language. As such, a device capable of translating those movements into text would be useful in many areas, such as teaching and the entertainment industry.

The goal of this project was to show that the creation of a glove device that takes in sign language letters, interprets them into the desired characters, and can input those characters into a computer is feasible. I chose to work on this project for many different reasons. One reason is many members of my family know sign language and use …

Automated Basketball Return System, Victor Mendoza, Chris Chamberlain

Electrical Engineering

The project is meant to assist a basketball player in their practicing. The project hangs directly on the basketball rim and automatically rotates to find the player on the court. Once the player is detected, the automated basketball return system (ABRS) stays focused in the direction of the player so that any baskets successfully made will be funneled back to the player. When the player moves from center, IR motion detectors find which direction you moved to and rotates accordingly, until the player is focused in front of the funnel again. If at any time the player is absent from …
