Direct Drive Solar Panel Control Circuit, Marcorios Bekheit May 2021

Direct Drive Solar Panel Control Circuit, Marcorios Bekheit

Physics

A control circuit is built for insulated solar electric cookers (ISEC). Power delivery and temperature safety are the focus. Using a maximum power point tracking (MPPT) algorithm, Arduino Nano, voltage and current sensors, and a buck converter, the solar panel’s output power was maximized for a direct load heat resistor with 3.5Ω for a range of solar intensities. Using a resistance temperature detector, a temperature sensor is built for safety shutoff.

Microcontroller Differential Gps To Subtract Signal Delay Due To Ambient Free Electrons In The Ionosphere, Diana Jane Swanson Jun 2019

Microcontroller Differential Gps To Subtract Signal Delay Due To Ambient Free Electrons In The Ionosphere, Diana Jane Swanson

Physics

The goal of this project is to create a Global Positioning System (GPS) receiver that is more precise than one GPS receiver on its own. The technique is to take the difference between a GPS receiver’s measured position and its actual position, then use radio frequency (RF) communication to send that differential value to another microcontroller GPS receiver. This differential value will be added to the measured second location to get a more accurate position for the second GPS receiver, thus creating a differential GPS.

Rfid Microscope Lab, Patricia Carranza Sep 2015

Rfid Microscope Lab, Patricia Carranza

Computer Engineering

The RFID Microscope Lab is a new exhibit created for the San Luis Obispo Children's Museum. The goal of the project is to create a modern, interactive exhibit that will teach children about different natural specimens through the use of technology. A computer, custom software, and RFID technology, will be used to display facts, microscopic images, and short videos of ten different specimens.

Spirit: A Home Automation System, Andrew Choi Jun 2014

Spirit: A Home Automation System, Andrew Choi

Computer Engineering

Spirit is a multi device home automation system. Designed and implemented for California Polytechnic State University’s Senior Project program, this project was worked on during the duration of two school quarters from January 7, 2014 to June 13, 2014. The system consists of monitor/controllers designed to carry out everyday tasks in the average American household and an accompanying mobile application designed to receive information and control the devices. The monitor/controllers, or “Spirits”, are primarily developed using Arduino development tools and Arduino microcontroller boards. The spirits include a thermostat, named Tempus, an electrical outlet, Electrus, and a wall light switch, Luxos.

Conception, Design And Construction Of A Remote Wifi Vehicle Using Arduino, Clayton Broman Mar 2014

Conception, Design And Construction Of A Remote Wifi Vehicle Using Arduino, Clayton Broman

Physics

The scope of this senior project was to make a wireless vehicle controlled via Internet Protocol. This vehicle operates remotely and without direct line of sight. Commands are sent from a program running on a laptop and transmitted using a wireless router. Visual data is retrieved from a network camera, mounted on the vehicle, in real-time, to see where you are going.

Viscosity Dependence Of Faraday Wave Formation Thresholds, Lisa Michelle Slaughter Dec 2013

Viscosity Dependence Of Faraday Wave Formation Thresholds, Lisa Michelle Slaughter

Physics

This experiment uses an electromagnetic shaker to produce standing wave patterns on the surface of a vertically oscillating sample of silicon liquid. These surface waves, known as Faraday waves, form shapes such as squares, lines, and hexagons. They are known to be dependent upon the frequency and amplitude of the forcing as well as on the viscosity and depth of the liquid in the dish. At a depth of 4mm and for various silicon liquids having kinematic viscosities of 10, 20, and 38 cSt, we determined the acceleration at which patterns form for frequencies between 10 and 60 Hz. For …

An Investigation Into Dual-Axis Solar Tracking, Daniel Spaizman Mar 2013

An Investigation Into Dual-Axis Solar Tracking, Daniel Spaizman

Physics

This senior project aims to determine a) if using a controlled photon-tracking system does produce greater voltage output than a fixed panel and b) by how much, if so. To do this, I built a dual-axis solar tracker using a small solar panel, some stepper motors, and an Arduino Uno. The majority of my time was spent familiarizing myself with the electrical components and fabricating the device. To test the performance of the panel, the leads of the solar panel were attached to the Arduino to record the output voltages. Two experiments were carried out to discover the answers to …

Teaching Introductory Programming Concepts: A Comparison Of Scratch And Arduino, Anne Beug Jun 2012

Teaching Introductory Programming Concepts: A Comparison Of Scratch And Arduino, Anne Beug

Master's Theses

Computing has become an integral part of modern America. The Bureau of Labor Statistics estimates that between 2008 and 2018, the United States will have 1.4 million job openings in computing fields [1]. Since the early 2000's (just after the "dot com bust"), the number of students enrolled in computing majors (Computer Science, Computer Engineering, etc.) dropped precipitously by over 50%, only starting to rise again in 2009 [2]. One way to rectify to this gap between demand and supply is to start training students in computational thinking during high school. While the Computer Science Advanced Placement AB test has …
