Electrical Engineering (2nd)

These projects are at the endpoint of a two-semester sequence. They are functionally complete.

Dual-Use Wideband Microphone Array System

E2.01 Logo

Sponsor: NASA TSGC

Student Team: Hannah Louviere, Billy Flores, Jesus Hernandez, Daniel Lewis, Micah Snell, Anthony Woods 

Faculty Advisor: Dr. Richard Compeau 

Our project is a Dual-Use Wideband Microphone Array System using MEMs microphones to detect both voice and ultrasonic frequencies. The project produces a proof of concept system that monitors the condition of the spacecraft and pressurized volumes by examining the room for anomalous ultrasonic signatures (e.g. gas leaks) and alerts the severity of the problem by sonification, an audible sound, to the NASA crew. The system simultaneously provides an audio communication channel that has the ability to localize and track a speaker in a room for the crew members to talk with one another while achieving high efficiency in detecting hazards on board.

Using 4NEC2 for HF Antenna Design

E2.02 Logo

Sponsor: Texas State University, Dr. Rich Compeau 

Student Team: Roberto Colon, Jorge Blanco, Dennis Liao, and Drew Schmidt 

Faculty Advisor: Dr. Karl Stephan 

This Project involves the design, simulation, construction, and verification of an HF antenna that is capable of receiving narrow bandwidths of multiple frequencies on the HF band. The project uses open source software for design and simulation along with Software defined radio for reception and a vector network analyzer for characterization and comparison of results. 

Drifter Blue

E2.03 Logo

Sponsor: Laura Phoebus

Student Team: Jeremias Celidon-Garcia, Julio Navarro, Eric Mercado, Mandi Renae Palencia 

Faculty Advisor: Mr. Lee Hinkle 

Drifter Blue has added two communication devices to access water quality data through short distances and remote access. Our short range access is ideal for a low-cost build that high school students can replicate and implement in their communities. Additionally, our long range access is used to obtain data for long periods of time to help Jacobs/NASA track localized climate change.

Heat Island Mapping

E2.04 Logo

Sponsor: Mr. Lee Hinkle 

Student Team: Rami Qadder, Jaylen Gilkey, Hunter Russo 

Faculty Advisor: Mr. Lee Hinkle 

This device is a handheld data logger that will collect temperature and GPS data. This data will be transformed into a Heat Map, which can be used to identify Urban Heat Islands. Urban Heat Islands are urban areas with high temperatures due to poorly planned city infrastructure. City Planners can use heat maps to locate possible heat islands, and take steps to change their infrastructure to lower these temperatures. Heat island warming is responsible for 50% of the global warming seen by climate change


Heat Island Mapping

E2.05 Logo

Sponsor: Texas State University 

Student Team: Jose Silva, Andrew Flores, Cameron Muir, Gabriel Montero-Sierra 

Faculty Advisor: Dr. Semih Aslan 

This device will record temperature and humidity and store the data on a local and cloud storage. Along with a touchscreen display to show last recorded data to the user, a web application will be made for visualization of the recorded data to the user. The handheld device will have a minimum battery life of 4 hours and be able to store at least one month's worth of data. 

ASR Heat Island Mapping

E2.06 Logo

Sponsor: Lee Hinkle, Texas State University 

Student Team: Samuel Garcia, Robert Schneider, and Amy Akers

Faculty Advisor: Dr. Semih Aslan 

Our device will collect and record temperature and humidity data along with the time, date, and location at which the data was collected. While in use, the immediate time and temperature data will be displayed on the device's LCD screen along with a battery indicator. All of the data will be stored locally and transmitted to cloud storage. Once the data is stored it will be used to dynamically create an integrated virtual map detailing the temperature changes along a traveled route.  

Project P.L.A.N.T.

E2.07 Logo

Sponsor: Mr. Mark Welker 

Student Team: Joel Martinez, Noah Campos, Cody Carlson, Austin Hunt-schley 

Faculty Advisor: Mr. Mark Welker 

Our project is a highly autonomous hydroponic system designed for outdoor use. The system monitors the general health of the plants and tends to them on a day-to-day basis. The system reduces much of the hassle of taking care of plants and provides a greener alternative to traditional growing. 

Smart Leaf

E2.08 Logo

Sponsor: Mr. Mark Welker 

Student Team: Josh Meyer, Joseph Wylie, Brogan McGraw, Dereck Ngo 

Faculty Sponsor: Dr. Harold Stern 

The Smart Leaf, our automated hydroponics system, provides a convenient method of gardening indoors with limited space. With the Smart Leaf, anyone can plant seeds of their choice and be sure that it will be healthy and thriving with minimal maintenance. Our system will be able to detect key information such as pH, temperature and water level and alert the user if any values fall out of the ideal range, provide automated lighting and watering of the plants, and also collect and store the system’s performance data. The data collected will be parsed and uploaded to the cloud where the user can view tables and graphs regarding the system’s performance over time. 

GAIA Smart Garden Controller

E2.09 Logo

Sponsor: Mark Welker

Student Team: Patrick Schneider, Brandon Sanders, and Jordan Bonn 

Faculty Advisor: Dr. Maggie Chen

GAIA is a smart garden controller that allows the user to automate a plants' growing cycle. This system continuously monitors the ambient and water environments by recording data on variables such as pH, water temperature, ambient temperature, humidity and the light levels. The collected data can be viewed locally on the systems touchscreen or remotely using our accompanying Mobile Application. GAIA also allows the user to create schedules via relays, to simulated day and night modes using a 0 – 10 Volt lighting control scheme and external devices. 

Automated Hydroponic System

E2.10 Logo

Sponsor: Texas State University 

Student Team: Anthony Meza, Kyle Pennington, Thomas Paveglio  

Faculty Advisor: Mr. Mark Welker 

We are building a hydroponic system automated with microprocessors that are capable of self regulating plant nutrition and supplemental lighting. The design will keep plants alive for seven months while allowing the grower to remotely monitor process information and process status. 

Full Home Automation

E2.11 Logo

Sponsor: Mr. Jeffrey Stevens

Student Team: Anthony Pummill (PM), Leondre Washington, Javier Benitez Albiter, Damien Pena 

Faculty Advisor: Mr. Mark Welker 

This project showcases Home automation and IoT utilizing Home Assistant OS. Our team is building a scalable system that will control and/or monitor devices commonly found in the home such as lighting, entertainment, security, and local environmental sensors. Each subsystem will have a variety of controlling mechanisms including voice, emulated, and scheduled events. With monitoring and automation the systems designed in this project help to increase energy efficiency and security of the home while providing more convenience by scheduling and voice controls.
