Automated microgreens growing appliance: designed to provide daily access to affordable microgreens. The project aims to provide the ideal growing environment for microgreens regardless of its surroundings. To achieve this our team developed an integrated controls system that oversees the watering, lighting, and climate of the growing environment through various electromechanical actuators, sensors, and custom PCB's. To ensure a consistent supply of microgreens to the user the device can grow up to five varieties.

Team Pharmhouse will design and manufacture a pill dispenser that will be able to distribute a desired amount of pills to their respective days in both weekly and monthly pill organizers, including am and pm weekly containers. The dispenser will also be able to be compatible with pills of a variety of shapes and sizes, as it is common for users to take multiple unique pills per day. The design will accommodate users with impairments such as arthritis, color-blindness, and various upper extremity issues.

The objective of this project is to design, fabricate and demonstrate a water bottle refilling station that elminates water spillage normally encountered with traditional stations. The station employs an infrared sensor to detect a bottle, along with a microphone that detects a predetermined rate of change in the cavity resonance frequencies providing key information on when the bottle is full.  Once the signal is detected indicating a full bottle, a microcontroller automatically shuts off the flow of water thus preventing overflow.

The ARES system is SDSU's submission to NASA's 2021 RASC-AL Moon to Mars Ice Prospecting Challenge with the goals of developing technologies capable of extracting water on the Moon and Mars and advancing the critical knowledge needed to further solar system exploration. ARES was designed as a prototype capable of extracting water from ice deposits buried beneath simulated lunar or Martian soil, identifying and mapping subsurface layers, and extracting water from a 600-pound ice block in a simulated off-world test bed.

DIGIMUSER is a digital vocal effect processor “stompbox” that applies a variety of real-time signal processing algorithms to alter the voice of a singer. DIGIMUSER uses a microcontroller and user controls to digitally apply vocal effects such as filters, delays, distortions, and modulations. DIGIMUSER takes a standard dynamic microphone as input and outputs to an amplifier or additional audio processing devices. To put it simply, DIGIMUSER gives anyone an entire effects studio right in the palm of their hand.

Motor Control is a challenge for many people taking on their first projects. Our team has designed a digital motor control that will allow a user to set the speed of a low voltage brushed DC motor and then the controller will maintain that speed even when the motor meets resistance. Think of it like cruise control for a small motor. Our team built this controller as an example for future students to follow when they decide to use motors in their own projects.

Helios gives smaller consumers the opportunity to use an energy management system that large corporations utilize. It maximizes consumer profits with peak shaving and plans ahead for future weather conditions. Power usage is monitored with CAISO and weather conditions are pulled from OpenWeather. Helios will be able to intelligently switch between using power stored in batteries or power from the grid depending on the algorithm.

Here’s to a greener future! See you there.

There is no vending machine on the market that automatically dispenses a custom granola mixture. This kiosk will allow the user to choose from a variety of granola bases and toppings through a user interface and have the ingredients mixed and delivered to them. Aztec Granola Factory is tasked with designing and manufacturing the architecture and all the major subsystems of the kiosk. This includes the 80/20 frame, ingredient storage containers, dispensing valves, and mixing/measurement mechanism.

Location tracking within a building is difficult with GPS or similar technologies; our team offers an indoor location-tracking solution through the use of Bluetooth Low Energy (BLE). Within a predefined grid, we make use of mobile and anchor nodes that send RSSI values that serve as the input to a machine learning algorithm, which predicts the location of the mobile node based on said RSSI values. A GUI is used to visualize the mobile node's location every 10 seconds, with the ability to replay past locations.

The MPPT will extract the maximum amount of power from a photovoltaic (PV) solar panel and provide the user with a constant voltage under various weather conditions. While tracking voltage and current from the input and output, the system will monitor ambient temperature and irradiance conditions and update the user via a TCP socket interface.

The current pandemic of COVID-19 has brought a halt to in-person instruction for both lectures and labs. As a consequence, students can no longer participate in hands-on labs, losing the real-world experience of having to set up and troubleshoot their lab equipment. My Desk Bench enhances both the experience of remote labs and a student’s learning by providing some missing functionalities or tools of in-person labs. It is intended to serve ECE students taking digital circuits and electronic labs.

This senior design project is tasked to design and build a Tier 4 approved, bio-fueled cook stove that incorporates Hi-Z’s thermoelectric technology to support two fans and electrical outlet. The cookstove is to be deployed to third world countries to families that use biomass as their main source of fuel. The purpose is to reduce emissions, improve efficiency and create a source of electricity in areas that have limited access to power. The system comes equipped with data logging technology to display temperature and CO.

The Tired Tracker device was created as a proof of concept  to the Transportation Security Administration (TSA) for a centralized system to allow users to view their fatigue level in real time by recording biometric data and transmitting it to an Android application over Bluetooth. The physical device consists of a small wearable embedded system strapped to the user’s wrist which collects body temperature, heart rate, and arm motion data in a non-intrusive way. An accompanying app analyzes the data and displays the user’s fatigue level on a scale of 1 (low) to 10 (high).

This system will allow the Transportation Security Administration (TSA) to measure wait times in screening queues.  It uses a Bluetooth Low Energy (BLE) system consisting of beacon devices and anchors. Beacon's are given to and carried by airline passengers when they enter the TSA security line. Each beacon will record the time it takes for a passenger to pass through the line. Once the beacon is returned to TSA, it will transmit time start, time end, and overall time elapsed to anchor devices with WiFi capability that will host the data for TSA to monitor average security waiting times.
