ANCHOR is a modular retrofit kit for commercially available RC boats. The kit preserves the stock motor and rudder but replaces the control electronics to enable long-range telemetry and GPS-based tracking. A Raspberry Pi Pico microcontroller processes onboard control, and communication is done via a LoRa link. User input is controlled by a GUI on shore, which controls the motor and rudder systems, and various sensors on board.

BubbleMachine is a web-based tool created for people in the music industry that works with audio in a clear and intuitive way. Users can load audio stored on their device or extract audio from video files, then create precise playback markers called “bubbles” to add comments and feedback. The project focuses on improving tablet usability, touch interaction, and performance, while keeping all media local to the user’s device for privacy and copyright safety.

The purpose of the project is to develop a Motor Generator Inverter Controller that tests the characteristics of an AC machine under various operating conditions. The system inputs a 1ϕ 120V AC outlet power into a PowerFlex 525 Variable Frequency Drive (VFD) that outputs 3ϕ 208V AC into the motor. The motor drives the generator through a shaft and the generator produces 3ϕ 208V AC power. The 3ϕ 208V is supplied into a second PowerFlex 525 VFD that also outputs 3ϕ AC Power. This creates a full motor/generator inverter system used to study speed control and voltage.

This is a project sponsored by the General Atomics Electromagnetics Group. The project involves the design, prototype build and test of a ligh- weight thermal control valve - known as a valve mixer. A valve mixer is a mechanical device that controls fluid temperature by blending fluids of different temperatures to provide consistent and precise fluid temperature and control.

The goal of this project is to create a repeatable and scalable methodology to build a novel hydrographical geospatial database of waterbodies viable for water co-located solar (AquaPV). The project involves identifying waterbodies, creating highly accurate polygons of them, assigning a multitude of metadata to each polygon, determining the feasible buildable area of each waterbody, and determining the proximity to major infrastructure like transmission lines to assess economic feasibility.

This report outlines the conception, design, development, and testing for the DC-to-AC 3 phase Inverter project under the sponsorship of SDSU professor Tong Huang. The primary objective is to develop hardware-usable Pulse Width Modulation (PWM)-control-algorithms for a grid-tied inverter. These standardized control algorithms will aid Professor Tong Huang with his research on grid security in the Texas electricity market (ERCOT).

The robotic palm trimmer end effector replaces manual palm trunk trimming to improve safety and ease. It features an improved circumferential track system and a radial positioning stage that has a 360° reach around the trunk to cut fronds. The trimmer integrates with the Robotic Palm Elevator that operates through a shared controller and power source. The elevator moves vertically via a joystick control while maintaining constant arm tension as it performs the cutting process.

Our senior design team implemented a fully tapeout-ready AES-256 CBC encryption/decryption core, completing the full RTL-to-GDSII ASIC design flow including synthesis, place-and-route, DRC/LVS verification, and post-layout simulation. In parallel, we developed an FPGA-based prototype on a custom PCB with a UART-to-USB interface, enabling secure communication with a laptop through a custom GUI and driver software. The system demonstrates practical hardware cryptography and secure hardware integration inspired by Trusted Platform Module (TPM) architectures.

Masimo designs instruments, sensors, and cables that terminate connections in a variety of multi-contact connectors. When connectors are repeatedly cycled through insertions and removals, they wear the plating on the contacts and/or the pins and sockets themselves. Our device is capable of continuously monitoring a multi-contact connector for a change in contact resistance over the duration of connector insertion/removal cycles.

This project focuses on key plasma diagnostic systems for General Atomics’ DIII-D SupRISE Test Stand, which utilizes an RF-inductively generated ion source to replace the current arc-filament system on the tokamak. The Plasma Eater diagnostic system and Faraday shield developed as part of this project are intended to enable the SupRISE Test Stand to operate at higher power levels while providing more accurate and reliable data acquisition of desired plasma parameters.

The robotic gaming partner includes an AI powered 6-DOF arm driven by the NVIDIA Jetson Nano. The robot uses camera vision to play a 2 dimensional game on a whiteboard against a human user. When a user approaches the system, a touchscreen display greets them and allows them to choose which game to play against the robot. An ultrasonic sensor scans the 'warning' and 'play' zone to allow for operation of the system. A custom ADC was developed to convert the analog output of the sensor into the GPIO pins of the Jetson Nano.

This project's goal is to design and construct a single flow-cell test chamber for testing multiple gas sensors simultaneously. The chamber accomodates an array of gas sensors. A data acquisition (DAQ) system is incorporated to collect the electrical output from each sensor channel and transmit the measurements to a computer interface, where the real-time data is displayed on a screen for monitoring and recording.

The Automated Synchro Tester is a joint Mechanical Engineering and Electrical & Computer Engineering project sponsored by General Dynamics. The tabletop system autonomously rotates a synchro to specified mechanical angles while measuring the corresponding electrical angle to calculate angular error. Programmed in LabWindows, it reduces test cycle time and operator ergonomic risk. The system integrates precision actuation, sensing, and data acquisition to improve production efficiency, measurement reliability, repeatability, and reproducibility.
