Through DSP, seven guitar effects can be applied to the input signal from the guitar to change the sound of the guitar to the user's choice. The interactive GUI of the pedal also allows for accessible switching between the different guitar effects and also adjusting the volume, mix, and other parameters of the effect over the guitar's sound.
Passive Analog Beamforming Drone Monitor
The FAA now requires all drones to be compliant with Remote ID, requiring an on-drone device that transmits information about itself over Blutetooth or WiFi. However, these signals can be weak and may not be picked up by user devices alone. Traditional methods of increasing reception range involve high cost and complex fully-coherent sampling digital beamformers. By leveraging a hybrid digital-analog beamforming strategy, this project achieves a similar result a remarkably lower cost, complexity, and footprint.
The goal of this project is to increase the reception range of 2.4GHz Bluetooth/WiFi signals by using an antenna array fed into a passive RF network allowing multiple different directional beams to be monitored at the same time using low cost microcontrollers. The collected data is sent over Bluetooth to a user device where the information is displayed on a custom React Native app.

A microcontroller gathering all the data from these sensors and aggregating the information and forwards it to a web application via bluetooth. The application communicates to a backend system through wireless communication which processes the sensor data and classifies the user's posture into interpretable categories such as slouched, straight, leaning left, leaning right, and arm positioning such as open or closed. The overall goal of the project is to promote better ergonomic habits by helping users become aware of posture issues and correct them through consistent monitoring and feedback.
Preventing Vial Waste Using a Multi-Modal Edge Computing System
This project addresses the need for fast and reliable defect detection in pharmaceutical manufacturing, where traditional inspection methods often rely on human oversight or cloud based processing that introduces latency and inconsistency. Defects such as micro cracks, improper sealing, or temperature anomalies in vials can compromise drug safety, leading to costly recalls and potential risks to patient health. By leveraging edge computing, the system performs real time, on device analysis that reduces latency while also lowering data transmission requirements and overall carbon footprint compared to cloud dependent approaches. This work directly impacts pharmaceutical manufacturers, quality assurance engineers, and ultimately patients who depend on safe and properly handled medications.
RepHlux: A Wireless, Batteryless Acid Reflux Monitor
The RepHlux project aims to develop an improved, minimally invasive medical device for diagnosing Gastroesophageal Reflux Disease (GERD), helping to prevent long-term health complications through more effective monitoring.
Current acid reflux monitoring methods rely on either battery-powered capsules or wired catheter systems. Battery-powered devices tend to be bulky and have limited operational lifetimes, while catheter-based systems can cause significant discomfort for patients. These limitations create a need for a more patient-friendly and reliable solution.
RepHlux addresses this gap via a belt-and-capsule transceiver system that uses radio frequency communication to transmit data between the capsule and an external belt reader. By eliminating the need for batteries and wires, the device enables real-time monitoring while improving patient comfort.
This project features an improvement in signal retention and upgraded specifications from previous works on a battery-less acid reflux monitor paper.
REX0: Dual Glove Stroke Therapy System
Stroke survivors frequently experience upper-limb impairment, with 55–75% losing fine motor control, and recovery often plateaus within six months, highlighting the need for accessible, high-repetition rehabilitation tools. Because proprioception—the body’s sense of limb position and movement—is commonly impaired after stroke, improving it is critical for restoring hand function. This project addresses that need by developing REX0, a dual-glove wearable rehabilitation system that enables motion mimicry, allowing movements from a patient’s healthy hand to be replicated on the impaired hand for proprioceptive training. The system aims to improve long-term rehabilitation outcomes for stroke survivors who require effective and engaging therapy for hand motor recovery.
Scrappy
Additive manufacturing has greatly improved rapid prototyping and small-scale production, but post-processing steps such as support removal, surface finishing, and print-bed cleaning remain largely manual and labor-intensive. These tasks introduce inefficiencies, inconsistencies in product quality, and potential safety risks due to exposure to chemicals like acetone used in vapor smoothing. Scrappy addresses this problem by developing a robotic system capable of automating these post-processing operations. By reducing manual labor and human exposure to hazardous materials, the project aims to improve safety, repeatability, and overall efficiency within additive manufacturing workflows.
SmartCan
SmartCan is a smart sorting bin designed to identify and collect recyclable materials using computer vision. Improper waste disposal and low recycling rates contribute to environmental issues, while individuals with mobility limitations may face challenges in properly disposing of waste. This project addresses both concerns by creating an autonomous system that can detect recyclable objects and move toward them. By combining accessibility with sustainability, SmartCan aims to promote cleaner environments and make recycling more convenient for a wider range of users.
Software-Defined Phase Array Radar for Near-Range Drone Detection
The signal strength necessary to identify small radar cross sections of miniature drones has resulted in most modern radars designed for this task being highly expensive and energy-intensive, rendering them impractical for use in an instructional setting and pushing university curricula to lean toward simulation as opposed to real-world testing. We are designing a cost-effective, energy-efficient phased array radar module using the ADALM-PLUTO software-defined radio (SDR), capable of detecting unmanned aerial vehicles (UAVs) at short to medium ranges. The proposed model may act as a replicable instructional platform for radar experimentation and a foundation for small-scale research in UAV detection and target classification.
Synthesizer Blocks
The project addresses the challenge of making analog signal processing and synthesizer operation accessible to beginners, since conventional synthesizers are often costly, highly complex, and difficult to interpret without prior technical knowledge. To address this, a modular educational system called Synthesizer Blocks was developed, in which individual signal-processing functions such as waveform generation, filtering, mixing, and amplitude modulation are implemented as physically interchangeable blocks. This architecture enables users to assemble signal chains while directly observing waveform changes through built-in test points, supporting a clearer understanding of electrical engineering fundamentals. The scope of the project included the design, fabrication, and validation of PCB-based functional modules capable of producing audible output while serving as a hands-on instructional platform for signal processing concepts.

The Impact of VCO Coupling with Control Voltage on Spurs
Phase locked loops are a critical component in modern communication, sensing, and imaging systems. While computer automated design tools allow for accurate simulation, they often take weeks of design and computing time. Our project's research intends to model a specific non-ideal performance of analog phase locked loops, previously not studied, as closed form equations. This allows designers to observe their system's performance in seconds, rather than weeks.
