Personal Projects


Radar Vision desktop aircraft radar display

Custom 3D-printed aircraft radar display

Personal Project — Radar Vision

Designed and fabricated a custom mid-century modern-inspired enclosure for an open-source ESP32 aircraft radar project. The project involved CAD design, 3D printing, soldering and wiring electronics, hardware integration, software configuration, and final assembly to create a polished desktop display.

Tools & Skills Used:
CAD 3D Printing Electronics Integration Product Design

The enclosure was designed in CAD with a focus on product aesthetics, manufacturability, and ease of assembly. Inspired by mid-century modern television designs, the housing incorporates mounting features for the display, controls, and electronics, along with a removable rear panel secured by embedded magnets for tool-free access. The geometry was optimized for reliable 3D printing while producing a clean, consumer-style appearance.

This project required integrating the display, controls, and electronics into a custom-designed enclosure while ensuring reliable electrical connections and clean internal cable routing. I soldered and assembled the hardware, configured the open-source ESP32 radar software, and performed system testing to verify proper functionality. The completed device highlights skills in electronics assembly, system integration, debugging, and product development.

Cloud-connected desktop idea printer

Personal Project — Idea Printer

Designed and built a custom desktop idea printer that turns text messages into physical reminder notes. By integrating a Telegram bot with a cloud automation workflow, ideas can be submitted from anywhere and automatically printed as receipt-sized notes to pin on an idea board.

Tools & Skills Used:
CAD 3D Printing Telegram Bot API Automation API Integration Hardware Integration Product Design

The enclosure was designed to turn a standard thermal receipt printer into a compact desktop appliance. The housing provides access to the paper slot, controls, and power while giving the printer a cleaner finished appearance. The design was optimized for 3D printing and practical assembly.

A Telegram bot receives ideas from my phone and sends them through an automation workflow to the receipt printer at home. This allows quick ideas to be captured from anywhere and turned into physical notes that can be saved, organized, or pinned to a board.

The project integrates the thermal printer, custom enclosure, power connections, and cloud-connected messaging workflow into a functional desktop system. The final build demonstrates hardware packaging, system integration, automation, and practical product development.

Capstone Projects


Saturn Strap Housing
Saturn Strap Assembly

Capstone Project 1 — Saturn Strap

Worked with a multidisciplinary team to design and prototype the Saturn Strap — an innovative football helmet chin strap developed for startup Saturn Sports. The device measures strap tension and alerts players when the strap is too loose, improving helmet safety.

Tools & Skills Used:
CAD Mechanical Design Prototyping Sensor Integration Product Development Testing & Validation

The Saturn Strap design was constrained by existing football helmet patents, limiting modifications strictly to the chin strap housing. As a result, the design prioritized functionality over aesthetics while ensuring compatibility with current helmet systems. A rotating cylindrical mechanism was developed to allow the chin strap to pass through the housing, where sensor-based rotation measurements were used to determine strap tension. This approach enabled accurate fit detection while maintaining a compact and durable mechanical design.

Testing of the Saturn Strap focused on validating sensor performance, system reliability, and overall functionality under realistic use conditions. The prototype was evaluated by measuring chin strap tension and confirming proper system response through an LED indicator system, which displayed red when the strap was too loose and blue when proper tension was achieved. To improve accuracy across different users and helmet configurations, a calibration mode was implemented, allowing the system to establish a baseline tension value before operation.

Working directly with a client added another layer of complexity, requiring the team to balance technical performance with real-world usability and design constraints. This experience strengthened skills in communication, adaptability, and engineering decision-making while emphasizing the importance of meeting client expectations within technical and patent-related limitations.

Calibration Cart Testing

Capstone Project 2 — Dayton Photonics Calibration Cart

Worked with a team at Dayton Photonics to design and build a calibration cart for the company’s Theia optical testing unit. The cart was designed to precisely pan and tilt while supporting up to 70 pounds, allowing for accurate and repeatable calibration positioning.

Tools & Skills Used:
CAD Mechanical Design Load Analysis Pan-Tilt Mechanisms Prototyping Client-Based Design

The Dayton Photonics calibration cart was designed to support and accurately position the company’s Theia optical unit, with primary design constraints centered around load capacity and controlled motion. The system was required to safely support a minimum load of 70 pounds while maintaining smooth and repeatable movement.

The final design incorporated a custom mounting interface, a 360-degree pan mechanism, and a ±50° tilt range, allowing precise alignment during calibration procedures. Structural components were selected and sized to ensure rigidity under load while maintaining ease of adjustment and transport.

Testing focused on verifying load stability, smooth motion through the full pan and tilt range, and overall structural integrity under operating conditions. The project emphasized mechanical design tradeoffs, load analysis, and practical manufacturing considerations, while reinforcing the importance of designing to real-world constraints and client requirements.
