PORTFOLIO DETAILS
This portfolio demonstrates projects I have worked on during my career as an OEM mechanical engineer, showcasing rapid prototyping, system electrification, and self-taught hardware integrations.
1. ELECTRIFICATION OF ON-BOARD DUST COLLECTOR
Converted a hydraulic-driven dust collector fan to an electric motor powered by a custom battery system, reducing physical and power constraints across equipment.
- Concept: Designed a system with two parallel 4.8kW, 48V batteries capable of 100A discharge. Designed active air cooling triggered by thermistor, vibration mounts, and ergonomic battery swapping enclosures.
- CAD & Manufacturing: Modeled all sheet metal parts, gaskets, and weldment in Inventor and OnShape. Final box was cut from sheet metal using CNC laser, bent, welded, assembled, and sealed.
- Testing & Iteration: Prototype successfully met fan runtime targets and thermal limits. Used testing data to pivot toward a more integrated, lighter battery pack closer to the skid-steer's COG.
2. PCB & PRODUCT DESIGN
Personal projects focusing on low-voltage electronics, precise PCB design, embedded software, and CNC/3D printing prototyping.
- Bicycle Headlight: Designed a portable LED headlight using EasyEDA. Created a custom schematic and PCB for the LED, LED driver, and charging circuit. Sourced SMD components and meticulously performed reflow solder assembly.
- Watch Design: Conceptualized a battery-powered, water-resistant smartwatch with a detachable wrist-strap. Built STM32 microcontroller boards in KICAD for PWM motor control and LED handling to build firmware foundations.
