From principle to practice.
Embedded hardware, flight systems, collaborative platforms, and the decisions that connect them.
Extreme Environment Drone Firmware
STM32-based drone firmware developed for extreme-environment research experiments, including embedded sensing and experiment integration.
CanSat — PCB & Firmware
PCB and firmware development for a two-tier CanSat system, including STM32 mother-unit control and ATmega328 child-unit firmware.
Cutist
An adaptive Pomodoro-style study assistant that adjusts session timing to focus patterns, presented at the IEEE SSCS Arduino Contest.
Custom BEC PCB
A custom battery eliminator circuit (BEC) board designed in KiCad and fabricated through JLCPCB for regulated power delivery in flight systems.
Y-Zipper Drone Wireless Charging Alignment
A Y-zipper-based mechanical alignment guide for drone wireless charging pads, built for the Nobel 100x100 competition.
Safe Fire
An IoT device that automatically removes a fire extinguisher's safety pin in an emergency, cutting critical response time during a fire.
BuildIt
An educational platform that fixes the code-review skill gap from AI-assisted ("vibe") coding, teaching top-down from real code to review fundamentals.
Borderless
A hackathon prototype bringing market-entry research, scenario comparison, bilingual workflows, and expert collaboration into a workspace for Korean startups exploring international expansion.
Delibot
An indoor last-mile delivery robot built on STM32 (mixed LL/HAL) and Raspberry Pi, using BNO080 IMU and encoder-based localization, with elevator integration for multi-floor delivery.
FTC Decode
Competing in the FIRST Tech Challenge (FTC) Decode season, building and programming a competition robot.
cbgpu
An all-in-one school life platform — GPU rental and server deployment alongside class timetables, self-study room applications, meal menus, discussion boards, study groups, and voting, all in one place.
