High-Speed PCB Design (Raspberry Pi, DDR SDRAM & HDMI)
Problem: Routing high-speed digital lines requires stringent impedance matching, length matching, and crosstalk minimization to preserve signal integrity.
Method: Designed multi-layer PCB layouts using Altium Designer for Raspberry Pi integration, DDR SDRAM bus routing, and high-speed HDMI interfaces.
Result: Successfully generated production-ready Gerber files meeting strict high-speed timing and signal integrity rules.
Low Pass Filter Design & Measurement via Microstrip Technology
Problem: Designing high-selectivity planar microstrip filters requires rigorous optimization of insertion loss and fabrication tolerance yields.
Method: Applied the insertion loss method with Chebyshev approximation in Keysight PathWave ADS. Optimized, fabricated, and measured filter prototypes using Vector Network Analyzers (VNA).
Result: Achieved high correlation between simulated and measured S-parameters ($S_{11}$ & $S_{21}$) with robust yield statistics.
Arduino-Based Hand Gesture Control Robot
Problem: Developing intuitive human-machine interfaces for wireless robotic control using localized sensor feedback.
Method: Programmed an Arduino microcontroller in C++ to process real-time accelerometer/gyroscope gesture data and transmit motor control signals wirelessly.
Result: Delivered a responsive, low-latency robotic platform capable of directional tracking based on hand orientation.
Arduino-Based Obstacle Avoiding Robot
Problem: Real-time autonomous navigation requires rapid distance estimation and motor drive adjustments in unstructured environments.
Method: Built a robotic system utilizing an Arduino Uno R3, dual DC motor driver module, and ultrasonic sonar sensor for barrier sensing, combined with manual SMD/TH soldering.
