Featured Projects ⚙️ 3-Phase Motor Driver (in progress) Custom 3-phase BLDC / induction motor driver board. Power stage with gate drivers, shunt-based current sensing, DC-bus filtering, and microcontroller-side Field Oriented Control (FOC). Designed in Altium with attention to high-current routing, thermal relief, switching-node containment, and isolation between power and control domains.

Skills: power electronics · gate driver design · FOC firmware · high-current PCB layout · thermal management

⚡ Synchronous Buck DC-DC Converter (in progress) Step-down switching converter built around a controller IC driving high- and low-side N-channel power FETs. Inductor sized for target ripple current and saturation margin, output capacitance selected for ripple voltage and transient response, and a Type II/III compensation network for stable closed-loop behavior across load. PCB layout focused on tight input-loop area, switching-node containment, low-impedance return paths, and thermal handling for sustained load current.

Skills: synchronous switching topology · gate drive timing · magnetics selection · feedback / compensation design · switching-node PCB layout · efficiency analysis

🏭 Conveyor + Vision Sortation Cell (in progress) End-to-end automation cell: PLC-controlled conveyor with QR / barcode-driven part sortation. Real-hardware ladder logic developed on AutomationDirect Productivity Suite, with a parallel CODESYS + Structured Text implementation paired to a Factory I/O digital twin for offline validation, fault-injection testing, and HMI development before deploying back to physical hardware.

Skills: PLC programming · industrial vision · digital twin simulation · HMI design · state machine logic · sim-to-hardware workflow

🔊 Bluetooth Speaker System Stereo Bluetooth speaker built around the Microchip BM83 module and TI TPA3116D2DAD Class D amplifier. Hierarchical schematic in Altium, single ~100 × 100 mm board, LM1117-3.3 LDO with reset supervisor, BTL LC output filter, and star-grounded SGND/GND scheme. Antenna at board edge with copper pour exclusion for clean RF.

Skills: hierarchical schematics · mixed-signal grounding · power integrity · RF keep-outs · ERC clean

🎛️ 4-Track DJ Controller USB control surface + stereo audio output PCB. STM32F405 MCU, PCM5102A I²S DAC, TPA6132A2 headphone amp, and CD74HC4067 muxes for matrixed encoder/button I/O. Companion Python software (NumPy, scipy.signal, sounddevice) handles mixing, EQ, and effects. Hand-solderable packages throughout.

Skills: STM32 firmware · USB HID · I²S audio · matrixed I/O · system architecture
