Engineering projects
From RF amplifiers to intelligent sensing systems — five builds, each rendered with its own live engineering visual.
Low-Cost Air Quality Device
Arduino ozone monitoring with a novel Adaptive Kalman–LightGBM (AKL/GBM) estimator. Manuscript under review at IEEE Sensor Journal.
S-band MOS Amplifier at 2.4 GHz
Single-stage 2.4 GHz MOSFET RF amplifier for Wi-Fi / BLE front-ends. Full EM and transistor-level simulation in ADS, fabricated and VNA-verified.
Differential Feedback DC-DC Converter
A novel differential switching-mode converter using two parallel SMPSs with inverted control to suppress ripple and improve stability.
VOC & PM Emissions from PCM Buildings
Multi-sensor ESP32 system with ML-based inference quantifying VOC and particulate emissions from phase-change building materials.
Custom MP3 Player
Standalone ESP32 MP3 player: microSD (VS1053) through an I²S amplifier on a fully custom PCB with real-time decode and physical controls.
