Projects
Condition Monitoring of DC-Link Capacitors
A current sensorless predictive maintenance system for real-time health monitoring of DC-link capacitors in motor drives. Designed a hybrid simulation framework by generating a synthetic capacitor degradation dataset in Python and modeling the drive system in MATLAB Simulink to extract realistic voltage ripple characteristics. An ESP32-based edge module processes the ripple voltage using FFT to estimate ESR and capacitance locally. These parameters feed an XGBoost model to predict the capacitor’s Health Index (HI) and Remaining Useful Life (RUL). Integrated with a continuous MQTT pipeline streaming to a custom Vercel dashboard.
View RepositoryPower Quality Analyzer via Hybrid Signal Processing
A low-cost power quality analyzer capable of detecting voltage sag and swell conditions in real time alongside PQ parameters computation. The system uses LEM voltage & current sensors, analog signal conditioning using operational amplifiers, and a TI C2000 F28027F microcontroller. Wavelet-based analysis (DWT db4) identifies disturbances, while Fourier-based analysis (FFT) works on harmonics. Final results are displayed on a Python-based dashboard.
View RepositoryrCalc – Resistor Color Code Calculator
A web-based resistor color code calculator that converts resistor bands to values and vice versa. Built using HTML, CSS, and JavaScript with responsive design and live preview.
View Live SiteAnalog PID Controller for DC Motor Speed
An analog feedback control system using LM358 op-amp to regulate the speed of a 12 V DC motor. The circuit realizes proportional, integral, and derivative control using discrete analog components, demonstrating practical PID-based motor speed regulation without digital processing.
Underground Cable Fault Detection System
A simulation-based system to detect the location of underground cable faults using the voltage drop principle. The system was implemented and tested in Proteus with ESP32, enabling real-time fault distance estimation and visualization.
View RepositoryBraille-to-Text Converter for Assistive Communication
Electronic Braille Input Interface using Arduino Uno that interprets 6-dot button inputs and converts them into alphanumeric characters on an LCD. Includes control functions (Alpha/Numeric mode, backspace, clear). Designed and validated using Tinkercad simulation.
