Signals over Syntax

Hi. I'm Chinmay.

Once a web developer. Now a wireless comms researcher with a thing for RF, Signal Processing, and Machine Learning — building systems for real-world defense applications. Researching at the edge — literally.

The CS Foundation

Like most freshmen at NIT, I followed the herd — diving into web dev and DSA because it was the thing to do. Those projects taught me how to build, sure. But they also sparked a deeper question: Is this really what I want to build? Turns out, my real curiosity was waiting in circuits, signals, and the invisible world of wireless.

Hardware & Machine Learning

Bridging the gap between the physical and digital, I explored everything from microcontrollers to deploying machine learning models on edge devices.

Arduino Room Monitor

Arduino Room Environment Monitor

My first hands-on project in ECE. A simple yet fundamental system using an Arduino to display real-time room humidity and temperature on an LCD screen.

Arduino, Embedded C, Sensors
Warehouse Bot

Warehouse Automation Bot

A Digital Systems Design project involving a bot for RFID-based cargo retrieval. I developed the state diagrams, K-Maps, custom PCB schematics, and implemented the MIMO controller in Verilog.

Solar Potential Tool

Solar Potential Estimation Tool

A web-based tool analyzing satellite images to calculate solar potential. It generates heatmaps on buildings and estimates power output. The basis for my IEEE research paper.

UNet, UNet++, Python, QGIS
Soil Sensor

Non-Contact Soil Moisture Sensor

Co-authored a technical paper on a system that uses a webcam and an SVM model deployed on a Raspberry Pi to determine soil moisture levels (dry, optimum, saturated) from an image.

Deep Dive into Research

Collaborating with esteemed institutions, I delved into advanced topics like satellite communications and signal processing, contributing to cutting-edge research.

GPS Receiver

Indigenous GPS Receiver

A project in collaboration with the Indian Army Signal Corps. I captured and processed raw live GNSS signals using RTL-SDR and GNSS-SDR, comparing results with our in-house MATLAB scripts.

DOA Estimation

DOA Estimation @ IIT Madras

My largest ongoing project with the TelWise group. I developed a FFT-based "beamspace" MUSIC algorithm, achieving an 8x speed improvement over traditional variants for Direction of Arrival estimation.

Technical Paper

We present a cost-effective, non-contact method for soil moisture detection by deploying a Support Vector Machine (SVM) model on a Raspberry Pi, which classifies soil images captured by a webcam.
