About Me

Hey there! I am Rohan. I am a junior Electrical Engineering and Physics Student at Texas Tech University. I have a deep passion for building things and understanding the nature. I started programming when I was 15 to build mobile games. Ever since, I have worked on games, apps and hardware projects. Apart from that, I love to read. One of my all time favourite books is Lord of the rings (search the flag at the top :p). Below are some of my relevant projects:

Projects

Mentis AI

Mentis AI Mentis AI 2 Mentis AI 3

Summer of 2025 I came up with the idea of Mentis AI, to develop a proof of concept device that provides low friction interaction with a personal AI assistant. Project was funded by Honors College and the professor whose lab I worked in. Currently, exploring the potential applications of the device, possibly in providing aid to vision impaired individuals. Project won a social entrepreneurship challenge with a cash prize.

Technical Summary

I designed the PCB, wrote the firmware, handsoldered all the tiny components and wrote a python server that runs 24/7 on an AWS EC2 instance, and a pairing mobile app that connects to the server. User wears the device on their ear, they press the button and speak. The microphone records and simultaneously streams the audio to the server in UDP packets. The server receives the bytes, and sends it to OpenAI API then receives the response and sends back the response to the device over TCP which plays the response on a transducer (functioning as a bone conducting speaker). Also the device is rechargeable via USB-C.
Check out my github for more details.


P.S. Not a single one of these things was taught in my coursework, I learned everything on my own :).

UXO detection Hexacopter

Hexacopter Hexacopter 2

This is a custom built hexacopter drone that will detect unexploded ammunition in Ukrainian conflict zones. This project was being developed by 1 graduate student and 2 senior undergraduates. All of them graduated, now I am the sole person working on this project. I am responsible for getting the drone to fly and integrating the GPR sensor that will be provided by another lab. My goal is to finish this before summer 26 starts.

Flyover Drone

Flyover Drone

This is a flyover tricopter drone that will fly over a stadium on campus. Just like the project above, I inherited this one.

Height measurement

This is a notable project from my highschool. Inspired by a physics problem that one can know height from the time of drop, I built a 7ft electromechanical wooden contraption to measure a person's height. User stands on the platform, pulls a lever that presses a button and releases a string connected to a small wooden block. The arduino starts the countdown until objects reaches the ground, cuts a laser mesh and blocks the light beam going into photoresistor. Arduino then uses equations of motion to calculate height of fall i.e. height of the user, and displays on an LCD.
It didn't work perfectly but it was fun to build! (though I built another one that used sonar sensors and was much simpler, it worked fantastically. It was like a battery-powered height scale).

And many other tiny tiny projects.

Software Projects

(all made in pre-vibe-coding era)



Tech Schedule

A mobile app for Texas Tech University for students and instructors to see their active schedules of the day. Instructors can remotely edit their schedules that will be reflected on students' apps.
I scraped all courses data and faculty emails and put them in a Firebase Realtime Database. Hashed all course data for quick retrieval. Made the mobile app in Expo React Native. Used Firebase Authentication for user login.

P.S. I am not actively maintaining any of these projects, so they are not available on app or play stores.

Books

Here are some of my favorite books that I think everyone should read:

  • The Lord of the Rings
    The Lord of the Rings J.R.R. Tolkien

    The imagination of Tolkien is beyond words. No book has had more moral impact on me than this one.

  • The Blind Watchmaker
    The Blind Watchmaker Richard Dawkins

    Dawkins explains how complex beings can arise from a surprisingly simple process. Builds deep intuition for seemingly unintuitive idea.

  • The Selfish Gene
    The Selfish Gene Richard Dawkins

    Classic. My first book that got me fascinated with evolutionary biology.

  • The Invention of Nature
    The Invention of Nature Andrea Wulf

    Biography of Alexander von Humboldt. His intense curiosity to explore and understand nature is fascinating.

  • Surely You're Joking, Mr. Feynman!
    Surely You're Joking, Mr. Feynman! Richard Feynman

    Funniest book I have ever read.

  • How Innovation Works
    How Innovation Works Matt Ridley

    A must read for engineers or those involved in technology. Ridley explains the evolutionary nature of innovation contrary to the "Eureka!" myth.
