PhantomRx
PhantomRx is a 3D-printed, sEMG-controlled bionic hand designed to help alleviate phantom limb pain (PLP) in amputees. Phantom limb pain is a neurological condition where individuals experience sensations or pain in a missing limb, often due to disrupted nerve signals. PhantomRx uses surface electromyography (sEMG) sensors to detect electrical activity in the residual muscles of the amputated limb. The system translates these signals into realistic hand movements, providing visual feedback to the user, which helps the brain re-establish its connection with the missing limb. The project also explores reverse nerve feedback through low-current electrical stimulation, applying small electrical currents to the residual limb in response to the detected muscle activity. This novel technique aims to reduce PLP by restoring the brain’s expected sensory feedback loop. Through extensive research into neuroscience and prosthetics, I discovered that combining visual and nerve feedback offers a more effective solution for managing phantom limb pain. This project introduced me to bioengineering principles, neuroplasticity research, and the potential for low-cost assistive devices to improve the quality of life for amputees.
AQI monitor
Air Quality Monitor designed for bad air days in Delhi NCR. This handy equipment continuously monitors the air quality and indicates on the display. The equipment is for use by society guards to indicate the air quality so that they can start using masks whenever the air quality is in Unsafe zone. I intend to plug this to our wifi and whatsapp so that it send a message to the society group for necessary action whenever the air quality goes below the safe threshold.
sEMG Bionic Hand
I have been working on a Bionic Hand prototype, with the aim of helping the differently abled. The unique feature of this prosthetic is its ability to amplify very weak nerve signals, fed into it via electrodes, whenever the muscles are flexed just below the elbow. These signals are then converted into hand movements based on the gestures made by the user.
Its main features are:
-
Recognizes three gestures (wrist up, wrist down, fist close)
-
Individual Finger control
-
Detects signals from the forearm extensor and flexor
Mercury Racing
F1 in schools is a program developed to introduce students to STEM subjects in the most engaging way possible – through the creation of a miniature F1 car.
As a design and manufacturing engineer, my target was to engineer one of the fastest cars. My aim was to design a car with a very low drag coefficient and build a structurally sound and yet light car within the given constraints.
Our team, Mercury Racing, qualified for the National Finals where our car was amongst the top 5 fastest cars. I am still working on making "the fastest" car in the next round.
Model Rocket Launch
My hobby project in winter break
3D printed Wrist Brace
A 3D-printed wrist brace that is printed flat on the bed. This brace uses the low melting point of PLA to shape the brace perfectly to anybody's wrist shape by dipping it in boiling water.I explored the process of PLA molding from this project and am diving deeper by making thumb splints and ankle braces.
Filter Straw
This is a 3D printed 3-stage water filter, The first stage consists of an open pore sponge to remove solid impurities from the water. The second stage contains activated charcoal to remove chemical impurities. The final stage consists of pure iodine crystals to remove any pathogens and viruses.
The straw is coated with sealant since FDM printers can not produce water-tight prints.
Arduino Based Drone
This is a drone that I built using an Arduino Uno-based flight controller which is connected to an Arduino Nano-based drone transmitter. The flight controller runs on the Multiwii software which makes it easy to calibrate the Gyro and Accelerometer.
This project taught me a lot about Brushless motors and radio modules interfacing with Arduino. It also taught me how to use different software and electronic speed controllers with Arduino.
Watch Winder
After buying my first automatic watch I soon encountered a problem, the watch would unwind after just a day of not wearing it. I started searching for solutions and figured out that an automatic watch winder would be the best solution. I started designing the 3d model and 3d printed all the parts, after the printed parts were with me I attached the stepper motor to the mount and connected it to a stepper motor driver. I programmed the Arduino to move the watch clockwise and counterclockwise in 10 seconds intervals.
Joystick Controlled Bot
This was a simple Pan and Tilt robot I created to mount my nest camera on to monitor my 3D printer from different perspectives. It runs on an Arduino which is connected to 2 servo motors that correspond to each movement Pan and Tilt.
The frame of the robot is 3D printed in PLA and it is attached to a piece of wood to keep it stable during testing. The frame has been completely designed by me and the code has also been written by me.
DIY Nerf Gun
This is a 3D printed nerf gun which is completely DIY except for the magazine which is from an old Nerf gun I used to own.
The gun is called a Gryphon and works using an Arduino Pro Micro paired with 2 brushed dc motors in the shooting mechanism as well as a micro switch for the trigger.
This was one of the most advanced projects I undertook since I wasn't well-versed in Arduino programming or 3D printing.
Snack Dispenser
The snack dispenser I made is a unique creation that dispenses snacks at predetermined time intervals. it ensures that snacks are always available to help you stay energized and focused.
Built as part of a course by Mark Rober, the dispenser features a sleek and modern design, with a durable outer casing that can withstand frequent use. The dispenser's mechanism is controlled by an Arduino microcontroller, which is programmed to dispense snacks at specific intervals throughout the day.
Custom Gaming PC
This custom-built Gaming computer was a dream come true for me. Since Covid had confined us to our homes my friends and I had taken up gaming to occupy our time.
I knew I wanted a PC as soon as I started playing video games. After a few months of casual gaming, I decided I wanted to build my own Gaming PC, equipped with knowledge from multiple youtube videos I started designing my PC. Nothing could have prepared me for what was about to come. I thought it would be a walk in the park once the parts arrived. Soon after, I realized what I had gotten myself into, however after many grueling hours with my father it was finally ready.
Once the PC was built I could not wait to flex on my friends. The feeling of building the PC myself was what got me so interested in DIY projects and later engineering.
Split Mechanical Keyboard
Pegboard
I had noticed that I would feel pain in my wrist whenever I would spend a lot of time on my keyboard. One day I decided I would make a mechanical keyboard that would use a split keyboard layout. The case of this keyboard was 3d printed and consisted 70 switches. since the PCB for this particular keyboard was not for sale in india I hade to hand solder upwards of 200 joints.
Smart Dustbin
The aim of this project was for me to make a dustbin which would open when I would put my hand in front of it. I need this for my table as the bin would be stationed on top of my computer and was very hard to reach. I use a simple circuit which consisted of an ultrasonic sensor a servo motor and an Arduino. This was the first time I was building a project with an Arduino, which introduced me to circuitry and some programming.
Object Detection - CCTV Camera
For this build I wanted to make a surveillance system that would monitor our home 24/7. I use a Raspberry Pi, a webcam and Motion Eye OS firmware to make this project possible. I wanted to add a feature in which the camera would send us an alert whenever someone was at our door and would also send us a recording of who it was.
