About


Ever since I was a little kid I liked to open up electronic devices at my home and tinker with it to see what was inside! Since then I have been fascinated by this stuff like opening toy car, fixing the TV remote, making my own RC car. This love for electronics drove me to pursue Electronics and Communication Engineering at NSIT.

Interestingly, only after 5-6 months into my college life I came to know about CEDT(Center for Electronics Design and Technology) which helped to keep my love for electronics alive.
I did my schooling from Bal Bharati Publc School, Dwarka. My hobbies are virtual gaming, lawn tennis. Once or twice a year I like to go for adventure sports like river rafting, trekking.

1D Hourglass


In ancient times, hourglass was used to keep track of time and now although, it's usefulness has diminished but it has not become totally obsolete. So me with my 2 team members made a 1D hourglass with a single strip of LEDs simulating the falling sand. This project is powered by a 3.7V Li-Po battery and uses AtMega328p as the microcontroller. It consists of a selector switch to change the time. The beauty of this board is that it is a double sided board meaning it has components on both side of the board and it was produced inhouse at CEDT, NSIT. A small buzzer in the bottom beeps at the after the time is over.

Power Supply


This project was made by me in a team of three during winter training at my college. This was my first official project as a part of my curriculum. This project can be considered a stepping stone for designing any embedded system because power supply is the most basic element for any system. This is a linear power supply using LM723 as the regulator. This power supply is capable of converting 220V, 50Hz AC supply to a DC supply varying from 3V to 11V with a max. current of 500mA.

Kinetic Remote


We all know that alkaline batteries are a big threat to environment and it is a difficult process to dispose them off. So a circuit was made at CEDT which can be incorporated into any tv remote and it renders that particular remote batteryless. It uses a faraday generator as it's source of power. Faraday generator consists of a coil of wire around a tube and some magnets inside the tube. When the faraday tube is moved back and forth it produces electricity which is then converted to an appropriate voltage and then supplied to the remote.

Illuminated eye loupe


Ever heard of loupe!! Well the black magnifier that can be seen in the image is a loupe. Loupe is generally used by jewellers to look at small ornaments. But my professor thought why not attach a ring of LEDs around it and use it to look at the text printed on small ICs which is otherwise difficult to be seen by naked eyes. And the brilliance of the circuit is that it is powered by 1 AA battery and still driving 6 LEDs. This has been made possible by a circuit known as JOULE THIEF CIRCUIT.

Batteryless POV


POV stands for Persistance Of Vision. It produces a text with just a few LEDs arranged in a single line using persistance of vision. It can be used as an SOS signal in case of an emergency at a remote site.

LED Candles


We often see wax from our birthday candles spoiling our birthday cake, well who wants to eat wax! Then this project idea came to the rescue. The principle behind this projects is persistance of vision and multiplexing. This project has a couple of LEDs arranged in a matrix arrangement to simulate the birthday candles arranged on a birthday cake. Since bithday withoud a birthday song is no birthday, it has a speaker which plays a birthday song after all the candles are blown. And yes the candles(LEDs) have to be blown from your mouth!
