What’s the Big Idea?
A horn with targeted sound heard only by those for whom it is meant and a study table where the user can generate electricity while studying.
Manibhushan takes studies very seriously and both his ideas help students study well.
He earlier lived in Dhanbad which had frequent power cuts. Studying at night became a problem. So, he thought of a study table that generates electricity that can be used to power a bulb.
Later, in class 11th, he shifted to a school in a bigger city. He stayed near a busy road with a lot of traffic. Sometimes, he could not even talk to his parents over phone because of the loud honking. This is when he thought of this idea to reduce noise.
A honk is usually meant for the driver of the vehicle in front. However, it is heard by everybody in the area, creating noise pollution. In Manibhushan’s horn, the sound directly reaches the target with no noise going into the surrounding environment.
It has emitters to give a signal (infrared or ultraviolet) and sensors to detect the signal. When the horn is pressed, signals are transmitted instead of sound. These signals are picked up by the sensors in the car in front. This triggers a beeping sound and a light signal to alert the driver that somebody in the back is honking.
What’s more, the cost of this horn is similar to a regular car horn.
Study table that generates electricity
Frequent power outages made studying at night a big problem. So, he thought of a study table which has a pedal for generating power using a dynamo, like in bicycles. A battery is used to store this energy that can be later used to light up an LED lamp. It also has a small fan. “About one and a half hours of pedaling can generate sufficient electricity to run a small fan or light bulb for four to five hours,” claims Manibhushan.
Mad about Machines
Manibhushan loves machines. As a child, his favourite television program was ‘Small Wonder’. Its main character was a highly-advanced robot that looked like a little girl. One day, they showed that the robot was broken and the scientist who had created it fixed it by using a small chip. “I thought that the chip was very similar to a black extension of my antennae. So I went to the roof and broke a part of the antennae, confident that now the chip was with me, I would also be able to make the robot. Of course, the robot never got made and I ended up getting scolded for breaking the antenna,” he says while laughing.
Father as Role Model
His father is a scooter mechanic. Even though they did not have a lot of money, his father sent him to a good private school.
One of his favourite memories of childhood is going to school, sitting in the front on his father’s bicycle. “My father would point to any object on the road and ask me ‘What is that?’ If I said ‘crow’, he would then say, ‘okay, how do you spell it?’; then he would say, ‘Now, can you make a sentence with it?’ He gave me a strong foundation so that today I can study on my own without wasting time and money on tuition classes,” he says proudly.
Hopes & Dreams
Manibhushan wants to be businessman, but would also like to act in films. With his spirit of hard work and hope, he is confident of making his dreams come true.
Note: Manibhushan won IGNITE in 2010 as a class 11 student and a Consolation Award under the Student Award category in the Fifth National Biennial Awards in 2009. NIF supported him in creating a working prototype of the study table. A patent application (1247/KOL/2010) for the noiseless horn has been filed by NIF in his name.
