Vedant is no ordinary kid. While other children throw away broken toys and buy new ones, he collects the scrap from his discarded ones to make new and ingenious gadgets.
Vedant Dhiren Thaker is a student of Class 6 in Shantinagar High School, Mira Road, Maharashtra. Like many other kids his age, broken toys are a regular feature of his growing years. But, not all his toys break accidently. Some of them are disassembled carefully and all the electronic parts obtained from inside saved.
Vedant is interested in using these broken parts – the remote controls, magnets, batteries, etc. — to build new things, things that are completely different from the original toys.
So, when one of his remote control cars broke down recently, he decided to use it to make a device which would help him solve a daily household problem for his mother.
“During my summer vacation, I keep going outside the house many times. Many of my friends also come over frequently. The doorbell is constantly ringing and every time it goes off my mother has to leave whatever she is doing to open the door. I realised that this was a troublesome task and my mother used to get irritated at times,” says Vedant.
Vedant decided to do something to help his mother. He put his gadget-loving brain to use and made a remote control door operating device with the following spare parts obtained from a broken remote-controlled toy car:
· Remote control
· The motor drive mechanism circuit
· Rechargeable batteries
· The remote control (RC) circuit used inside the car
Vedant connected these to make a prototype device that opens the lock of the main door in his house with a remote control, and has enough range to be easily operated from any part of the house.
His mother can now open the door from anywhere, without having to leave the work she is doing.

For those who want to know how exactly the device works, here’s more:
(Geek Alert: Read at your own risk)
An RC car has a transmitter in the form of a remote control, and a receiver in the form of an antenna and a circuit board placed inside the car. There is a motor drive mechanism which turns the wheels and operates the steering of the vehicle. Finally, there is a power source in the form of rechargeable batteries.
For functioning, the transmitter sends Radio waves as the control signal which drives the motor, leading to the specified action (like rotation of wheels or steering), which then causes motion in the car.
Vedant utilised this entire process for the working of his device.
He attached the RC circuit, along with the motor drive mechanism of the car, to the door. The RC circuit also includes the antenna. From the remote control of the car, he sends radio waves to the antenna, which then gets transmitted to the motor drive mechanism through the battery. This rotates the shaft of the gear box. Vedant has connected the shaft to the latch of the lock with a simple nylon thread. As the shaft rotates, the thread winds itself, thus pulling the latch, and the door opens. When the remote switch is released, the latch goes back to its original position.
“He never keeps any of his toys in their original form. Always makes something new out of them,” says Vedant’s father Dhiren. With his wonderful and inspiring curiosity, Vedant has built numerous things like electronic boats, a power source, and crackers made from scrap.

Kudos to the young genius and his love for electronics!
