14-year-old boy makes wireless charger from waste
A 14-year-old boy used discarded items like wires, cardboard and junk lying in the house to make a wireless charger. He secured the first position at a science fair organised in the city by New Delhi Municipal Council (NDMC) last week.
A 14-year-old boy used discarded items like wires, cardboard and junk lying in the house to make a wireless charger. He secured the first position at a science fair organised in the city by New Delhi Municipal Council (NDMC) last week.
Vaibhav, a student of class IX at Navyug School, Mandir Marg, drew inspiration from a remote control car and its mechanism.
"I used waste materials like cardboard, copper wire, breadboard (a kind of plate on which one can place a chip), and resistors, capacitor for the chip," Vaibhav said.
In addition, two selfie sticks were used to make the antennae and receiver.
"The mobile charger works on the similar mechanism as that of a Samsung wireless charger. It has a transmitter on which the copper wire was bound 150 times. The receiver had copper wire which has been bound 50 times," he said.
The electromagnetic waves coming out of the transmitter are received by the receiver and hence the mobile starts charging. The wireless charger also has several pins so that cell phones of different companies can be charged."It cost me not more than Rs 300. The model was completed in one and half week's time," Vaibhav told DNA, adding the charger can cover a range of about 50 feet.
