“There are many electronic systems in operation. They are very expensive. My system is much more advanced” regarding his new invention Suraj Prasantha said. He was made this invention by adding a 3G phone system to other electronic gadgets and circuits.

The system is installed at the entrance of a house and is connected to the phones of the house or a mobile phone. Phone numbers are connected to the main system. When an intruder enters the house an eclectic bulb lights up, a warning bell sounds, telephones or hand phones start ringing. With the use of 3 G technology scenes of the break in and any sound are recorded. Then owners of this house are able to take suitable action. He has spent about Rs 5,000 on his invention. Expenditure depends on the brand of 3G phone used.

”This is my first invention” said the winner of the Silver Medal, R P D Madusanka. “It is a security system for a house.” For his invention he has used an electronic circuit, some bulbs, a radio, 3G mobile phones an land phones. All the windows and doors in the house are connected with electronic gadgets to the main circuit.”

“When an intruder enters the house (fully secured or not) any time of the day, automatically all the bulbs in the house light up, 3G hand phones, radios, and land phones begin to ring giving signals to the owner of the house. Until the owner comes to the house and switches off the new equipment, they continue to operate. After that he can take suitable action,” He has spent about Rs. 4,000 on his invention.

This is the first time the Bronze Medal winner R A M M S Rupasinghe invented something. I am keen about new things. His invention, water level detector. When we want to fill the water tank of a house the motor must be switched on. When it overflows it must be switched off manually. I wanted to build a system that would operate the motor automatically. He has used a tube inside the water tank connected to the circuit.

With the new device, when the level of the water in the tanks reaches the top, the motor automatically stops without over flowing. When the tank gets empty the motor starts automatically fill the tank again. This system is quite easy for the house wives.

The three medal winners of this competition received their medals with certificates at a special prize-giving ceremony held recently at Colombo University.
