Young scientist draws attention at congress

Staff Reporter

NIZAMABAD: With the increasing incidents of children falling into uncapped borewells and dying of suffocation, the scientific equipment invented by a young scientist of this town is considered to be very useful in the “damage control” exercise.

The Young Scientist Award winner N. Ramesh Reddy is back in news once again with this device which was displayed in the ongoing 95th Indian Science Congress in Visakhapatnam.

New contraption

Presently there is no such equipment to observe the condition of the person who falls into the narrow hole.

The rescuers sit their fingers crossed until the victim is brought out of the hole. But, by the time the person may die.

With the new contraption operating with a transmitter can identify the child got stuck in the hole and enables the rescuers to hear the noise and view the victim’s movements.

It works with an LCD camera weighing between 50 and 75 grams and needs no power for its functioning.

An 8v chargeable battery is fixed in this wireless camera which sends signals to a distance of 50 mts.

This is lowered into the bore-well hole with the help of a wire. It receives video and audio signals and sends them to a transmission, a combination of two aerials, 6 pc capacitors, two Ics, 6 E.C. capacitors, 10 diodes, eight resistors and two transmitters.

Cost factor

Receiving signals from camera it modulates the waves into electromagnetic waves.

This also filters and improves the signals capacity.

Receiver can be placed near a television to view the position of the person in the monitor. It can be fixed within 5 minutes and costs not more than Rs.750. “We can also use this device as a small TV station,”

Mr. Ramesh Reddy told The Hindu over phone from Visakhapatnam.

Mr. Reddy, a Post Graduate in physics from Osmania University hit the news with his soapbox transistor and many other interesting devices and won the Best Young Scientist Award in the year 2006.
