Boy builds drone in Kolkata!

Most boys his age would be happy with a bike. A car would be a dream. But Subhanjan Saha owns a drone. Better still, the 21-year-old 'technopreneur' has built it himself and claims to have outdone similar campus innovations inspired by Joy Lobo's flying spy camera in '3 Idiots'.
Built with scrap metal, pieces of plastic and cheap Chinese-made contraptions, it packs enough power to fly 10km at a stretch at a height between 5,000-10,000 feet, take clear ground photographs with a high-resolution camera and instantly relay them back to its operator. Saha has also equipped it with "bomb-dropping" and "rocket-launching" abilities. Saha's manufacturing cost for the drone was Rs 90,000.
The third-year computer science student at Manindra Chandra College has written to the Defence Research and Development Organization for help and funds. If he can develop it to the level he desires, Saha believes the drone will be good enough to be used by the Army for surveillance and security operations, especially along the turbulent borders with Pakistan and China.
