From a hand-held mobile charger to cloud networking for home appliances, meet Pune’s young ‘inventors’

60 students from 30 different colleges came together at Marathwada Mitra Mandal College of Commerce (MMCC), on Wednesday, for an intercollegiate science exhibition, ‘We-Gyan’ (Our-Science) 2017.

From redefining principles of resonance through a re-creation of a Chladni plate to a hand-powered mobile charger for campers and trekkers, 60 students from 30 different colleges came together at Marathwada Mitra Mandal College of Commerce (MMCC), on Wednesday, for an intercollegiate science exhibition, ‘We-Gyan’ (Our-Science) 2017.

Among them, a team of two seventeen-year-old students created an Internet of Things (IOT) project of ‘cloud-network for home appliances’ with the perspective to reduce wastage of energy resources at the basic level.

Students of Marathwada Mitra Mandal's Junior College of Science, Aditya Tambole and Vaishnavi Rewaskar, both in Class 11, created a mechanism whereby home appliances, including refrigerator, television, induction cookers and geysers, can be connected to a cloud network and controlled from a distance with a single tap on the mobile phone. “All these appliances have been connected to a hotspot which enables the user to control the working through his or her phone from a distance. For demonstration purpose, our design allows one to operate the appliances from almost 310 metres of radius. But if the principal is applied on a larger scale, it can have a much needed practical use,” said Tambole.

His teammate, Rewaskar, added that the objective of creating the project sprung out of the idea to save energy. “In our daily lives, such a system can be very useful for both homes and offices to help save electricity and man power, and that too, with accuracy,” she said.

Another student of MMCC, Sanika Patil, created a hand-powered mobile charger for trekkers and campers using the concept used in turbines to transform wind energy into electrical energy.

“Basically, I altered the rotating coil in the DC motor, manually. So a user is required to rotate the coil secured with a disk to manually create electric energy for the phone to charge. This can be extremely useful for trekkers or those who are in areas without charging points. Because, even if you carry power banks, once they lose charge, you need an electric source to charge it. On the contrary, this device can charge phones just by the motion of your hand,” Patil said.

At the We-Gyan 2017, these 60 students from junior colleges, were felicitated by the chairman of International Space Society and scientist at Indian Space Research Organisation (ISRO), Suresh Naik. Gufran Beig, project director of Pune, SAFAR (System of Air Quality and Weather Forecasting and Research), who was also present during the inauguration, visited each project station to encourage students to continue with their scientific research.

One such project was a mini-model of SAFAR’s air quality detection system, incorporated to detect gas leakage at home and judge the emissions, created by fifteen-year-olds Shubham Samal and Ashutosh Kadbhane fromSV Union High School & Junior College.

“When young minds merge their passion with logical thinking to re-create their understanding of the classroom scientific principles, it is a treat for both the eyes and the mind,” said Beig at the inaugural function.

Speaking to Hindustan Times, he added, “In Ahmedabad, SAFAR has connected with 230 schools to spread awareness and knowledge about air quality. This exhibition was one of the outreach programmes in Pune, but we wish to rope in more schools and colleges in the endeavour, for which, institutes need to come forward.”

Two teams from Dayanand Anglo-Vedic (DAV) Public School and Junior College, Aundh, won the first prize at the intercollegiate science exhibition and were felicitated by ISRO scientist Naik.
