‘Smart Dustbin,’ an ingenious automatic dustbin designed by the 5th Semester Students Bachelor of Computer Application of Department of Computer Science and IT, Patkai Christian College (Autonomous) won the top prize at the college’s ‘Science Exhibition 2022.’
A total of 50 models were presented and submitted by students for competition at the exhibition held under the theme ‘Integrating Science and Skills’ at the PCC’s Science complex on October 7.
The 5th Semester students of Bachelor of Science, Department of Chemistry won the second prize for their “Cotton Candy Machine” while their counterpart in the Department of Physics took home the third prize their “Speed Breaker Power Generator.” The winner received prizes and certificates sponsored by Dr N Savino, Associate professor SASRD, NU and Apcon Enterprise, Guwahati.
Meanwhile, as per students, ‘Smart Dustbin’ automatically opens with the help of a servo motor and sensor detect the object in front of the dustbin.
The advantages of using ‘Smart Dustbin’ in the larger context, included reduction in the number of waste, maintenance of environmental hygiene, decluttering and improving the street scene and drive down carbon emissions, the students presented.
It further encourages recycling-on-the-go-by ensuring litter bins are not over-flowing and residents would be encouraged to put the right thing in the right bin, they added.
Meanwhile, Cotton Candy Machine was presented as a simple hollow metal cylindrical container about 5-6 cm in height and 7 cm in diameter with holes as well as DC motor and a battery for the energy to run the machine.
In the modified pollution-less model, the candy is produced using only normal melted sugar without added chemicals, the presenters explained, adding that it is a low-cost machine with a total cost of only Rs 500 as compared to the one available in the market for over Rs 3000.
Speed breaker power generator was proposed as machine that produces power ‘non-conventionally’ by “reciprocating motion of the speed breaker is converted into rotary motion and generates energy from it.”
This mechanism is very economical and with proper arrangements, can generate high power electricity from road traffic, the presented submitted.
The judges of the exhibition were Dr Nazrul Haque, Principal Scientist, ICAR- NRC on Mithun, Medziphema; Dr Thingujam Jackson Singh, Assistant Professor & Head of Department of Mechanical Engineering NIT, Nagaland; Dr Renchumi Kikon Kuotsu, Department of Political Science and Rallo Patton, Department of History, PCC.
As per a judge, the models, among others were assessed on new invention, whether new ideas have been added existing techniques as well as usefulness and applicability.
Meanwhile, clarifying on an earlier report, the organisers informed that students from five schools attended the event but did not exhibit their models.
