Specless: A device that dusts the chalk duster!
Four mechanical engineering students of Dayananda Sagar college of engineering, in Kumaraswamy Layout, have invented a device that cleans chalk duster. The device named ‘The Speckless’ is the brainchild of students Anchal Kumar, Ankur Aman, Ashish Agarwal and Avinash Yadav.
Anchal says, “The device can sense the presence of dust and clean the duster automatically. Hence, teachers and students need not waste time and energy on this task.” Ashish says, “Some teachers suffer from dust allergies and develop breathing problems due to chalk dust, which contains harmful chemicals. The Speckless will prevent this and definitely keep our teachers and students healthy.”
Chalk is generally made from the mineral gypsum (calcium sulfate) which is considered hazardous. Gypsum powders/dust may irritate eyes or sensitive skin and affect the respiratory system. Avinash Yadav added, “Our project is of social relevance. It makes a difference in our education system.” Ankur adds, “Apart from this, it also helps classrooms clean.”
Professor C P S Prakash, head of Dayananda Sagar college’s mechanical engineering section says, “Speckless is a good innovation by our students. These days, projectors, white boards and black markers are widely used in teaching. But the ‘Chalk and Talk’ method is still in vogue. When it comes to making the students understand concepts in detail, the Chalk and Talk method is preferred. In this context, the device will be of great use.”
