Sewing is one of the oldest textile arts which are still popular among the masses of India. Beyond being an art work, sewing serves as a source of livelihood for millions of people. In modern India the major part of the sewing industry is confined to the rural villages spread across the north and the north eastern states of India. Most of these villages are still to receive electricity and those of whom have, are sustaining on the verge of energy poverty. The operation of a sewing machine can be harnessed to produce electricity for small scale purposes. This can be used for charging batteries, mobile phones, lamps, emergency lights. The rotational aspect of the sewing machine wheel can be used to generate power. Power generation is facilitated by using an Alternator. The usage of an Alternator over a DC Motor or Dynamo has added advantages which are described in detail in due course. This paper is intended to present a method to generate power by effectively harnessing the rotational capability of a sewing machine wheel. The paper also deals with the advantages of using an alternator over other electricity generating devices.
All undergraduates (UG) who set aside research for faculties and professionals are not only missing interesting moments in their graduation, but also fail to grab the extra bit of information which will assist them in their career. Formal education is an integral part of learning but research experience gives hands on experience which class room coaching fail to deliver. These activities not only enhance technical skills but also develop vital life skills like team work, communication skills and problem solving ability. The style of project submission and reviewing gives the student an overview on industrial product development cycle. A Humanitarian Technologies lab established in our institution gave us ample opportunity to work with projects which benefit human life. In this paper we present the research work we carried out in pulse oximeter design and implementation, and thereby bring out the UG research experiences -benefits, challenges, knowledge developed, expertise acquired etc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
