Seeing power with a flashlight: DIY thermal sensing technology in the classroom

Abstract

This paper contributes to the growing literature on ‘making and doing’ in Science and Technology Studies (STS) by describing and theorizing the teaching of making and doing. We describe a collaborative do-it-yourself (DIY) technology project taught simultaneously in Canada and the United States, in sociology and public health, to undergraduates with no prior electronics experience. Students built thermal flashlights – low cost digital tools for making thermal images – and employed them to research their surrounding environments. By making and using the thermal flashlights, learners investigated power in two senses: identifying social power relationships embedded within normally unquestioned infrastructures, and exploring these infrastructures’ connection to industrial forms of power, such as heat and electricity. Students and instructors came to understand how the control of power, light and temperature is vital to human-made infrastructure and environmental health threats that characterize the 21st century. Through this project, students went from being passive consumers of such power to become active investigators of their socio-technical systems by producing unique knowledge that enabled them to imagine how they might make and inhabit their environments differently. Breaking down the distinction between teaching and research, this article explores the promise of ‘making and doing’ in university courses to create new collaborative research platforms that could spread laterally and scale to transform social and technical infrastructures.
