This course explores the use of radio, light and sound as media through which and artist can create a public voice. This course takes a hands-on, do-it-yourself approach to these media, providing a basic background in electronics theory and practice, as well as in programming and use of microcontrollers. Topics covered in this course include, but are not limited to, low-power radio, locative media, hactivism and culture-jamming. Some examples of activities include the construction of AM/FM radio transmitters and receivers, laser projectors, persistence-of-vision displays and mobile audio rigs. A survey of the artistic significance of these media will be conducted throughout the course. Students are expected to research and present their findings in class, as well as to produce a personal or collaborative final project that augments their own practices.
