    Nico: Bridging the Gap Between Musician and Tesla Coil
    (2014-09-14) Johnston, B; Bailey, J; McKinnon, D
    This paper describes the design and implementation of a new interface, Nico, which allows new and existing musical devices to control Tesla Coils. The interface uses an Arduino microcontroller to convert OSC and MIDI control data to TTL pulses that command the behavior of a Tesla Coil. This paper will give some background on the Tesla Coil, outline the design and capabilities of the interface, and will discuss the performance possibilities that Nico creates.

    speaker.motion: A mechatronic loudspeaker system for live spatialisation
    Johnson BD; Kapur A; Norris M
    This paper provides an overview of a new mechatronic loudspeaker system: speaker.motion. The system affords automated positioning of a loudspeaker in real-time in order to manipulate the spatial qualities of electronic music. The paper gives a technical overview of how the system’s hardware and software were developed and the design criteria and methodology. There is discussion of the unique features of the speaker.motion spatialisation system and the methods of user interaction, as well as a look at the creative possibilities that the loudspeakers afford. The creative affordances are explored through the case study of two new pieces written for the speaker.motion system. It is hoped that the speaker.motion system will afford composers and performers with a new range of spatial aesthetics to use in spatial performances, and encourage exploration of the acoustic properties of physical performance and installation spaces in electronic music.
