Sound Canvas

Sound Canvas is a modified 16 channel mixer with 4 independent outputs. The original idea evolved was about translating sound into a traditional frame, which is a canvas in painting. This work exists as a patching system rather than a new invention of amplifier system only except pre-programmed chip that controls audio input/output signal - audio signal can be derived into 4 different outputs according to pre-coded program, random combination calculated by the microcontroller used, or twisting knobs on the mixer.

The whole idea of Sound Canvas is generating sound perspective, so that people re-examine their pre-conceived notion of sound. We often limit ourselves to think of sound only in 2-Dimensional space, but we are surrounded by sound that travels in 3-Dimension. Furthermore, we sometimes are distracted to experience sound in deeper level because of too much visuals. So, this sound canvas separates sound from visual elements, yet embeded on the familiar visual frame, allows audiences a chance to re-examine sound in deeper level. Plus, moving sound in quadraphonic sound system with relatively small space (we already have many surround sound systems such as THX, but we experience these in much bigger scale) creates an intimate engagement between this piece and audience.

Analog Octaphonic Sound Perspective Generator

Analog Octaphonic Sound Perspective Generator is a 8-channel sound mixter/passer that has 8 independent output channels controlled by photo censor. Originally, it was a site-specific project for the octaphonic sound system at CRCA, Center for Research in Computing and the Arts, San Diego, California. Moving images, or animated pictures are powerful. So does moving sound.

Digital Quadraphonic Sound Perspective Generator

Digital Quadraphonic Sound Perspective Generator is a qudraphonic sound system controlled by a joystick. It generates a simple tone, and user/audience can move the tone using the joystick.

Digital Sound Perspective Generator

Digital Sound Perspective Generator is a quadraphonic sound system controlled by a joystick through Basic Stamp, which is a programmerble microcontroller. By moving joystick, user can move a beep different dirrections. By engaging with this, audience/user is able to play with sound. In a sense, as we draw lines on a scratch paper, one can do the similar activity with sound.

Translator I & II

Translator I and II are simple interface systems coded with C++ and P-Basic. Using serial port, it gets information of bmp file. Then, it translate bmp file into binary data strip. Translated binary codes will be re-translated into sound (for Translator I) and light (for Translatoor II).

Temperature Wave

Art has been inspiring many people in many different ways. Nonetheless, it is very much true that disable people, such as the blind and the deaf, have not have enough chances to taste an appreciation of art. Since art, traditionally, delivers its theme through the medium, in which video or audio (or both) is highly involved, those disable people would not fully receive what an artist intends to give. There have been handful attempts to share the "art" with disable people, however it has been rare and still is on its experimental state.

One area of study that I can focus on for this project would be to come up with the mechanical devices that allow disable people to have a chance to taste a little bit of traditional 2-dimensional art pieces. One possible way to achieve this would be to come up with the metallic board that has many cells with various temperatures. Using the difference in temperature, blind people can feel various shapes. Another way to share this 2-dimensional artistic activity with blind people would be to make Temperature Wave, which is a heating element that moves between two ends of the board.

Temperature Wave will provide blind people a unique opportunity to feel the movement. It is not necessary for this project to perfectly reproduce the movement of wave. Instead, it will provide one possible way to share these 2-dimensional artistic activities with disable people.

Temperature Wave consists of two parts, and each part consists of three sections, which are Input/Sensing/Data-acquisition Section, Procession Section, and Output Section. The first part of the project mainly moves the heating element across the board. It has input through various switches and decides how fast the heating element moves and which way it moves toward. Second part controls the audio output. By putting the temperature sensor at both ends of the board, it can detect the location of the heating element. By using two speakers, L and R, it can create the sound perspective, depending on where the heating element locates.

Phototactic Drum

Phototactic Drum is an instrument that I built when I worked on Temperature Wave. I did not intend to build Phototactic Drum at the beginning, however, I ended up building one after failing to modify the sound outcome for Temperature Wave. The initial idea was to attach termistors, which vary the resistance depending on temperature, to Temperature Wave. However, termistors that I had worked with did not give me a sharp range to function properly. It only gave me the same beep sound regardless the position of the heating element. I built a speaker system that consisted of timer 555 chip with a potentiometer first and did not want to waste it. Thus, I ended up modifying a speaker system with a sulfide photocell resistor and created Phototactic Drum. The name of the instrument is from phototactic bacteria that move towards the light. The idea here is that a player has to move this instrument towards the light to play.
