performance based experience
My initial concept is to create a laser projector that is controlled by audio data from cassette tape loops. The mixture of analog and digital media will make for an exciting experience.

Analog tape loops are an old method of making repetitive samples, this method has been replaced by digital samplers and computers. The advantage of using cassette tape is it is more physically tactile than using digital devices. This advantage is important when interacting with musical devices, a good example is the preference of a dj to use a vinyl turntable over a digital substitute. more about tape loops
The use of lasers to visualise audio is common but the visual result is usually forms made by curved lines. A common method of achieving this is directing a laser at some mirrors that are mounted on speakers. The difference in my project will be that the projection will a rectangular screen of monochrome moving image. While the picture won’t look quite as sharp as a video projector, it will have a unique look.

The laser beam will be directed by two mirrors, each connected to a stepper motor and the brightness of the laser beam will be changed by different currents. The two stepper motors will accurately point the beam of light in a horizontal and vertical direction.
