Through this project, The Artist wished to explore the fringes of acceptable signal loss. The first phase included distorting the signal. By porting an RCA video signal through an RF Modulator, one level of quality was lost. Adjustments available on this specific model of Modulator allowed the vertical sync to be distorted, further degrading the signal. On the audio end, the first idea was to use an amplifier to pump the audio out at an extremely high amplitude and into a pair of extremely small speakers. The ensuing peaks led to a highly clipped and distorted sound. However, the distortion was too great. The Artist took a detour, and attempted to construct his own speakers from the most unlikely source - nonworking computer hard drives. The idea for this was sparked by Dj Afroman, the alias of an Electrical Engineering student at Carnegie Mellon University. A simple Google search for "hard drive speakers" will give you all fo the information The Artist had at inception. The experiment was a success. The sound level was low - too much amplitude caused the motor arms to clatter angrily, drowning out any sound that was made. At the lower level, sound was clean and understandable, but the listener must be very close to the source. Perfection was reached by routing the video signal through a 5" Black and White TV. This achieved another level of video signal loss and made the hard drive speakers usable. The Artist was satisfied. |
