SKIP is a reactive installation
showing a Technics SL1200 turntable equipped with two high performances
white LEDs in place of the stylus. The lights are modulated by four
sine waves (at 0.4Hz, 4Hz, 40Hz and 400Hz).
A 12” mirror disc rotating on the turntable reflects the modulated
light.
Movements near the turntable and vibrations in the floor are sensed
by the installation and cause the lights to skip in their sequences. |

The 12" mirror disc. |
The stylus head with the two high performance
white LEDs mounted. |

The BX24 microprocessor is used to calculating
the level of vibrations and for controlling the LEDs. |
Vibrations in the floor are picked up
using a 10" loudspeaker as a highly sensitive low-frequency microphone.
The green box is a preamplificer used to match the input level of
the BX24.. |
