The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University. Sagan and his associates assembled 116 images and a variety of natural sounds, such as those made by surf, wind, thunder and animals (including the songs of birds and whales). To this they added musical selections from different cultures and eras, spoken greetings in fifty-six languages (55 ancient and modern languages, plus Esperanto), and printed messages from President Jimmy Carter and U.N. Secretary-General Kurt Waldheim.
The collection of images includes many photographs and diagrams both in black and white and color. The first images are of scientific interest, showing mathematical and physical quantities, the solar system and its planets, DNA, and human anatomy and reproduction. Care was taken to include not only pictures of humanity, but also some of animals, insects, plants and landscapes. Images of humanity depict a broad range of cultures. These images show food, architecture, and humans in portraits as well as going about their day to day lives. Many pictures are annotated with one or more indications of scales of time, size, or mass. Some images contain indications of chemical composition. All measures used on the pictures are defined in the first few images using physical references that are likely to be consistent anywhere in the universe. The musical selection is also varied, featuring artists such as Beethoven, Guan Pinghu, Mozart, Stravinsky, Blind Willie Johnson, Chuck Berry and Kesarbai Kerkar.
The pulsar map and hydrogen molecule diagram are shared in common with the Pioneer plaque. The 116 images are encoded in analogue form and composed of 512 vertical lines. The remainder of the record is audio, designed to be played at 16⅔ revolutions per minute.
Added new files to olds , for better letter definition and mounting holes.
For better results in plastic print , i recomend slice to 0,1 mm
and outline / perimeters shells = 1
Thanks by the feedback.
UPDATED 19/10/2017 :
Added Sound_disc.stl and Sound_letters.stl for print in two colors . if somebody wants.
The high of the Sound_disc = 1 mm.
Not printed yet , provide the *.x3g files for Sailfish firmware flavour and gcode.
In plastic print optimal results will be obtain if adjust your slicer to 0,1 mm
and outline / perimeter shells =1.
