A crystal or crystalline solid is a solid material whose constituent atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid. It is usually a white powder consisting of soft colorless crystals that dissolve easily in water. We used the crystallizing properties of borax to test the potential of making structures, using various threads and meshes.

nozzle collecting sand particles from a point and a second nozzle  depositing them in another point.

Also in a bigger scale it was necessary to simulate the movement of a double nozzle autonomous machine to define its possible trajectory so that

it never steps on what it did. The coordinates of the movement and the deposition points are exported to a txt format available to be used by the

milling machine. The green circles are the piles of sand and the red, the holes (negative) created to the points from which the sand is collected.

Influenced by an autonomous-deposition machine we started speculating about a mechanic fabrication on-site using the site`s material (sand).

The task of the machine is to re-arrange the existing surfaces by collecting from one node and depositing from the other, piling sand. Once the

surface is arranged glue is poured on strategic points of this surface. The choice of the points (coordinates) are yet to be discussed as it is an important

parameter of our fabrication process.

Trying to deal first with the deposition issues we hacked the milling machine (shopbot) to simulate in small scale the movement of an autonomous

machine. We simulated the movement of a double nozzle machine with a processing definition, extracted the movement`s coordinates and sent it to

the shopbot.

We decided to use a color as a source of interaction and real data creating an image of this stimulus on a physical result.

The machine works with 4 main steps: IMPUT_color stimulus,  CAMERA-Screen_to identify the movement, PROCESS the information and RESPONSE on a physical result.

the “light detector” is the outcome of the workshop in digital tectonics  2011 at Iaac . By taking apart a basic printer and reusing its motors in combination with some laser cut MDF parts and a microcontroller we finally succeeded in transforming the old printer into a light mapping device which could both map light intensity and localize areas of equal light intensities in a radial diagram.
