FINAL PROJECT: ELECTRIC PUDICA (IN PROCESS)

I. Circuit Overview

Inspired by the smooth-organic movement of the Sleepy Plant (Mimosa pudica) this circuit wants to experiment with different methods of locomotion, testing the posibilites of the nickel - titanium wire alloy.

ASSIGNMENT 2 : THE EXPERIMENTAL RESISTANCE

I. Description

All the objects around us have its own amount of electric conductivity, some of then let the electricity runs wild and other just make it slow. This exercise is an attempt to control the flow of electric current, and show in a tangible way the electric current activity.

Using colored water with a dilution of different conductive materials like salt, soap and vinegar, this circuit makes different noises when the resistance of the piece of paper decreases due the amount of conductive solution in it. The result is a visual color mixing game that plays various sounds according with the ingredient diluted in the colored solution.

ASSIGNMENT 1 : THE IMPROBABLE SWITCH

I. Description

This exercise experiments with the different ways to close a circuit, any material could be a switch with the right construction with more visually interesting results than the black boxes in our daily electronic objects. In this case, a candle is used to warm the air around a metallic spiral and produce movement. When the spiral moves, it opens and closes the circuit, touching aluminum leafs installed inside of the small greenhouse. When the switch is on the little flag in the motor moves and the lights turn on.
