This Kit will show you how to build a basic PsychoGalvanometer using a small number of components on a Breadboard.

With the addition of Probes and an Audio Output Jack attached across the speaker, sensors can be placed on the leaves of plants and the modulated square wave data stream can be brought into a computer for processing.

By translating these signals into MIDI, we are able to graph, through sound, a representation of the dynamic changing states within plants.
