"Translation Device" for Aristotle´s Jungle sound installation. It consists of a hacked DIY Midi Sprout that is connected to an 8 channel electric Relay board, the Midi Sprout in addition to producing midi notes, now it can also control up to 8 electrical devices, which in this case were electric fans.

DIY MIDI SPROUT:

The sensors are “psycho galvanometers” which graph changes in galvanic response (electrical “skin” conductance/resistance) by producing a square wave of variable frequency and pulse width. Built from a 555 timer IC and a handful of electronic components, each sensor is attached to a leaf on a particular plant using an electrode of silver wire and conductive gel. The vital data of the plant is translated into MIDI notes, this device is connected to a sound generator such as a synthesizer, sampler or computer with MIDI input, to hear the musical notes or concrete sound.

DIY BIODATA SONIFICATION V.02
By measuring microcurrent fluctuations occurring across the surface of a plant’s leaf, this Biodata Sonification device generates MIDI notes when a change in conductivity is detected, allowing a user to listen into the invisible biological processes occurring within plants. This new version features a button and knob that control the Menu with variables of Threshold (at which the device detects changes and fluctuations in conductivity), Note Scale selector (indian, major, diatonic, minor, chromatic), MIDI Channel selection and led brightness.
