Instruments for technocosmic germination

The  experiment (biome) that is being performed questions whether the germination rate of seeds is affected by frequencies.  It stimulates intra-actions within the universe of seeds, soil, birds, air, hardware, people and basic natural elements. It declares the Electromagnetic field as a critical natural resource. 

SOUND 
Sound is vibration that travels through air. Without those molecules of nitrogen, oxygen, carbon dioxide, etc., there would be no sound: A  telephone ringing in outer space would go unanswered even if an  astronaut happened to be floating by, because no one could hear it.  Sound vibrations come in a wide range of frequencies. The audio  range—which extends up to about 20,000 vibrations per second (cycles per  second or CPS)—includes those frequencies that people can hear. When the frequency of a sound extends beyond our normal hearing limit, we have ultrasound. 

EMF: Read Electromagnetic field as a natural rescource


A nano smano
is a device that oscillates by a resistive gas sensor.

A chaospoti 
is a device which creates chaos by using the bodies resonance

A geophone   is a device that converts ground movement (velocity) into voltage. The  deviation of this measured voltage is sonified by anoscillator (Axoloti)

A mindsynthesis
is a device that converts brain activity into frequencies, the   sonification is an auditive interpretation of ? , ?, ?, ?,   ? values  which are emitted

There is a correlation between between earth frequency and brain rhythms. Tthe earth vibration could be measured the clearlest  in nature and on  the ocean . 
The best frequencies for the human body are earth's natural  frequencies. They are the most beneficial and actually the only  absorbed and useful pulsating magnetic frequencies for the human   organism. Predominate earth based resonant frequencies are 7.83 Hz  and 11.75 Hz (or 11.79 HZ) and their higher harmonics. 7.83  Hz (Schumann generators) in the space suits and space stations to prevent  serious illness. The human brain state frequencies correspond to these frequencies cells respond to roughly 3-25 Hz .

A 50 Hz horn is a device that  driven by a flat circular steel diaphragm, which repeatedly interrupts the current to an electromagnet.
50 Hz is a radio frequency in the SLF band used by submarine communication systems.
Seed   treatment with MF 30 mT, 50 Hz, 30 s did not stimulate seed germination  and growth processes in the seedlings, but resulted in an  increase of plant antioxidant potential under soil flooding.

A pedal powered butterfly is a device which rectifies alternate current into direct to activate a music toy melody
