====Lab notes from "silent dialogues" ====
part of [[borrowed scenery]] experiments in [[plant communication]]

=== 20121016 ===
  * setup & testing of equipment
  * potential amplifier for magnetic coils ->  (c  r a x c.x. xx nk .x)
  * microscopy
  * watered plants
  * notes for [[what a plant knows]]
  * earthboot device -> [[kokedama]] test

project notes (MH): 

  * bioluminscent communication vector: dark goggles with mycelium contained, some way of amplifying photon events
  * earth/plant/fungi resistance, impedance or potential measurement: differential amp(ad620,ca3140), ad5933 with usb, bridge and transistor. electrodes/plant connection? (we also have 1x geophys earth measure device and one generic diff amp(test with plants))

mention in one paper of thin silver wire attached with a glue of honey/potassium chloride mix. also nik mentioned action potential measurement techniques.

  * plant consciousness interface (coil/amp of which measured signals?)

"Two differential amplifiers (AD620 measuring plant microvoltage fluctuations) - where on the plant? Also with GND reference a la EEG, further amplified by IRF640 driving coils placed experimentally on occipital lobes. [An alternative would entail microvoltages driving (adjustable) VCO before coils.]"

simplest magnetic coil amp for interface tested (arriving at 1k series resistor with 15v supply giving around 10-20 milligauss at 3cm distance in parallel) will probably use 9v battery but remains approx same region...

potential sources for amplification: earthboot (but then we have computer), differential amp (ad620-TODO or ca3140), resistance bridge with transistor), also VCO of any...

  * sonification (analogue VCO (741) or simple software)


=== 20121017 ===

  * some notes on action potential (AP) and variation potential (VP) measurement (see [[plant_perception|Plant Perception]])
  * construction of dual coil amplifier and headband (anticipating testing with 2 low frequency signals generated by software)
  * discussion of potential signals for dual coil amplifier (low frequency chaotic modulations 5-10Hz as suggested by close reading of: http://www.mindspring.com/~txporter/persemf.htm
  * two trials of plant consciousness interface with computer (puredata) generated signal. In both cases the means of generation of the signal was identical (white noise modulating sine wave of 8 Hz), and the same signal was applied to both coils. the first trial (MH) with coils attached in proximity to occipital lobes, the second trial (NG) with coils close to temporal lobes. in both cases, no effects could be discerned other than those attributable to concentrated self observation. 
  * NG suggests further trials with improved signal generation: randomly shifting frequency of carrier within parameters alongside noise modulation so we have a differing signal applied to each coil. patch modified for this purpose. 

=== 20121018 ===
  * further tests of modulated noise source to drive each coil separately. initial tests produced slight, somewhat uncomfortable conditions in subject (e.g. "like a toothache, but lower")
  * surface elctrodes for measuring signal propogation in trees. copper wire, gold coated thread, ultrasound transmission gel. mounted at sequent petioles.
  * recording of signals - differential amplification, 1x, 50x. credible results, quite noisy, electrode problems, change in either contact or electrochemical contact. strange enveloping observed. observed ~10 min signals may be VP propagation or experimental error.
  * kernel panic
  * searching for snorkel

=== 20121019 ===
  * goggles to contain [[bioluminescent fungi]] (mycellial photon exchange instrument - [[MPEIR]]) -> optical communication 
  * metaphase typewriter (c.f. [[Nick Herbert]]), primed with "The Power of Movement in Plants" by Charles Darwin -> noise -> statistical proto-meaning
  * field expedition -> 2x 10min experiemtns with earthboot driving coils. mycelial plugs in various stumps (e.g. http://borrowed-scenery.com/zizim/reports/view/164)
  * fermented plant products
  * series of 20min session w. [[MPEIR]] and coils using ferns as signal source (short interviews recorded by MH and SJ)
