Imagining some kind of bio-remediation setup with computer PCB, earth and mycelium. Perhaps as part of the “earth computer”: embedded measurement as device in the soil (writing _from_ the soil), use of electrolysis (a crystal garden), earthboot: booting a laptop directly from soil currents. Powering through earth battery mentioned below.
At the same time literal translation of elements such as display (coil/mirror for telluric currents, or piezoelectrics and laser), memory (earth cores arrayed), CPU (point contact, earth doping - see FET below).
grain mycelium, mixer/blender, straw, plastic trays, earth battery (copper, zinc, other metals?), see DIY FET/transistor, for electrolysis: copper and zinc, larger PSU
thin film transistors ref: http://1010.co.uk/materials.html also http://www.andaquartergetsyoucoffee.com/wp/?page_id=130
perhaps also some integration with earth computer project above: doping the earth/soil, the whitby point-contact transistor; doping melt ores
for early semi-conductors/transistors see: reference
approaches: point contact (germanium, galena-lead sulfide), junction (cuprous oxide), FET/thin film (cadmium chloride)
oscillator setup a la: http://www.sparkbangbuzz.com/els/ntype-nr-el.htm

point contact: phosphor bronze from guitar strings, germanium, galena(lead,sulphur,silver)
cuprous oxide: copper sheet, borax, lye(drain cleaner), silver ink
thin films (sci am): thiourea, cadmium chloride, indium, vinyl cement, silver paste, silicone
thin films/zinc oxide ref: indium replaced with conductive adhesive, zinc nitrate, propanol
Goldschmidt/thermite redox reaction see 'synthetic geologies' on techniquescrushed/powdered ores
thermite reaction - concrete area outdoors, clay pot/similar, iron + aluminium oxides/ores, magnesium powder + ribbon, small amount of barium nitrate,
microwave - diy microkilns (alumina crucibles coated w. cmc/silicon carbide or magnetite, clay pots, alumina/ceramic fibre blankets
furnace - furnace, graphite crucibles, moulds or heavy steel plates
Moissan furnace - alumina bricks, copper sheet electrodes, old arc welder
onion skins, mushroom, samples (10x20mm) immersed 1 hr. and rinsed in distilled water → preparations of 1000/3000/5000 ppm sodium silicate in leachate/contaminated water from recycling experiments left for 24hrs/1week → microscopic photography for comparative rates of deformation/preservation
PH meter, Hcl, flasks
induction coil furnace + conductive work piece + mineral = pyroelectric effect
see: http://en.wikipedia.org/wiki/Masaru_Emoto
eg. investigate use of leachate solutions (question whether water separates acid from its crystal matrix) (nitric -42°C, hydrochloric -46°C, sulphuric -3°C - but depresses when <100%) → microscopy/kirlian imaging experiments
use liquid nitrogen/dry ice (fridge/freezers -18 to -34°C)
JK to bring kit from London - glass plates, clips, transistors, 1x ignition coil, acetates
see: http://xxn.org.uk/doku.php?id=artificial_fulgurites and http://xxn.org.uk/doku.php?id=openlab_fulgurites
one idea is to use new geologies (synthesized computer minerals) (fossilizations of the anthropocene), as crushed (accelerated erosions) substrate for high voltage discharges → fulgurites
mot(s), neon transformer (try arc welder), bucket/box, ignition leads, stick, powedered minerals/silica etc
