in a very poor condition as a result of disuse and neglect
The digital holocaust has occurred and all electronic devices have ceased to function. The dark Earth opens its sulfide veins allowing for the human extraction of its metallurgic blood. Chalcopyrite, Malachite, and Germanium spew forth, harvested and returned to the alchemists. Divided into occult movements of the future politics of the dark Earth they are crudely processed into communication devices aiding with retro-death-telegraphy and hylozoistic neural computation.
Electricity is reinstated by means of the dark Earth flesh drenched in its acidic mucus. The signal is sent directly to the hylozoistic neural computation unit, a crudely built circuit constructed with Chalcopyrite modelling the Axon hillock area of the human neuron. The signal is now at the level of internal mineral solutions performing ionic transfers causing electrical lightening storms shooting through cells. Axon hillock is firing like a spasmodic machine gun spewing out incandescent howls and screams of white noise automatically reloading the onslaught continues as possession trance is manifest. The Germanium pinned down by sharp copper spikes scratches at the walls between the dark Earth and the afterlife hoping for two-way trans-dimensional communication. Believe you are possessed by a god or deity. Something other has entered you, nonhuman. It is the nonhuman we are now in communion with.
In this workshop we will use a mesh of point contacts connecting to chalcopyrite and iron pyrite to make crude amplifiers out of rocks. When an electric current is sent through the rocks sporadic noise bursts from the speakers. With some fine tuning these rocks begin to behave like microphones, amplifying howling feedback and detecting subtle scratches and disturbances in their surrounding environment. Occasionally the circuit exhibits visual output coinciding with the audible in the form of small sparks and minute explosions occurring where the copper point contacts meet the surface of the rock.

A very crude, home made solar cell using copper and copper oxide. Photons land on the metal plate of the solar cell and this causes electrons to eject. Electrons are able then to pass from the copper oxide to the copper resulting in a fluctuation of energy(?) in the solar cell which can be measured and if connected to an amplifier and loud speakers it can be perceived audibly as a pulse or “bang” of sound. A light signal has been converted to sound and is perceived as a simultaneous and completely synchronised audiovisual signal.
This crude solar cell is based on Nyle Steiner's photocell and Wilhelm Hallwachs (1904) semiconductor-junction solar cell. Hallwachs' experiments laid the foundation for the modern day photoelectric electric cell.
