Copper

The open circuits of the earth pre-date those closed metallic structures of wire, metals, resistors, capacitors and signal. [Parikka] Signal is, of course, naturally in and of the Earth and the approach of psychogeophysics embraces this earth signal (Earth Sound Earth Signal – Douglas Kahn) to open back up the connection between us and earth. This has been occurring in the field of sonic arts since mid-twentieth century – exploring materials and their sonic properties / acoustics as well as the wider fields of electromagnetism. The South West has a history of extracting the metals of the earth – the soil is electromagnetically rich with copper – ripe for earth circuit practices. Inspired by Martin Howse’s Earth Computing – the copper in the soil investigated through probing for potential sonic interference. Need to re-read Graham Harwood’s short text, along with Raqs Collective, ‘Aluminium’ [2008]. The earth has the signal and dirt (dust) and decay and life for developing next stages of practical work. Copper is essential for the creation of D.I.Y solar cells for light measurement and modulated signal reception – the earth measures. The work begins to move to acknowledge the anthropocene in a direct way. METALLURGY.

Springs and Coils

Springs and coils. The alteration from a single line of material with turns and twists and repetitions of those enables that material to now enter the electromagnetic sphere. A coil of wire now becomes an antenna for mini fm broadcast – to send signal over a small area to a receiver. A coil of wire becomes a pick-up of electromagnetic signals enabling the building of particular ‘sniffing’ devices – listen to your mobile phone or laptops internal processors working.
