Revision as of 19:48, 13 May 2026
Making techno using naturally grown semiconductors fossicked from mine waste around Cornwall. Also providing workshops for kids (called Organised Atoms).
In an age of harmful technological myths detached from the earth - these sounds are an attempt to reconnect with the dirt.
This site documents research with natural semiconductors and new synth designs, circuits and sounds. The technology used (tickling the surface of crystals with thin 'cat's whisker' wires to create point contacts) comes from the early days of radio, when the newly discovered (and not really understood) properties of certain minerals to have a asymmetric response to electricity (now known as semiconductors) was used to convert radio signals into sound.

10/05/2026: Arsenic Labyrinth & Live at Stones Drones & Noise
Limited Edition Cassette & MP3 release on bandcamp
Side A: arsenic labyrinth: arsenopyrite semiconductor square waves resonant filtered using chalcocite crystals, both fossicked from mine waste dumps at Wheal Prosper, St Hilary, Cornwall. Sequencing, modulation and rhythm sounds using a pair of second hand volca modulars. Circuits adapted for natural semiconductor use from Roland TB-303 style ladder design.
Wheal Prosper was originally part of Marazion Mines, and later (after 1860) Prosper United. From 1832-49 14,600 tons of copper ore were sold, worth £60,000. Minor sales of tin, arsenic and lead ore are also reported. Today (2026) the site is accessible via a public footpath and consists of many overgrown dumps, crisscrossed by tracks with one large area of exposed mine waste. Melanterite is abundant here, and blows about in the wind when you disturb the surface rock.
Side B: live at Stones Drones and Noise Club at Gwithti an Pystri, Falmouth, 28th Febuary 2026. During the performance the following Cornish semiconducting minerals were switched between: Square wave voice: ◇ chalcopyrite and galena from Ale & Cakes Mine, Gwennap, ◇ chalcocite from Penstruthal mine, Lanner, ◇ cassiterite from Unity Wood Mine, Gwennap. Triangle wave voice ◇ chalcocite from Penstruthal mine, Lanner, ◇ arsenopyrite from Penlee beach, Newlyn. Noise voice: ◇ pyrite from Nangiles Mine. Distortion (see circuit diagram) on 4 track ambience: paired chalcopyrite crystals from Ale & Cakes Mine. Includes field recording fragments from Wheal Busy, Chacewater.
Thank you to Jessica Beechey and Steve Patterson for giving the world stones drones and noise, and recording and kindly providing the cassette of this performance.
The circuit board on front cover is the experimental natural semiconductor diode ladder filter used extensively on side a of the recording.

Performance using the Crystal Log Synth at Stones Drones Noise Club, see also Boulderdash Zine
14/12/2025: 220 below adit (techno from mine waste) - album on bandcamp
Tracks made entirely with material (mostly chalcopyrite, pyrite, galena) from Ale & Cakes mine, Gwennap, Cornwall (now United Downs Raceway).
All proceeds will go to the Panzi Foundation, supporting victims of sexual violence in conflict mining areas in the Democratic Republic of Congo, an illegal exploitation that ends in our laptops and mobile phones.
2025- Soundcloud tracks
Test tones and beats, a progression of experiments on soundcloud
06/03/2025 Live at 0v ⏚ zero volts Constant in Brussels
Recording on soundcloud 4 cardboard boxes, an echo pedal, streaming artefacts and the funniest end of performance accidental comedy moment. Part of 0v ⏚ zero volts at Constant, Chaussée de Jette 388 Jetsesteenweg, Brussels. "Two days of return to ground, research of electronic legacies, recognition of mineral ancestors, dissolution of black boxes."
This short streamed performance highlighting the rawest sounds based on the organised atoms circuits was followed by a microscope tour of crystals from various mines around Cornwall.
