PROJECT TITLE: THE PNEUMALITH


Subtitle: The Carbon-Lattice Archive (CLA) — A Bio-Lithic Somatic Interface


1. EXECUTIVE SUMMARY


The Obsidian Anchor challenges the fundamental dichotomy of hardware design: the separation between the "grown" (biological, chaotic) and the "built" (silicon, ordered).

This project proposes the creation of a "Bio-Lithic Processor"—a functional electronic interface grown from living mycelium, fossilized into conductive Glassy Carbon, and utilized as a somatic instrument.

By subjecting a living fungal network to specific sonic environments and subsequently processing it through inert-atmosphere pyrolysis, we aim to transmute ephemeral biological behavior into a permanent, geological artifact. The result is a "Functional Fossil"—a stone that remembers it was once alive, allowing users to interact with sound through the microscopic expansion of their breath.


2. PROJECT NARRATIVE: THE ALCHEMY OF TRANSMUTATION


Current neuromorphic engineering attempts to mimic biological brains using silicon. This project takes the inverse approach: it uses a biological brain (mycelium) to template a conductive circuit, then fossilizes that thought process into stone.

A. The Ghost in the Machine (Thigmomorphogenesis)

The process begins with life. A colony of Ganoderma mycelium is grown in a mold. During this phase, the colony is subjected to a specific sonic regimen ("The Residency"). Fungi respond to vibration by strengthening their cell walls and altering their hyphal density. The music played during this phase literally shapes the physical microstructure of the network.

B. The Fire (Pyrolysis)

We then subject this "educated" block to intense heat ($900^\circ\text{C}$) in an oxygen-starved nitrogen atmosphere. Combustion cannot occur. Instead, the material undergoes thermochemical decomposition. The organic volatiles boil off, and the carbon backbone collapses but retains the exact geometry of the hyphal network. We are not burning the mushroom; we are turning it into a Reticulated Vitreous Carbon Foam.

C. The Stone (The Interface)

The final object is impregnated with optical resin and polished to a black mirror finish. It connects to the user not via a screen, but via Bone Conduction. High-torque transducers inside the stone vibrate the user's skeletal system directly (C7-T12 vertebrae). The user does not hear the sound; they feel the stone singing inside their own spine.


3. TECHNICAL METHODOLOGY: THE "GARAGE R&D" PROTOCOL


This project rejects the necessity of the institutional laboratory. It relies on a "High-Craft / Low-Tech" approach, utilizing accessible tools to achieve advanced material science results.

  1. Carbonization: We will utilize a programmable Heat Treat Oven (commonly used in knifemaking) paired with a custom-fabricated steel retort and nitrogen purge system. This allows for the precise "Ramp and Hold" thermal curves required to carbonize the block without cracking it.

  2. Quantum Tunneling: The resulting carbon matrix functions as a piezoresistive sensor. The block is a percolation network that is just barely conductive. When the user inhales, their thoracic spine compresses the block by micrometers. This forces the carbon grains closer together, allowing electrons to "tunnel" through the gaps.

  3. Signal Processing: A Teensy 4.1 microcontroller reads these massive drops in resistance and translates them into Generative Audio, which is fed back into the user's body.


4. BUDGET NARRATIVE


To achieve this transmutation, the project requires specific thermal equipment and, crucially, dedicated research hours. This process involves complex thermal cycles that last 24-48 hours and sensitive biological cultivation. It cannot be done "in the margins" of a day job; it requires immersion.

The budget is structured to support a 3-month intensive R&D phase.


A. Research Fellowship / Artist Stipend: $8,000


  • Justification: Funding to cover the artist's living expenses and labor for a 3-month immersion period.

  • Scope of Work: Daily monitoring of mycelial growth, programming and safety monitoring of thermal pyrolysis cycles (which often run overnight), firmware coding, and physical fabrication.

  • Rate: Calculated at approx. $33/hr for 20 hours/week $\times$ 12 weeks.


B. Technical Apparatus (Permanent Equipment): $1,400


  • Evenheat/Paragon Heat Treat Oven (24" Depth): $1,100.

  • Detail: Provides digital ramp-hold control for carbonization. Unlike industrial ceramic kilns, this runs on residential power and fits a workshop bench.

  • Nitrogen Atmosphere Control: $300.

  • Detail: Rental of Nitrogen tanks, regulators, and raw steel for fabricating the airtight retort vessel.


C. Materials & Electronics (Consumables): $1,000


  • Somatic Hardware: $600.

  • Detail: Teensy 4.1 Microcontroller, 16-bit ADCs (for high-precision resistance reading), High-Torque Transducers, and Stainless Steel "Medusa" cabling.

  • Fabrication Materials: $400.

  • Detail: Mycelium spawn, substrates, optical-grade epoxy resin, and diamond polishing abrasives.


D. Documentation: $600


  • Detail: High-quality audio/video recording of the "First Breath" (system activation) to serve as the final deliverable.

TOTAL GRANT REQUEST: $11,000



5. IMPACT STATEMENT


The Pneumalith is a rejection of planned obsolescence. It proposes a future where our electronics are geologically stable rather than disposable. By funding this research, you are supporting an independent investigation into Neo-Lithic Cybernetics—a new class of objects that are high-tech in function, biological in origin, and geological in lifespan. We are moving beyond the Silicon Age and into the era of Intelligent Stone.
