OpenSCAD BCI Hardware

Parametric 3D models for brain-computer interface and neuromodulation hardware.

Assets Index

Model	File	Purpose
Electrode Holder Mod	`electrode_holder_mod.scad`	Modified EEG electrode holder for dry/wet electrodes
Paste Adapter	`paste_adapter.scad`	Conductive paste application adapter for wet EEG
Headset Hook	`headset_hook.scad`	Mounting hook for BCI headset suspension
C3/C4 Pogo Comb	`c3c4_pogo_comb.scad`	Spring-loaded pogo pin electrode comb for motor cortex (C3/C4 10-20 system)
fNIRS ECU Housing	`ecu_housing_base.stl` + `ecu_housing_lid.stl`	OpenNIRScap electronics enclosure
fNIRS Sensor Capsule	`sensor_capsule.stl`	Light source/detector capsule for fNIRS optodes
Electrode Plate 8-up	`electrode_plate_8up.stl`	8-position electrode array plate
Eurorack Frame	`frame-rail.stl`, `frame-connector.stl`, `frame-stand.stl`	Moduleur eurorack housing for BCI signal chain

Usage

# Render STL from SCAD
openscad -o output.stl -D 'electrode_diameter=10' electrode_holder_mod.scad

# Batch render all SCAD files
for f in *.scad; do openscad -o "${f%.scad}.stl" "$f"; done

Design Constraints

All models parametric (electrode diameter, spacing, head circumference)
Print orientation: flat side down, no supports needed for most parts
Material: PETG recommended for skin contact (autoclavable)
Tolerances: 0.2mm for press-fit, 0.4mm for sliding fit

Integration

Pairs with zig-syrup-bci for signal acquisition firmware
Pairs with opennirscap-build for fNIRS cap assembly
Pairs with cyton-dongle for OpenBCI Cyton/Daisy connection

codex-ocapn-correspondence

plurigrid/asi

Maps the 18 OCapN/CapTP/E-rights patterns reinvented piecemeal across codex-rs to their canonical Spritely/Goblins equivalents and the hermes-* bridge skills that formalize each correspondence. Use when auditing capability architecture in codex-rs, planning a Hoot/Goblins port, or reasoning about which E-rights primitive a codex-rs module implicitly implements.

deep-inference-interleave

plurigrid/asi

Compositional passive inference vs emergent active inference (Hedges Feb 2024) — chain rule, continuations, Siegel-stack cortex mapping, GF(3) triad across monad-bayes / nashator / zig-syrup.

hermes-acp-over-captp

plurigrid/asi

Bridge Hermes' ACP (Agent Client Protocol) transport onto OCapN/CapTP for RPC and Syndicate for the registry/presence layer. The dual (R+D) row of the rubric — invocation/response naturally fits CapTP, while session/agent discovery fits Syndicate dataspace facts. Removes ACP's bespoke wire while keeping its ergonomics.

hermes-approval-as-revocable

plurigrid/asi

Replace Hermes' regex-based dangerous-command detector + per-session approval state with a Goblins revocable forwarder — every authority grant has explicit lifecycle (count-limited, time-limited, user-revocable). Approval becomes a cap operation, not a string-pattern guess.

hermes-cred-as-sturdy

plurigrid/asi

Replace Hermes' multi-credential pool (raw API keys in process memory + file store) with persistent OCapN SturdyRefs wrapped in revocable forwarders. Each provider key becomes an unguessable, revocable cap reference; rotation = swap forwarder; the LLM never sees the bearer string.

hermes-cron-as-dataspace

plurigrid/asi

Replace Hermes' cron scheduler (jobs.py + scheduler.py) with scheduled facts in a Syndicate dataspace. Each scheduled job is an assertion `(scheduled ?id
