THE BRAIN-INTERFACE PROJECT
A modular approach to brain-signal acquisition. Thoughtful contact mechanics on the head. Accessible electronics on the body. A signal path you can follow.
Research hardware concept. No assembled performance, clinical benefit or diagnostic capability is established.
Understand the signal.
Respect the uncertainty.Design intentions and planning values.
Not complete-system ratings.
THOUGHT IN EVERY INTERFACE
Small scalp signals deserve deliberate mechanics, a defined reference and a carefully controlled path to the recorder.
The garment baseline uses passive dry-contact modules in a removable helmet liner. Pneumatic preload and individual flexures accommodate fit. A detachable shielded loom runs to a forearm-mounted IronBCI-32 board, keeping acquisition electronics out of the helmet.
THE ARCHITECTURE, OPENED UP
The conventional acquisition baseline stays separate from experimental optical links and other sensing modalities.
Conventional baseline: contact voltage is measured relative to a reference, with a separate bias path as needed. The signal illustration is explanatory; no live or recorded human EEG is displayed.
Sixteen to thirty-two dry contacts sit in removable, pneumatically preloaded cassettes. Helmet structure supplies the reaction force; local flexures accommodate surface variation.
The illustration shows a possible distribution, not a selected medical electrode montage.
MADE CONCRETE
Reference dimensions and proposed interfaces make the concept tangible. Full packaging remains part of the design work.
Micro-bladder target: 1.0–1.5 mm collapsed, 2–3 mm inflated. Compliant flexure: 0.5–1.0 mm. These are analytical packaging targets.
A flat face suits hairless skin; short rounded 2–4 mm petals/pins are explored for hair-bearing scalp. Force, impedance and comfort remain to be characterized.
Estimated protective depth for the approximately 70 × 70 mm board, before a battery allowance. The acquisition module is on the forearm.
OPEN ABOUT WHAT GOES INTO IT
USD component references, historical source snapshots and clearly visible gaps.
One forearm board, enclosure and connectors. Board availability, channel behavior, noise, power and software support are not assumed from a name.
Silver/AgCl contacts, small bladders, flexures, force stops, pressure ports and removable liner interfaces.
Detachable wiring, strain relief, protected connectors and defined signal reference. Shielding is not automatically the reference electrode.
Supply, regulation, restrictors and pressure measurement compatible with contact-force limits.
OPA376 buffers, feedback-controlled LED channels, one 1 mm plastic fiber per channel and remote photodiode receivers. Not added to the conventional baseline.
Additional physiology and magnetic sensing have distinct hardware, noise and interpretation requirements; neither is included in the EEG baseline.
THE QUESTIONS WORTH ASKING
The selected garment baseline is a passive dry-contact helmet liner connected by a detachable shielded loom to an IronBCI-32 acquisition board on the forearm. The board is approximately 70 × 70 mm. This page depicts that architecture, not an imagined standalone wireless headband.
No such capability is established. EEG records small voltage differences influenced by neural activity and many artifacts. Contact quality, movement, muscles, eye motion and the electronics all affect the recording. Diagnostic, cognitive-enhancement and clinical-outcome claims would exceed the evidence.
No. The four-channel analog optical experiment buffers each contact, controls an LED with a local monitor-photodiode servo, carries light through one fiber per channel and recovers it at a remote receiver. It remains a separate experiment with its own calibration and noise questions.
The repository preserves a Rust Muse 2 BLE client, feature extraction, streaming server and WebSocket viewer. That software foundation does not by itself support the proposed IronBCI board or establish a validated closed-loop neurofeedback application.
THOUGHTFULLY DESIGNED. OPENLY EXPLAINED.
