BBuild

No hardware exists. This is the specification taking shape.

The Build section is where research turns into constraints: how many contacts, where they can physically go, what the electronics have to do. Every prototype will get its own permanent version page, including the ones that fail.

Early prototypes, when they exist, will be research devices. Not medical products, and not diagnostic tools.

01Why around-ear

DiscretionEar-worn electronics are already socially invisible. A scalp cap never will be, and that alone rules out most daily use.

StabilityThe ear gives mechanical anchoring, which matters because electrode movement is one of the largest artefact sources in wearable recording.

ContinuityA device someone will wear for hours produces a fundamentally different kind of data from one worn for a twenty-minute session.

The costFew contacts, close together, far from most of the cortex. That is the trade being measured in Study 01 rather than assumed away here.

PlannedPlanned

Turn the constraints into a specification: how many contacts, where they can physically sit on an around-ear hook, and what the amplifier and power budget have to be.

Hardware: Not built. Around-ear hook form factor under consideration.
Sensors: Contact count to be set by the sensor-reduction curve from Study 01.
Electronics: Amplifier, ADC, microcontroller and wireless link — not yet specified.
Software: Companion interface, calibration flow and privacy controls — concept stage.
Test results: None. No hardware has been tested.
Limitations: Every dimension on this page is indicative. Nothing here has been fabricated, worn or measured.
Next iteration: Component selection and bench testing of the amplifier path, once the target contact count is known.

03Industrial design

PlannedVersioned CAD and renders, with old versions preserved so this becomes an engineering history rather than a showcase of the latest shape. The earbud geometry on the homepage is an illustration of the constraint, not a design.
