1,126 gold contacts. One ordinary beanie.
$5,000. The first 100 ship in March 2027.
Looks like a beanie. Because it is one.
An ordinary acrylic rib-knit beanie goes over everything: the shell, the boards, the hub. Its turned-up cuff holds every contact against the scalp, and it makes the most instrumented thing you own look like a hat.
No gel. No paste. No cap.
1,126 gold-plated pogo pins press through the hair onto the scalp, each with 2 mm of travel. Every tile is small enough that all of its pins reach. Put it on dry, take it off clean.
66 tiles. 9 designs.
Three rings of trapezoids follow the cuff, like the panels of a cap, and a top cut into territories closes it. Together they cover 71.7% of the scalp, and nearly every tile in a ring is the same board. Each one plugs into the next: 16 short chains to the hub.
Gain of 201. 500 times a second. Every channel.
A zero-drift TLV333 amplifier behind every contact, against the reference contact, and a CH32V203 converter for every ten. All 132 converters share one clock and one sync line, so 1,126 channels are sampled together, within 24 ns of each other. One 12-bit step is 4.0 µV at the contact, averaged down to 500 samples a second.
Sees what you see. Hears what you hear.
Five 2-megapixel cameras with 160° lenses, three across the front and two on the back rim. Each has its own microphone and its own Wi-Fi radio. A light comes on whenever a camera's sensor has power.
The hub.
At the back, under the pod: two RP2350s collect the chains, an ESP32-S3 handles Wi-Fi, and USB 2.0 High Speed carries everything to a computer. A 2000 mAh cell sits under the cover. It charges only off the head: plug in a cable and the contacts' supply switches off.
