Specs.
Every number in plain words, with the engineering beside it.
- Battery
About 2 hours with every camera on. About 3 hours with them off.
4,000 mAh, 14.8 Wh. 6.94 W with every camera streaming. - Charging
About 2.5 hours by USB-C, off your head.
USB-C, 2 A. The contacts' supply is held off while a cable is plugged in: it charges only off the head. - Weight
About 920 g, all in.
Cap, boards, contacts, hub, cameras and battery. - Sizes
S, M and L, by head circumference.
S under 56 cm, M 56–58.4 cm, L 58.4 cm and over. To measure, run a soft tape just above your eyebrows and around the back of your head. - Brain
1,118 points across your whole scalp, 500 samples per second.
EEG: 1,118 dry contacts, 500 samples per second per channel, sampled together. - Sight and sound
Five cameras round the brim. A microphone beside each.
Video: five 2-megapixel cameras with 160° lenses, 800 × 600 at 15 frames a second. Sound: a microphone beside each camera, 16 kHz, 16-bit. - Your data
On your computer. Every file encrypted. Nothing sent to us. Export or erase it all in one step.
Over Wi-Fi the cap talks only to a computer paired with it over its USB cable, and everything between them is encrypted and authenticated (Noise, X25519). The app encrypts every file it records on your computer (AES-256-GCM), its key in the computer's keychain where it has one. - Works with
The desktop app on Linux and Windows, or Chrome and Edge. macOS to follow. Pair once by USB-C, then record over Wi-Fi. Your phone follows along through your computer.
2.4 GHz Wi-Fi, the cap's one radio; the cameras have none. USB-C, USB 2.0 High Speed (480 Mb/s), for pairing, updates and the full video. - Recording light
A red light on every camera, on whenever it can record. No software can switch it off.
A red light on each camera, powered from the camera's own supply, so it is on whenever the camera or its microphone has power; the firmware can add light but cannot turn it off. - Contacts
Gold spring pins, 8.5–11.8 g each, through your hair. No gel. No paste.
113 N across the whole head. About 2 mm of travel. - The cap
Soft stretch knit, no hard shell. Each board tilts on its own button to sit flat.
To wash, unclip the electronics, hand-wash the cap at 30 °C and dry it flat. - Safety
Any single fault is limited to microamps through a contact. The antenna sits at least 27 mm from your scalp. Not a medical device.
At most 33 µA through any one contact with one part failed. The limit is taken from IEC 60601-1, a medical standard used here only as a reference: exocortex is not certified to it. - Certification
FCC authorization comes before the first unit ships.
This device has not been authorized as required by the rules of the Federal Communications Commission. It is not, and may not be, sold or leased, or offered for sale or lease, until authorization is obtained. The plan: FCC Part 15 Subpart B for the electronics, an FCC ID for the one 2.4 GHz transmitter, the RF exposure exemption, and the battery packs' IEC 62133-2 and UN 38.3 reports from their maker. - Price
$5,000 + tax, free US shipping. $250 refundable deposit. The first 100 ship by December 2027.
Outside the US, shipping and duties show at checkout. The balance is charged only when your unit is ready and you approve the final price.
