01ILLUMINATE
Light the details.
Two 850 nm infrared LEDs provide illumination. A transistor lets the ESP32-S3 switch them together.
A little board.
More expression.
Your expressions belong in VR, too. Facemo Tracker is an experimental camera board exploring a more expressive way to show up.

01 / THE IDEA
From the real you.
To the virtual you.
A small camera, a little infrared light, and a microcontroller. The goal is to capture facial movement and make it useful for expressive avatars in experiences like VRChat.
02CAPTURE
See the movement.
A compatible camera connects through a 24-pin ribbon connector. The ESP32-S3 controls the sensor and receives its image data.
03EXPRESS · PLANNED
Bring your avatar to life.
The intended next step: firmware sends images to Babble on a host, where facial tracking can bring an avatar’s expressions to life.
Hardware is taking shape. Babble integration is planned; firmware and end-to-end validation are still to come.

03 / DEVELOPMENT JOURNAL
Every revision.
A little closer.
From the first sample to the next idea.
Here’s where the
project stands.
-
DESIGN COMPLETE
Alpha, the first revision.
The first board design was completed and sent for fabrication.
-
ISSUE FOUND
Alpha validation and findings.
Alpha samples arrived from the factory. A design error was found, and the board did not work as expected.
-
SAMPLE IN TRANSIT
Luna, two-layer preview.
Design completed. Samples are on the way; hardware verification comes next. This is the board shown above.
-
IN PROGRESSDESIGNING
Luna, four-layer design.
The four-layer version is still being designed.
-
AHEADPLANNED
The rest of the system.
Onboard firmware, the 3D enclosure, and Babble integration are still to be developed.
04 / FOLLOW ALONG
Built with curiosity.
Shared for you to explore.
Look through the design, read how it works, or bring an idea to the project. Tracking is planned with Babble . Luna is still an experiment. You’re early.
