We also wanted to show off some of our software progress this week. Check out our Chrome-based Progressive Web App: Brains@Play, and our latest little project: the Sensorium:

MAX86141 FNIRS Breakout Board

Get the breakout board for the MAX86141 FNIRS sensor, which doubles as a foldable pulse ox. The sensor requires a SPI interface and 3.3V-5V power from a microcontroller. Comes with male and female pin headers and a free Arduino library.


Mounted FNIRS sensor with headband

Get the new low cost HEG headset with the MAX86141 sensor and ESP32 microcontroller, mounted in a handmade wire and fabric headset. The biofeedback software is free and will be receiving feature support for the foreseeable future. Battery not included.



We are a ragtag team of engineers and optimists trying to make a difference in this cold, dark place called Alaska.
