Just the Sensor

Thank you for your support! We'll send you a sensor PCB and parts! Use it in your own projects or as a weird bookmark! We'll provide schematics so you know how to connect it, too!



Your very own HEG biofeedback kit! Assembly required, including soldering, uploading the core program to the ESP32, and attaching it to the headband. Comes with our custom receiver and flexible sensor PCBs, an ADS1115, wire and connectors, resistors, 6 ft (2 m) micro-USB cord, some lead-free solder, and a headband. Available with either a WeMos Lolin32 V1.0.0 or an Adafruit Huzzah32 Feather.


Assembled HEG

Start training your brain as soon as your HEG arrives! These are hand-assembled and tested by our team to run out-of-the box. Available with either the WeMos Lolin32 V1.0.0 or the Adafruit Huzzah32 Feather.



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