Digital signal processing utilities as RxJS operators for working with EEG data in Node and the Browser
In my original "Brain to the Cloud" project, I used a "vintage" EEG headset called a MindFlex to capture my brain readings. It worked fairly well, but required me to "hack" the device by adding an ESP-12 microcontroller in order to pull the readings off of the device and send them to the cloud. This time I reached for something slightly newer - and something that I could use with no modifications. After a bit of research, I settled on the Muse S Headband. Thankfully, there is a really awesome open-source library called muse-js which let me to access the brain readings directly in a web browser with Web Bluetooth (in supported browsers, of course).
In this post, we looked at how I created a React application to live stream my brain data with Amazon IVS. If you'd like to learn more about Amazon IVS, please check out the series Getting Started with Amazon Interactive Video Service here on dev.to. If you're interested in trying out the application or just checking out the full source for the application, check it out on GitHub. Your comments, questions and feedback is always welcome, so leave a comment here or connect with me on Twitter
As I mentioned above, I used the muse-js library, which provides the ability to connect to the headband and pull the raw data. However, muse-js does not calculate the absolute band powers for the EEG data. For this, I needed to reach for another library: eeg-pipes.
