Simple graphs for Neurosky Mindwave Mobile
You can use this with a neurosky headset.
I don't think it really improves upon the bundled app too much, but eventually maybe I will link it with other things and improve the UI. This one is open-source and easy to modify, though!
If you aren't interested in building it yourself, try a release
If you'd like to use the library I used here, in nodejs, in your own thing, check out mindwave.
Install the build dependencies with npm install. You can build runtimes with npm run build, and you can test (run on current platform) with npm start.
