A Node.js client library for the ThinkGear Socket Protocol from NeuroSky

#node-neurosky

Client library for the ThinkGear Socket Protocol from NeuroSky.

###You'll need one of these:

###Usage

Install with NPM:

$ npm install node-neurosky

Include the module:

var neurosky = require('node-neurosky');

Create a client instance:

var client = neurosky.createClient({
	appName: 'My Great Application',
	appKey: '1234567890abcdef...'
});

Add a listener for incoming data:

client.on('data',function(data){

	// magical and wonderful things

});

Connect to the headset:

client.connect();

All of this is in the example/app.js file too.

###Data

The output objects look like this:

{
	eSense: {
		attention: 53,
		meditation: 47
	},
	eegPower: {
		delta: 416474,
		theta: 33592,
		lowAlpha: 3877,
		highAlpha: 3142,
		lowBeta: 1569,
		highBeta: 3125,
		lowGamma: 3521,
		highGamma: 1451
	},
	poorSignalLevel: 0
}

With the occasional { blinkStrength: 55 } when you blink.

###TO DO

• Some tests
• A more thorough example
• Deal with raw output
• Make different types of device signal emit different events

node-neurosky's Issues

Only receiving 1 sample per second

For some reason I am only receiving one sample per second instead of the 512 samples per second the device supports.

Connection Refused

Hi! I'm setting up a Mindwave Mobile on Ubuntu. I have paired the headset with the computer.
When I run the example:

node app.js

I receive this error:

events.js:85
      throw er; // Unhandled 'error' event
            ^
Error: connect ECONNREFUSED
    at exports._errnoException (util.js:742:11)
    at Object.afterConnect [as oncomplete] (net.js:989:19)

Any idea where this is slipping up?
Thanks - Robert

Heroku hosting

If i host the app on heroku will this work and receive data from client ?
