A visualizer boilerplate for the NeuroSky brain scanner and Node.js

#Node ThinkGear Visualizer v0.1

##Installation

First, you'll need one of these:

Then install Node.js and install some packages (these may already be installed when you download this repo. not sure.)

$ npm install express
$ npm install socket.io@1
$ npm install node-thinkgear

then start the app by running

$ node app.js

You should see a message that says, "listening on port 3000." Then open a web browser and point it to http://localhost:3000. In most browsers, you do have to include the "http" part.
