###Software Requirements

* Erlang R15B+
* MySQL Server
* Thinkgear Connector (comes with installation media)
* An active internet connection as Google Graph API is used for the charting.

###Current development status

Code should be considered a proof of concept.

###Usage

Create a new MySQL database eg. `erltricity` and run the table creation statements from `table.sql`

Copy the database.config example file and adapt it to your MySQL Server needs:

`cp config/database.config.example config/database.config`

Start up an Erlang shell:

`rebar get-deps compile && ./shell.sh`

Now is a good time to turn on your Mindwave headset.

Inside Erlang shell:

`application:start(erltricity).`

And point your browser to [http://localhost:8000/chart](http://localhost:8000/chart) to see the recorded EEG signals. Manual refreshing is required in this version.

###Example Chart

With a proper signal, the chart should look something like this:
