JavaScript

Python and Node.js with OpenBCI

open_bci_v3.py manages the connection between the OpenBCI board and Python
udp_server.py exposes the data over UDP
socket_server.js a Node.js server that retransmits the data over a Web Socket
htdocs/index.html a hack to display data using D3.js

Running the Server

Run npm install to make sure you have the dependencies
Plugin the OpenBCI V3 Dongle and turn on the Board
Run python scripts from (https://github.com/OpenBCI/OpenBCI_Python):

python user.py -p "<serial port>" --add udp_server 127.0.0.1 8888 --add print

Modify settings according to desired behaviour. See OpenBCI_Python README
Start UDP server --> /start
Run node socket_server.js
Visit http://127.0.0.1:8880 to see your brain waves

Optionally

Use python udp_client.py --json from the scripts folder to verify data is coming through
Use python socket_client.py from the scripts folder to view the Web Socket data coming back into Python (requires socketio-client)
