# Project: Neurosky Mindstream - System tray app to stream EEG data

[Overview]

Mindstream is a simple java-based system tray app that streams EEG brainwave data from NeuroSky
devices (MindWave,MindSet). The app interfaces to NeuroSky devices using the ThinkGear Socket
protocol (connecting on localhost:13854), retrieves data in JSON Format, and can “stream” to
other applications. Mindstream can save the following data:

* Focus levels
– attention
– meditation
* EEG values
– delta
– theta
– lowAlpha
– highAlpha
– lowBeta
– highBeta
– lowGamma
– highGamma
* Headset signal strength
– poorSignalLevel

Streaming functions will include:

* Saving EEG data to a CSV File
* Listen on a socket and replay data from localhost:13854
– allowing other applications to connect
* Broadcast to a URL – supporting POST/M-POST and streaming real-time data
– future use? Processing Javascript version of the Neurosky BrainWave Visualizer

[Installation]

Currently there is no installer. You can download the source and/or binary distribution:
the primary executable (mindstream.jar) is located in the dist directory. There are
helper scripts to execute loading the app (mindstream.sh for Linux/Mac and mindstream.bat
for Windows). Both scripts simply execute ( java -Djava.ext.dirs=lib -jar dist/mindstream.jar).

[Current Status]

– Alpha state
– Streaming only supports writing to a CSV file
– Tested on Linux and Windows with Java 1.6 and the MindWave headset

[Change Log]

– 07/24/11 – Initial release
– 12/04/11 – Fixed issue reported with saving CSV file (Thanks to Pei Yin) and added some exception handling messages
– 07/07/12 – Added bug fixes from jomack and added additional error checking for issues on other platforms (e.g. Win7)
