[edit] Open-source projects
The OpenEEG project offers individuals a way to build their own EEG device. The OpenEEG project estimates that building your own EEG costs $200 and takes a few weekends. The OpenEEG product was the earliest method for individuals who wanted an inexpensive EEG for personal use; today EEG enthusiasts are cannibalizing toys like the Mindflex, Force Trainer, and MindWave to build less expensive more reliable personalized EEG devices.[25][26]
Emokit is an open-source Python library for reading out sensor data from the EPOC (Emotiv Systems) by Cody Brocious. It was built by reverse-engineering the encrypted protocol.[27] Emokit has been deprecated in favour of emokit.[28]
In 2011 Make Magazine published an article on hacking NeuroSky headsets
EEGLAB is a GNU Matlab toolbox for processing data from electroencephalography (EEG), can be used as neurofeedback tool.
OpenVibe is a LGPL software platform (C++) to design, test and use BCI.[29] The software comes with an acquisition server that is currently compatible with many EEG device including Neurosky Mindset, Emotiv EPOC (Research Edition or above) and OpenEEG. The software is developed at INRIA.
Several open-source computer programs are also available from EPFL's CNBI project.[30][31]
[edit] Technology
All of the devices listed use electroencephalography except the Neural Impulse Actuator which only uses electromyography. Some use both electroencephalography and electromyography, such as the MindWave, EPOC, and MindSet.
