The MuLES (MuSAE Lab EEG Server) open source software codes are finally up on GitHub. Its an EEG acquisition and streaming server that aims at creating a standard interface for portable EEG headsets, in order to accelerate the development of brain-computer interfaces (BCIs) and of general EEG use in novel contexts. Codes can be found here. This version is compatible with Interaxon Muse, Emotiv EEG, Neuroelectrics Enobio and OpenBCI devices. We welcome your feedback! Thanks to Ana Tavera Mendoza for making the logo and MuSAE Lab members Raymundo Cassani and Hubert Banville for preparing the codes.
