BrainBay and OpenBCI tutorial

These pages show a couple of simple BrainBay 'design' (circuit wiring) diagrams, as examples of use with OpenBCI. The two examples are in sub-pages nested below this main page; links at the bottom of this page.

• The first example shows verification of your sensor connections and ability to register alpha with eyes closed -- via a spectrogram.

• The second example is of a simple neurofeedback session for training to increase alpha via audio feedback rewards.

Both examples show you what the designs are doing inside so you can get a feel of how to wire up more of your own design circuits. If you want to simply jump ahead to the neurofeedback example, please read through the first example section to start, as it contains some tips on operating BrainBay.

BrainBay is an open source VPL Visual Programming Language for rapid prototyping of EEG digital signal processing steps (or data flows.) BrainBay is distributed as a Windows installer, but can also run on Macintosh using VirtualBox (free VMs) or Wine. See this related page on the OpenBCI forum. The BrainBay installer is here. User manuals here.

If you have a previous BrainBay version installed that does not support OpenBCI, you do not need to uninstall before installing the new version. You can just run the new installer. If you do use the Uninstaller, be cautious, as it will also uninstall any additions or changes you may have made in your CONFIGURATIONS (.con files) folder. The new Uninstaller dialog box warns of this.
