Summary of main hardware components

To record EEG data we will use the OpenBCI project’s 8bit board The OpenBCI board comes with a Bluetooth dongle based on the RFduino. Processing of EEG data will be done using the Raspberry Pi B+ The Raspberry Pi B+ will be connected to an HDMI monitor for the GUI as well a mini MIDI controller (e.g. the Novation […]

For the purpose of developing the Python code, I’ve installed Virtual Box, on which I installed CentOS 6.6. I had an impossible time getting the Guest Additions installed, which are needed to be able to map USB ports, until I found a site with Virtual Box images with Guest Additions pre-installed. I then downloaded the […]

Programming platforms considerations

We plan to develop the final EEG-synth user-interface in Python for several reasons: It can be run on the Raspberry Pi (on the Debian-based Rasbian operating system), with is our target system for the final ‘product’ It has a great number of libraries for numerical calculations, serial and MIDI interfacing, and graphical display It has […]

Study material

Think Python, How to Think Like a Computer Scientist by Brian Downey Synthesizer Cookbook by Fred Welsh Make: Analog Synthesizers by Ray Wilson Thomas pointed out these fantastic posters with synthesizer basics To get some (virtual) experience with modular synths I installed LiveProfessor, a free VST host. In this, I installed the Fre(a)koscope VTS plugin, […]

Github for sharing code

I registered on GitHub, and created a repository to share our developing code. For now I just tested it by uploading the lastest OpenBCI python code. You can find the repository here.

MIDI controllers!

Robert had the great idea that, at least for now, we don’t have to solder our own control panel, but could start using a MIDI controller board. Brilliant! Today friend and collaborator Tomas Nordmark has very kindly borrowed me two FaderFox MIDI controllers! So stoked! I’ve learned that MIDI is not only a matter of […]

Sonification of MEG brain waves when falling asleep

MEG activity of Jean Louis was recorded while he was trying to fall asleep. For this purpose he was sleep deprived the previous night. I then took a ~24 minute interval (starting at about 25 minutes after start) of recording and tried to sonify his oscillatory brain patterns. In other words, find a way to […]
