Did we mention already that we have been awarded a grant from Innovativ Kultur?
This week I co-organized a research retreat at a beautiful French chateau, for Christian Kell’s wonderful group (department of neurology of the Frankfurt University hospital). During the Saturday-night workshop I presented our project and explained and demonstrated some principles of sounds synthesis. We then set to work to create synthesizer patches that simulated neuronal mechanisms of cognitive processes. […]

First ECG, EMG & EEG recording (Windows)
This week, thanks to Robert’s work on the openbci to fieldtrip-buffer (see previous post), I was able to record the first EEG using the OpenBCI system during a research retreat in France, with Christian Kell’s wonderful group (brainclocks.com). It took some time to figure out the pin setup on the board, but we finally ended […]

OpenBCI working with Raspberry Pi
I compiled the openbci2ft application on the Raspberry Pi without any problem. The openbci2ft application interfaces the OpenBCI board with the FieldTrip buffer, which is a network transparent interface to real-time EEG data and which supports MATLAB, Python, Java and C/C++ interfaces to the data stream. The openbci2ft application is implemented as ANSI-C application, as […]
Yesterday my 32-bit OpenBCI board arrived. Today I have been working most of the day to get it to work with FieldTrip, which is my preferred rapid application development and data analysis platform based on MATLAB. OpenBCI comes with some example software. I was able to get the Processing example application up and running in […]

The Nike EEG headband
We are targeting the development at affordable EEG hardware and specifically have the OpenBCI system in mind. A 3D printed headset has been constructed in the OpenBCI project, but that is not (yet) easily available. Hence I am currently exploring some ideas for electrode attachment on my own. Although easy to put on, a hard-plastic headset is not trivial to […]
Last night I talked for hours with my dear friend David Holmes – a true thinker and inventor, expert in music and meditation, and uniquely talented writer (see his wonderful book on the mind, brain and its intimate relationship to sound and light). It was a crash course on harmonics, timbre, resonance, overtones and the […]
Robert has been busy programming the first MATLAB-MIDI interface, in both directions. You can find the code on the Github repository. Here you can see him playing his MIDI piano using the MATLAB GUI that he made. And here the MIDI piano is played, displayed on the MATLAB GUI.
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 […]
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 […]

Brain waves at Södra Bar nightclub
On February the 7th, 2015, as the final party following Ouunpo‘s Art-Science festival called The Fugue, Jean-Louis Huhtna performed at the nightclub Södra Bar of Södra Teatern, Stockholm. He started his set by mesmerizing the audience playing sounds created from his brain waves.
SP Escola de Teotro, Sao Paulo, Brazil Per Hüttner, Stephen Whitmarsh and Jean-Louis Huhta joined forces with Brazilian actress Teresa de Almeida Prado and Portuguese actor Pedro Penim to revisit at Samuel Beckett’s last play “What Where.” The session took place in Sao Paulo in November 2014 and was divided into two sections. The first was devoted to recording […]
