+However, the same thing happened again, and sugar was added a third time, aok.  Still, it may well be worth making the correct yeast media, rather than just adding sugar to the yeast in water!  If enough alcohol is made, of course the yeast's 'singing' might be compromised!

 Living Instruments is a collaborative project between Swiss musician [http://www.sergevuille.ch/ Serge Vuille] (under the umbrella of the project [http://www.wespoke.ch/ WeSpoke]) and the DIY science crowd of the community laboratory Hackuarium.
 It creates musical compositions with a series of instruments that use bacteria, yeast and other living organisms, with some extra DIY tech (Arduino etc), to generate music.  By interacting with the organisms and recording the sounds, gas bubbles, pressure, and movements they generate, the artists can transform data into music, creating a live, semi-improvised musical piece.

-Here are some images (to the right):  1) our old mascot with our simplest eeg and the sensor for the bubblers of the yeast organ on one leg; 2) Esther at our table in the Waldhaus - where the mossophone also got some good tests (Pure Data isn't a simple learning curve, but might be useful.)
+However, even with her special EEG cap, and electrodes, apparently, the EEG signal needs such a long time to stabilize (not to forget the need for Lina to shave little patches of her hair away to allow the EEG electrodes to have better access, esp to dab the special gel), she warned us that our big aim to use the human brain as an instrument, live, with people coming and going, would be very difficult.  So, although we hope to make more progress in that regard, we will not be able to do the EEGs for the event at the museum, sadly.

+@ #OHs and other days, for instance, with Yngvar, in early August, got a little sketch together to run a little speaker based on the capacitance measurements.  It doesn't sound pretty but gives more of an idea than just seeing output numbers or the serial plotter graphs from Arduino IDE.

 Getting the Moss-o-phone on line with the capacitance sensor is a second important task, facilitated by Richard at the FabLab of Renens. Trying to get the EEG together, with two electrode options, the expensive ones were ordered and arrived today (30July25), and Yngvar's DIY dry electrodes, is another big aim.
