Iāve already posted about my Illumaphone ā hereās the project it was built for! For our final project in my electronic music class (taught by Jeff Snyder), we were basically given free rein to do whatever we wanted. My friend Harvest and I chose to build two āinstrumentsā and perform toether. As luck would have it, we had recently won a NeuroSky Mindwave headset in a hackathon (thanks, Twitchy), so Harvest decided to try and sonify his brainwaves.
The NeuroSky came with a toy helicopter you were supposedly able to control with your mind. Turns out the helicopter didnāt work so well, but the NeuroSky was really fun to play with. Sold as a sub-$100 EEG headset, the NeuroSky website trumpets its educational uses. Iām not sure if I would expect magical brain-training from it, as the āattentionā ratings and so on it broadcasts donāt seem very reliable. However, Harvest was able to actually get it to respond to his attempts at meditation. It works by resting aganist both your forehead and clipping to your ear. As we discovered, this means that itās also sensitive to things like grinning widely or raising your eyebrows.
The sonification Harvest eventually settled on focused on algorithmically generated musical patterns, guided by the brainwave data. When his āmeditationā value spikes (as interpreted by the NeuroSky), the music fades out into a raw sonification of the data streaming from the headset. Meanwhile, Iām playing my Illumaphone. Both instruments utilize ChucK, a musical programming language.
Hereās a compilation video of the final projects from the class, featuring a pretty good shot of Harvest and me up first.
And hereās our final performance, in full:
We had a good time. Thanks to Jeff for running an awesome class; now I have to figure out what projects to tackle nextā¦
