Later during the research for our robot Maxi Wanzl, we stumbled upon the openEEG project. It offered EEG for the rest of us, but you would have to build it yourself. The technical department became sceptical: Not another D.I.Y. prototype that requiered months of work.
So one year ago, when Cycling 74 published the news about an EEG-machine that came with its own maxMSP patch at reasonable prices, we rejoiced. Finally the possibility to work with an interface device that goes both ways. With this we can make the brain control lights, music, video, etc. Or we can register and store the brains reaction to these impulses.
