makes these headsets and sells them to students and hobbyists. OpenBCI , a Brooklyn - based technology company , has developed a 3D - printed headset called Ultracortex Mark IV , which captures EEG brainwaves and EMG face muscle movements , converting these into circuit board signals to operate anything from a remote - controlled helicopter to a robotic arm . Each headset takes 25 to 30 hours to make , costs $ 100 and all the hardware and software is open source , unlike many of its competitors . The company has plans to design a new version of the headset that can send electricity into the brain as well as out of it , through a technology called , transcranial direct current stimulation technology ( STS ) .
