Brain-controlled drone racing

I'm guessing its an emotiv headset (their calibration software is a floating cube). I don't think there are cheaper alternatives around, theres an openeeg mailing list which has some designs that can be built for a couple hundred bucks (not to be confused with OpenEEG which is a much more expensive, but (ostensibly?) open source product).

There was also an eeg64 project which looked like it had a lot of promise, but it hasn't been updated in a while.

Emotiv also do some machine learning to estimate the state of the brain from the changes in electric potential on the surface, I don't know if any other headsets do that, but its completely proprietary.

Can the link be changed? The DM is not only terrible journalism, it's a terrible business too.
