A friend shared this link for an open source design for building your own EEG device for tracking/monitoring/recording your various brainwave activities.
This could prove interesting for diagnostic purposes for healers...granted, if you can read brainwave speak...but also allow for an interesting opportunity for the home user to understand and practice healthy forms of thought patterns...
It would be interesting to track peoples responses to what they are eating/feeling/thinking. Gives a new dimension to the intake process!
What do you guys think of this...useful, abuseful, or fluff.
