make high quality brain wave interface as low cost and small size is my over 20 years of dream. to do so need mass production, need work with investor to realize that way. not just only my thinking many people ask me to have low cost brain wave interface but i didn't succeeded many years. Still i sale expensive brain wave interface system.
however recently we can get parts, micro controller more low cost, small size and more easy to do custom programing. So I made 3 different prototype first. then make actual low cost interface.
Section 1 is how i made prototype over 20 years ago and new prototype 1, 2 and 3. including Arduino code and test code.
Section 2 is circuit diagram for actual new design brain interface based on prototype 1, 2 and 3.
Section 3 is small size brain interface on going project.
Section 4 is example of brain wave interactive animation.
This brain wave interface hardware work with Mac:
IBVA V5.0.8.5 : not free. all IBVA user since 1991 can get this free upgrade.
Quartz Composer IBVA plugin : free
and PC user can use Brainbay with IBVA plugin for OpenEEG project. : free
following is step by step instruction for this. photo is prototype 1, movie is prototype 2.
1: making of open brain wave interface hardware prototype.
2: open brain wave interface hardware circuit diagram.
