updated on 16 June 2014 for Section 9:
you can go directly to Section 9 also.
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 amp noise test.
Section 5 is all construction
Section 6 is head set 3D model and stl files
Section 7 is example of brain wave interactive animation.
Section 8: INAMP-OPAMP + PCB eagle files + 16 bit brain wave interface for Arduino and Raspberry Pi : updated 10 Jan 2013
Section 9: Open brain hacking : included new PCB, 24 bit interface, etc. : updated 16 June 2014
This brain wave interface hardware work with Mac:
IBVA V184.108.40.206 : not free. all IBVA user since 1991 can get this free upgrade.
Quartz Composer IBVA plugin : free : you can make own visualization and interaction with Quartz Composer.
and PC user can use Brainbay with IBVA plugin for OpenEEG project. : free
