How to hack a toy EEG.
A quick tutorial on how to extract serial data from the $80 Mattel Mindflex (mindflexgames.com). The hack also works with the Star Wars Force Trainer.
More information and detailed instructions are available here: frontiernerds.com/brain-hack
I wrote an Arduino library to encapsulate the software-side of the hack into just a few lines of code: github.com/kitschpatrol/Arduino-Brain-Library
And here's a Processing-based brainwave visualizer: github.com/kitschpatrol/Processing-Brain-Grapher
This hack was originally developed for Mental Block (mentalblock.net), a project I worked on with Arturo Vidich and Sofy Yuditskaya.
(Also, a safety note: You do not want wall power anywhere near this circuit. Only plug the Arduino + Mind Flex combination into a laptop running on batteries alone.)
