OpenEEG - EEG hardware and software

hi all:

        I got some problem when I play Brainathlon Game, I can not use my
brain wave to control the red ball
        I am working from 1 digital and 1 analog board, ordered assembled
from Olimex
        I have finished steps from open eeg webpage for my device
        When I close and open my eyes , I can clearly see Alpha Wave
increase or decrease on my screen

        however,I still cant control in the Brainathlon Game
        What's my problem?

       I will appreciate for reply my question.

       Thank you, have a good day!

Hi All

I am looking for an article that appeared in the Measurement Science and
Technology Journal:

"An ultra-low-noise electrical-potential probe for human-body scanning"
R J Prance et al 2000, Vol 11 291-297

Has anybody got a PDF copy??

I am using modularEEG hardware.. i want to obtain 3 channels which are
Cz,C3,C4.
But i don't know where i hav to connect the electrode in the board...
For example in the board for one channel the electrode connection is marked
as CH1electrode+ and CH1electrode-.
Further they have mentioned right leg driver electrode...
what is meant by reference and ground electrode
