I was wondering if it was possible to play with your mind to control things via an Arduino. So i tried to find informations on internet and it seems not to difficult to hack the MindFlex product. But the price of this product is high so I thought it's probably possible to build this by myself.. There is still a lot of things that I don't anderstand. So correct me if i am wrong.
To build an EEG sensor, we need several electrodes, which can be active or passive. I found for exemple those : http://www.gtec.at/Products/Electrodes-and-Sensors/g.SAHARA-Specs-Features http://bio-medical.com/products/emgeeg-sensor-pellets288-pack.html
When you have you electrode you need to fix them on your head by building a headband like on this vidéo
And then I guess you need to read the informations from the electrode... do you think it would be possible to plug them directly to an amplifier and to the analog PIN of the Arduino?
It seems that we have to read wave between 0Hz and a little bit above 40Hz (Delta to Gamma) does it work like reading sound frequency with a micro electret?
Thanks by advance, any informations would be helpful!!
