Title: eeg with arduino
Post by: ruvido on Jul 27, 2013, 10:55 am
hello to all
I would like to build an EEG with Arduino. There are many projects on the net. I was wondering what is the most valid? I would measure 14 EEG channel names based on the International 10-20 locations are: AF3, F7, F3, FC5, T7, P7, O1, O2, P8, T8, FC6, F4, F8, AF4.

Can you help me with this project? thanks

The modular analog boards have two channels each (each channel has a + and a - electrode).

You have 14 electrode locations so that's 7 pairs or 4 boards worth.

that is, how should I build?
can you be more clear?

Buy the kits and build according to the build instructions?

Pick your board: http://arduino.cc/en/Products.Compare (http://arduino.cc/en/Products.Compare)
Personally, I like the Mega2560 due to maturity.

Before you buy anything, research the required amplifiers needed for EEG.  Are you going to buy a headset or build?  What electrodes?  Are you technically "up" to designing and building the amps? http://www.teuniz.net/12-ch_EEG_amplifier/ (http://www.teuniz.net/12-ch_EEG_amplifier/)

Flow ---> electrode ----> instrumentation amps ----> filtering -----> Arduino

I think you should make that decision.  However, if the decision comes down to an Arduino concern, ask your question but be specific.
