You would need two EEG-SMT units for that; four active and one passive per device I believe. There are some issues with running two EEG-SMT units, something to do with the USB ID assigned to both devices if my memory serves me. I only have a single EEG-SMT here so I haven't yet experimented with a dual SMT setup. ________________________________________ From: Rodrigo Perea [[email protected]] Sent: Tuesday, February 05, 2013 10:54 AM To: [email protected] Subject: [Openeeg-list] FW: Hello all, 3 beginner questions Thanks for the reply. So, if I need 8 active electrodes. Do I need to buy 2 Olimex EEG-SMTs? Just buy the Olimex EEG-SMT and be done with it. https://www.olimex.com/Products/EEG/OpenEEG/EEG-SMT/ You also need four active electrodes and one passive electrode. That's a high quality amp that connects via USB to the host computer.

Thanks to all who helped working out the insights. I have four questions I would like to clarify: 1.It looks like Olimex have different models now on sale so I was wondering what model is the most recently recommended. 2. Additionally, I was wondering if I need a digital and analog PCB per every two electrodes, since I've seen only two channels in the amplifier board? So essentially for four electrodes, do I need 2 analog and 2 digital boards? 3. I am thinking about using Pedro's dry electrodes. Is there any digikey/other electronices bill of materials that people could share? Any additional information about the silver electrodes? Thanks in advance for all your work!
