Arduino EEG
Hello all,
I am a high school student taking a bioengineering course. My project partner and I are trying to make a device that can analyze the user's sleep patterns. We are trying to figure out the best way to make a DIY EEG with an arduino. We have seen some tutorials such as chipstein and openeeg. However, none of them seemed easy to follow or explanatory enough for us, nor did they show how to implement more than 2 electrodes. We were wondering if anyone has any better resources for us. Does openbci have an shield we can buy? OpenBCI seems like the perfect fit for our project.
Thank you and happy new year,
Jonathan

Thanks for your interest. OpenBCI is currently running a kickstarter as a way to release its first units (<a href="http://www.kickstarter.com/projects/openbci/openbci-an-open-source-brain-computer-interface-fo"; title="http://www.kickstarter.com/projects/openbci/openbci-an-open-source-brain-computer-interface-fo">http://www.kickstarter.com/projects/openbci/openbci-an-open-source-brain-computer-interface-fo</a>
If you could be satisfied with two EEG channels, then OpenEEG is available now via Olimex. If you want more than two channels, and can't wait for OpenBCI, you're in a tough spot. There's not much available.
You could get an Emotiv headset and buy the software development kit that allows you to get access to the raw EEG signals. I'm not sure what that costs, but it isn't super cheap. And, the headset might be tough to wear while sleeping.
If you're good with soldering iron, you could try building your own many-channel EEG system by building off the OpenEEG schematics. That's not a trivial process.
If you can't wait for OpenBCI, my vote would be to stick to a 2-channel system like OpenEEG. You'll still have a challenge of picking electrodes (I personally don't like the electrodes that you can buy from Olimex), adapting your electrodes to fit the OpenEEG connectors, and figuring out how to actually wear this stuff while trying to sleep. That's a long enough list of challenges without also trying to figure out your own many-channel EEG setup.
Good luck,
Chip

Like you, his purpose is sleep monitoring. He's also got some software to help with the logging of sleep data from the Olimex (and other?) hardware:

I make no claim that any of this is good or useful, but it does seem applicable to what you were asking about.
