What are you working on? June 2012

This is the bimonthly 'What are you working On?' thread. Previous threads are here. So here's the question:

What are you working on?

Here are some guidelines:

Focus on projects that you have recently made progress on, not projects that you're thinking about doing but haven't started.
Why this project and not others? Mention reasons why you're doing the project and/or why others should contribute to your project (if applicable).
Talk about your goals for the project.
Any kind of project is fair game: personal improvement, research project, art project, whatever.
Link to your work if it's linkable.

From my experience: Mindwave has unusually good algorithms for filtering out blinks and facial movements, but the utility of a single electrode EEG is limited. Larger EEG arrays don't have algorithms as good at filtering out blinks and facial movements.

Thanks! I think you're right. I found a program that gave me "raw" EEG signals from Mindwave at different bands (theta, gamma...) and blinks and muscle movements caused huge spikes. But the Neurosky attention/meditation metrics were relatively unaffected. Unfortunately, this is a wheel I'll have to re-invent to extract good signals. (I assume so, since neurosky's metrics are proprietary.) Though I hope some literature exists about this.
