Totally man. So I used the Mindwave Mobile. I took code from a patch used for a previous NS headset. What I did was I found this piece of software called BrainWaveOSC, which was a user developed program to stream the headset data over open sound control. Then I took a patch on a previous thread, and updated the port number to correspond with the port number on BrainwaveOSC.
Attached is the patch I used to pick this up inside the Max MSP enviornment.
Hope this helps; let me know if you have any questions!
Keep in mind, there is not direct link from the headset to MaxMSP that I found. It HAS to go through BrainWaveOSC.
