This basically involves adding a Bluetooth serial transmitter (and configuring it) to the Mindflex Headset and changing some components on the TGAM1 board (the board that acquires the EEG data).

This ended up being a bit of an adventure – even after a good deal of research (reading datasheet's very carefully) and reviewing other peoples tutorials of similar hacks. In the end, it took about a week of part time research on components, Bluetooth (profiles, module boards, communication protocols), TGAM1 board (communication protocols, identifying board connection points, hardware settings etc.). Presently, I have a fully functional headset that is recognized by Neurosky's MindWaveMobile software as a MindWave Mobile Headset.

• Mindflex Headset ($10-20 on ebay)
• HC-06 Bluetooth Slave Module (that communicates with Serial Port Profile (SPP))
  • these are between $5-10 on Amazon or Ebay (cheaper in quantity, or if you are willing to wait, from China)
  • should be able to use an HC-05 also (connections and configurations a little different – HC-05 can be configured either as a Master or a Slave module – unlike HC-06 which is only one or the other)
  • I'm a noob concerning Bluetooth: protocols, host modes, etc.
• 10k resistor (pull up to set TGAM board to 57600 baud, ¼ or 1/8 watt)
• Hookup wire

• Soldering iron (and solder, of course)
• Multi-Tester/VOMeter (non-essential - mainly to verify connections)
• Magnifier (non-essential - to see TGAM1 board pins and labels clearly)
• 5V to 3.3V Level Shifter (essential if using an Arduino board to set up the Bluetooth module, non-essential otherwise)
• Arduino Board with USB connection
  • Software Serial sketch
    • This is what I ended up using and it worked fine – though you do need to upload the sketch a few times:
      • Change baud rate of module
        • change software serial baud rate – reload
        • etc.

Here are a couple of screen shots of the headset working with a couple of applications:
