Hackers in Residence - Hacking MindWave Mobile
Taking it Apart
Pictured here is the MindWave headset. Nick Poole took one of these apart, so the insides of the headset are pictured here as well.
Here is a closeup of the internal circuitry. You may recognize the MSP430 hanging out at the top.
And, the backside….
In between the two boards is an ASIC. The ASIC on the Neurosky calculates a value for Attention and Meditation. It also processes five types of brainwaves (more on this shortly) and sends out unitless values for each one. This unit measures eyeblinks too.
