correction Neurosky chip not Bluesky chip…

Hi there Louis, its been sometime since ive experimented with the headset, but i do have it still on my electronics bench with the intention of picking it up again. Im trying to remember where i picked up the information about the other channels, Could it be a limitation in the Audino Software, Maybe take a look at the data coming out from the board direct in a Serial Terminal app, Please let me know how you go on, The Bluesky chip should allow you to access all the channels directly from the headset chip, But i do know that only the three channels are sent back to the base station as its all the forcetrainer makes use of. I would love to get my hand on Emotiv’s Epoc headset, with full SDK not the restricted SDK.. regards Richard

Quadrant: nope, I just tried this using the brain library of arduino (https://github.com/kitschpatrol/Arduino-Brain-Library) and there is only three values : signal, attention, meditation. I`m kind of disapointed because I bought my force trainer with the intention of getting all the FFTs but now I got only those not very obvious proprietary signal

Thats correct there is raw EEG data available its in the headset available at a point marked T in the headset.

Hook T to serial Rx and gnd to gnd

The force trainer headset gives you 11 values in this order:
Connection quality, Attention, Meditation, Delta, Theta, Low Alpha, High Alpha, Low Beta, High Beta, Low Gamma and High Gamma.

I have a force trainer star war

that when I connect the headset TX and RX I put the arduino and the land of the crown to the other land arduino not read any data in the serial monitor

This hack might require tech on the receiver side in order to rexcord anything significant. as is it might not amplify the signal enough to get the signal visualized in a program. But the thing is an electrode so the sky’s the limit. The question is, I’f there is a signnal to an led light, how much amplification does the signal get from the toy to light that thing? After that it,s like shoot…

This uses neurosky’s technology, there should also be raw EEG values being outputted from that chip unless it’s intentionally be disabled by the manufacturer.

do you think it would interfere if there were two headsets and two receivers or the frequencies would differ between units?

Someone tell me when I can offload SIMD onto my brain.

Oh.. the frequencies are: 2408 and 2478 ghz

Max:
that’s not quite correct.
The force trainer has internal gains so to get always a signal.
brain signals and muscle signals interfere with each other so one can be misunderstood for the other.
Remember this is just a kids game.
It does a simple FFT transfor to get alpha and beta waves, but if you study the eeg basics you will find that muscle impulses (facial, eyes, your hand, whatever) can be interpreted in the same way.

@ Max: I hope not, already had a big technology let down with dyson’s little white lie.

Amazon.com comment suggests this doesnt actually read brainwave…

“It does not truly measure your brain waves to control the air flow as the game indicates. The headset merely uses your skin surface to complete a circuit and then it controls the fan. Not sure if the headset has the preprogramed routine, or if the base does. I confirmed this function by completing the circuit with my hand (i.e. – Using one hand, I made contact with all three sensors to complete the circuit). Now unless brain waves travel through your hand as well, which they don’t, the fan in the base began to turn on and off as if though I had it on my head. Thus confirming that the forehead sensor and other two sensors are merely positive and negative connections, and once connected, they complete the circuit and the headset then transmits to the base. ”
