Interesting... what sort of meditation is it ?

In the last week Rob has adjusted his software to the RS232EEG hardware.
I have done some noise measurements and got approximate 1uVpp noise (RTI)
with the old design.

BTW: how much noise does the brainmaster have ?

In the picture you can see a calibration signal (50uVpp, 10Hz, rectangle)
and an eeg-sample.

> have you got any problems that i can help with from here ?

Not really.

But I think it should be checked if the the patents for the brainmaster
are violated by the RS232EEG design and /or Rob's software.

Another important matter is to get answers to the liability,
regulatory, and insurance issues connected with producing
an eeg-device or assembly kits.

Regards,

Joerg
