We invite Adafruit or some other developers to pick up PiEEG & to resolve the issues with noise it most probably has

A year ago, Adafruit introduced PiEEG:

Now it is available from Elecrow:

And there is also a forum for PiEEG. But it seems that hardly anyone seems to buy PiEEG or use the forum:

We heard some rumors that issues with noise could be the cause of that.

William Croft writes in the www.openbci.com forum about PiEEG:

„The PiEEG has a Github I believe. AJ Keller’s project never produced any products beyond his prototype. Not sure if AJ even had the software to drive the board. PiEEG comes with software.

For safety reasons, any EEG system should be either battery powered, or comply with IEC 60601 medical standards. Neither of these board comply with 60601. Nor does OpenBCI, but those boards ARE battery powered.

I would be cautious with the PiEEG design. Some previous noise measurements I’ve seen, imply that they may not be complying with Texas Instruments “star ground” / multi-plane design standards (shown in the data sheet). And PiEEG recommends you connect the Pi digital Ground pin to the client. (As a noise reduction workaround.)“

Adafruit wrote blog posts about the Muse headband a while ago:

But to use the Muse headband for own developments have become very difficult:

Do you have issues with connection your Muse headband to your Raspberry Pi? – try OpenBCI or PiEEG instead

And Adafruit also used OpenBCI Cyton for blog posts:

Products from www.openbci.com where criticized by users to be expensive. PiEEG is less expensive, but needs some testing, and eventually some modifications to reduce noise.

Adafruit has the experts to perform some tests and help to solve these problem. And Peter Gamma from www.petergamma.org invites Adafruit and other developers to help us to do some tests with PiEEG and to help solve the issues it potentially has, especially those with noise.
