If you can t reproduce Richard Davidsons experiments, and don t see any Gamma wave changes in the prefrontal cortex, build your own do it yourself gelfree Greentek cap with 128 EEG sensors, which can

The micro SD card is the st-tf-003A from SEEED Studios. You can email them directly for a quote.

Another sound card EEG,

Yes I am aware of the forum and I saw all the completed projects but there is still confusion in my mind like for example I am not sure if the SD card I have in mind is good with the project since th

but the problem is that no data is saved on the SD card after restarting the device in a running session although data is received on the laptop. (Is this the intended behavior?) Also, when start and

I tried with a 16GB SD card now that fullfills the requirements. But unfortunately, I have to confirm that the problems are still there.

I would try another SD card and reformat it. It's possible your particular SanDisk card is damaged or defective somehow. Though in general SanDisk is a good brand. Perhaps even try another brand. Ther

I would only suggest trying another SD card, perhaps smaller in capacity, and as highly rated as you can.

The message seems to say your OpenGL driver (from Dell), is not functional. Did you search their support site for a download of a new graphics chip / card driver?

The Neurosky TGAM module is ONE channel, and connects via a Bluetooth module to (for example) an arduino. It does not work with a usb sound card. There are a few TGAMs available on eBay and other rese

A system with sound card EEG as mentioned before in this thread is much cheaper:

there are a number of articles on using a sound card approach.

But anyway, we think that in terms of data volume and battery drain it would be better to save all the data on the SD card and just send commands to start and stop recordings as well as set configurat

Another idea is to use BLE just for communication not for transferring data. We'd like to save all data on the SD-card and just send commands (via BLE) to the Cyton board like "start recording&qu

BTW, any shortcut on how to save in my computer running the OpenBCI-GUI the received data by the WiFi shield for later analysis instead of saving in the uSD card on the CYTON board?

I have seen this with power problems when one battery pack is used for both cyton and wifi card, or when battery was low.

SD card on Ganglion was abandoned because of limitations in the Simblee CPU architecture. SDcard presence is not promoted in any way for Ganglion. Even though the socket is there.

For this application I just need to use it asap without any customisation. In other words only through the user interface settings. And through the menu I can select "write to SD card" ONLY

The issue states that 1000 Hz 16 channels works fine. You would have to test if you can go higher. There may be related issues with higher speeds in the SD card driver itself.
