@biomurph, understood. We purchased the 16ch kit so we could detect 16 channels of EEG signals on a subject, and we're not going to make the poor guy wear THREE earclips! So I just clipped one of the wires that had the pin socket already crimped (f…

Thank you @wjcroft! So for the case of using two ADS1299's in daisy config, in order to detect 16 channels of EEG data ... why isn't the situation the same for the SRB2 pins on the two boards?? And since it is the case that a Y adapter is needed .…

@wjcroft I'm going to assume the comment "The BIAS_INV connection between the main board and daisy module makes connection between every channel that has 'include in bias' selected from the GUI. That pin is not the electrode BIAS output! The BIA…

Hello @wjcroft , thanks for the reply! 1 - good idea! That's a better solution than having it hang out on the cord. 2 - Why are the two BIAS the same? I confirmed with a meter that the BIAS pins and the BIAS_INV thru-hole are not the same node. So…

So, are the following two actions the "unofficial" recommendations of this thread? 1) purchase the JST extension cord so you don't have to unplug from the main board socket -- and for those who install the main board in the Cortex board holder, hav…

Update: I've run the GUI several times now from Ubuntu 14.04 bash shell (using 'sudo bash OpenBCI_GUI') and it has never yet frozen my system again. Not sure why it did the first time, but oh well. Gotta break a few eggs to make an omelet. Then ag…

I used 'sudo usermod -a -G dialout [user]' to add my user to the 'dialout' group, but that still gave me the error message "[Errno 13] Permission denied: '/dev/ttyUSB0' ". Then I used 'sudo chmod 666 /dev/ttyUSB0' to add 'rw_' for all users. That d…

I was seeing the same error code, trying to just start the GUI for the first time on Ubuntu 14.04. They really don't give much help for linux users. Had openJDK 7 installed, so I removed that and installed Java 8 using this link: http://www.webupd…
