I don't use the Bias pin, what is that for?
-
I use NuPrep abrasion before applying Ten20 gel. Yes, I am saying that my peaks could be due to the reference electrode on the mastoid. My reference impedance is generally low. Probably I don't place it on the correct bone every time so could be con…

I tend to change boards if one behaves weirdly. I do get noises-same or different in both. I think I agree with you that board isn't the problem. I do place my reference electrode on the left/right mastoid, so that explains the issue. MAybe whenever…

I don't think its the local environment because the one that had initial errors are still behaving that way in another location. Now I am using brand new Ag/AgCl electrodes with Ten20 gel, same with both.

Just to be clear, I do not have any Cyton. These ae 6 channels because the last two are bipolar derivations from 1-2 and 3-4

Hi This is from Ganglion too and I am getting these bursts for the first time if I recall correctly. Now I have both the open BCIs I can check signals from both in the same environment. I use one if the other is producing noises. Whats the best way…

I connect it on forehead. Unfortunately it is not possible to test both simultaneously now as both are in different countries. I can test both in a month when i have them together.

Hi! Thanks for the feedback. But the same happens in now 4 different environments on all people. I don't know why the electrostatic buildup would happen even after opening the encasing. Before a month i was using another Ganglion and it seemed to w…

Now I remember the BP is always on. Nevertheless here it is: https://ibb.co/tQDDkvR https://ibb.co/2NjvR0B https://ibb.co/hLGMvYJ

I can share here the raw files of what I am referring to. No in the FFT everything goes higher during those dual peaks, actually sways up and then comes back to normal. In the GUI I don't switch on the band pass. Yes, it is fairly similar.
-
Now at least it is not sampling slow frequently, but the dual peaked high amplitude is my concern that happens abrubtly.
-
Both notch 50 Hz and band pass 2-35 . But the raw signals reflect it and despite the 50Hz notch on Open BCI GUI, it is evident always. I know the notch there is only for viewing . Radha

Well to troubleshoot the problem, we tried various things: 1. Changing electrodes doesn't help 2. Streaming LSL so could be a memory issue causing packets to loose, but NO, I have 32 GB RAM 3. Read on another forum that it can be a charge accumu…

I am running standalone open BCI v3.4.0 with open BCI hub v 1.4.5 , Ganglion on Windows 10 64 bit. I am trying to stream LSL from Open BCI but the GUI freezes. It did not freeze only once/twice in between. But it freezes now. any suggestions? Do I …

Link for older versions: https://github.com/OpenBCI/OpenBCI_Hub/releases?after=v1.4.0 shifitng to an older version of bcihub 1.3.9 resolved my problems of ganglion not seen on open bci.
