Ok, so best is just 8 channels Cyton + PulseSensor .Or, if I use the wiifidhield which can transfer at 250Hz, should I suppose the Daisy+Cyton+Pulse would be still perform well? Thanks in advance
-
Hi very usuful. I am planning to use the 16 channels plus the pulse sensors using the datastream through python: in this case can I use it on the aux channel at 125 Hz as the other channels? (William wrote that the widget GUI expect 250Hz for the p…

It works. I don't know why but with the IDE it works. Thanks.

Whenever I click on the 'Cyton' button on the GUI I got: 'unable to establish link to hub'
-
The way I run the GUI is as follows:1. dowloaded the application.linux64.zip 2. extracted cd application.linux64 3. sudo ./OpenBCI_GUI

I am using Ubuntu 18 lts. As far as I know /dev/ttyUSB0 is quite standard

here is the error on OpenBCI_GUI: OpenBCI_GUI::Setup: Is RX mulitcast: false OpenBCI_GUI::Setup: Has RX joined multicast: false java.net.ConnectException: Connexion refusée (Connection refused)

Found something: if I specify the port using OpenBCI master like:sudo python OpenBCI_Python-master/user.py --daisy --add csv_collect raw_00.csv --record-duration 111 --safety-duration 3 --port /dev/ttyUSB0 then it works. Is there a way to sp…

Not sure it is normal but I got: andrea@andrea-XPS-15-9570:~/Téléchargements/application.linux64$ udevadm info --attribute-walk --name=/dev/ttyUSB0 Udevadm info starts with the device specified by the devpath and then walks up the chain of pa…

Does the dongle show up as a /dev/tty* port when you plug it in, and disappear when you unplug it? Yes it does However for openbci it cannot find it
-
I use to allow the dongle with sudo chmod 666 /dev/ttyUSBN where N is the number of the port the dongle is in. It ddoesn't work anymore...

I just did a test on the electrodes. Apparently the screws were a bit loose and the channels were railing. I now tight the screws and the railing quite decreased (or it is negligible). Here is a question is there any suggested 'conductive paste…

@wjcroft 'However the Ultracortex instructions show Bias and Reference connected to opposite ear lobes.' that's what I did. But if I put both the reference and the bias in my earlobes many channels get railed on the GUI. If I just put on the bias no…

@wjcroft Do the electrodes "look the same" as when you first got them? Yes I am using the the electrodes provided for the Mark IV so no gold cup. At sight I cannot see any difference. I can say one thing though: I can see less railing using only 1 e…

@wjcroft thanks. Just to update here what happens in the following scenarios: To anyone, Is there any suggested way to clean the electrodes?
-
Hi, I just bought the device in June... but yes I will try with different electrodes. Anything else I can do?
-
I bought a Mark IV headset (large) and the cyton/daisy board. At the beginning both using the GUI and the python script me and a couple of collaborators we had no problem in recording all the 16 channels. Now it seems the system it's becoming very …
