Michael @MKnierim , hey thanks so much for your detailed reply with research paper citations ! Frisardi, reply on this thread if you have any followup questions. I also replied on your other thread regarding triggers / stimulators. Best regard…

Frisardi, hi again. Michael Knierim is the developer and expert on the cEEGrid electrode system. I'm going to mention his profile here on the Forum: @MKnierim , hoping that he might pop in here with some experienced remarks. But if that does not …

Hi Frisardi, In addition to the 8 or 16 EEG channels, Cyton can record external device opto-isolated trigger channels, as 'aux input' channels. But Cyton has no OUTPUT trigger generation capability. This page shows what auxiliary channels (pins) …

So your statement: This system functions as an artificial neural bypass to restore functional information loops in patients with Unresponsive Wakefulness Syndrome (UWS) or Minimum Conscious State (MCS). Really just mentions a POTENTIAL…

Hi PJ, You mention: This system functions as an artificial neural bypass to restore functional information loops in patients with Unresponsive Wakefulness Syndrome (UWS) or Minimum Conscious State (MCS). Can you mention any testing …

The only element on the headset that can 'wear' are the electrode tips. Did you get any useful info from your emails with customer service? I assume when you said "...but they do not seem to have changed in color", that you were examining the TIPS o…

Sure. Don't forget the 'Google Search OpenBCI' button in upper right column. OpenBCI Cyton schematics / layouts are here: https://docs.openbci.com/Cyton/CytonSpecs/

The datasheet, section 12 Layout has good advice. https://www.ti.com/lit/ds/symlink/ads1299.pdf

Designing mixed signal analog / digital boards, is considered somewhat an art form. And many considerations must be met to achieve a good mixed signal design. https://www.analog.com/en/analog-dialogue/articles/staying-well-grounded.html

Melon, hi. Yes the cables have single female header connectors that slide onto any header pins, regardless of manufacturer. William

Max, thanks for that sector write bug workaround. I've forwarded to staff engineers.

You are using the Ultracortex headset? Or some other type of cap? The silver chloride, dry, combs used with Ultracortex, can wear out over time. Check the tips of the combs, they should be the same grey as the body of the comb. If you see any oth…
-
Yes, send an email to (contact at openbci.com), which will open a ticket. What electrodes / electrolyte are you using? Could the issue have something to do with poor skin contact?

This is the result of using the 'Advanced Search' button at upper right: https://www.google.com/search?as_q=railed&as_sitesearch=openbci.com Another area to look at is the electrical environment, in terms of EMF Electromagnetic Fields. EEG…

See this related thread: https://openbci.com/forum/index.php?p=/discussion/2178/accessories-for-cyton-smaller-battery-case Cyton draws about 50 milliamps of current from the 3.7V lithium cell used. Divide the capacity of the cell in mAh (milli…

Did you READ the previous link / search I gave? https://openbci.com/forum/index.php?p=/discussion/201/large-millivolt-data-values-fbeeg-full-band-eeg You just need to filter out the DC Offset. Use a high pass or bandpass with a lower limit of …

Hi Raghul, For this complex issue, you need to open a ticket with Customer Support. Send an email to (contact at openbci.com) and you can link to this Forum post. Firmware updates can be detailed and multi-step, depending on which set of firmware…

Hi SHatch, I interspersed a few blank lines in your single paragraph original post, to make it a bit easier to read. Do you have any idea what changed between last year when everything worked fine, and this year? For example could be your lab …

Hi SManne, Since your cap is a new purchase, have you tried emailing Customer Support (contact at openbci.com) and mentioning your degradation issue? As you suggest, the issue might be related to your first day of use allowing the remaining gel t…

Richard @retiutut, hi. User @shaluska is trying to use Processing IDE to run your fix pull request. But is getting an error that NetworkDataType is not defined anywhere. I just went to the Github GUI folder and indeed that definition is nowhere i…
-
Have you tried a 'grep' or string search for the function name NetworkDataType ?
-
So don't REPLACE, just add the new file.

OK, well seems to be TWO related files, the one that is there, NetworkStreamOut.pde, and the new one NetworkStreamOutOSC.pde

It replaces the existing file in the main OpenBCI_GUI folder: https://github.com/OpenBCI/OpenBCI_GUI/tree/master/OpenBCI_GUI
