Thank you for the reply. Sorry for the delay, as it appears that this branch is gone, maybe merged into development build for upcoming release? Is there a place to download an installer for latest build? I would be happy to do some testing if I can…

To follow up for anyone else who has interested, through experimentation I have confirmed the answer. When you use CytonSDK channel command and set bias to for a channel, it shows up in both the SENSP and SENSN register. Here is register report …

William Thank yo for prompt reply. This is all very helpful. I have looked at the data sheet. I see where the register bits map to the settings value for all items except one. OpenBCI Cyton SDK documentation talks about a single 'bias' setting. I…

If you have a soldering iron, you can easily repair the broken wire. Simply strip a bit of insulation off the remaining wire and solder it to the back of the electrode holder. You can even make your own electrodes connectors from a few spare parts…

William Thank you very much for your prompt reply. Although I did search first before posting this question, after the fact I found this post on the OpenBCI forum which also explains the same thing: https://openbci.com/forum/index.php?p=/discus…

For what it is worth, I am also a newbie and I am working on a blink detector as a first project to understand more about EEG signals. I wrote up a bunch of notes with observations (and unanswered questions) that might help others who are also just…
