Your clarification on the Cyton Board being DC-coupled and the Ganglion Board incorporating a high-pass RC filter, not a bandpass filter, has provided me with a clearer understanding. Additionally, learning about the AC coupling mechanism and the fe…

Thank you for your prompt reply and for providing detailed explanations. I now understand that the Ganglion Board incorporates a bandpass filter that cuts out any frequency below 0.3 Hz, a detail I found in the OpenBCI documentation. Furthermo…

Hi William, First of all, I would like to thank you for your prompt response to my query regarding the OpenBCI Cyton Board. Your information have been invaluable. Now, I wanted to dig a little deeper into the concept of DC coupled EEG amplifiers…

Thank you for the clarification. I now understand that I need to calculate the FFT bin widths based on my board's specific recording conditions, such as the sampling rate. Your prompt response is greatly appreciated!

Hi Jarek, Thank you for your continued support and dedication!

Hi William, Firstly, I'd like to express my sincere gratitude for your swift and comprehensive response. Your detailed explanation provides much-needed clarity on the situation. In light of your advice, I've decided to revert to using the v2 f…

I am also getting this issue, for v3.1.1.

Hi William, As you pointed out, the latest GUI, OpenBCI_GUI-5.0.0-beta.0, seems to have fixed this problem. We are currently testing it. Thank you. Otemo
-
Thank you William. Your detailed description will clarify what we should inspect. ok, we will continue to investigate the cause and report it here, and wait for the delivery of the new GUI!

I tested it under the combination condition of Lenovo x270-Brainbay-BLED112 (Hub-v2.1.0). As expected, artifacts were detectable.

Thank you William. Here are our information about Win Machine [ Lenovo x270 ] - Artifacts detectable Windows10 Pro version: 1903 date: 2019/08/29 OS build#: 18362.592 [ HP Probook 450 G3 ] - Not detectable Windows10 Pro version: 18…

Hi there: Today we tested using three Windows machines (lenovo: x270, hp: 450G3, panasonic: cf-sv), combining two Ganglion boards and two BLED112 dongles. The results of the test gave me enough facts to suspect that the cause was on my laptop(…

Sure! We will examine each possible factor. Thanks for your advice. Otemo

Hi William and Richard, We always appreciate your quick response and help! Last spring we changed the usb dongle from CSR to BLED112. From the time, we were seeing this artifact, but we thought it was probably due to environmental noise. Fo…

The support team informed me that they have updated the docs pages. Thank you so much! EEG setup with Ganglion: https://docs.openbci.com/docs/01GettingStarted/02-Biosensing-Setups/EEGSetup#1-connect-your-electrodes-to-openbci EMG setup with G…

I have submitted the issue. https://github.com/OpenBCI/Documentation/issues/13

Hi @retiutut, i appreciate your advice!

I have confirmed the same phenomenon. However, this phenomenon has been confirmed only when BLED 112 dongle is used. Also, when I connect with Ganglion using CSR dongle, impedance can be measured without problems. Here is my environment. GUI …

Hi William, I appreciate your always prompt advice and support ! I will postpone the 1809 upgrade according to your suggesiton. Otemo

Hi There, I have found one of the causes of this problem. My antivirus software seems to interrupt the GUI's startup. After uninstalling the antivirus software, the GUI ran without any problem. I have gotten the information that this a…

Hi, Willian. Thank you for the quick response! I am going to try all the methods that you suggested. I will also report the results to you. Otemo

Hi William, Thank you for your advice! I have checked the information of my OS. edition: Windows 10 Pro number/version: 1803 install data: 5/25/2018 os build: 17134.228 Is it possibility that my anti-virus software blocks the GUI st…

Hi There, GUI 3.3.1 beta 1 works without problems! Thank you.
-
Thank you William, I will try it. Otemo
-
I could have solved this problem by myself. Sorry! The GUI recognized the Cyton board. It seems there was a problem with the charging method of Lipo battery. Thank you. Otemo
-
Hi There, I used a 3.7v Lipo battery(860mAh), fully charged, on the Cyton with the WiFi Shield. To passthrough power to the Cyton, I kept the EXT PWR switch ON. I could see the WiFi board in the OpenBCI GUI using the direct WiFi mode. Howe…

Hi There, New Openbci Hub v1.4.2 does work. Thank you William and AJ! However, I can't conect cyton board, playback the archive data using new OpenBCI GUI. No matter how many times I try, OpenBCI GUI v3.3.0. freezes. Does your OpenBCI GUI …
