I'd like to offer some feedback to openBCI on this topic. I have several Ganglion boards, as well as other products from openBCI, so I'm obviously an investor in the project with a stake in its success. The projects's handling of this developme…

William, Is there any word from from Larry to OpenBCI on support for the Ganglion? Does Bioexplorer support include support for the wifi shield? Thanks, Michael
-
Will openBCI be performing upgrades or offering parts kits for the modifications? Best regards, Michael
-
Does this mean that Ganglion boards already purchased need to be modified if the flatter filter response is required? Thanks, Michael

Winnie, Here are my notes on upgrading the Ganglion with a Mac: 1. Install Arduino in Applications and download OpenBCI_Ganglion_Library from github. 2. In Applications, right-click on Arduino and select Show Package Contents. 3. Place OpenBC…

Winnie, I also started with a PC and couldn't get the upgrade to work. Last time I looked, the openBCI tutorials still had no instructions for the PC. The tutorial for the Mac didn't work, either, but I found an alternative method. If you are ab…

Winnie, Could you tell me whether you using a PC or a Mac? I may be able to help if you are using a Mac. Best regards, Michael

Winnie, I'm using a different FTDI adaptor, but for mine Tx is connected to Tx and Rx to Rx. Your photos show Rx and Tx connections reversed. Also, I think the Ganglion board needs to be connected to batteries and powered on. Best regards, Micha…

I'm also a long term BioExplorer user. Despite several posts on this forum claiming that BioExplorer supports openBCI protocols, I've been unable to find any confirmation. The current web site and downloads show no evidence of supporting openBC…

The latest Bioexplorer version from the website does not support openBCI. As far as expecting support from the developer... well, you must not have much experience with Bioexplorer. Best regards, Michael

@wjcroft You've made several references to support of openBCI hardware by Bioexplorer. I've been a Bioexplorer user for 10+ years, so tonight I visited the Cyberevolution site and downloaded the latest version shown there. After a new install of …

>Yet another way to detect band activity is to use a VPL, such as OpenViBE, BioEra, Bioexplorer, etc. This suggests that Bioexplorer works with openBCI hardware. I see no evidence of that yet. Best regards, Michael
-
William, Agreed. But use of synchrony measures doesn't mitigate the need for a low noise channel. Wideband noise degrades precision estimation of phase in coherence calculations. It also reduces reliability of most other synchrony algorithms. T…

@wjcroft, Yep, I have several of those EEG amps from the old days. I'm seeing a minimum noise floor of about 1.4 microvolts rms from the Ganglion here, measured in a faraday cage with all inputs shorted to ground. There are also some differences …
-
@Mauricio, Most neurofeedback protocols use only a few active electrode sites, usually one or two. These are easily located by measuring. Thousands of neurofeedback sessions are run every day in this way by clinicians using gold or silver ele…
-
@wjcroft, could you confirm my understanding (below) of the resolution difference between the Cyton and Ganglion? While the Cyton and Ganglion both sample a 24-bit word, the Ganglion compresses that data and transmits only 18-bits. During worse ca…
-
Geraldo, If your electrode connections are reasonably high quality, you might be experiencing electrical noise from nearby electronics. The fact that holding the board makes a difference suggests this. Look for any noise sources within a few feet…

ThreeForm, thanks very much for the reply! And thanks for all the great work on the Mark IV. It looks like a genuine contribution to the field of EEG research -- that's the reason for our enthusiasm for finding a way to build it. I appreciate you…

I recently inquired about purchasing electrode holders outside of the diy kits to complete a set of 19 electrodes needed for a standard QEEG. The answer was "Right now, we are not offering the electrodes for sale individually, but it is something t…

I also have a project waiting for the Ganglion programming tutorial, so please keep it high on the priority list. Thanks, Michael
-
Could you tell me the head size for this kit? Thanks, Michael

I'm happy to report that the zadig driver install and the CSR dongle solved the Windows 10 issue. OpenBCI_GUI is running smoothly. Thanks for the excellent zadig instructions. I have no clue as to why the internal BLE hardware is non-functional o…

@pushtheworld I can appreciate the challenges of being a team of of one -- so am I. And I'm working with limited resources. Solutions I've seen from openBCI such as buying a new computer are unrealistic. IMHO, BT LTE is was not a good design dec…

@wjcroft I'm running on a 2-year-old Thinkpad T540p. The LMP version for its native BT hardware shows BT 4.0 compatibility (LMP version 6.1280). Device manager shows it working properly. I originally tested the openBCI_GUI without the BLE dongle…
