Ben and William, Thank you! I just wanted to be sure. Wow - don't I feel like a dolt! All this time I thought it was spelled the other way. I've corrected my website. Sorry about that! If there is any way for you to edit the incorrec…

William, Thank you! I have updated my website with a script to convert from when we are using the Bluetooth data capture method. I appreciate your knowledge and guidance, could I ask you to review it for me and advise as per accuracy? The sectio…

Hi, In digging around on the forums, I found a link that helps describe how to handle the RAW files generated when using the Daisy board: Our 16 channel system allows for control of individual settings for all 16 channels, and data is retrieved f…

Hi, I upgraded to the latest version, and was presented with a Java error when I ran the HUB. So I changed the HUB version to OpenBCIHub-v1.4.2-win-x64-64bit - but and it ran, but the GUI would not open - it stalls when you select Cyton and show…

Hi, Thank you for the insight! I have continued my research and continue to learn the mathematics required using MATLAB. I am trying to determine the frequencies naturally generated by the brain. You can review my progress here: http://generalf…

@yeyem, Sorry for my late response. I would from the point of view that they work better with medium length hair. They worked well in my usage thus far! I've had absolutely no issues with them at all. I'll buy them again. But the coating does …

Hi, I updated the documentation tonight to include signal conditioning. When you first start recording, the hardware 'settles', causing spurious signals - which are also recorded. I wrote code to allow the viewing of the first few samples, such th…

Thanks @pushtheworld I appreciate the compliment.

Hi, I purchased MATLAB (Home version), and have been working to interpret the signals generated by my Cyton, Daisy Board, and Mark IV Headset. Because I am new to this technology, and was struggling to 'get going', I thought I would help out anyon…

Hi, It would seem that I am getting an output. During the upgrade to 3.2.0, the location where the files are being saved changed to a new folder (C:\Program Files\OpenBCI_GUI\SavedData). I was unaware of this. I suggest you put information in …

@wjcroft Thanks for the info. I'll monitor their life-cycle and post back for future reference. I will also advise @kzurn. Don

@pushtheworld Sorry, I have not been working on this. I have been focusing on MATLAB. I just noticed, however, that I did not perform the step below: Enter the new OpenBCIHub folder and right click on the executable -> properties -> comp…

@pushtheworld Thanks for the heads up on these 5mm FRI Dry Electrodes - they are FANTASTIC! Great signal! I don't have to tighten them as much. Great feel! I am 100% satisfied! Wonder why OpenBCI does not just supply them? Thanks, Don
-
Sorry? I thought I could just replace them directly?
-
I bought them, installed them, but have been focusing on getting my filter in MATLAB to work, so I have yet to try them out. I can see that they would be more comfortable, as per their smoother ends. And they are cheap! I hope to try them out nex…

Hi @pushtheworld @wjcroft, A question in general - if EMF noise plays a significant factor in this - would we benefit from wearing grounding straps? The body is a giant antenna, so if we were to ground ourselves via a strap, could that not elimin…

Hi @pushtheworld How do I do that? I'd like to help but don't know how. Thanks, Don

Hi @tmorrill, I just wanted something that basically detected signals - nothing too precise - I wanted to keep costs reasonable. I picked up one of these for around $40.00 CDN: https://www.ebay.com/itm/1x-IBQ102-Portable-Hand-held-Frequency-Coun…

Hi, Another question - could I pick up a Ganglion, hook it up in parallel using electrodes to cover Fpz, Cz, Oz, and Fp1? I would wire Fp1 in parallel between the Cyton and Ganglion (giving the two a common reference)? Or would that electrically …

Hi, I found them in the GITHUB download, but you might want to fix the hyperlink. Thanks, Don

Hi, I was able to get it working for Raw EEG. I introduced a Channel Selector for 9:16, then introduced a Signal Merger and took the outputs of the Channel Selectors to it, with the output going to the Signal Display. Of course I am missing the F…

Hi, I posted this issue under the Software forum, here. Thanks, Don

Hi William, I downloaded the OpenVibe software (1.3.0), and followed the instructions on the 3rd Party Software > OpenVibe web page on the OpenBCI website. When I run the filter in the designer, I only see 8 channels, even though I configured …

Awesome! I just bought them now. Thanks!
-
@pushtheworld Thanks! But I am new to this, so I am unsure - how do these mate with / replace the ones provided with the Ultra-cortex Mark IV? Do they just swap out?
-
Update - 45 minutes into a test before it finally Railed on 5! And I was up, moving around, talking on a phone during the test. And I did not have the gains reduced at all. I will do this test again tomorrow to see if it is consistent. Thanks
-
@pushtheworld No - I did not try them. But for a $1.00 a piece I certainly will! Where can I find them? Thanks!

William, Good catch! It is marketed as a Frequency Counter, but truly it is in fact an RF Meter. Sorry for not being more clear. I was amazed at all of the RF generated by hydro lines hidden in the walls of my apartment. I found my stereo gen…

William, I tried tightening the ear clips, but today noticed no difference. It continued to rail. No, I think this unit is better. It takes longer to rail, and now seems to rail on different electrodes. It does not always rail on 9 non-stop. I…

Hi, I used a Frequency Counter that I purchased for $30 off the Internet and swept my apartment to find the best location. Funny bit was - it was right where I was already sitting! Thanks, Don
