Ok, thank you... 1. Is this what you mean - see attached w/ circled 1 next to it. 2. For the time being I was going to change your Beta weight to 0 from the .65 you had. I may play with this later (try to suppress Beta and Alpha both) but for now…

William: quick question about your BrainBay example you gave above (located here: https://sites.google.com/site/biofeedbackpages/brainbay-openbci/neurofeedback) If I was to use 2 or more channels/electrodes to get the data for better "average" ac…

Aaahhh... Interesting. Good to know! Thank you.
-
Cool! Thanks, William. That helps a lot. I tried Cz location and the waves seem to appear more defined there, plus - the amplitude is greater. I see that this is a better location, but did not quite understand the adhd frontal slowing reference…
-
Awesome! Thanks. Couple of followups regarding hardware setup: * If I was to use just one channel for this, maximum two channels, can I use one earclip vs. two? * If I was to do the absolute minimum setup, can I use one electrode on one side…

Ok, thanks. Yeah, that looks like the way to go. I was just wondering about Focus Widget out of curiosity. Do I understand that Neuromore is free from this (their website): "Licensing the neuromore Studio starts at $3K monthly. neuromore also of…

Thanks, William. I am afraid I do not know how to read these, though, as I am not familial with these programming languages.

I went through this https://docs.openbci.com/Software/OpenBCISoftware/GUIWidgets/#focus-widget and was wondering: * What are the units of these numbers (0.0072, .1974, .0004, etc.) - likely percengtages, from what I can tell. But percentages …
-
Aha. Ok, got it. Thank you.
-
Ah, got it to work! Thanks, William.

Thanks, William. I have the Ganglion board and tried BrainFlow (loaded from here: https://github.com/ChrisVeigl/BrainBay/releases, just loaded and installed "Setup_BrainBay.exe") , but for some reasons get error following instructions in the link…
-
I see. Thank you.
-
Thanks again, William. I looked through everything you posted. My knowledge of programming is rather limited, but from what I can see, the cleanest way to do what I am after is to make a copy of the Focus Widget and then tweak the source code sl…

Great! Thanks, William.
-
Ok, thanks. I tried pressing electrodes harder against skin, but the results are about the same. What amplitude would you expect with wet electrodes you mentioned?

Hi William, I was waiting for some hadware from the main office, so just restarted experimenting. While far from an EMF source, I get the following output. It changes, of course, up and down a bit, but that's about the average. Next image is t…
-
Thanks, William! I'll take a look at the Excel examples in depth a bit later tomorrow. For now, though, what unit of measurement is used for data in columns B ("EXG Channel 0") and C ("EXG Channel 1") of the spreasheet image I posted? Also, a…

Thank you, William, for the links. My tasks are fairly simple at this point, however, and thus, I would like to see if I can do what I am after without learning a programming language. It seems that I should be able to calculate the numeric inpu…

Ok, thanks, William. Did some experimenting and seems to be working now.
-
Yes, I did. Thanks, William.
-
I figured it out!! Or most of it, I think. Lol! * It's the EMF from my laptop and electricity in the house! I did an experiment where had the sensors and the board close to the laptop, and then further and further away. The background rose…
-
Thank you, William. I read throught the material you sent and followed to the T. Still the same result, though. One thing I noticed is that the background noise (as you have named it, I believe) is very large in my output vs. what's in the exam…
-
Hi William, here are answers one by one: * Are you following the steps in the tutorial link I gave? - Yes, I am. * Do you have cup electrodes and paste to contrast how that works? - I got this kit, which as far as I can tell does not in…
-
Thanks on this one as well, William. You said "Valid EEG is mainly below 100 microvolts. So your Band Power graph is just getting swamped. Are you following the steps in this tutorial?" I found this one: Just looked at one you sent and do no…

Thanks, William. One of the turorials I saw online using Ganglion said to run impedance check and make sure the lights are green: * at 8:25 mark - see green letters at bottom of video). I did email customer service for clarification as…
