Thanks for the suggestion of getting a meter. Do you know if these meters can tell me what location the EMF is coming from and what frequencies they are at? Without this, it will be hard to make use of it other than to conclude that there is or is n…

It will be pretty inconvenient for me to find another location since I have roommates and there isn't a lot of space. Is there any additional filtering I can try? How do I know where the EMF fields are coming from? Is there some kind of handheld dev…

Hi William, I tried your suggestions to reduce 1 Hz noise: I turned off all lights so that the only light source was daylight. I moved my board farther from the wall outlet. And I unplugged my PC's charger in case that may have some effect. Her…

This Ganglion has never worked for me yet, so it might just be broken. I should contact customer service on this. I have tried recording from the temporal area but did not see any sensible signal. I will have to try the parietal and occipital region…

Yes I've read your comments. I tried swapping the ear clip connections between REF and D_G. I got the same impedance results. After reading through the Ganglion Specs document, it is my understanding that the top and bottom pins corresponding to REF…

My curiosity on this matter initially started when I realized I wasn't getting any EEG signal, only noise. I'm attempting to share a screenshot of my simple setup as described previously.

Hi William, Thank you for your response. Yes, I'd be happy to share some values I got: FP1 channel impedance = 57.5 kOhm and reference impedance = 28.5 kOhm. I had some floating pins on the other channels giving impedance readings around 600 kOhm…
