thank you for the post, friend
wow that is amazing man , would like to read more of your series.
Thank you for the nice comment. I will surely come up with something nice I know for sure. But I think my posts are getting less visible here. steemit will become mature with time I guess. :)
The tags you are using will have a lot of effect on visibility . you are in good care with steemstem , just a matter of time though , also keep an eye on posting time (UTC)
What is the best time?
Nice build, and interesting post. Have you tried to filter the 50Hz? It looks like you have plenty of signal, so it is not necessary. I am interested as using battery power, and still getting noise from the utility implies you may need more than a Faraday Cage ...or a really big one you can walk into. If you just shield the circuit, you will still have your body and the external wires picking up the noise.
It looks like you are already using differential inputs and have plenty of common mode rejection. I have seen some odd cases where single ended worked better, but if the energy is induced, as it appears to be, I would think the way you have it is best. At any rate, as mentioned your signal to noise looks nice, so keep on experimenting.
It has been a while but I have done experiments requiring a Faraday cage big enough to walk into and perform experiments without any external noise :-) --3D
I was not satisfied by my output. I was lazy too. And I was doing electronics after many years. I am thankful for your comments. At certain points I got better outputs. I noticed that even the place I am setting up my experiment matters. May be I should talk to you in discord. 😃

Thank you @bitgeek . Can you tell me how you pulled out the data. I am interested in knowing.
A great article ! I am writing an article on brain waves and eeg. If you want to review the link here; @emrearar
Who knows, maybe we can do a joint project. :)
Cool. I am interested in brain waves are EEG. If you are in discord we can talk there. :)

STOPWill share this with my son, he is in the first year of electronics and communication engineering.
Let me suggest something. Ask him to contribute to #steemSTEM . We need quality contributors and active members. steemit is not very popular in India. We need more awareness progammes. I feel personally that when students contribute actively to communities like #steemSTEM it is a win-win scenario. They get incentives, community gets strengthened and his learning process will be more active.
yes and I will show this to him. He has been writing an article as per my suggestion but did not complete it because of his internal exams. It is over today, so will ask him to do it. Thank you so much
