There are some relatively cheap consumer units out there now I understand. I haven't even looked in a while, the Muse is one that comes to mind but I remember there being other lesser known options with more channels and maybe app driven? BTW my interest is to measure meditation state, to see if I can actually track my brain state to stop at a natural point when I've successfully shifted into a different state, rather than an arbitrary amount of time that sounds good.
hello, I just found this store: https://www.mindtecstore.com/ , If you want yo buy something i recommend you to search in the official website because it will be more cheap
There is an open source project - openbci Should cost less, kind of curious about this tests too, did not had a chance to check it so far
