The muse S breaks too, although I admit it is cheaper. OpenBCI has cheaper products as well, ones that support stacking together and are written in open source software. There are newer products sold now; many kickstarters etc have been making devices. There is also an older community device called the openeeg supported a little by groups I engage a little bit already. The openeeg looks like it hasn't had activity in some time; I haven't found where it is happening, but could ask the connections I slightly have. My Muse S is _turned off_. I do not use it. Putting it on at all has been my step, like the wim hof showers for going outside. I reverse engineered its protocol once. decompiling the commercial binary, so I could make a logger more robust than what is sold. After reversing its protocol, I discovered that it was public but the page had gone down. I had worked with the public protocol in the past and forgotten this. One of the communities I am in is a meshing of researchers and hackers. The people on the chat are very, very experienced, many of them with graduate degrees, and happy and excited to work with people who are new. I never go on, and am scared to internally. I started a conversation with one but waited so long to reply that what they said had left the chat history by the time I got back. That was a few years ago. The chat is the neurotechx chat. It used to be easy to find, then it became hidden deep inside some forms or websites somewhere. Not sure how it is now. They were stuggling to effectively log their slack channel; needs a bridge to a logged community. It often has crucial research streaming by that then gets lost. This is true of other research communities, too.
