Low-end EEG kits exist.[1] Probably easier to start with that.

My favorite toy in this space was Nekomimi in 2012 - cosplay cat ears connected to an EEG sensor.[2] It sensed "resting", "active", and "surprised". I saw some girls wearing these at a convention. Someone called out the name of one of them, and her ears popped up. Only the one, not the others.

It was a good idea, but too bulky. 4 AAA batteries plus huge ears. Someone should do that again, more compactly.

Whoa the Nekomimi looks super fun: https://www.huffpost.com/entry/necomimi-mind-controlled-cat-...

The MindWave Mobile seems far more convenient than a dissected Mindflex. Thanks for sharing the link—I may need to get one myself. Achieving consistent electrode placement was certainly a challenge when I was working on this project.

I hadn't come across the Nekomimi yet but it seems as though Neurosky has figured out how to manufacture relatively inexpensive EEG consumer devices. Further, the Mindwave mobile seems to get 8 hours of run time off a single AAA. I would suspect a more compact implementation of the Nekomimi is quite achievable.
