This gave me a good laugh! Perhaps a better title would have been "Tearing Apart a Toy to Obtain EEG Data". Regardless, I am glad you found it interesting.

This is great, thanks for sharing. I think I will give a multichannel headset a try and attempt to train some models that map neural activity to cursor movements.

I came across this article today: https://medium.com/@kevinjycui/of-mice-and-mind-creating-a-s...

It sounds as if this individual had some success with the Emotiv INSIGHT (5 Channel) but the data quality was a limiting factor in creating an application usable for everyday activity.

Did you have any specific gripes with the Mind Monitor app? The visualizations seem nice, but it would be interesting to see a feature that allows synchronization with other data sources. (e.g. connecting a keyboard to capture both neural activity and keystrokes simultaneously) That said, this might not be worth the effort. For me, obtaining high-quality data was a challenge, which I suspect is a common limitation of non-invasive electrodes.

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.

It seems as if the Overleaf autocorrect has a mind of its own occasionally! Or, that's my perception at least.

I will also need to shoot NeuroSky a message to see if I can get my hands on one of their dev kits. This recent venture into decoding EEG data was fascinating and I would love to see how far I could take it with non-invasive electrodes.

That's awesome! Did you attach the electrodes to the head or somewhere on your arm? I would also be very interested to know how you decoded the electrode data.

On another note, I found it pretty surprising that it's possible to get even remotely accurate data from the Mindflex. As a child, I remember wholeheartedly believing it was real. But, only when I won.

I am very interested to hear if anyone has any recommendations on the next steps for this project. It's been a fun one!
