Great project. Put up a small issue on Github for a couple of the links in the article.

A quick look over the other links looks like they're okay, follow them instead for the moment.

Cool. What are useful aaplications of diy EEG?
Could do more accurate but less comfortable sleep tracking
tl;dr it uses
Texas Instruments ADS1299 (24-bit, 8-channel) analog-digital converter
There is no way to do what that chip does for less, maybe 7$ less but then not as good. They have priced it perfectly and I hate them for it.
