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.

If anyone is interested, I'm actually in the process of launching a similar board. Much lower noise (by about 5x, custom AFE) but 4 simultaneous-sampling channels.

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.
