This paper shows that it is possible to build a 32 channel EEG device from the ADS1299 chip:
Summary of the conclusion of the paper:
“This paper presents an open-source, high-precision, multi-
channel EEG acquisition tool system named BEATS. It
achieves similar features with other state-of-the-art implementations including cost-effective, portable, etc.
BEATS implements 32-channelEEG acquisition at a sampling rate of 4k Hz. It has a higher
channel number for the same sampling rate or a higher
sampling rate for the same channel number and can support
more channel numbers if a lower sampling rate is configured.
Third, as an open-source system, BEATS provides
complete design files and materials, which is capable of being
quickly and easily reproduced.
Besides, BEATS implements a complete system from hard-
ware to software, including PCBs used easy-to-access ma-
terials and a plug-in structure, a user-friendly GUI and a
wireless data transmission, which make it can be easily set
up. Meanwhile, it can also be able to acquire ECG, EOG,
EMG, and other signals. Due to these exceptional properties
of BEATS, it can be widely used in various research scenarios,
and is ideal for long-term daily monitoring.

According to the little experience of Peter Gamma from www.petergamma.org, many of the products listed here are still full of issues which need to be resolved. If you do stock market speculation and scalping with those, you will loose Peter Gamma from www.petergamma.org as a buyer of these products and as a reviewer. Is this not risky? Will you not loose a majority of your costumers as well?
And is it not so, that society in general does not accept stock market speculation and scalping with products as those which are listed here? And will you not be politically incapable of finding a majority of the voters if you do stock market speculation and scalping with these products?
And as a consequence will you not be condemned and punished by a political referendum soon? Especially if you do this to a Swiss, since are not majority of Swiss against stock market speculations and scalping with people on a budget? And people in Switzerland are known for a lot of political referendums, since we have direct democracy in this country.
And Peter Gamma from www.petergamma.org will fight up to the European Court of Human Rights against people who do stock market speculation and scalping with the products which are mentioned on www.petergamma.org. And if they do not have yet the legal basis there to do so, he will fight for it.
What is a scalping?
Scalping is a trading strategy in which an investor buys and sells a single asset multiple times throughout the day. The goal of a scalper is to make a small profit over a large number of small trades, rather than a huge profit on each individual trade.
What is a scalper?
A scalper is someone who buys something and resells it at a price far above the initial cost. For instance some says: “He got theater tickets through a scalper”: Someone who buys tickets to an event in order to resell them at a profit. And is it not also scalping if you take reviews from this site to make out of it a new product offer, and sell it for a higher price? We doubt that you will be successful with it. Since Peter Gamma will review your product and will user not come back to www.petergamma.org after that?
