Good signal quality for ECG, EOG, & EMG with “BEATS”, Pi ADS1299 EEG shields on a Pi 4

BEATS is an open-source high-precision, 32 channle multi-channel EEG data acquisition system:

The above paper shows Electrocardiogram (ECG), Electrooculogram (EOG) and EMG signals which where aquired with the device. BEATS is capable of collecting 32-channel EEG signals at a guaranteed sampling rate of 4k Hz and uses wireless transmission:

The paper shows also a short EEG recording with eyes open and closed. In contrast, the example we have with PiEEG and different single board computers look noisier:

The paper with the “BEATS” device shows that it is possible to build a device with a Raspberry Pi 4 and ADS1299 EEG shields which delivers a good signal quality. The paper shows data of 24 channel EEG experiments, but we do not have data which show the 24 EEG traces of the device so that we can say something about the quality of the EEG signal. The ECG, MEG and EOG signal shows only one single track. Therefore we do not know how good the quality of the signal is when the device records 32 channel EEG channels in parallel. So we have not no final answer if the Raspberry Pi 4 with the EEG shields which are shown here are suitable for high-quality and research and medical grade EEG applications. The specifications of the ADS1299 makes the chip suitable for research and medical grade applications. In daisy chain mode with up to 97 chips in parallel.

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?
