For Peter Gamma from www.petergamma.org
the following devices are still interesting:
OpenBCI modules imported directly from China:
Products bought in the U.S.A. are often associated with high shipping costs an import taxes for Swiss costumers. And after studying the OpenBCI architecture for many years, Peter Gamma from www.petergamma.org supposes that he is able to repair those modules. This requires soldering for the WIFI shield, eventually replacing the connector between OpenBCI Cyton and the WIFI shield, sending back modules to the sellers, etc. The OpenBCI architecture is on the market since about 10 years, and it has been used and tested intensively, and offers many software options.
PiEEG
Is new on the market. We think it is currently mainly a product for developers. OpenBCI has been used by countless users, but not PiEEG. It seems not to sell at the moment, which is an evidence that it has issues. But should it be possible to resolve these issues, it would be a new and interesting platform. It is highly desirable to have tests about the quality of the EEG signal of PiEEG. And if these signals have issues for instance with noise, to have instructions how these issues can be resolved.
Physiological multi-sensor devices based on InfluxDB

The ADS1299 EEG chip from Texas Instruments hasn’t been cloned up to the present day. And these products seem to be strongly controlled. Only very view product developers use it, as for instance A.J. Keller from Neurosity:
And it seems to be difficult to build your own device on this architecture without a special contract with sellers who want to profit from you, which make these products less interesting.
An alternative are product based on InfluxDB:
The architecture is more complicated. But there we do not have to problem with stock market speculations and scalping as with ADS1299 EEG chip products. Products from www.openbci.com do not have these issues, but we think they are expensive and remain expensive. We suppose that EEG products up to about 50 000 violate competition laws in the US, EU, UK, China, Canada & Switzerland, altough this is difficult to proof. But if we compare these products with the development of other electonic components in recent years, we think these EEG devices are little competitive and only view buy these EEG devices.

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?
