Since Peter Gamma from www.petergamma.org exists, he fights for affordable EEG devices.

once answered to Peter Gamma on a LabStreamingLayer GITHUB issue: «It is worrying how you always try to build inexpensive EEG devices». This was after Peter wanted to build a cheap multi-channel EEG device based on the TI EEG demo kit:
But Peter Gamma from www.petergamma.org will not stop his fight, altough Chadwick Boulay is worried about it. When Peter started dealing with this topic in the www.openbci.com forum, demos appeared of the g.tec multi-purpose EEG headset with 32 channel plus accessoires for 50 000 USD:
And Robert Oostenveld reviewed the g.tec Unicorn Black for 1 000 USD. Did they wanted to find out, how much money he was ready to spend for EEG devices? More interesting for Peter than the Unicorn Black where Indonesion scientists who have built 32 channel EEG devices based on the ADS1299 EEG Temo kit and a single board computer:
And Peter wanted to build such devices as well:
After Peters posts in the EEVBLOG OpenBCI modules appeared on the market on Aliexpress and eBay, as well as Hack EEG. The modules sold on eBay and Aliexpress where linked to the costs of the electronics components to build such a device based on InfluxDB. This made sense, since we we suppose sooner or later devices will come onto the market which are based on InfluxDB, which do not use the ADS1299 EEG chip from Texas Instruments anymore.
A 32 channel EEG board which used the ADS1299 EEG chip came onto the market on Aliexpress. This 32 channel EEG board started selling for around 700 USD. Also the price of this board was linked to the electronic components based on InfluxDB when it started selling. But after several positive feedbacks of Peter the price was increased to 5 248 USD, for which it is currently still available:

The OpenBCI boards sold on eBay and Aliexpress have issues, we have reported about this topic, but also how they can eventually be resolved.
The OpenBCI Galea is sold for 25 000 USD in the www.openbci.com store. Is this device worth that much?
- The high price seem to be calculated by the number of channels which is 16. This is half the price of the above a g.tec device which has 32 channels. Which sellers who want to sell EEG devices calculate prices in such a simple way?
The Neurosity Crown price was now increased from 900 USD to 1200 USD.
- But the Neurosity crown is built as far as we know basically of an OpenBCI Cyton, a WIFI shield and a Rasbperry Pi zero. Building such a device from PiEEG would be quiet easy and affordable.
PiEEG developer Ildar Rakhmatulin brought several PiEEG devices onto the market recently.
- But also the launch of PiEEG was delayed for one year. PiEEG is a competitor to devices from www.openbci.com. Was this done do make as much money out of www.openbci.com as long as possible?
- But PiEEG seems to have issues. Since if PiEEG would be free from issues, would not Raspberry Pi sellers offer PiEEG as well? But they don’t.
- Peter Gamma from www.petergamma.org made some speculations on his site what could be the issue of PiEEG, and also how they could be resolved.
Then we have the devices based on InfluxDB:
- Such devices eventually could also be built by Peter Gamma from www.petergamma.org, altough we think it is currently still time consuming. This makes devices such as PiEEG still interesting.
So for us personally basically 3 products remain interesting, and these are the following:
But only as long as they remain on the market to for a stable price and remain available. But what happened in recent years was the opposite. As we described previously, we observed insane price increases of EEG products based on the ADS1299 EEG chip from Texas Instruments. Insane in that sense, that no one who really wants to sell EEG devices would do something like that. This is rather killing these devices. And what makes these multi-channel EEG devices sick is InfluxDB, an architecture from which we suppose that it will be an ADS1299 EEG chip killer sooner or later. And who invests a lot of time in an outdated concept?
And who invests time in the development of devices which start selling to an affordable price, but if he builts a 32 channel EEG device from PiEEG, the price for PiEEG will be increased to 5 248 USD? We suppose the 5 248 USD is the price for a 32 channel EEG device from mBrainTain. Do such price increases bring more money to EEG device sellers? This is hard to believe. Since such insane price inreases cause us personally only to change to devices based on InfluxDB, to sooner, the better.
Information for product sellers who do stock market speculation and scalping with products mentioned by Peter Gamma on www.petergamma.org

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?
