OpenBCI

• constist of a a the PIC32MX250F128B microcontroller
• and a ADS1299 EEG chip
• the PIC32MX250F128B is a 32 bit Microcontroller with 32-bit RISC CPU with 0.5 mA/MHz current consumption
• it has up to to 128KB Flash memory
• The OpenBCI Cyton and the PIC32MX250F128B Arduino compatible, and teh PIC32MX250F128B is cheaper than an Arduino
• OpenBCI Cyton connects over a Bluetooth to a PC, but also WIFI and cable connections are possible

PiEEG

• does not have a Microcontroller
• but only a ADS1299 EEG chip
• the PiEEG board is connected over a 40 pin GPIO connector to a Raspberry Pi.
• If we compare the signals of PiEEG to OpenBCI, the signals of PiEEG looks noiser:

EEG signal comparison o OpenBCI Cyton, PiEEG, JNEEG & ardEEG

• This is eventually caused by the single board computer.
• PiEEG is connected over GPIO pins to a Raspberry Pi.
• The Emotiv Epoc Flex 32 is connected over a wired only connection to a PC as well.
• EMOTIV recommends using a USB extension cable and positioning the receiver away from other devices.

EEG headsets we found which use wired only connectivity: the Neurofax EEG-1200 & the Emotiv EPOC Flex 32

• But we do not know if the noise in the PiEEG signal can be reduced through adaptions as described here:

Why has the PiEEG signal to be filtered when using a Raspberry Pi 5?

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?
