The OpenBCI architecture is limited to 16 channels:
As we have discussed previously, this problem could be solved by an alternative architecture, as for instance the wearable EEG system with an ADS1299 & a Raspberry Pi Pi RP2040:
This device does not offer a direct connection between different boards with the EEG chip which would be necessary. Only over the usb-c connection it would eventually be possible.
This architecture with the Raspberry Pi RP2040 looks similar to OpenBCI Cyton. The RP2040 does draw as far as we know much more power than the microcrontroller of OpenBCI Cyton. OpenBCI Cyton has a noise-free EEG signal. But the wearable EEG system with an ADS1299 & a Pi RP2040 has not yet shown any data. The reason could be that the software is missing.
Unfortunately, this device is not an open source project. It was developed by Aditya Mukherjee from India i around 1-2 months. The device will start selling once the firmware is tested. You can email me at aditya@mukherjee.tech with your requirements. The device took 1 month for design from his side and the fabricator took 1 more month for fabrication and assembly. It is a great new device, but since it is not open source it is not suitable as an OpenBCI successor.
PiEEG has not yet shown EEG signals of the quality of OpenBCI Cyton. This could be caused by noise from the single board computer. The SBCs used by PiEEG are quiet powerful, which is not urgently necessary. Eventually the situation with PiEEG, a Raspberry Pi zero and a cable becomes better, so that it becomes a real OpenBCI Cyton competitor, which it is not yet at the present moment.

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?
