We have but OpenBCI Cyton back to your frontpage – here is why:
OpenBCI made in China
We have reviewed a lot about OpenBCI in recent years. And we now came to the conclusion that especially OpenBCI made in China is worth testing, as described here:
Over the last several years, we hat to digest a lot of information. But if we look where we stand now, we see that we have found several very skilled soft- and hardware developers which resolved many issues which for instance the OpenBCI WIFI shield has. And we think it is worth testing if we can resolve these issues. The result would be a 16 channel EEG device with WIFI which might be interesting also for research applications:
PiEEG
And also as far as PiEEG is concerned, a lot of work has been done. It is available now, it can be tested. There is a forum for discussion:
And now we stand with PiEEG where we stood with OpenBCI made in China several years ago. It was a new product which hardly anyone seemed to buy, which OpenBCI made in China still is. But after several years, we are at the point now, that we have at least written an updated a documentation about the issues of OpenBCI made in China. And hopefully in a view years from now, PiEEG is at the point where OpenBCI made in China is today. And if we get PiEEG to work, we think it would be relatively easy to overcome the 16 channel limit of OpenBCI:

Multi channel EEG devices based on InfluxDB
Home Assistant is available since several years, and it is a multi-channel device which is based on InfluxDB. But why do we not have such devices for physiological sensors? If we look back at the last view years, we see that the development of EEG devices is quiet slow. Devices up to around 50 000 USD such as the g.tec medical multi-purpose headset are not yet based on InfluxDB. And it is quiet a big step for a physiologist like Peter Gamma from www.petergamma.org to change to a platform which is based on InfluxDB. We hardy did find any such projects after our first search. A rare example is this conference paper:
https://ieeexplore.ieee.org/abstract/document/9087877
So we stay for the time being with the devices listed here and see what we can do with those, and do not start any new developments based on InfluxDB.
