How to build an open source alternative to the g.tec medical multi-purpose headset with 16 EEG channels for around 2 0000 USD – PETER GAMMA (Director & Physiologist), MEDITATION RESEARCH INSTITUTE SWITZERLAND (MRIS)

This device which 32 EEG channels is available from g.tec for around 50 000 USD:

Scientists such as BCI developer Ildar Rakhmatulin at Imperial College London & machine learning researcher at Heriot-Watt University who build low cost EEG devices which have issues are a clear sign that EEG devices which are built on the old architecture which is not based on InfluxDB has become to the end of line.

It seems not possible anymore to make money out of those EEG devices which are not based on InfluxDB:

Peter Gamma, Director of the Meditation Research Institute Switzerland (MRIS) is on a Budget

And this makes those devices interesting for open source developers. After reviewing such EEG these devices for many years, I came to the conclusion it is currently not worth to go beond 16-channel EEG System based on OpenBCI:

There is a Wifi shield available on Aliexpress which has issues, but it sould be possible to repair it. So we could build a 16 channel EEG system with wifi transmission for around 3 000 USD.
