Peter Gamma from www.petergamma.org reviewed since several years EEG devices. A mantra which was often heard was that Texas Instruments is not able to offer EEG devices below the costs of OpenBCI.
After we reviewed:
- we found HackEEG
- PiEEG
- OpenBCI modules from China
But all of these EEG devices are faulty. And not a single one of these products is in the slightest way a competition to products from for instance www.openbci.com.
It seems as sellers as these TI advisers here:
strongly control these devices. From OpenBCI modules from China

up to the g.tec multi-purpose headset.
This strongly reminds us of the crisis of Raspberry Pi. For years, basically no new products came onto the market. And Raspberry Pi CEO Eben Upton advised us to buy their old Raspberry Pi models which they still had on stock.
All of this brings us to the conclusion, that the here mentioned EEG architectures are basically dead.
Peter Gamma from www.petergamma.org

is not an A.J.Keller
who wants to sell an EEG device with a neurotic name. And the longer this situation goes on, and only new crazy EEG devices are developed by crazy people
We will turn towards products based on Influx:

700 USD was the price TI boards with the ADS1299 chip and 32 EEG channels started selling on Aliexpress a view years ago. Until sellers shoot up the price for those to a view thousand dollars. 700 USD are the costs of a 32 channel EEG device which is based on TGAM modules and InfluxDB. Observations like these here let as conclude that EEG device sellers know about this topic since years, that physiological multi-sensor devices which are not based on InfluxDB are basicall dead. And they seem only to make some stock market speculations and scalping with these old architectures, until they finally are replaced by a new and contemporary devices which are based on InfluxDB.
