PiEEG developer ldar Rakhmatulin shows us how to build our own a brain-computer interface (ironbci DIY) in PCBWAY:
But is PCBWAY also member of a marketing trust who wants to maximize profits out of us?
`
Which developer at the university choose such a pathway? His developments increase the value of the products, but the one who profits is not him, but the one who offers products to him, who increases prizes for those, as soon as the value of the product the developer at the university level increases?
We have experienced a such phenomeon in the example of the LattePanda Delta. It was sold for 200 USD from Dfrobot. But as soon as we showed interest in this product at Digitec Switzerland, it was pulled from the shop there, and replaced by a new offer which now costed 350 USD. We suppose that a positive feedback about this product was the cause for this. In other shops in Zürich it costed still 200 USD, but especially for us at Digitec Switzerland the prize was increased for 150 USD, and we are forced to buy it elsewhere, if we are not ready to pay the extra 150 USD.
Will Flavio Frohlich or the students of the Swiss Federal Institute of Technology of Zurich ever buy such products from sellers who treat their costumers in this way?
If all of this is true, does it make any sense for Flavio Frohlich or the students of the Swiss Federal Institute of Technology of Zurich to develop open source hardware based on the ADS1299 EEG chip from Texas Instruments?
Whe are physiologists, and not experts as Flavio Frohlich in this field. But we suppose it does not make any sense. If it would make sense we would know of such developments. We are interested in such products since several years, be know only of one developement performed at the Swiss Federal Institute of Technology in Zurich, which used products from www.OpenBCI.com. But would these developers still choose these products after if they have read our journal?
If so, we do we not all choose right away this solution?
And if so, why does not also Irene Vigué-Guix choose this solution right away as well?
Since she received products from www.OpenBCI.com for free in exchange for a review?
Our hypothesis is this, products based on the ADS1299 EEG chip from Texas Instruments do only make sense for Flavio Frohlich and the Swiss Federal Institute of Technology of Zurich if it is their hobby project. Or if it is a student project without any further goal. But for really serious developments at the level of Flavio Frohlich it does not make any sense.
As far as we know, Flavio Frohlich was looking for low-cost hiqh-quality EEG devices. Www.OpenBCI.com always claims that their products are low-cost hiqh-quality. We do not agree. We found OpenBCI products cheaper. But all of these seem to be controlled by a marketing software to maximize profit out of it. And we are asking, is behind all of these developers one company hiding, and that is Texas Instruments?
The ADS1299 EEG chip from Texas Instruments has no real competitor. But we ask ourselves, if this chip is really competitive for Swiss developers as we are. Swiss who are known to be extremely competitive? We always fail to find a low-cost high-quality EEG device which are based on the ADS1299 EEG chip from Texas Instruments which fit’s our needs. Is this so, because this chip is strongly controlled by Texas Instruments, and what can be done with it is coordinated world-wide? And for which developers at the university level are EEG device which are based on the ADS1299 EEG chip from Texas Instruments interesting? For Irene Vigué-Guix who receives products from www.OpenBCI.com for free in exchange for a review? But are the products with the ADS1299 EEG chip still interesting for developers at level of the Swiss Federal Institute of Technology in Zurich? All these questions are open.
