As you can see we have many devices based on the ADS1299:
But why do we still not have an affordable alternative to products from www.openbci.com which has a community? And why do we not have a 32 channel EEG device based on the ADS1299 on the market? We have:
- the 32 channel channel system based on the ADS1299 Ti demo kit
- the 32 channel system based on on HackEEG 32
- the 32 channel system based on BEATS
We have 3 architectures now for 32 channel open source systems, or at least partly open source systems. But none of them seem to be a success so that it would have a community. The next architecture which is interesting for us personally is PiEEG. If PiEEG stays on the market and is not just another demo such a HackEEG and BEATS, and will be unavailable again, soon, the community could migrate from products from www.openbci.com which are expensive for what they offer, and are hardly developed further, and OpenBCI modules sold on eBay and Aliexpress which have isses, from HackEEG and BEATS which are unavailable, to PiEEG which is interesting for the future, if it is tested and proofs that it is possible to run it free from EEG noise, in whatever combination with a single board computer or microcontroller, and if it is developed further.
To cut it short: products up to the g.tec medical mult-purpose headset for 50 000 USD can either be replaced by 4 daisy chain PiEEG modules for 920 USD. Or someone will bring a printed circuit board on the market with 32 TGAM modules which can be used with InfluxDB for 700 USD to replace the g.tec medical headset for 50 000 USD. According to our own little experience this will happen only slowly, but we are convinced that this will happen. And it is the choice of the EEG device developers what exactly will happen.
