To develop a EEG device based on OpenBCI and InfluxDB would require a hardware change. All channels need to sampled at exactly the same time. If not certain parameters such as phase, coherence, etc. Are not available. But has this knowledge been implemented in the paper of Indonesian scientists in the paper:

«Development of Electroencephalography (EEG) Data Acquisition System based on FPGA PYNQ»

We haven t read the paper it in detail yet. But to sample all channels of PiEEG shields from different Pi s at exactly the same time, is this not easier to implement than with a single board computer asn 4 TI ADS1299EEG-FE boards as it has been done in the above paper?

One reply on “To build a low-cost high-quality 32 channel EEG headset from four PiEEG’s easier than from 4 TI ADS1299EEG-FE boards (part II)?”
