Is Cody Rall MD with Techforpsych happy with his brain devices he reviews for at least 10 years?
And is Peter Gamma from www.petergamma.org happy with his Orange Pi 5 & OpenBCI Brain Flow who reviews EEG devices for many years either?
For years I was reviewing EEG devices. And i was turning in circles. These devices seem hardly developed further. On the contrast, for instance building a 3 channel gold Standard ECG device with spirometer has become much more interesting for us personally:
The AD8232 ECG chip, the ADS1115 16 bit A/D converter & an Arduino microcontroller – the building blocks for a multi-channel ECG device for medical & research grade applications
