So, I assembled it, updated the firmware, put it on and... How do I validate the hardware “works” correct? for example, with EEG you’d shut your eyes and see immediate raise in alpha waves. and in HEG ?
Hey Oori,Glad you received yours.What you want to see is a fairly stable ratio so that when you breath deeply it has clear correlation. The ratio in general for me is around 0.4 to 1.4 depending on where it sits on my head. There are also sample data and a charting applet in my repository you can use to compare your data. That should be enough to validate. Noise can come from power sources e.g. if your laptop is charging, and that is the major confounder of data at the moment.
