[Mumps]

hey! sorry to get back late - don't get HN notifications.

OpenBCI is a really solid start! Though, I'd suggest it's too expensive for most people to start tinkering with it. It also has/had some reaaallly basic featuring, like writing out information as txt, instead of any other signal output datatype. But that's all fine! (just unsophisticated)

You can start off [way cheaper](https://www.instructables.com/Mini-Arduino-Portable-EEG-Brai...), and even make an [electrode out of a penny](https://www.youtube.com/watch?v=yglqbxYBC7Q).

Spend some time planning what you want your first project or two to be, and then get the cheapest, lowest-feature thing from there.

If you want to *really* learn some stuff, I'd suggest you focus more time on computationally processing eeg signal (you can get [an insane amount](https://sccn.ucsd.edu/~arno/fam2data/publicly_available_EEG_...) of sample data for free). What you get from hardware yourself will just have the cool-factor of being your own :)

Thanks for the detailed response! I'll look into that!
