Hardware?
Very interesting.
I'm looking for hardware which is able to collect EEG on Ali and there's quite narrow choice - Openbci available but horrifically expensive like $500 no less for very minuscule board(sensors not included).
The only affordable solution for ~$70 (excluding the sensor hats with just sensors without hardware) is some Brainlink or Mindlink a headband with "dry" sensors, i see 2 versions - Lite and ordinary, difference in sensors - Lite with 3 forehead sensors vs Ordinary with 2 forehead and earclip (EEG, ground and reference). Lite don't provide HD raw signal and eSense data. The only caveat they don't support Linux but offering some SDK (www.macrotellect.com/brainlink/sdk). Mostly they selling it for iOS/Android to control different games by mind. Connection protocol: Bluetooth 3, working battery time 180 minutes.
Which to choose? Lite or Ordinary?
