Is it possible to get Muse to store any data, or must it be tethered to my PC to record data?
What kind of data do you want to record? If you talk about eeg, fft, etc then PC is a must.
Is there any internal memory storage that could be used to store some EEG data?
The existing hardware has the ability for an accessory like that to be added in the future, the usb ports can output data to a custom storage device, but it’s not available yet and I’m not sure where it’s at in the long term plans.
