Does anyone know how the OpenBCI headset compares to something like the Emotiv EPOC headset? I'm just starting to get into this stuff and looking to buy a headset for tinkering, but not sure which one to start with...
Most of the consumer stuff is crap… only system I'd suggest is with openephys, but at this point youd have to buy the cap/electrodes separately putting you at a $3-5k range for 32 electrode setup, which I have to say is a lot better than the $100k+ systems researchers are used to and like to use for a reason.
No I haven't, but here are the datasheets for the parts used in the OpenEphys acquisition board[0], I'm sure they could be swapped out for other parts given anyone's particular constraints. To assemble from scratch the acq board, they are saying it will cost about $1k[1].
An excerpt from the forum post seems to point out that openbci uses the most advanced amp:
Regarding data quality, I don't know of any other consumer
grade equipment that has the research / commercial grade amp
we are using, the TI ADS1299. 24 bit samples, programmable
gain and sample rate, delta-sigma ADC design, sensor location
flexibility, on-board programmability. Much of the consumer gear
has fixed 10-20 locations and only a few sensors, closed source approach, etc.
Honestly, I can't imagine myself wearing such a gigantic and ugly headset.
However, I can't wait until this technology is miniaturized and mass commercialized for a few generations. Hopefully, it doesn't trip up like Google Glass did (which is another important technology that ties in with this kind of thing).
