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...

Googled:

https://en.wikipedia.org/wiki/Comparison_of_consumer_brain%E...

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.

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.

Have you played with Ti's EEG ADCs out of interest, they seem reasonably affordable.

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].

FYI, the OpenBCI boards are based on the ADS1299 from TI. They are essentially an Arduino wrapper for the ADS1299.

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).

It wouldn't make much of a difference though if you are already wearing VR.

A partnership with NewEra or some other cap manufacturer would be awesome, allowing the tech to be woven into everyday life.

There's IBVA also (Mac support)
