Open Source Headset Enables New Mind-Controlled Devices (popsci.com)

An anonymous reader writes: "When DARPA funded research into a brain-computer interface, artist and engineer Joel Murphy and his former student Conor Russomanno built a working prototype," reports Popular Science. After a crowdfunding campaign, the team successfully developed an Open Source version -- a $399 headset that can register brain-wave electricity (named Ultracortex), along with a $99 board named Ganglion that can use those signals to control mechanical devices. "We want it to essentially be a Lego kit that you get in the mail, which also just happens to be a brain-computer interface," says Russomanno.
Their web site is already accepting pre-orders, though because both the hardware and software are open source, you can also generate your own headset with a 3D printer. And according to the article, two British students are now using the technology to create an app that issues commands to a smartphone by winking.

      Been done, open source software and hardware plans available, also available ready to play for $399?

      The significance here isn't a high CMRR amplifier, it's a complete brain-computer interface component that's ready to be used as a standard HID like your keyboard or mouse. Well, I don't see the USB port, but some boffin needs to put one on there and re-release the upgraded device. And, that's the point, it's a significant chunk of tech already worked out in a standard, readily available format that a community can form around and extend and improve - like Raspberry Pi or Arduino (that happens to be at the core of this), sure the tech has been available forever, but not in a "community oriented" "developer friendly" package.

      AFAIK these packages tend not to work without many extremely sensitive pickups all over the scalp. Even still from what I understand there is so much interference from facial neurons, etc, that getting a usable signal requires extensive training of both the driver and of the user.

      These are all, of course, issues that will go away with maturity, just like they have been going away with speech recognition, head tracking, gaze following, etc. technologies.

      They are NOT issues that will go away overnight because somebody open-sourced some of the basic technology.

      It is a step in the right direction, though, because Newegg typically only has between 0-2 neural interfaces for sale, and they are generally unreviewed or reputed to be quite poor.

      Yea the important thing is the chip that processes the very low input signals at a very high rate. There are other open-source options and even other more commercial products. But the advantage here is that you get the same chip that are used in medical grade EEG sets that researchers use at Universities that can drop $5k on a single pre-fab headset. The software is largely based on, and compatible with, Arduino. You update the program running on the device with the Arduino IDE. And for USB it comes with a nice bluetooth dongle.
