OpenBCI: a new open source brain-computer interface on Kickstarter

OpenBCI: a new open source brain-computer interface on Kickstarter

OpenBCI is firmly believing into open source and spreading culture and knowledge on brain to computer interface. The’ve already launched a good product, but now on kickstarter they started a new campaign (already funded with more than 30 days left!) presenting two more products.

With this campaign we are featuring two new OpenBCI Products, the OpenBCI Ganglion Board & the Ultracortex Mark IV.

The OpenBCI Ganglion is a high-quality, affordable bio-sensing device. On the input side, there are 4 high-impedance differential inputs, a driven ground (DRL), a positive voltage supply (Vdd), and a negative voltage supply (Vss). The inputs can be used as individual differential inputs for measuring EMG or ECG, or they can be individually connected to a reference electrode for measuring EEG.

We are using a Simblee for our on-board microcontroller and wireless connection. Simblee is RF Digital’s next generation Arduino-compatible radio module. It is smaller, cheaper, and more robust than the RFDuino, which we have been using on our OpenBCI 32bit Boards and USB Dongles. The new Simblee provides user programmable flash, 29 GPIO pins, and the ability to update software over the air (OTA). Every Ganglion will be pre-programmed with versatile firmware so you can get started sensing your body right out of the box. We will also break-out up to 20 of the GPIOs for you to hack with.


The Ultracortex Mark IV is the next edition of the Ultracortex—a comfortable, adjustable, and 3D-printable EEG headset, compatible with all of the OpenBCI boards. The Ultracortex’s revolutionary design uses dry EEG sensors and takes less than 30 seconds to put on and get up-and-running (check out the video demo in the Applications & Featured Projects section below).

The Ultracortex Mark III is the latest working version of the OpenBCI headset. You can find all of the 3D files. links to hardware, and an assembly on our Github repo. We designed it for maximum adjustability and ease of use. In our design thinking, we prioritized the use of dry electrodes (pictured in the images above). Using dry sensors significantly reduces the time needed for setup (no more sticky paste!) and makes the overall experience of wearing the headset much more pleasant.
