Start of Summer Update!

Posted by Joel Murphy & Conor Russomanno (Creator)

Hello backers!

Forgive the delay since our last message. We’ve been hard at work in the R&D phase for the new OpenBCI products, and things are coming along nicely. We have plenty of news to update you on—some good, some bad.

The good news:

The Ganglion and Ultracortex Mark IV are progressing nicely. See below for more details on these products.

The bad news:

After many conversations with experts in the field of neuroscience and brain-computer interfacing, we have made the difficult decision to discontinue development of the tDCS Shield. From the beginning, we stated that safety is our #1 priority. At this point in time, we do not have the resources to pursue a tDCS solution that we believe is both cost-effective and safe. If you placed an order for a tDCS Shield through our online store, we will reimburse you in full. Refunds will be completed by the end of this week (6/24). Please reach out to with the subject “tDCS Refund” if you have any other questions, comments, or concerns. We know that many of you were waiting anxiously for the release of this product, and we sincerely apologize that we will not be able to deliver on it.

It is with immense sadness that we inform you Gal Sont passed away last month. Gal battled ALS for 6 long years. He was an inspiration to so many. Gal was a father, a husband, and a role model to all who knew him. Though it was our plan to work directly with Gal to create a custom-fit Ultracortex and we will no longer be able to proceed in this direction, we still have every intention of working directly with an individual in need to create a custom-fit, head-based biosensing controller. We will keep you informed as this project progresses. In the meantime, keep Gal and his family in your thoughts.

As a result of transitioning some of the Ultracortex Mark IV design to injection molded parts, the delivery date will be delayed by approximately 2 months. More details below.

The Ganglion Board 

Updated Delivery Date: August 2016

We just received the latest Ganglion prototypes and we are now populating and testing them. Additionally, we are collaborating with Push The World LLC to write the new Ganglion firmware. As of right now, everything is on track for an August delivery of the Ganglion Boards. Here’s photo of the latest prototype in the early stages of testing!

The Ultracortex Mark IV 

Updated Delivery Date: October 2016 (delayed ~2 months)

Based on the feedback we received from the survey we ran in April, we have now settled on the final node network for the Ultracortex Mark IV frame. Thank you to everyone who replied to the survey. The new frame design is based on the 10-20 network diagramed below left. The lower right render depicts a photo/photoshop concept of the latest frame design. The frame provides access to 35 different 10-20 System locations.

For the mechanical parts (electrode holders) of the Mark IV, we have decided to move forward with an injection molded solution. This is great news with regards to ease of assembly and part quality. All electrode units will come pre-assembled regardless of whether you are receiving the Print-It-Yourself, Unassembled, or Pro-Assembled headset. See the reference image below.

As a result of moving in the direction of injection molding, we are forced to extend the delivery date by roughly 2 months. The trade off for switching to an injection molded manufacturing process is a longer manufacturing timeline. That said, we are really excited about the new part designs. We expect the parts to be very high quality and much easier to work with than the 3D-printed mechanical parts of the Ultracortex Mark III.

Interns In The House

We are very excited to announce that we brought on five very talented interns this Summer: Colin, Niyathi, Gabe, Irene, and Wangshu. They are working to improve the OpenBCI documentation, while implementing the 32bit Board, Ultracortex, and Ganglion for personal projects. Stay tuned for what they come up with!

OpenBCI GUI V2 (under development)

We are currently working on the next version of the OpenBCI GUI which can be used as a standalone app or developed further with Processing.

Expected GUI additions and improvements will include: 

  • Ganglion compatibility 
  • EDF data format export setting 
  • Accelerometer visualizer 
  • 4/8/16-channel interactive EMG visualizer 
  • User methods for accessing raw and filtered uV and FFT data 
  • Upgraded interactive 10-20 head plot w/ presets for Ultracortex Mark III and Mark IV 
  • Various bug fixes, as detailed here: 
  • Various data output/input protocols: OSC, LSL, UDP, etc. 
  • Interactive GUI tutorial embedded in app

If you have feedback/suggestions please add them as issues to our latest Github repo, or email us at

Past & Future Events

Over the course of the Spring, OpenBCI was present at a number of great BCI/Neurotech events. At Xtech & Neurogaming Expo in San Francisco, Conor gave a presentation on Brain-Computer Interfaces and led a series of workshops on OpenBCI.

We were proud sponsors of the 6th International BCI Meeting in Monterey, CA. We were joined at the event by our friends from NeurotechX. At the event, Jeremy Frey presented a paper comparing OpenBCI with g.tec hardware, and OpenBCI did quite well!

In early June, Conor gave a presentation titled “The Democratization of Neurotechnology” at NeuroTech NYC. Other presenters included Ana Maiques from Neuroelectrics, Rosalind Picard of the Affective Computing group at MIT Media Lab, and Arshya Vahabzadeh of Harvard Medical School and Brain Power

If you’re in NYC, Joel will be giving a presentation on OpenBCI at the 13th Annual Games For Change Festival this Thursday (6/23). Go check it out!



Prices Going Up!

Congratulations, Kickstarter backers and pre-order customers! You received a substantial discount on the Ganglion and Ultracortex Mark IV. As a result of some unexpected manufacturing and assembly costs, the retail price of the Ganglion and Ultracortex Mark IV will be going up by 125-150% on July 1st.

If you have been on the fence about pre-ordering any of the new OpenBCI products, now is your last chance to get a serious discount on the technology before the pre-order prices are increased!

      I think it was a good decision to cancel the tDCS shields. I was concerned about how you were going to make electrical stimulation of the brain safe without the presence of an expert. I do think non-invasively measure bioelectric potentials is something anyone could do. Can't wait to receive my Ganglion.

      RIP Gal

      Disappointing regarding the tDCS shield, but understandable from the point of a manufacturer. However, can you please go into details surrounding this decision (ie what was identified as being dangerous etc)? I've seen several projects for DCS and it's an area I'm following of interest. I also have a friend (who's a neuroscientist) that is always talking about DCS and so it would be nice to share/discuss this information with him.

      Sad news to hear about Gal. RIP
