OpenBCI Arduino Shield - Batch Interest?
Hi.
I've had an interest in personal EEG for a while now.
I made up a protoboard version of the OpenEEG Analogue component once a few years ago but never followed through at that time with a bridge to a logging system or gui.
These days the options for interfacing the analogue circuitry are plentiful...
I think the Arduino shield form factor is a great idea.
I appreciate and understand the reasons why OpenBCI has moved away from the Arduino form factor for their Kickstarter.
I have backed the kickstarter and look forward to April 2014 to get my hands on the product.
That said... I've never had a single kickstarter deliver on time... even the best ones...
(I am currently *still* waiting for one promised for *last* Christmas... not the one just gone...)
It seems people dont estimate the production timelines very well, which is understandable.
Maybe the OpenBCI kickstarter will be different... I certainly hope so...
(and I'll be more than happy to eat these words if they do deliver against the timeline)
So... having the time right now and a bit of enthusiasm... I'm interested in making up some of the Arduino form factor versions myself...
The schematics are available but the board files have not (as far as I can see) been shared.
I *suspect* that is because of those inherent issues of using a platform that may be mis-wired to mains and... well... kill or maim someone...
I'm quite happy to take these risks for my self... and am considering a third party board producer to make up some boards and assemble them myself...
I'm also interested in using the Olimex active electrodes - in a modified format - with the OpenBCI Board.
I have a few questions related to this...
- Is it possible to get the board layouts uploaded as well as the schematics?
I can make these up myself if not, using the images as a guide to laying them out in a similar fashion.
- Are there any know issues with coupling the olimex active electrodes with the OpenBCI boards?
- There are two revisions shown on the website currently... 2.1 and 2.2... differing in the DC isolation methodology... I imagine 2.2 came after... and was probably in response to 2.1...
So... did the 2.2 work out better for any reason? It looks more practical for assembly and a bit tidier...
- Is anyone else interested in going in on a batch of boards?
- Am I exposing my self to liability in being a middleman in this way?
- Can I avoid all this by buying an OpenBCI Arduino shield from someone else who has made up more than they need?
Cheers.

Our schematic files are available, and you could certainly use them, along with the photos of our work, to produce your own board. Before you do, I suggest you look into the standards for electrical isolation. Here's a good place to start learning about it.

OpenBCI disavows and disclaims all liability for the results of your work, or of anybody else's work who may be lurking here.
come back when you have more questions. separating the GnD planes is fun and tricky!

I am currently going to do the same as you!
What progress did you make so far?
