Cannot seem to find comfort insert in the collection of STL files for the M4.
I noticed the STLs come in 3 different sizes (small, medium, and large). What head sizes are they meant for?
In the README.md is written "Take your QUADSTAR and stretch it so that it fits over the OCTARING" but we couldn't do it.
We tried by printing QUADSTAR bigger of 4% and of 5% but with this enlargment the OCTARING won't fit.
Can anyone explain how they managed to do this tricky part? Thank you
The Mark 4 Model is already existing, judging from the pictures on http://shop.openbci.com/products/ultracortex-mark-iv
Why isn't it released yet?
I showed this to our printer guy and he suggested:
Whoa! Too large, too much support required, I would think that with our printer there would be a 0% chance of success.
I'm wondering if there is a way to make this project more friendly a wider variety of 3D printers.
Perhaps break the frame into smaller components would help?
Even when cutting off the no-touch connectors at their base, which gives the maximum length of the Gold Cup Electrodes wires, the length of the wire is simply not long enough to reach the forehead electrodes.
I have a wire with the right connectors to make an extension for my build, but if someone tried to build this and didn't have that, it would be annoying.
Has someone actually used these wires in constructing a headset? Have a photo? Maybe the Gold Cup Electrodes wires are shorter now than when they were specified? This is with a medium sized headset, so the problem would probably be worse for a large.
Current instructions indicate that the model must be scaled before printing. I have tried printing per the instructions however the hardware does not fit.
Please update repo with properly scaled stl files that don't require any modification and are ready to print. Please also add instructions with pictures detailing the assembly process for the mark IV.
Conor, Joel and team, great tutorial and design evolutions!
Minor typo, isn't the SRB pin closest to the board SRB2 and not SRB1 as stated in the README? It is clear from the photos that the pins closest to the board are used. But some other documentation, for example various places on the forum, shows reference on SRB2.
Cheers, William
With a reasonable cost. 3D systems quoted ~4K.
Thanks!
Can you post the stl for the medium and larger versions of the MARK IV?
This doesn't look anywhere near like the electrodes that came with the OpenBCI V3 and there is no part list telling users to get any other ones.
Something doesn't match up here.
Hey,
I would like to know if there is a tutorial to make the electrodes we can see on the Ultracortex IV's pictures ?
Thanks!
It would be great if the files were designed to be printed in to so not PRO 3d printing machines.
As well the orientation print way too much support.
Please help!
Just wanted to drop a note here that recently the FreeCAD[1] community[2] has been helping to optimize another open source medical device, otoscope[3] (created by GliaX). They didn't have any CAD files available on their repository[4]. Anyway, the idea is if that if this project needs any help or has questions please feel free to open a thread on the FreeCAD Open Discussion subforum[5].
Cheers and thanks for all your open source efforts!

In the instructions about including the rechargeable battery, how is the charger included and connected?
"Embed OpenBCI into the Ultracortex
Connect your ~500 mAh lithium ion rechargeable batter to the back of your 32bit OpenBCI Board. Then fold the battery and its wires neatly behind the board before inserting the board into the BOARD_MOUNT. You can then use one of your #4 Drive Screws to secure the OpenBCI Board to the BOARD_MOUNT. Typically you don't need to use any #4 Drive Screws because the BOARD_COVER locks the OpenBCI Board in place, but in this case it's a good idea because you'll want to see where you're connecting your wires."
Hi all,
I encountered an issue on opening stl download link for board holder and cover of 'Nova' headset.
Can anyone post it again ?
Thank you very much.

Using the parts listed for https://github.com/OpenBCI/Ultracortex/tree/master/Mark_III_Nova_REVISED, I observed the following.
There seems to be some sort of reaction or corrosion when putting together the electrodes and the machine screws.
The photos (attached below) show an electrode as it comes out of the plastic shipping bag beside electrodes that have been assembled into their pods.
The assembled pieces were put together 24 hours ago. One can observe what appears to be corrosion between the head of the screw and the electrode.
They were not exposed to water. They were not screwed together very tightly. Electrical conductivity has not yet been affected, but if it continues, enough corrosion could prevent signals from conducting through the wire or being picked up at all.
These are parts ordered directly off the links in the list on github. There were no substitutions. I did not use different parts.
So... what's going on here? I shouldn't be seeing any corrosion between these parts, right?
This is being built for a hackfest that will be held next week (10-11 September 2016)
https://sites.google.com/site/ieeebcihackathon/
Here are some suggestions for things that could be improved or made clearer in the assembly guide. Some points are sort of nit-picky, but I'll include them just in case!
Do you already have a model created for the MIV Chip Holder? How are you mounting them to the frame? Zip Ties?
Hi all,
Thanks for updating the Mark III_Nova STL file. The current back and front frames are larger than my Printer printable size which is (7''x7''x7''). Is there any way which you can further break up the head frame (i.e., to 4 pieces)?
On the other hands, what should I do with my printer?
Hi,
We're using openBCI for a senior thesis project to make audiovisual feedback from eeg, ekg, and mmg. We're lovin openBCI, but we're starting to think about headset design. We want to make a few edits to the ultracortex, but the .stl files are not editable in solidworks. Can you post the original CAD files (.prt)?
Much appreciation,
Mohit
This might be more of a suggestion for a future project than an improvement on the present iteration of Ultracortex, but I thought I'd throw it out there anyways.
A small, but growing, number of researchers are scanning with 32, 64, 128 and 256 electrode systems in order to employ a technique called source localization. Source localization, as its name implies, allows you to pinpoint where EEG signals are coming from in a way that gives spatial resolution reminiscent of fMRI (though not comparable; fMRI voxel sizes can be as low as 1 mm isotropic, while EEG voxel sizes tend to be around 5 mm isotropic). This technique, though not without controversy (what scientific methodology isn't?) is something I would be interested in seeing become more prevalent, as it seems to me that it would be much more cost effective to gather large datasets with EEG than with fMRI.
There are some high density nets on the market today, and while they're cheaper than fMRI, they can still be rather pricey (upwards of a thousand dollars per net). In a time of dwindling scientific budgets, these costs can be prohibitive to some labs that otherwise might have wanted to try using this technique. In light of this, I think that it would be neat if there were an open source alternative that labs could try out (even if it weren't necessarily as fully-featured as the nets that are out right now).
Here are a couple links for you to check out concerning source localization if your interested:

Can you post the final mark IV stl with assembly instructions the current ones are not correct.
Hello,
I am working on printing the Ultracortex right now but, would like to make some changes to the electrode holder. I read a previous ticket that you guys were looking into providing IGS files for some of the parts. If this is not the case, would it be in realm of possibility to get a drawing or dimension sheet of some of the parts.
Thank you very much,
Sam
