Regarding headsets before 2016, I can't say one way or the other yet. There's a good chance we will be shipping a small batch of early prototypes around to SUPER interested early adopters (it seems like you all fit into that category). This would be a really DIY version, requiring lots of hands-on assembling. Cost for this kit would probably be ~$400. Let me know if you're interested.
I would definitely be interested at that price point since Sculpteo is ~$750. Even more so if you're sourcing the nuts and bolts. I don't mind getting my hands dirty at all and was figuring I'd need to take the leads from the full kit and have to strip them etc.
Oh and I still have to solder the actual board together as well. I've not had a real chance to work with the kit yet beyond initial testing that everything worked. Very much looking forward to completing the project to start coding!
I bought dry electrodes from Florida Research Instruments. I measured the impedance with the Processing GUI and I found around 8 kOhm with the dry electrodes and 34kohms with the original wet electrodes coming with the openbci kit!
It's working great, and I don't have to wash my hairs after using the headset in order to remove the conductive paste!
I printed that with my Zortrax printer and quality is great.
Just one thing I would like to do is to modify slightly the electrode mount part A. My head is probably smaller that yours and I would like to put 4 spacers on the parietal lobe electrodes.
Could it be possible to share your raw 3D files? (STL can't be modified). I could make new parts from scratch in my 3D soft but I would rather like to modify your file.
Thanks and great job! I'm waiting to print the 3rd version soon.
Your UC #Mark2 looks great! Fantastic work! The print quality is really clean, and I like what you did with the zip ties. Also, thank you for doing the electrode comparison. We've found very good signal with the dry electrodes as well—to our pleasant surprise.
You may want to try printing some of the improved M2 spacers. They snap around the electrode holder without you having to take it out. This is very helpful, because then you don't need to unplug the electrode from your OBCI board to readjust the electrode's fixed displacement from the scalp.
Shoot me an email at conor {at} openbci {dot} com, and I'll connect you with our industrial engineer to get you the raw files. That being said, you should be able to import the STL into most 3D modeling programs, grab the vertices on the press-fit piece, and then move them upward, giving you room for more spacers.
Anfeng, Conor is referring to the FRI silver chloride comb sensors shown on the dry sensor thread. Not the trial combs that were printed from conductive plastic.
This is my Ultracortex Mark 2. It works perfectly. I used a USB Lilon/LiPoly charger - v1.2 and Lithium Ion Polymer Battery - 3.7v 500mAh. Those are very convenient.
Greetings all, I've been testing audio files created by Transparent Corporation for NeuroProgrammer 3 as well as some other online binaural audio files and such from sites like Brain.fm. Here's a 30 minute recording I uploaded to YouTube to demonstrate: https://www.youtube.com/watch?v=HA7qrdNzPqE
At any rate, just wanted to say the UltraCortex 3 has been great and I couldn't be happier with it.
I'm currently assembling my first Ultracortex v3 and I am wondering if anyone else is having the same issue that I am. It seems like my Octanuts are slightly too small and continue falling out when I try and screw everything else into the headpiece. The instructions didn't say anything about gluing in the Octanuts but I don't know how you don't have them constantly falling out without it.

Could you share some details with your dry electrode? I 3D-printed the electorde with openbci recommented material, but the signal is not good.
thanks,

I ordered dry electrode from www.FRI-FL.com yesterday.
Cheers,
You can find the "eyes-closed” and “alpha” waves in the EEG.
