As Joel mentioned, the Mark IV images you see from the Kickstarter campaign are purely conceptual. I've added them to our Github, in case you want to try printing them yourself, but they will change. substantially before production. https://gith…

Hey Corey, Thanks for the feedback. Are you suggesting that we implement 2 additional internal class variables (to the playground), that keep track of the x and y centers of the playground? Any other suggestions for the GUI code are much ap…

Thanks for the info, William. This is very helpful. Conor

A comment from John Pellman on the OpenBCI/Ultracortex Github Repo: " -- High Density EEG -- 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 …

Hi Gerald, I sincerely apologize for the delay. I'm not sure why nobody has responded to your emails. I'll look into that. Regarding your headset, we have 15 Ultracortex orders ready to ship (tomorrow), and your order is one of them. Thank yo…

Hi braveneuroworlds... This seems very odd. When did you receive your UCM3? Also, I just started a new thread specifically related to UC M3 feedback, design improvements, and suggestions: http://openbci.com/forum/index.php?p=/discussion/541/ultracor…

Lookin' good! Love the all white. Your screenshot shows a lot of high frequency noise—more than you should see (especially in channel 1). Is that what you're seeing typically? Conor

Great suggestions, William. I think both scenarios you've detailed are good solutions. The current Mark III kit comes with enough electrodes (21) to create an electrode unit for each site. This is a tad wasteful, however, since you can only target a…

It's available now: http://openbci.myshopify.com/collections/frontpage/products/ultracortex-mark-3-eeg-headset-kit-assembly-required?variant=7901127811 Also, we just announced a Kickstarter campaign for the Ultracortex Mark IV. Cheers, Conor

Howdy @Arale! 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 wel…

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…

Hey @Coreygo, so far I've printed everything out of our Rep2 printers. It has the precision necessary to get the job done, but I'm not sure if that is the case for all desktop printers. If you end up going with shapeways or another "printing as manu…

You could try to force it, but this design is not intended to work with them. It is designed to work with electrodes from FRI (listed above), which are cheap, dry, and they work well!
-
Fixed !
-
If your print volume is big enough, just print the front2 and back2. The other 4 files are in case you need to split the front and back in half, if your print volume is too small. You'll also have to print enough of the electrode mount components …

Hi Dave, It is normal to see a slight drop-off after the initial EMG spike, especially if you flex really quickly at first. That being said, it should not trail off completely while you are continuing to flex. For my EMG-powered projects I lik…

Hi everybody! It's official, the fix now works and has been verified for versions MAC OS X 10.9 (Mavericks) and MAC OS X 10.10 (Yosemite). Joel and I have now verified on 3 different machines, in addition to Marion's comp. Thanks a lot to @wjc…

Also, by latest April installer, you are referring to 2.3 from FTDI's VCP Drivers page, correct? That must be installed after installing 2.2.18?
-
Hmmm. I don't fully understand. Just gave it another shot start to finish. No luck. Is this ( $ sudo nvram boot-args="kext-dev-mode=1") all that's needed to do the kext-dev-mode nvram patch? And if so, when is the ideal time to do that? Immediatel…
-
Does it matter when we enable the kext-dev-mode patch? Also, just for clarification, can someone explain the difference between: sudo rm -rf /System/Library/Extensions/FTDIUSBSerialDriver.kext AND sudo kextunload /System/Library/Exte…

@wjcroft, I'm Yosemite 10.10.3 Now trying Marion's latest suggestions. Will keep you posted.
-
Hi all, I just tried @marion's approach but ran into the same issue as @Rceballos98: Upon: conor$ sudo kextload /System/Library/Extensions/FTDIUSBSerialDriver.kext/ I get the following error: /System/Library/Extensions/FTDIUSBSerialDriver…

Hi Fahad, Processing runs setup() one time at the start of the application, then: draw() happens repeatedly at the application frame rate systemUpdate() — called within draw() — handles updating all of the system data / variables systemDr…

Awesome. I'll be sure to keep the forum posted about V3 advancements, as well as 3D-printable electrode designs, and mounts for purchasable dry electrodes. We've been prototyping with these dry electrodes from Florida Research Instruments, and the…

Hi portela, Frederic FOIRY made this modification and pushed the files to a GitHub repo: https://github.com/memowaveB/MemoWave/tree/STL/OpenBCI/STL/Spiderclaw-V2-for-board-V3 I will say that this design takes a lot of tuning as a result of the…

Hi everyone, Please forgive the radio silence. I was traveling through Israel and London, evangelizing open-source BCI! I'm back in action now and ramping up again on Ultracortex R&D. We've been collaborating with Aaron (aka Threeform)…

Occasionally the radio will drop a packet. When this happens, it's typically just a single packet at a time. This shouldn't be happening more than once every 30 seconds to a minute though. One way to improve this is by making sure your batteries are…
-
My plan was to design it in Maya, because it's the program with which I'm most comfortable. Do you recommend something else? I'm up for suggestions. I have reservations with embarking on using another software, just because I've done so much with…
-
I'd also like to note: even though the V1 and V2 Spiderclaw designs are deprecated for the V3 OpenBCI board footprint, I encourage anyone/everyone looking to jump on on the convo for V3 to print & assemble them. That way you can experience the b…

Hi everybody, Sorry for the delay in joining this thread. I just re-posted the documentation for the V1 and V2 Spiderclaw designs. This was initially posted last May, but somehow got misplaced when we renovated our site. It's back in action and I …
