William, thanks! ^ Oooohhh boy, I detect a rabbit hole of reading for me to fall into, @jmNZ!! I first got interested in EEG years ago, reading about Self, Addiction and Violent behavior. How do you read the Eulerian plotting? Given the…

Hi all - update to the above. In digging through forum posts, I see that the default gain on the Cyton is a likely culprit. The default gain is 24x. Using the SDK commands found here, I modified the gain on ch 1 & 2 down to 8x, which seems to…

Hi @jmNZ, I only know what I have struggled with in the past, otherwise I am just a grasshopper compared to many others in the world of EEG, EMG, and EKG. I myself use 1 signal channel electrode at Pz (an "earplug" wet/water electrode that I hac…

Hi @julienConscious, sorry in advance for the long post. I see that I was sloppy in the way I tried to explain the issue. I will try to clarify the current output, and hopefully you can suggest a next step to try. (I should have said "trace" in…

Once again, thanks William, I didn't quite realize it. @julienConscious - looking forward to your reply above. I am finding the signal loss confusing and frustrating. Hoping I just missed something and the solution is simple.
-
Hi @julienConscious - I have been using the thinkpulse electrodes and have some questions. Sometimes (I am not quite sure of the cause) an electrode will lose signal and go to zero on an oscilloscope type display. Lifting/reseating the electrode…

@wjcroft - perfect! Thank you. The pictures of the pin configuration with the ECG and EMG are helpful. I now see why I was initially confused as to the "save settings" feature. When it saves it does not prompt or automatically add the ".json" …

William, once again you have great ideas, thank you so much. The extension will be a boon. Just being able to more easily remove and recharge the existing battery will make things much easier. I will definitely think about longer lasting batterie…

Thanks @wjcroft ... if the short wires don't do the trick I will look at adafruits offerings. I prefer to give a good company like that some business.
-
Hi @julienConscious thank you for the info. I absolutely understand your recommendations. I will try to use the wires as-is and attach the unit to the headband. But if it proves uncomfortable, I will try adding 50 cm jumpers similar to this: am…

Thank you @wjcroft @julienConscious - hoping to find a solution to the above

ThinkPulse.... need extension cables Hello all, I just upgraded to a Cyton with the ThinkPulse starter kit. I will not be using all 8 channels at once, I will only be using 2 to 4 channels at a time. My current Ganglion rig has a velcro head…

More complexities with the Ganglion and pulse sensor than I first understood. I will have to read through the Emotibit Visualizer docs. The Emotibit website is a bit difficult to navigate, so reviewing the docs on github.
-
Thanks for clarifying that William. It looks like the Ganglion can accept the pulse sensor, so it was worth asking if it could support the Emotibit. Oh well. The software for Emotibit appears to be for recording and offline review. My use cas…

I think I figured it out. Looking through the OpenBCI_GUI code in github I see the following lines: "z" is the command. So, I tried: and it worked, I could capture the output in BrainBay: Awesome

Hi, I am a hobbyist. And I am new to OpenBCI myself but I have had this hobby for about 15 years. One of the real pros or academics on this forum may have a completely different viewpoint from my own. Interpret the following with this in mind. …

A little bit of gaffer tape works very well. Just want to protect the dongle from accidental moisture or rough handling. Now I know the adhesive on this tape is ok for electronics... never used it for that before.
-
Hi @bthomas999, I think it may have more to do with: * what electrodes you wish to use (active? simple cup electrodes?) * how many you expect to use at any one time, per your planned use case * how much money you wish to spend In my case…

@wjcroft said: Gaffer tape, used by stage and movie productions, is designed to stick well, but be easily removable. Might work as well for adding some padding inside your clear case to more snuggly fit the board. Looking at the prices on that pa…

Ahhhhh - the clear case, is definitely better. The switch is not being pinched at all and it is easier to reach, and the board inside of the case seems to stay relatively still with a gentle shake test. However, the case halves do not click secure…
-
Hi @wjcroft, see the image below. The switch is really buried in there and difficult to turn on/off. Its a little hard to see, but the board is not laying flat, and half of the case is leaning on the little plastic switch itself. In some position…

Hi @wjcroft, good to meet you. I see you often jump in with advice here! re: Adafruit Yes, you are right that hot glue is not removable... and in some cases would prevent heat from escaping. I'm not a fan of electrical tape, but shrink wrap mi…
