Salesman said there were two sizes. Ten20 gel is appropriate to use in that case? Or I should buy another one?

Hi, I want to buy g.GAMMA cap and use that 3D printed electrode holders. That cap is in twp version: with 2mm and 5mm holes. Which one was used in this case?

I'm always checking FFT in OpenBCI_GUI. When I recorded: https://drive.google.com/file/d/0BwCCA0mNmuFJbV9RVDhjVEZ2Y0E/view?usp=sharing then I obviously saw a response in OpenBCI_GUI "FFT window", but never again. When I see a response in Open…

https://drive.google.com/file/d/0BwCCA0mNmuFJa0c4MXJYaW9PYmc/view?usp=sharing Today I tried the next attempt. And again still nothing. It should be possible to see 4 stimuli: 10 seconds for 10,20,30 and 40 Hz. I think that I have tried everything.…

No, this is spectrogram from a single electrode. I decided to show one spectrogram because all (from all 6 electrodes) look similar. I think that I have a problem because my measurements are not repetitive.

This is my yesterday's result (one electrode connected): https://drive.google.com/file/d/0BwCCA0mNmuFJbV9RVDhjVEZ2Y0E/view?usp=sharingI thinik this is a great result. But today I've tried with 6 electrodes: https://drive.google.com/file/d/0BwCCA…

I've connected three electrodes approximately in my occipital area and then I've checked my alpha waves. This is the spectrogram from the electrode with the strongest response: https://drive.google.com/file/d/0BwCCA0mNmuFJNGltTm9lVzd2dEU/view?usp=s…

I have prepared a photostimulator: https://drive.google.com/file/d/0BwCCA0mNmuFJXy00Y0RPdTdFcU0/view?usp=sharing I have connected bias electrode to my left earlobe, srb2 to my right earlobe and 3 electrodes approximately in occipital area. I…

So we are not going to know the approximate date of the premiere?

Which electrodes from 10-20 standard V3 can be mounted on Spiderclaw? I am especially interested in electrodes O1 and O2.

Has anyone had any experience in SSVEP stimulators projects? Do you think the Aruduino is a good device to produce SSVEP stimuli in 10-50 Hz range? I tried to do that but I think that I can't produce steady state frequency. What is an acceptable osc…

I have done it successfully. Maybe the code doesn't look elegant, but i think this is the simplest way. I didn't want to change a lot of the code. OpenBCI_8bit_SD.ino: int triggerPin = A0; byte triggerValue; void setup(){ ... pinMode(tr…

Tutorial for 8bit Board will be very helpful. I tried: LIS3DH AccP; ... int triggerPin = A0; int triggerValue; int lastTriggerValue; void setup(void) { ... pinMode(triggerPin, INPUT); triggerValue = lastTrigg…

On my Github I uploaded a working ver of my app. I hope it will be useful for someone. All sugestion and comments are welcomed.

I have question about that tutorial ("EXTERNAL TRIGGERING THE HARDER WAY" part). Where can I find "18 pin"? I understand that this tutorial was written for old version of OpenBCI. Am I wrong?
-
Now, all is working fine. Thanks for all of your help, tips and hints! https://drive.google.com/file/d/0BwCCA0mNmuFJZDJVbnVDTVkzQUk/view?usp=sharing (signal correctly recorded from my wirst)

I analyzed the incoming data. Indeed, the problem is with the buffer. My app is losing incoming samples.
-
I implemented "interpretBinaryStream" from "OpenBCI_ADS1299.pde" in my app... and I still have the same problem. I don't know where I made a mistake.

This is result of my small research:https://drive.google.com/file/d/0BwCCA0mNmuFJRkVNNzRpdmxUc1k/view?usp=sharing (top: before filtering, bottom: after filtering) I think that filters are implemented correctly. I used: http://openbci.com/inde…

Hi, I have next problems. I'm trying to implement filters to my app. I've been fighting with that for a few days. I rewrote filters code from EEG_processing.pde, but unfortunately I received weird output (below). So my next step was to check output…
-
The orginal image I posted is no longer relevant. I think that I have correct conversion. I'm trying to rewirte filters from OpenBCI Processing software (filterIIR function etc.). Maybe you suggest to do it in another way?

I don't know how to edit my last post, so this is my plot: https://drive.google.com/file/d/0BwCCA0mNmuFJQzNWTHdXRjdwX1U/view?usp=sharing So, it wasn't a problem with the batteries, but I forgot to implement a function to convert 24bit samples in…
