hi everybody

i bought openbci with daisy 

i want to start testing my program on it 

so i follow the instruction in the guide in this url

http://docs.openbci.com/Hardware/05-Cyton_Board_Programming_Tutorial

 but when i reach this step "

Plug in Dongle and Select Serial Port"

there is no port activated on the list, why is that?

Good morning,
My cyton board and usb don't work.

I did some tests with Open Gui. It doesn't detect the openbci cyton. There's a heating side on the openbci board and a strange smell. .

I did several tests before it worked very well and then today nothing. I do have the latest version of the driver.
I have a windows 10.

The key flashes blue, indicates the output but does not connect to the openbci board (no red light).

What can you do? Thank you.

Hey. Where can I get the scheme with layers? What I have here is https://github.com/OpenBCI/OpenBCI_Wifi_Shield through KiCad and I get it, and I can’t understand where the second side of the board is.

<wish we could tag multiple categories>

Hi All,

Before I start on the journey, just wondering if anyone else has created a version of OpenBCI_Python for the Ganglion that runs on Windows.  The bluetooth library, bluepy, seems to be only supported under linux.

I was thinking of investigating using pygatt or pybluez as an alternative.  Maybe I'll get lucky and find that someone has ported bluepy to windows!

My final goal is to stream over LSL to software such as OpenVibe and Matlab (I have been successful with the Cyton and I've been using LSL with other EEG hardware for many years).  Other options such as the OpenBCI_GUI (freezes when streaming to LSL) and the OpenBCI_LSL (no Ganglion support as far as I can tell) might be options, but both have issues as well.

cheers,

Trent

Repo in question: https://github.com/OpenBCI/OpenBCI_NodeJS_Ganglion

Hey folks,

I'm running a research topic and we decided to work with the Ganglion board.
I've been trying to look for any method that will let me stream or send data and one of our hopeful options was using OpenBCI NodeJS Ganglion
I've been able to successfully run all prerequisites in order to run it, however I'm stumped by why it keeps asking me "a float is required."
(Ignore file directories, I've been trying to experiment with some of the node package incompatibilities in order to see if that was the problem)



I've also replicated the problem on a Linux partition to see if it was problems with BLE packages, only to get the same "a float is required" error.

If anyone has suggestions, or has ran into something similar recently, I'd appreciate if you could lead me to the right direction.
Cheers!

I recently lost my arm and decided to begin making myself a new one. I have little experience in robotics or software development and studied biology during my undergrad but figured it might be easier to make a robotic arm than try and grow one back Ha! If anybody is interested in collaborating with me in this relatively lax and long term project I welcome the help! Today marks Day 1 02/03/19 I'll check back in periodically to gauge progress! Thank!

Hi,

I just noticed that when I try to turn impedance measuring on my Cyton + Daisy that I get "Error Code 430 invalid channel number". I have two boards and the error is the same for both of them. I don't know whether this is a problem of the OpenBCI_Gui or Hardware problem.

Do you have the same error?

Best,

Aleks

Hi there! I am in dire need of spikey electrodes that can be connected into the snap-in wires.

It would greatly alleviate some design issues I am having as well as make it so much more easier to change the oxidized electrodes, lowering the difficulty level of maintaining the system for the final customer.

Do they exist?

How/where do I get some?

If they do not, can they be ordered to be manufactured or something?

Thank you.

Hi ,

I need to complete P300test. I have Ultracortex mark IV headset and by OPenBCI Gui, I could run cyton board successfully. But when I want to interface with OpenVIbe v 2.2, it didn't connect. Like: It not showing the COM3 port on Openvibe. It means, it can't detect Dongle port. Can you give me some outline ? Operating system is W10.

Hello,

i saw in the openbci webpage that the Ganglion have a sample data rate of 200Hz. However, I have some questions about that:

1 - Are there some way to increase the sample data rate? I saw in the forum and website somethings about that, and one way is replace the rfd_77101 ic for a wifi chield , so, which wifi chield i should use for this? i need to increase this sample data rate because i'm working with machine learning to control a smart prosthesis and i'd like to obtain 1kHz in the sample data rate.

2 - Can i connect the MCP3912 in a microcontroller like an arduino without the sd card reader and the rfd_77101? I'd like to connect this directly to a microcontroller.

I wanted to ask why isn't there any documentation for the "DIGITAL OUPUT ON OPENBCI CYTON" , there's one already for the "8BIT BOARD"
Can i just use it as a reference to program the Kit's ATMega328P or it's considered as outdated ??

Hi,

I am planning to develop a mobile app in both iOS and Android which will monitor the data from Cyton board. I have seen that there are SDKs available for Java, Nodejs etc. Is this possible to connect the board from iOS and Android mobile app and get the data? If so, can you share some examples?

Hi! I am new using python, and I am having troubles for making it works. Sorry if this topic is already posted, i didnt see anything while looking.

So well, I am trying to get EMG signals using the GitHub of OpenBCI avaible for python. But I am having some errors. I already install all the requirements, and I am avaible to use the script test.py. So I can get the signals from my cyton, and printed in the console (I am using the interface Sublime Text3). However, this printed command enter in a infinite loop, so I want to know how can I stop it.

In addition, when I use the script User.py, it appers to work, but when I try to use the pluggins commands, it didnt work and appear to have an error asociated to a SD card. I must have this card in order to get signals, print or stream? Below are the copy/paste of all the proccess until the error message appear (The pluggins appear in the list so I feel it not an error asociated with it).

I am using the Cyton board of 8 channels, the OpenBCI_Python GitHub, and running in a Windows 10 System with Sublime Text 3.

I have found these so far online, all a bit small:

Hello everyone!

Looking the descriptioin about the dry electrode from FRI, I read the words disposable/reusable, so I'm afraid about the life span

of the electrode, the coating get off as you use the electrode?

Another doubt is about the material, I could not find about the material of this electrode, it's really covered of Ag/AgCl?

Thank you so much for the help.

I want to verify what data gets written to file in the OpenBCI GUI. The live display suggest implies a windowed RMS value - is that what gets written to the file? In the top left (if time series is selected among hardware settings options) there is the option of a band pass and notch filter... if these are active is the saved data processed? If these are not selected the live display still suggests a windowed RMS value... so I'm a bit confused. thanks.

I'm recording sEMG at 1000Hz using Cyton and wifi shield.
