New user, Introduction plus 20-something Questions (Ganglion)

LidiaLidia Netherlands
Hi all,

Let me introduce real quick: Lidia, from the Netherlands,
almost 40 years and interested in all things. My dad made ECG
biofeedback device in the 80's with his collegue at Philips, and always
told interesting stories about it. Sitting at the couch twee weeks ago,
talking about meditation and how to measure that, we came back to
biofeedback. Fast forward a few hours of surfing google and I had bought
the ganglion, plus goldcups, paste and a BLE dongle. It arrived
yesterday, and all works as expected.

of course, the openBCI
software is nice and all, and the focus widget is nice. But the real fun
lies in making your own widgets. My question is how to get the data
that the openBCI GUI uses to visualise stuff.

now, back off a
moment. I have some programming skills (hanging on by my fingernails and
some education 20 years ago in turbo and Matlab). Husband is good with
PHP and all kinds of languages and willing to help. I see guides (or
musings) about LSL and matlab and couplings with Brainbay and the like.
Have not enough skills to do that, or not yet anyway.

What I
want, is to make a widget, similar to the focus widget integrated in the
GUI. I don't want to use the 19bit system thing and do all FFT
calculations myself, as the software already does that. I want to use
the values that is used by the openBCI GUI, and work with THAT, real
time. Must be possible, since the GUI also uses that data to display
graphs and the focus widget.

Actual question: can you adapt the
GUI to make your own widgets? I can use the focus widget to use the UP
or SPACE key, and could use that as input for a mini game of my own. But
I want to alter the uV limits, cutoffs and other things Jason did in
that widget. Some basic python is available, and willing to learn more.
But first need to know if I can access the data that is there in the GUI
real time.

God, I hope I am being clear. Definitely not a programmer, so please be patient :)

    Lidia, hi.

    Did you find our Docs section?



    All the Widget source files begin with 'W'.

    Processing tutorial,

    That looks like exactly what I need. This makes for a few nights of fun, thanks for the help. Had not seen it yet!

    Honestly, BrainBay is going to be easier for quick prototyping. No programming needed.

    But BrainBay wants me to select a ComPort, and I use the BLE dongle. I tried, couldn't find comport, and read up here in the forum that the Ganglion with BLE is not supported. Am I wrong? is that fixed yet? Because BrainBay would indeed be easier.

    Hi William,

    Sorry, but I cannot get this to work. Perhaps because this:

    For Ganglion the BrainBay integration needs the GanglionHub bridge for interfacing with the Ganglion. To achieve this, the path to GanglionHub.exe must be specified in the Brainbay application settings. The recommended way is to install the OpenBCI GUI for first operation of the Ganglion, and then providing the path to Ganglionhub.exe (which is located in the /data subfolder of the OpenBCI GUI).

    In the /data subfolder of OpenBCI GUI there is no Ganglionhub.exe

    I installed the Hub (as I also need that to run the OpenBCI_GUI.exe, and that runs fine). Missing something?

    Oh, seem to be able to connect to BrainBay, as the impendance checkers are working and the blue led stops flickering.
    When loading up a demo like alpha training for instance, the connection is immediately lost, and cannot be established again through insert element > source > biosignal > OpenBCI Ganglion. The popup does not come up where I can connect the ganglion to BrainBay

    Right. Sorry. I will stop yapping and start playing. Figuring stuff out. No need to reply :)
