OpenBCI support for Bitalino Low-Cost Toolkit?

Peter_Gamma · July 2019

I m looking for an EEG solution for everyday use for
everybody. I found the Bitalino revolution board :

https://bitalino.com/en/

The
Bitalino Revolution board is low-cost and flexible. It can be used by
default with 3 EEG
electrodes:

All
inputs of the Bitalino Revolution board are multi-purpose.
Additional EEG sensors can be bought in the plux store:

The board
supports up to 18 electrodes:

Bitalinos
range of programming API allows to incorporate BITalino in custom
made software:

I
appreciate especially that Bitalino has Matlab support over
bluetooth:

But
still, the application support for EEG is limited.So here my question. Can the OpenBCI Software be modified to
support the Bitalino board?

Peter, hi.

Sorry, no, OpenBCI software and tools only support the data streams output by our hardware.

I suggest you check around to see if any Bitalino users have coded an interface to LSL, LabStreamingLayer. If the Bitalino can output LSL stream, then many EEG toolkits can read that.

Thank you William, very helpful

I m not a
programmer, and I don t have any ambition to become one. I m
interested in meditation and meditation research and found the
bitalino board has a great potential for it, but my search result was
also that EEG support for Bitalino is limited compared to other
solutions.

I recently bought
a Muse headband and the Muse Monitor and did some experiments with
it. I became interested in these colour bands with time-frequency
results:

I thought with more sensors than the
muse headband I would get colour bands which are easier to
interpret. I found in this video from Hofstädter
Krisztián using OpenBCI a
data quality which I would love to have:

Is it possible to
get with OpenBCI and a setup similar to Hofstädter
Krisztiáns such
time-frequency graphs?

I don t mean such a high quality of time-frequency graphs. But is it possible to get with OpenBCI

such
time-frequency graphs?

The actual names for these graphs are Spectrograms,

https://www.google.com/search?q=spectrogram

Many DSP Digital Processing System libraries, packages, allow production of such graphs, some even in real time. For example if you had the OpenBCI Ganglion board, you could connect it to apps such as BioEra or BrainBay or OpenViBE and get realtime spectrograms.

You can do the same with Bitalino, once you turn their sample stream into LSL. Does not require more than a page of code. BioEra and OpenViBE can read from LSL streams.

Thank you for your help wjcroft , this is encouraging. Bitalino can be used with LabStreamingLayer in Matlab:
