Hi there,I won't be able to complete my sleep monitoring device, not being allowed to access the MASS sleep database (only for institutional scientific projects, requiring to be accredited by an ethics review board). I haven't anticipated that the a…

Hello Billh,Yes, the classification in red is the one of the CNN-RNN. It is its first training, in a 5-fold cross validation, on 39 individuals of all ages drawn from the physionet database, which is not so much, and with an electrode set-up differe…

Hello s_arty,My fist step is near completion: - The OpenBCI_GUI streams directly to OpenViBE & all OBCI packages are now running smoothly (still a remaining problem with the content of the LSL stream outputed by the NodeJS/noble package though,…

Hello there Bluepy / btle & OpenBCI_Python runs smootly within a full fledged linux OS (Mint). Back on the windows 10 OS, OpenBCI_NodeJS_Ganglion easily finds & connects to the Ganglion to output a lsl stream (merci beaucoup NodeJ…

Hello William, not sure it's an OpenBCI or even a bluepy / btle issue: this hardware access problem appears to be linked to the Ubuntu linux I use, WSL (Windows Subsystem for Linux), nice for certains things but giving me an impoverished access to h…

This seems a problem only related to the bluepy / btle part since:$ sudo python ./btle.py e5:98:a9:ea:3d:fa random ...results in the same error (both with random or public): Connecting to: e5:98:a9:ea:3d:fa, address type: random Running /hom…

Hi s_arty,I think one of the Neuroon Open backers on Facebook (Tibor Pajer) has designed an interesting board for that purpose (lucid dreaming). The main challenge of my step 1 is to implement an offline, reliable sleep scoring algorithm. Ideally, …

Hi s_arty, I just received a Ganglion board and I am assembling a headband for sleep monitoring, my first step will be to transmit EEG/acc data via BLE to a laptop for post night processing, to benchmark sleep scoring algorithms. my second step w…

I definitely need to convey the signal outputed from the digital pin of the Ganglion with a wire, a bit like http://docs.openbci.com/Tutorials/08-Audio_Ouput_8bit_Example ...maybe there are ways (beyond than increasing distance between wires) to…
-
This is a powerful reason indeed. I could try to see if/how EEG channels are perturbated by signals on the digital or analog output pins.Would you know if this has already been tested ? (just changing a digital pin state during the EEG acquisition).…

Is it because the Ganglion firmware does not leave the possibility to receive such stimulis and It would require to introduce a new (timed) type of command in this Ganglion firmware ? (to generate a high pulse at a given time for a given duration on…

Ok for the OBCI -> OV via the LSL stream (if it does not create delays), but reversely, OV can send (processed/unprocessed data &) stimulations out from Designer (using the LSL Export box): while it is streaming the data from the board, can…

Hi WilliamI will stick to acoustic stimulations, but I would like their waveform (phase, freq., amplitude) to be adapted in real time and not be a fixed train of stimulations. My immediate concern is to see how I can implement on board in real time…

Yes, I know these products, the SleepSmart will only be available in 2019 in Europe/France (~350 € in the US) and Dreem is a very nice device (~500€), but it is not easy to get access to raw data for the time being. I am also a KS backer of the Neur…

Hi William,Yes, bandpass-filtering and estimating the delta power... ultimately, it is to try to implement a sound stimulation that would be in phase (phase locked) with (a part of) the delta EEG waveform, and I was wondering if a biquad (IIR) filte…

William and Joel,Thank you for the useful information ! So we can read analog values and stream them in the Auxilliary data ( ganglion.useAux = true; ganglion.auxData[0] = analogRead(Ax); x=3;4;5 or 6) and modify the sample rate. And it is simi…
