Great! Thank you so much. I was specifically looking for something compact, and your board fits that requirement perfectly. The piEEG isn't as compact in comparison. Could you please confirm the following for me? * Is the schematic for piEEG…

Thank you. I never looked at it like that. Thanks again. Do you know any other ads1299 based tiny board like that which I can interface with development board and test it? Edit: I will try to get the evaluation board.

@wjcroft thank you the reply. I am aware of the warranty associated with it. My reason to ask this question came up when I was thinking to repurpose Daisy board with additional components to use it as a standalone EEG device. I belive someone has a…

Here is the sample app to get the stream of band power data from OpenBCI GUI via UDP connection to write to files. Also, we can't send FFT data. const dgram = require('dgram') const server = dgram.createSocket('udp4') const fs = requi…

Happy to contribute

@wjcroft thank you so much again. I figured that out already. I will share an app with the community soon.
-
okay. Done!

Yes, they were getting saved but in two different location. When I selected the custom location to save the recordings, only the Brainflow files were getting saved in custom location but the playback OpenBCI txt file was getting saved in the default…

@wjcroft @retiutut Just one minor update for you guys to look into the issue. Update : * Data is getting saved in both Brinflow CSV and Open BCI txt file for playback * I didn't see the playback in the folder because I was choosing custom l…

Thank you everyone. I was able to convert those CSV file into playback file with the help of python and some manual copy pasting. @wjcroft on the other note, I tried the older of openBCI GUI version but couldn't connect my board with it. Only 5.1.0…

@wjcroft @retiutut any help? I dont mind converting CSV data to playback file, if some can tell me how to do it.

Hey, I am using windows 11 22H2, OS Build 22621.1194, Windows Feature Experience Pack 1000.22638.1000.0

Yes, I have used the same GUI for all sessions. Although, there was an option to update the GUI but when I clicked it said, I have the latest version. To try other version, I will update you.
-
Hey @wjcroft, Yes you are absolutely right. The thing is it was recording the data before as expected. It was creating playback file as txt along with the CSV file but now it doesn't do that anymore. Previous sessions, prior to the last ones had a…

@wjcroft Thank you so much again for help.

@wjcroft Now that you have mentioned, I did look into the chip on the PCB. I basically got cheated. The chip on the board is ADS1299-4. I am freaking dumb. To check that further, I slapped the daisy board on top and voila, I get the same the behav…
-
@wjcroft Just one last question. can you please help me understand when or why do I get the message on channel which has no data streaming - "Data from the board doesn't change 0.00 uVrms"
-
Thank you @wjcroft I guess I made a mistake buying from aliexpress.
-
@wjcroft Sadly yes I left this hardware unused for few months and picked up again until I got the electrode and t20 paste. I ordered the electrode from OpenBCI us and it took sometime to reach here in India. I bought the Cyton board from Aliexpre…
-
@wjcroft I think my board is faulty. I can't see any data beyond 4th channel. As mentioned in the documentation even running finger on the pins would allow you to see some noise in the GUI. One thing, I also noticed that when I run the impedance …
-
Okay, Let me check and get back to you. But I have a question, can we use any kind of dry electrode?
-
Ops, sorry, I missed that one - A. **Electrodes Connection and Position - ** 1 electrode = SRB bottom pin : Near one ear 1 electrode = BIAS bottom pin : Near another ear 1 electrode = any pin between N1P - N8P bottom pin : Forehead ( I know I …
-
Hi Wjcroft, I did remove the daisy and run the board again this time again no change in the data. Now after reading the documentation, I also connected the Bias electrode injunction with the two electrodes that I was using previously, but no chang…
-
Hi wjcroft, Thank you again for the reply. I already found that muse micro-usb modification and that's there where the confusion arises whether I can use multiple electrodes or not. But thank you for the clarification.
-
Hi Wjcroft, Thank you for the reply. I was confused if there a is special way to do the connection because there are power pins and data pins but as you have mentioned, I can use any pin for my electrode, ref and gnd that clarified most of the thin…

Hey I am based in Canada, I would like to buy only Cyton board and WiFi Shied. Are you interested?
