Braden, how are you??
Finally, for that project, I used the ganglion without the active electrodes. But my original idea was make a PCB witht two rows of pins. One row should be 3.3V and the other should be GND. In my opinion you must use the 3.3V power supply and the GND directly from the Gangloon Board, I think the active electrodes has low consumption.
Let me know if I can help you in some way.
Best,
Lucas.

Hello @julienConscious, how are you? Thank you so much for your time, I appreciate it. Your graphs look very nice. Luckily last friday my students made experiments, they controlled robotics vehicles using bci. For this, they use gel cap electrodes …

Hello guys, how are you? Thank you @julienConscious. I will answer you. Your experiment looks great and indeed you can see a very nice peak with the gel electrodes. I'm confident you can achieve similar results with the dry electrodes but it …

I use this comment to show you some pics (I accidentally clicked "Post Comment", sorry. All the experiments were performed using one Blue LEDs with a blinking frequency. The frequency was made using an Arduino with a square signal. I performed a …

Hello everyone, how are you? First of all, @julienConscious. @lucasbaldezzari is the signal you're looking at in the GUI the same signal that is processed ? I hope so! But sometimes I think for some reason the signals perhaps are d…

Hello everyone! How are you? Thank @wjcroft for mentioning me. Like you said, I have no SSVEPs using dry passive electrodes and neither active. I'm using Brainflow in order to make a BCI using SSVEPs. I have been trying to get SSVEPs using Gan…

Hello @wjcroft, how are you? Like always, thank you so much for your fast reply. I will try what you said. I remember working with an absorbent pad and your idea is great, I didn't realize. I will try to get some sponges like you shared in your p…

Hello guys, how are you? I tried to use the Ganglion Board with one Think Pulse Active Electrode and everything works fine. I only used one electrode because I have only one AVG and AVD connectors. So, I will print a pcb board in order to connect…

Hello Julien, how are you? Thanks for your reply. I will test them. I only need two PM connected to the ganglion. I will post information here. Regards, Lucas.

Ok, I will PM to Julien. I'm not sure what you are referring to, "...I don't know if the AVdd and AVss could supply the power for the Thinkpulse..." I don't think you would want to have the Cyton sending voltage over to your Ganglion / Thinkpu…

Hello @wjcroft, how are you? Thanks for your fast reply as usual. Explicitly states for Cyton + Ultracortex only. Additionally, the kit contains a power supply board, which only mates with the Cyton pins. Thus that power board is incompatible …

Thank you so much, William!!! Greetings from Uruguay.

Hello, how are you @wjcroft? I'm using the ThinkPulse active electrodes with the Cyton board, I can see very nice signals from channels of my interest in the OpenBCI GUI (reducing the gain less than 8x). But, when I recorded the EEG coming from the…

Generally 'flat' channels, channels with no signal, imply an issue with your connectors, wires, electrodes not making contact. You can use a digital voltmeter / ohmmeter, to continuity check the path from Cyton pin to electrode. While wiggling wires…

Hello William, how are you? Thank you for your fast reply. For the second graph I use the same conditions as the first one, same room conditions, same filter params (bandpass in 5Hz - 38Hz, Notch at 50Hz). On the other hand, some sometimes when che…

Yeah! The right word is "playback", thank you so much for this and the link, haha. I will let you know when I find the solution. Regards, Lucas.

Hi retiutut, how are you? Thank you so much for your fast reply. I will join to the slack channel, ¿do you have the link or something? About your examples, I know that the synthetic signals have 5Hz and 10Hz spikes, but I was wondering if you can…

Hi William! How are you? Great news and thank you so much for remember this topic! Best regards, Lucas.

Great! Thanks for your time, William! Best regards, Lucas.

Hello, William! Thank you so much. I will try using the LabStreamingLayer. One more question. Time ago I use BCPy2000 and BCI2000 in order to make a BCI using a speller by regions to evoke P300. I was wondering if I can use the OpenBCI Pytho…
