Hi William, Can I confirm the way to capture the EEG data from python? As I mentioned before, I am using the code at the top of cyton.py. When I saw the raw data of the first electrode, it contains the 50Hz noise, so I thought my program works a…

Hi William, I unloaded and loaded the kernel extension, then it was fixed. The latency was dramatically improved. But, the latency fluctuates between 1ms and 7ms ( and sometimes 50ms ) and is not stable. 7ms latency is not good for my purpose, …

Hi William, I applied a bandpass filter by myself, thank you. I have another problem. I used the sample code written at the top of cyton.py. Since the sampling rate is 250Hz, I expect the function 'handle_sample' is called every 4 ms. When …

Hi William, I purchased the Cyton Board and pro-assembled Ultracortex headset. I confirmed they work as expected using OpenBCI_GUI. Thank you for your help. Now I'm going to create my own program using python. But I have problem with them. …

Hi, The OpenBCI EEG Headband Kit is relatively inexpensive. I'm happy if I can use it instead of the Ultracortex headset. I want to measure EEG at Fz, but the product description doesn't include Fz. I also want to use dry electrodes. Is it u…
