• Hi, Since Wifi Shield is no longer sold on OpenBCI website, is there another way to send data from OpenBCI Cyton board to a computer/microcontroller at sampling rate higher than 250Hz? We are doing EMG-controlled project so we will need EMG data tr…

• I had the same issue with saving EEG data onto SD card of Cyton board. It really saves the data about every second recording (sometimes it doesn't save). Does anyone knows how to fix that? Thanks

• Thanks, William. I have checked the diode (D9) and 3.3V regulator (U5). The diode seems fine, but the output voltage of the regulator (DVDD) is 0V. However, after replacing the regulator twice, that problem still happens. It is very unlikely that al…

• I just want to find voltage difference between each electrode and the common ground one (SRB1 or SRB2?). Does including BIAS help reduce noise? So should I always use "Normal" as input type?

• Thanks, William. I have read that page, but I couldn't find when to use each input type. The example there use "Normal" only. When should I use the other ones such as BIAS_DRP and BIAS_DRN?

• Thanks for you suggestion, ratlabguy (or David?). My team is part of UBC. Yes, they are really gonna wear EEG caps under their helmets while playing hockey. My team knows that it is hard and no one has done that, but that is why we should try to mak…

• Thanks a lot, William. I'm doing EEG, and I need the sampling rate to be at least 500 Hz. So after I have he Wifi shield, how do I increase the sampling rate of SD card recordings? I have read the comments in the links you suggested, but the instruc…
