• Hi, I’m wondering if anyone could share their impedance values for the ThinkPulse dry active electrodes with the cyton and daisy 16 channel board on the ultracortex mark IV? I used to use the dry comb Ag/AgCl electrodes but the impedance on those…

• @lagidigu said: Hi there! I'm using dry electrodes with the ultracortex, and keeping the impedance to less than 5-7 kOhm per site. At what range of uVrms should I set the threshhold to consider the signal an artifact? Can regular brainwave…

• Hi, I'm having large impedances on my openBCI Cyton+Daisy board. These are dry comb electrodes, used with the Ultracortex Mark IV and openBCI Cyton+Daisy. The combs are brand new, I removed them and screwed them back on and these were the values I w…
