If you can attach a picture showing these electrodes i'll really appreciate it as well can i use paste on them? On 2 Jan 2015 14:44, "steeph-k" [email protected] wrote: >...

So what do think ppl? Just i have to use a paste on the ear clip and the forehead electrode?

Actually i've tried with paste and salt/water , always signal strength isn't lower than 26 and always meditation/attention is zeros even on the processing brain graph-er.

You mean the Tx / GND soldering? On 3 Jan 2015 10:49, "steeph-k" [email protected] wrote: > Shouldn't meditation and attention still go up sometimes even with a > connection value...
