The Olimex electrodes,

I moved your question over to this existing thread on the Olimex actives. See previous posts.

@biomurph How did you set up your electrodes for measurement? I would guess the recording (Px or Nx) and reference (SRB) electrodes need to be active. However the Bias (or ground) electrode should be

Joel @biomurph has made a couple posts regarding his use of the Olimex actives.

Hi, I have been trying to use olimex electrodes with cyton board to display real live data. 

I believe Joel @biomurph or someone in the lab did experiment with the Olimex AE's with OpenBCI; and got that to work. But needs 5v. And form factor is a bit clunky.

We have used the Olimex active electrodes with good success here.The connection should be

I am working with a group building the 32bit Board and we are considering using the Olimex active electrode design, found here, but have some questions.

If you are looking for solder yourself kits, I think Olimex has OpenEEG boards. They also sell assembled units.

You also would likely not need all 8 channels. Have you looked at the OpenEEG kit from Olimex?

Building an OpenEEG is a hard way to go. The Olimex unit is inexpensive and a good alternative until the Ganglion arrives. Take a close look at the Muse, there is a lot of support for it on various ap

Olimex has their OpenEEG system for 99 Euros, and active electrodes at 9 Euros each.

We have used the Olimex active electrodes with great success by powering them this way. 

Also I think the AE I built may have broken eventually. So the improvement (proposed by Joerg and now sold by Olimex) may be well justified. As I recall its primary purpose was ESD protection.

The Olimex AE design uses TL062 op Amp. There is a graph of equivalent input noise on page 11 of the DShttp://www.ti.com/lit/ds/symlink/tl062.pdf

I see @jarek had a hand in this as well. Jarek do you have any comments on the circuit board that Imec is using (image link previous post), or the TI 2272 op amp? This all looks pretty sweet and doabl
