[Openeeg-list] active electrode construction

[H. K. <her...@gm...>]

Hi folks,

I'm looking at the active electrode diagrams made by Joe Street, and I can't
find:
1) where to put the resistor (as far as I know, without it the op amp would
work as a follower)
2) how to solder the op amp, since there aren't any holes for it.
Can anyone please help me on this issues? It may be simple, but I can't
figure it out.... I have little knowledge in electronics.
Thank you all for your support.
Regards.

Hernan
