That would be the next step. However I must admit, that until now I
have not really started with the layout.
(Some of the elder parts done by Moritz e.g. connectors and filter
stages can be reused BTW)

Are there some ready-to-use circuits, I simply can cut and paste ?
What sensor type is best (sensitive and fast) for temperature ?

At the moment I do not know, if the board space on the amplifier pcb
is sufficient for this add-on.
However due to the fully modular concept it should be no problem to
design another pcb for temperature and GSR that is compatible to
the openEEG bus system
