I am making an OpenEEG myself. I ordered two digital and two analog circuit
boards.

Each analog circuit supports two electrodes. You can connect up to three
analog boards into a single digital board (AVR AT90S4433 and ATmega8A
supports 6 ADC channels).

If you need more you could consider making your own digital circuit using a
better ADC IC and/or modern microcontroller.

You can also connect your analog boards to Arduino or a Raspberry pi with
ADC IC.
