Hi all,
I have an WaveRider CEO, a one channel EEG.
The electrodes are little cups, they are plugged in
the machine with one plug, that is, three leads, one
for the head, two for the ears, into one plug. The plug
(i don't know the englisch name) is like the plug on
the cable of your modem.
regards,
Frans.

This is a good point. I also was concerned about the potential for
mis-use of RCA connecters or whatever. The industry has gone to an
FDA-approved shielded-pin connector for EEG electrodes. I don't know
how these would work with the shielding issue. I emailed the HAL4
people and asked about their sources for electrodes or instructions
for building their electrodes, and will make a posting when I hear
from them.
