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.
