the digital parts will run happily, though it's hard to tell for how
long, as the voltage drops. For the analog section we can let digital
ground be -2.4V and digital VCC +2.4V. If we need more than that,
it's possible to add two batteries at the 'ends' to achive +/- 3.6V,
more than enough for a lot of opamps. What do you think about that?

photo or mag stim parameters. It acts as sort
of a neuro-mantra. Kinda like feeding the brain
back on itself, to garner its own attention.
Until the patents happen, I can't say anymore.

There are no `real' adjustments, on the standalone
unit; just LED/MagStim intensity adjustments. Your
personal EEG context sets its feedback parameters.
