I usually just delete things like this, you know "FREE" etc.
But this kind of caught my eye.

No popups or anything, but if you don't want to go, let me explain what
it is. It's a black plastic box, that has a few pot dials (They could
be Resistors), and 5 jacks. Basically, you put a 9 V battery in this
device; plug these electrodes that hook up to the jack. You put one
jack in one ear and the other jack in the other ear, after you put on
the gel of course.
Supposedly, like a drug, it stimulates the pleasure centers of your
brain.
Being a skeptic, I want to ask if this is safe. If so, why does it
work? Reason being is it would be an interesting experiment trying to
detect changes within your brain with a set up like that. Anyone know
any kind of scientific studies, or good resources about brain
monitoring?
Though, being one of the smart class, I am not stupid enough to try
something that isn't even tested by the FDA:P I mean even if the
current and voltage is safe, the idea that you purposely pull something
between your ears make me nervous.

usually to cure some ache or pain. The only "pleasure" resulting from
this box derives from the inventor depositing your check. It sends a
few microamps of current through your brainstem, with subjective
sensations of floating, vertigo, and sometimes nausea. This occurs
because it affects the "vestibular system", or sense of balance in the
inner ear (i.e. semicircular canals and gravity receptors). If you like
being seasick, you'd love this device. Is it safe? Depends on the
circuitry. Any diagnostic uses for testing the vestibular system use
both current-limiting and minimal exposure time.

thing I thought was the fester machine at arcades. You hold two of
these metal rods, and see how long you can hold on before the electric
current gets to much:P
Still, brings another question. How can you monitor brainwaves then? I
know doctors put on electrodes to your head. Is it as simple as just
plugging in an AD converter? That's where I was really going with this.

stuck on your head to monitor brain activity. They spent about 1.5 hours
gluing God knows how many electrodes on my head, chest and legs.
I think Velleman sells an EKG kit -- this would have similar circuits
although probably with less gain.

configurations for different kinds of brain activity. They are only a
few microvolts in amplitude, and embedded in noise. Electrodes with
conductive gel are used. Signals are amplified with FET-input preamps,
and then cascaded amps for an overall gain of about 1M. Bandpass
filters are used to isolate the signals into narrow bands, such as
'alpha waves', etc. Signal averaging is used to extract signal from
noise. This works well with 'evoked response' brainwaves: responses to
a repeated stimulus such as flashes of light, loud clicks in the ear,
etc. For example an Audiometric Brainstem Response (ABR) will be
recorded from a few hundred clicks from a headphone delivered to one
ear, with each click separated by about 10 msec. Recorded signals will
be averaged by cumulatively summing a 10 msec epoch following each
click. This allows the auditory response signal to 'grow' out of the
noise. Similar methods produce Visual Evoked Responses from flashes of
light.
Recording brainwaves could be done safely with hobbyist equipment, but
only if isolation amplifiers and current-limiting resistors are used to
protect the human subject from the possibility of current delivered
through the electrodes. The FDA and UL have specific requirements which
must be met for those of us involved with medical device R&D.

Heh, hey I got some mater between my ears on that. I mean the first
thing I thought was the fester machine at arcades. You hold two of
these metal rods, and see how long you can hold on before the electric
