I was taking a look at Asynch from TurboPower...now Open
Source...and it seems that it wouldn't be difficult at all to handle simple
asynchronous instructions via a serial port or even USB w/serial adapter.
My question has more to do with hardware than anything else.
What I'm attempting to do is write my own program for handling very
simple bio-feedback data. What this entails are one to x number of
lightweight micro-volt sensors which are affixed by adhesives to various
points on the body, ( usually the forehead, mandible, or temples, and in
some cases fingers and/or wrists ). A battery operated computer board which
I'm building from supplies readily available at Radio Shack, measures the
changes in resistance between two or more of these paired contact sensors
and emits a signal which I then wish in turn to read and show via visual and
auditory feedback. This will be accomplished via a retentive scope-type
display that plots a graph, a single point visual which moves up, down,
left, and right, in its response to the same signals, as well as a user-set,
continuous sound that travels up and down the scale in relation to the
signal. The data will also be saved and stored as a stream in a local
database for re-play and analysis.
Secondary to its uses for personal bio-feedback will be the ability
to provide variant wake level cues via sending micro-shocks back thru the
sensors to the person's skin at pre-programmed and AI-controlled intervals,
( in response to dynamically measured sensor data ), for lucid dreaming
experimentation, and pain control.
Not being an electronics wizard myself, ( the most complicated
electronic device I ever built was a specialized light-meter for measuring
grey values as used in the Zone system during darkroom work on b/w
photographic negatives ), I have a friend working out the hardware design
for me. Unfortunately, he is has unknowledgeable about computers as I am in
electronic control and measurement systems and so I need to find out the
signal characteristics this hardware can submit via the serial port, as well
as what it can expect in return!
So I was hoping someone who has some experience with these areas
might be able to contact me off-list and give me a few pointers in this area
so that I can then in turn ensure the hardware handles the necessary
signals. If so please contact me at the e-mail address below:
