Subject: [alt-beam] heads again
hi again.
after reading a posting to the list about using sound as a basis for the
inputs to a bicore head, i thought of a question that i had. I ripped apart
an old motion sensor lights, the ones that you put on your garage, and
inside was a piro electric sensor. i was wondering how you could fit this
onto a head so that it would follow people. the output is shown below:
_
/ \
-----------------/ \ --------------------------
| \ /

this is where the person first walks by, going from left to
right.
I don't know if that helped any, but it was thinking that mabe we could use
the wave form to somehow only use one pyroelectric sensor. I don't know
though.

PS a long time ago there was a posting to the list about how to convert asci
schematics to normal format. does any body still have that letter?????
