HOW ABOUT WE CALL THEM "F.I.S.H" an acronym for "fetal intellegence
surrounded H2o" or something cool.....then we call the "land dwellers" ,
"photovores" ???? hows that? or how aout we call the under water ones just ,
simple : FISH?@?!?!?!?

13168 Sat, 8 Apr 2000 00:44:05 EDT box beam@sgiblab.sgi.com SkavenArmy@cs.com say i get a 1' square peice of that reflective glass schtuff....amke a 1'
square box , wouldnt it be dark in the box no matter what because it just
keeps absorbing light(mini blackhole maybe?) or woudl it stay light in the
box 24/7.....cuz it would just keep bounsing around,.....right?OR would it be
extremelyhot in the box cuz of the light reflecting of each surface......??

just some more thoguths

too sure how to implement it using BEAM circuits though ~ but ~ I have a
small BOT I made for a grade in microprocessor applications.

The Sharp GP2D05 infrared sensor module,

http://www.acroname.com/robotics/parts/R21-IR05.html

is a great package for sending out an infrared signal and receiving it all in
one tidy package without no messy adjustment or supplying the proper freq.,
etc. ~ it is adjustable for range from 10 cm to 80 cm. ~ it si also a low
voltage unit ~ 3 vdc

it works basically like this:

You apply a high pulse for 3 milliseconds to clear the electronics in the
package ~ then change state to a low to start the detecting process for
approx. 30 to 40 (i used 32) milliseconds for it to stabilize ~ at the end of
that time you read the output from the sensor module ~ if it is a "low
output" an object was detected in its visible range ~ if "high output"
nothing there ~ I used a basic stamp for control and timing ~ and two units
pointed approx. 25 deg out ~ the beam or detection area is basically a cone
shape or more like tear drop shape ~ I experimented a bit with it and came up
with the optimal angle from center so that the modules would overlap in the
middle giving me an indication that something was straight in the bots path ~
i.e. both modules gave a low ~ I then wrote my basic code to avoid an object.
~ plane and simple ~ but it got me an "A" for my grade ~ thats all that
really mattered to me. ~ LoL

I also did the same with the handy board in assembly code.

Sorry to nit pick but yes you can contain light... laser technology... Just
not in a simple "glass cube"... Sorry just had to speak up...
