I calculated the acceleration of gravity once with a light sensor, touch sensor
(for timing purposes), a ruler, and ROBOLAB 2.  It didn't involve a whole lot
of data so it didn't make it into the Sample Projects of ROBOLAB Investigator,
but some other ones that did are:

1) Calculating the speed of a LEGO motor (both with angle sensor and light
sensor and spinning black and white wheel), 2) graphing temperature and light
overnight outside my apartment window, 3) "reaction time" (like you described),
and 4) "doorway" (monitoring who comes in and out of your room with the light
sensor).  All of them are fully functioning examples with graphs, programs,
calculations, etc.

Incidentally, in my book "Creative Projects with LEGO Mindstorms" there are
several non-robotic projects, including 4 kinetic sculptures, a bird feeder
that automatically takes a picture of a bird that lands on it, and various
science experiements like a repeat of the doorway experiement, taking data
inside the refrigerator (light and temperature), and calculating speed and
acceleration of a robot, and calculating speed of a motor.

other things in the book that aren't the standard robot: Decoder, tickle-me
lego robot, elevator, and "painter" (robot that drives around and drips paint
on the ground at programmed intervals and places)

Hello,

Over in k12.ed.science a poster wanted to perform an experiment where he
would time how long it took various objects to fall when dropped inside
a long tube. He was looking for information regarding timing circuits,
how to build one, where to get the parts, how to read the time values,
etc.  It's an experiment I've thought of doing myself using the RCX to
do the timing. I recommended he look into getting a Mindstorms kit and
using the RCX. As an added bonus once he done with the experiment he
still has the RCX and Mindstorms.

Lately I've been looking at non-robotic uses of the RCX. One experiment
we did over the summer was  timing a persons reflexes. We connected a
pushbutton to the RCX, programed the RCX to play a tone after a random
delay and then  recorded the time it took for a person holding the
button to press it.  The kids had a great time with that one trying to
beat each other. It might even lead to a science fair project.

Anyway I was wondering how many of you are using the RCX in this way?
While robots are great both for fun and learning the RCX presents a
great many other possibilities.
So what else is the RCX being used for?

regards
