a data logger from a Casio graphics calculator
that common classroom calculator into a data logger for use in Science
Most New Zealand High Schools permit
students to use Casio FX9750g graphic calculators in mathematics. The
calculators become a data logger if connected to a PICAXE
microcontroller chip. Imagine the uses in junior Science, senior
Biology, Chemistry and Physics!

the Mobile Technologies in Science (MOTIS) and Computer Algebraic
Systems (CAS) research.
robot: an autonomous Mars Rover
type vehicle that can also be controlled by the arrow keys on the
CASI ... the Casio
controlled Mars Rover model
" The robot was put together
in the shed, an old tamiya bulldozer kit (10+ years old, hand held wire
linked remote), chasis modified to RF control and fitted with a dual
motor gearbox and I put in a L293D motor controller. The cover is a
piece of plastic box downpipe as the picture shows. The Casio sends a
keycode to the attached picaxe RF transmitter, the robot just responds
accordingly with its picaxe RF receiver. Nothing special so didn't take
long to make.
I added a SRF05 from one of
prototpye physics sensor units to the robot so it can't be driven on
purpose into obstacles. Robots are dumb but they don't have to be
stupid! It will explore the room if it hasn't heard from the Casio in a
while. My Calculus class is using robotics as a context for a
particular part of their course this term so wondered if I could throw
something together for them to use next week. It is very stable
climbing over feet, books and marker pens. We'll use CASI to make some
calculations and have some fun as well! "
Michael was awarded an eLearning
for 2008 to continue his work with mobile sensor technology and
interactive games. He has developed lesson plans and
experiments for the Casio /
PICAXE unit suitable for Science and Mathematics.
Michael has used sensors of his own design successfully with the Casio
and PICAXE system including
(distance and velocity)
in LIST1 and LIST2 can be analysed using the STATS functions and a best
fit curve chosen to determine the relationship between variables.
