style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Arial">I've ben using a free
software package from Festo called "fluidsim" to show how pneumatic circuits
work. It also has an electrical component as well as being able to put your own
logic symbols in a chip and build circuits. There is also a logic ladder section
to create timer circuits etc. The down side is the free version is only active
for 2 hours before it shuts down and you can't save anything but I've used it in
the classroom and it lets the students see how the valves work etc. Also on the
web site they have video footage of the aquajelly and the airjelly, which is
part of their "bionic learning". If you are lucky enough to get to the
DATTA Conference they should have some DVD's of their Bionic learning that
goes for approx. 9 mins. that is excellent footage. I'm looking at purchasing
some of their MecLab work stations. </SPAN></P>
