Hello All,
After I bought Mindstorms last fall, I became intrigued by the number of people
wanting to drive more than 3 motors or have more than 3 sensors that is offered
by the RCX.
I took a different approach (unless I missed it in the archives), and,
admittedly, one that might not appeal to the RCX loyalists. This problem
looked like a good application for CAN (Controller Area Network). With
CAN, it is possible to drive any number of motors and sensors
independently. OK, there is finite limit, but you are more likely to run
out of money for motors and sensors before you exceed the limits of CAN.
I've posted it at http://www.flash.net/~mfabiny/C505brick.htm. This relates to
my job, but I did it more for fun than anything else. Take a look and see what
you think.
Regards,
Mark Fabiny

| I have to agree...EXTREMLY interesting indeed! Have you approached Lego with this?? I'm serious. A modular RCX would be Heaven-sent; it's the way they should have done it in the first place! :) I like your idea with having both a sensor & a port on (...)
