Re: monkey rail

Thanks for the offer. I hadn't thought about the programming yet. STil 
need to watch your videos to see how yours works. At the moment I'm 
trying to learn NQC. I thought the whole setup might be controlled with 
a single RCX (as appears to be the case in the additional link you 
sent). Why did you use a second one?

I've counted 3 motors and 2 or 3 rotation sensors. I don't have any 
rotation sensors, but I'm trying to figure out if I can use 'Electric 
Computer Speed' (peeron #32467) by cutting the wire between the sensor 
and the 'computer and fitting it with an electric brick 2x2x2 from an 
electric cable.

I've seen there is an 'mrailprograms' folder in your brickshelf gallery, 
but it is 'not yet public'. I'm in no hurry to see the program (building 
the thing will take me quite some time), but I would love to have a look 
at your program  if only to get some ideas for an NQC version.
