I'm not sure how 'exactly' I can describe the system but I'll give it a try. I'll basically describe how the scripting system is used and you can infer how the code must work. First of all, let me talk about the marker tape pieces. They come from a (...) (20 years ago, 17-Oct-04, to lugnet.org.us.smart)

How exactly does the scripting system you use work? I'm trying my hand at this, and did not think of using the remote to "program", so you've got my curiosity arroused (I'm using NQC, but that still gives me program access to three buttons (...) (20 years ago, 16-Oct-04, to lugnet.org.us.smart)

David, Thanks for the input. I think the goal for the Great Ball Contraption will be different from your Crate Contraption for a couple reasons. For example, I don't expect this to run constantly. I'm hoping we'll be able to make it work for (...) (20 years ago, 15-Oct-04, to lugnet.org.us.smart)
