That’s exceedingly cool. But since I don’t have an RCX, it makes me wonder
whether something similar could be done without it. Perhaps a small lever
that’s pressed by the train as it goes past, which is connected by a hidden
string to the heads? Or something that uses the weight of the train on the
tracks?
Probably not as easy or as good as using RCX, but it makes one wonder...
Anyway, super job!
