This is neat, and as someone who wants to eventually build a layout in his basement I'm glad there's continued development of these types of projects, but I'm not sure I see how this is going to be simpler than DCC. The complexity of programming DCC is called out, but reprogramming and designing an "infinitely variable" Arduino based solution is almost certainly going to be way more complex
Maybe that complexity is the selling point, in that you may be able to do things DCC can't, but approaching this as easier than DCC seems off base
Would this have any advantages over trams, though? I can think of one disadvantage: rails would be higher than the road, disrupting cars and bicycles, whereas the grooves that trams follow can usually be crossed by cars or bicycles.
I thought Lego discontinued their train stuff... surprised to see it is still going.
Do you source real Lego or the Lego-compatible knock-off stuff e.g. Lepin? I'm not much of a lego guy, but I would think at house-scale it would get cost prohibitive pretty quickly to use genuine Lego unless there was a compelling reason to e.g. I don't know if the knock-off stuff is as structurally sound.
Lego seems to continually discontinue the trains and then release a new version with slightly different parts. Thankfully they tend to be backward compatible (but not always forward).
And no, I use real Lego parts. There is a huge quality difference, especially against lepin
