It's really difficult sometime to run multiple cables carrying different packet size into walls, or into a really compact contraption, expecially when u need also redpower tubing and blue/red wire...
I thinked at a really compact solution for make 2 separated EU lines cross each other without strange twirls around colored wires and things.
A cable that act like a crossroad for EU: the Cable Node.
EU coming from the left, will be outputted only to the right and viceversa.
EU coming from the front, will be outputted only to the back and viceversa.
EU coming from the top, will be outputted only to the bottom and viceversa.
The Node can handle 512 EU/t and have a 0.025 EU per block loss (like a glass fibre cable).
Is crafted like this :produces 4x Cable Nodes
Hope will u like it
