I've done the ladder, using slabs, but even though the button at the bottom triggers the powered rail at top, the button at the top won't power downwards. Is the only way to achieve this with the spiral?
it isn't far, like may 10 redstone, but a single button can power the distance, so there are no torches, or repeaters, or anything like. Just redstone and two buttons. i just want the circuit to go up and down.
I think it isn't possible in 2 wide. I think it is possible 4 or maybe 3 wide. Could that be useful for you or is the spiral better?
Edit: I've found a way to go up and down with in the middle 2 wide. It's really the most stupid and not usefull way there is but it works kind of :). It's just going up with redstone torches and going down with a dispenser and a pressure plate. Only at the top it's wider because the dispenser is placed in front. Otherwise the system what goes up will power the system what goes down.
