Is it possible to transmit the redstone power with a lever, vertically, and from top to bottom?
11 Answer
I assume you are using the lever to turn the signal on/off.
The wiki has a Vertical Pattern for transmitting the signal on it. For moving a signal from bottom to top it is simple. Put a torch on the stone the lever is one, then a stone above it with another torch upon that. It will scale up. For a down or up signal a 2x2 spiral is the next easiest manner in which to get a signal to travel. Note that depending on the distance you may need a repeater some where in the mix to get the signal to carry on.
Hope this helps
