I was thinking about creating a spiked hallway, but I don't want a hallway of spikes that just went up and down, no, I want a hallway where the spikes alternate like this
Before:
^+^+^+^+^
After:
+^+^+^+^+
The spikes simply alternate, but it isn't really simple, because I want to do this with one lever. The solution, this:
View from side
______
| %% |
|^%% |
|WWW_|
What is this, this is one part of it, you need two of these, the first is connected to the first set of spikes, the second one to the second set. How does this all work? Simple, the pumps don't transfer power to each other, and instead they get their power from gear assemblies, to the side. Gear assemblies toggle, instead of the levers simply sending on/off signals. When the lever goes one way, the top is off, the bottom is on, the water goes to the left, and the pressure plate is activated, making the spikes go up. In fact, you don't NEED two, you could put another plate in that small hole on the right side. I think this is a simple and small way to turn any trigger into a toggle, if it works.
In order to set this up, dig it out, build the plate, hook it up, and get 7 water in the small hole on the right. After that build the pumps, and the assemblies. Now then, hook the lever up to ONE of the assemblies, then pull it, then hook it up to the other assembly, the assemblies are now opposite of eachother and will toggle seperately, making the pumps toggle.
If this works, it will be a large advance in what we can do with levers.
TL;DR: The design turns an input into a toggle for anything.
