I've read this whole thread, and still don't the 'point' to this. What can it actually DO?
Well, the design described in the OP is a repeater that toggles a door every single tick.
The design described
here is proof to the following:
If, in a parallel DF universe where pressure plates don't delay, you can build a logic device that satisfies these conditions (copied from there):
- The computer may only use two dimensions, one horizontal and one vertical (let's say Y and Z). The computer must use exactly one layer in the X dimension.
- Pressure plates all trigger on 7/7 water, but not on 0/7 [...].
- Water is not allowed to fall, water must move downwards by teleport pipes.
- All energy powering the computer must pass through a single gear assembly (the "power assembly") that is not used for anything else, and pre-toggled to be disengaged.
- First the screw pumps, then the gears and axles, then the pressure plates must be built. The gears and axles must be built so that from every screw pump, every possible simple (not self-intersecting) power path to the power assembly must be built in exactly this path's order.
- Every screw pump must be powered from the top.
- Information must be stored by having 7/7 tiles of water in some of many places, all called 'info tiles'. Pressure plates may be built only on info tiles. The information must be persistent, that is, if you shut off the power gear, the water must stay where it is.
- Every info tile must have an open channel into it from above. The info tile and the tile above have to be unable to transport power into the X dimension, Further, the tile above may not be an info tile itself or contain water.
Then you can, in regular DF, build a logic device that does what the parallel universe device can do, in the same in-game time!
The real-DF design will require about 400 times the number of screw pumps the parallel-DF design does, but who cares.
Also, I just thought of a way better lightspeed repeater design:
Side view:
Construction:
Expand this design vertically to have 100 cyan tiles. This time, build the object of togglance before everything else.
Build the pump stacks from bottom to top and a pressure plate on every cyan tile.
Connect every pressure plate to your buzzing object and put water into the yellow tile. To start/stop, connect/deconnect power. That's all!
