- v50 information can now be added to pages in the main namespace. v0.47 information can still be found in the DF2014 namespace. See here for more details on the new versioning policy.

I've put together a few fluid logic circuits using doors (because they react about 100 times faster than floodgates and bridges), and NOT using hatches (because I have trouble preventing them from letting overflow through, especially when the water is pressurized). These setups are awkward to initialize, but once you've managed that, they can do some interesting things.
The "Clock Toggle", as I'm calling it, causes its output to toggle only when it receives an ON signal. OFF signals are ignored. This could, in theory, be used to build a clock, although I've only built one so far.
This was my first quick design for a door-based repeater:

Little-known fact: pressure plates react instantly when their ON condition is met, but require 100 continuous steps of OFF conditions before sending an OFF signal. So the design above doesn't work as desired, because the red plate doesn't close the red door fast enough.
The design I'm fiddling with now uses a hatch, and requires a drainage system, unfortunately:

Where ┼ turns the oscillator on and off, and ^ is linked to hatch ¢ and door ┼. Seems to work, with a period slightly over 100 steps, but there's some variability due to the water flow, so I'm fiddling with the drainage system and pressurization.
Actually, the fastest repeater I know of (and the easiest to set up) is "Pull the lever" on infinite repeat. I get about 1 pull every 5 or 6 steps with a perfectly agile dwarf, meaning one OPEN signal every 10-12 steps. Too bad it requires a dwarf.
