I experimented with logic gates and haven't found this on the wiki so I thought to share...

You need a stream and a drain but no power source or pump.

Key:
W:Wall
X:Floodgate
B:Raising bridge
+:NO pressure plate (set to trigger at 4-7)
-:NC pressure plate (set to trigger at 0-3)
D: Drain

Code: [Select]

               AND      NAND     OR       NOR       XOR       XNOR

               ~~~      ~~~      ~~~      ~~~      ~~~~~      ~~~~~
               W~W      W~W      W~W      W~W      W~W~W      W~W~W
Input 1    ->  WXW  ->  WXW  ->  WBW  ->  WBW  ->  WBWXW  ->  WBWXW
Input 2    ->  WXW  ->  WXW  ->  WBW  ->  WBW  ->  WXWBW  ->  WXWBW
Output         W+W      W-W      W-W      W+W      WW+WW      WW-WW
               WDW      WDW      WDW      WDW       WDW        WDW
I haven't tried it but I suppose you could replace the floodgates by doors and the bridges by hatches covering a drain for a faster reaction.

Have fun.

My work:

I've also made an 8-bit one around the time of this thread, albeit it was water powered and built like this:

Reservoir of water
Logic gates
Drain

It basically went like this:

Spoiler (click to show/hide)

Reservoir of water
Logic gates
Drain

It basically went like this:

Code: [Select]

~ = water source (via channel from above)
X = Floodgate
+ = drawbridge
# = wall
^ = pressure plate (triggered by 4-7 water)
_ = drain (channel)
. = floor

Inputs are via lever/plate signal to the floodgates/bridges

AND:
#######
#~XX^_#
#######

OR:
 #####
##.X.##
#~.X^_#
#######

NAND and NOR are implemented by using bridges instead of floodgates.

XOR can be done using a NAND, an OR, and an AND, but I found out this nice setup:
A = floodgate connected to input a
a = bridge connected to input a

 ######
##.aB.##
#~.bA^_#
########

Also, your OR and NOR should be switched.

[Shivaran]

Also, your OR and NOR should be switched.

You're right, fixed.

[Quatch]

What's linked to what there? are the inputs fluid, or levers to the various bridges and floodgates?

[Quietust]

Ihe inputs would be levers or pressure plates linked to the bridges and floodgates - the sole purpose of the water is to translate the input signals into output signals.

[Mechanoid]

Diagonals don't translate water pressure. Your XOR and XNOR are faulty in this regard. The situation could be repaired by removing the V shape and making it a strait line, like so:
