A repeater is a fluid logic device which creates a neverending cyclic on/off signal. Several designs are possible, and they can be made to operate at varying rates.
One example repeater (described on the forum by AncientEnemy) is as follows:
≈≈≈≈≈ - river or brook ═╗≈╔═ - wall to channel out after construction ╠╬╣ - fortification (to filter out any creatures inhabiting your river) ╠X╣ - shutoff floodgate (linked to convenient lever) ║#║ - 1-tile raising bridge (linked to pressure plate) ║^┼ - pressure plate (set to 7-7 water) and access door ╠X╣ - floodgate (linked to pressure plate) ╚═╝
This repeater toggles fairly slowly, about once every 200 steps, making it suitable for operating bridges, floodgates, and upright spikes. As an added bonus, the bottom wall (immediately beyond the floodgate) can be removed and connected to a cistern whose water level will be automatically maintained at a level between 3 and 4 deep.
