Tutorial:Sculk mechanisms

Water washes away redstone, so it may not be obvious how to do this. The trick is to place a comparator behind a conductive block. See schematic.

A limitation of sculk shriekers is that they shriek for 4.5 seconds, that is, 90 game ticks (gt). That is too infrequent for some purposes.

The cooldown on a calibrated sculk sensor is 10 gt. Thus, theoretically, the sensor could click 9 times within a 90 gt timeframe. Realistically, that is extremely unlikely if not impossible, so let's say a practical maximum is 7 times that it could activate some shrieker every 90 gt.

If we assign four shriekers to each sensor (which is easy to build), then in practice, the system is very responsive. The sensor could theoretically exhaust all four shriekers within a timespan of 4*90/7 ≈ 52 gt, a fact which still imposes a minimum safe pulse length of ~38 gt at the outputs for something like opening a door, if we want the doors to be able to remain continuously open.

You can distinguish between at least two strategies for redstone transmission through sculk: calibrated/caseless and insulated/encased.^{[name pending]}

• calibrated is to calibrate each sensor to some locally uncommon vibration
• insulated is to wrap each sensor in wool, forming a kind of intermittent tube and relying on the narrow detection zone to filter out noise

Between every 14 empty blocks, build a 3-high blob of wool with a sculk sensor inside.
