+description: <<-END
+The pulsating chipset is used to add an autarchic pulsar to a gate (e.g., to convert a [[Basic Gate]] to a [[Basic Gate (Autarchic Pulsar)]]). Such a gate, when placed on a [[Wooden Transport Pipe]] or [[Wooden Fluid Pipe]], can produce two additional affects: a "single energy pulse" and an "energy pulsar".
+
+The single energy pulse will cause the pipe to extract a single unit from the adjacent inventory (whether a chest or tank). Each time the condition becomes true, another energy pulse will fire.
+
+The energy pulsar works similarly to the single energy pulse, but fires continually while the condition remains true. This makes it ideal for creating auto-emptying chests or tanks as it takes up much less space than a redstone engine.
