Minecraft wiki entry for Pulse, associated text: Used purely as a pulse divider or counter this circuit is somewhat inefficient, since it would have to be stacked nine times to be able to count almost as many pulses (512) as the dropper-dropper divider. However, the stacking binary design means that the pulse count value can be easily read out by simply taking an output line from each stack element. In combination with OR or NOR gates, this can be used to trigger an output after an arbitrary number of pulses, or to create a divider for any number when combined with the reset circuit below.
