Redstone Clock (Extra Utilities)

The Redstone Clock is a block added by which emits a  pulse once a second, or every 20 ticks. The block does not change visually when emitting redstone, nor does it emit light when active. It can be used as a cheap and space-saving alternative to a Vanilla redstone clock built with s, although its pulse rate is not configurable.

It will stop working if activated by a continuous Redstone signal - attaching a to the Redstone Clock allows easy toggling.

Applications
The Redstone Clock is well-suited to automate a, as its redstone pulse can be extended to activate several s at once. Other applications for the Redstone Clock include the or the, the latter of which can be used to build an early-game automatic  generator.
