Timers

Timers are mechanisms that once activated, keep sending an activation signal to the wire they are connected to at regular intervals.

Timers can only be placed on top of solid blocks.

They can be toggled on and off with a right click like a switch.

Upon reload of world all timers become inactive.

If a faster signal is needed, one may use a Crab Engine

An even faster method is using a bird engine. Check out http://www.youtube.com/watch?v=0KNjVhOhh6w&feature=plcp&context=C48a7210VDvjVQa1PpcFNVWABjITx9GqIRMDOFVhCgHEdYBe45FC4= for how to make.
