Hey guys
This is rastus22 and I am going to be talking about the monostable circuit today. A monostable circuit is basically a device that will shorten any pulse, usually to a one tick pulse. These can be very useful especially in a T Flip-Flop because if a stick piston is pushed with a one tick pulse it will leave the block out there like a normal piston but it will bring it back next time it goes out. Now I'm going to teach you how to create a monostable circuit. You are going to need:
One repeater
Two redstone 
One sticky piston
One button (Optional)
Six of any block (I think)
First Place 2 blocks one on top of the other.
Second put the button on the top block.
On the opposite side of the button place a block with redstone on it.
Place a sticky piston with a block on top of it after the redstone.
Place a repeater with a block under it leading away from the block on the sticky piston 
Place a  piece of redstone after the repeater and your done.
