This is a device that makes the signal from a button last longer. this is useful for making cart callers and the such, and later if i get 3 comments ill make an instructables showing how to make an fully automatic arrow cannon with it.

Step 1: The Split

The in put must split to make to paths also the signal can come from any where not just a button. it can come from as far as you want a long as it hits a repeater so it has power to get through the circuit.

Step 2: The Delay

The delay make with 2 Repeaters.

Step 3: They Come to Gather

Make them merge it should look like it dose in the pic.

Step 4: If It Wont Work

If it wont work you need to add a repeater to the free wire like in the pic.

The diode on he out put i also needed.

Step 5: Last Call

To make the delay longer just change the levers on the to delay repeaters.

Hmm, arrow cannon. I know how to make one. It's easy. I'll make an instructable on it.

:D good instructable, by the way

Unfortunately with this design, the max delay that you can have is the duration of the original pulse (meaning the total delay is double the original pulse). A much more flexible design would be making a monostable circuit, with the amount of repeaters leading to the reset equal to your chose delay.
