Reduce the size of redstone circuit

Solution 1:

this is not complete but here are a few hints:

• you can put the timer under the pulse former by putting a floor over it and putting redstone on the block where the redstone block is under and avoiding the other one

• you can combine the pulse former and pulse extender into a single circuit by extending the delay of the repeater (combining several if needed)

  the pulse former works because the pulse is formed when the repeater is still delaying the signal while the comparer already has it

• the torch can be on top of the block reducing it's size by 1 and moving the signal up

• if you invert the signal on the side of the comparator the output will be inverted (always on with a off pulse)
