Just in time production

[ray4ever]

With the addition of the combinators I tried to put only the needed items on the belt that are needed for its production.
So for a standard circuit assembly in my case i would need 3 copper and 2 iron to produce 2 circuits each production cycle. The key point is the implementation of a resetable loop which is counting upwards. Based on the current iteration number all smart inserters can be controlled.

As seen above, at the start of the production cycle all products and initial ingredients are put on the belt and later picked up by the inserters. The amount of items put on the belt is controlled using the timer, only giving enough time to put 1 or 2 items on the belt.
With changing the reset signal you are able to adjust how many items you want to make within a given time.

In the last case the constant combinator provides signal 0 (=1) and signal 1 (=60). The decider combinator is set to signal 0 < signal 1 --> signal 0. With the output of the decider wired back to its input you get counter that is resettet when signal 0 = signal 1.

Can you explain this more or is there a savegame who we can look at it?
Thanks
