Fractional collecting makes the timer much more powerful in a small footprint. First, the timer is on one leg of four making the starting point 25% of the total. Then, by using the equalizers, we can decrease the number of counter beans needed.

From 25% we halve it 4 more times. So it goes from 1/4 to 1/8 to 1/16 to 1/32 and finally to 1/64 of the total collected. The bottom Storage ends up at 15/16 of the other 3. The trigger takes only 1/16 away from the 25% on that leg. When released, the collected parts are dumped back into the leg from which they came so everything flows nicely.

You can see the count on the Storage units relative to the number of counter beans. About 3 more parts in the counter and this will trip because it will back up into the Storage, go out the non-default, and trip the Belt Reader. That will give about 400 parts times 4 belts. That's enough to make the required rate for level up plus enough to flush old parts from the MAM for a quick changeover. (MAM redesign in the works.) To store more or less just change the size of the collection loop remembering that 1 part in the counter will equal 16 parts in each Storage unit.

Belt Readers are the sensors used to make this work. In an idle state, they will signal 0. When something passes through, it signals 1 for a short time. So, we will cause parts to backup to a Belt Reader to start everything.

Belt Reader - 6 is the trigger. It starts the dump. All the other Belt Readers are the keep-alive sensors.

Belt Reader - 5 is the final keep-alive sensor just before the junction near the hub. That allows the belts to empty fully before resuming normal operation.

OR Gate - 5 is the final decider and driver of the filters. It senses Belt Reader - 6 (the trigger) on one side and all the other belt readers (keep-alive) on the other. This is where the signal 1 comes from to open your filters and let the flood begin.

(The hub is just out of site at the top of this image.)

Parts are storing and will trigger a dump soon.

Note the "PART STOPPERS". These throw away anything that does not match the signal on the hub bus. At some point during the dump, when throughput is achieved, this will change and these will trash everything else on the belt. You always need this to keep your containers clean.

Dumping has just started. Note that the belts above have been stopped and the trigger is emptying.
