I have no way to guarantee that values of the signal would be unique in anyway
My instructions were obviously unclear, I'll retry in the original post, have a re-read please.

balanced logistic train station
I can imagine quite a few different things one might describe as a balanced logistic ...

I want to iterate through a collection of signals, but I can't find an elegant way to iterate if many signals have all the same value. Sadly the special signal "Anything" isn't an output.

Example: Input=10 of all signals
Output= any single one of those
I could even do if the output isn't ...

I'm still trying to get my head around XKnight 's solution, but there appears to be a small bug. Input signals with values < the value associated with the selected constant, (output by the each = red combinator) output from the final combinator with values of 2.1G. So for the iron chest as you set ...

Your Variable Signal Delayer 2.0 is terrific. I'm wondering if you could provide a flowchart of how you would change it such that the timer restarts with each new input signal, only releasing the delayed signal(s) if it can reach the set time delay without receiving any new signals.

I've come up ...

Perhaps that's the more correct description. Circuit that takes everything as input signal and outputs anything.

You can do the "for-loop" filtering right now, but it's too difficult, and it takes an unknown ...
