you can go even smaller if you're willing to sacrifice some resolution(and CPU cycles)
could probably use a log scale instead of the arbitrary thresholds but that would take some thinking

This last one was very handy for me as it's not so big (all appreciated, mind!) and I have tweaked it in a small way to show what is being counted, so if anyone finds that useful (a bunch of these in a row, perhaps), here it is:

this does not work for showing content of the logistics-network though as its only showing the first item there then

You can use a Selector Combinator (which are new for 2.0, and finding new uses all the time!) in either Select Input or Random Input mode to filter the signal, ideal for showing contents of a Mall, one item at a time.

Good Luck!

Thanks, this is super helpful! Is there a way to change what is being displayed/counted aside from at the original paste-in?

sure there is, combinators are turing-complete after all
just have it display a dummy signal which you set however you want

I modified SuicideJunkie's design to include negative numbers. I also included the missing 10th digit. It *does* require an extra DC + CC, but that's the best I could do...

Also, I modified ctalkep_'s bp to include negative numbers. Not incredibly accurate, but it at least gives some indication of the range of the signal...

One math combinator, one lookup table digit-basing constant.
And one input constant.

Now with leading zero removal and parameterized input signal choice.
But what if I need that last 2147483647??? This display can only go up to 2147483646, and only if you add another display to the left...

:) :) :)


Too bad it only supports signed 4-byte longs...

I revised my lamp-based number display and added a few new ones for Factorio 2.

For the lamps I ended up improving contrast using the new color features. I needed an extra stage of combinators to support that. 4 gate delays, horrible! Otherwise, it’s mostly cleanup using new combinator features. Processing red and green inputs separately is nice. I used to use horrible hacks to get more functionality out of fewer combinators. Want to check if -10<x<0? Add 9-2^31 to the other wire color, then check that x<9-2^31. Want to output 10 if x=0? Add 10 to the other wire color, then check that x=10 and output the input value. You can output an arbitrary constant now, but you still can’t see 0 using wildcards. I worked around it differently this time.


The new panels are so very clean and compact! I swear I came up with this solution before checking prior art. I guess there aren’t many options once you’re down to a single active combinator. I will say that I solved the range problem. It supports the entire [-2^31, 2^31). 1 gate delay.


One of my ideas to make a more compact display was to use electronic color codes. Factorio 2 enables that as well. But it’s easily overshadowed by the more compact panels showing normie numbers. The = combinators can be shared among multiple instances, though, if you reconfigure the internal signals to be different. I improvised a pink lamp as a minus sign. 3 gate delays.
