That 2-part divide all is really clever! And the 2-dimensional array lookup is great too. There is no way I can improve the logic, the best I can do is make it look pretty.

This blueprint does not require any wiring. The 3x3 loader can be removed when everything is working.

I think we can write own "Digit display history":
Book
This was the cool history of the nice challenge.
153 combinators in the beginning vs 21 combinators in the end.

I improved my loader a bit more, it now uses a checksum to avoid corrupt data.

This is my version of makining it look pretty! By moving everything to the top and adding substation you can make the didgets clear from wires :)

Putting the wires on top does look nicer, if you don't mind an extra tile of height.

Merged both Digital Display topics in this subforum as they are about the same topic.
Some users already posted their creations in both threads anyway :lol:

In case anyone is curious about how this works, I sort of reverse engineered DaveMcW's single-digit hexadecimal one from two posts earlier. These were my notes.

I don't know what the purpose is for adding 100 to everything. It works just the same without it.

Thanks for the updated version! I just found this thread today and was dismayed at the problems I had using the blueprints here. Only one problem with your version: when you remove the left-most decider to enable leading zeroes, it breaks that green circuit.

So, instructions for enabling leading zeroes: build it disconnected from power; remove the right-most Constant Combinator; remove the left-most Decider Combinator; add a green wire connection between the top ends of the two Arithmetic (+) Combinators to the right of the Decider you just removed (output of the first one to input of the second one).

Yup, thanks for that, I am now able to see at a glance how many of which ores I have available in the system (see below). Note that there is actually 5 digits on the first display, but somehow only the first 3 got captured on the screenshot... That's kinda odd, but they do display properly ingame. So this is my unloading station, and it tells me how many items I have in the requester chests that get loaded by the unloading robots.

Now here's mine display:
Image
It's the Fixedsys font (all but the "0", I let the "/" out for saving one combination, else the 0 would take 32 different lamps), and i've orientated me on the existing 8-block digits, this one has 45 different combinations of lamps.

I don't know how to post the blueprint string, can someone explain me, how i can post it?

Neverthemind i try to explain it:
In the normal digit blueprint you have 1 combinator for each number, for my version you need 2 combinators for each number, so just stretch the combinators to the left and right and connect both combinators.

then fill the combinators for each number with the following output signals:

For Items you could chose what you want (except colors), i just ran out of numbers and characters

0: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, D, E, F, G, H, I, J, K, L, M, P, Q, R, S, T, U, V, W (for getting the "/" in, add also B, C, N and O, but then you need 3 constant combinators for the 0)
1: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, B, C, X, Y, Z, Item1, Item2, Item3
2: 0, 1, 2, 3, 4, 5, 6, 7, D, E, F, G, H, I, J, K, L, M, N, O, X, Y, Item4, Item5
3: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, D, E, F, G, H, I, J, K, L, M, P, Q, X, Item6
4: 0, 1, 2, 3, 8, 9, D, E, F, G, H, N, P, Q, R, S, T, U, Z, Item1, Item4, Item6, Item7, Item10
5: 0, 4, 5, 6, 8, 9, D, E, F, I, J, P, R, V, W, X, Item2, Item5, Item6, Item8
6: 0, 1, 2, 4, 5, 8, 9, B, D, G, I, K, L, P, Q, R, S, T, U, V, W, Z, Item3, Item7
7: 1, 3, 4, 7, B, C, D, E, G, I, K, M, N, O, X, Y, Item6, Item8, Item9
8: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, D, E, F, G, H, I, J, K, L, M, P, Q, R, S, T, V, X, Y, Item6, Item7
9: 0, 1, 3, 4, 5, 6, 7, 9, D, E, F, H, I, J, M, O, R, T, U, V, W, Y, Item1, Item2, Item9

the lamps have the following ">0" conditions:

I have something to show too.

BEHOLD the 10x10 matrix display, it is accesible through simple (x,y) points.
[img]
20161130191334_1.jpg
[/img]

Working:-
As you can see in image i have assigned coordinates 1-10 to each row and each column.
To illuminate point on row 5 column 10 the (x,y) will be(10,5).....x and y coordinates are represented by number of a specific signal..
for eg, in earlier case , in x constant combinator [any signal]*(10), and in y constant combinator [signal used in x]*(5),
Note:- >each point is represented by different signals.
>you can add more constant combinators for more points
>I cant find where the blueprint string is saved so , I am sorry.
>you can expand it as much as you want I made 10*10 for prototype, the limiting factor is the number of different signals available.

So, I tried building that amazing looking one, it took me from 36 FPS to 4... just thought I'd share a small giggle about my "potato computer". Can't wait for a better computer to use this...
Will code for Food. I also have 11+ mods!

So can someone explain how to use constant and decider combinators to create an alphabet?

Edit for specificity:

I understand that you have 1 constant combi for 0-9 and that it holds the signals you need to send to turn on each light. What I don't understand is how to use it as a lookup library for multiple digits. For example, if I want to display the number 123, I can separate the digits using the modulo method shown earlier. So I can get the digits. Now I need to send those to the library to figure out what signals it needs in order to light the correct lights, and now I have no clue how to deal with it.

That was something that really amazed me from XKnight's design, and it took me a while to fully understand how it worked. Finally I wrote a simple script to generate the signal alphabet and lamp configuration to embed an arbitrary character set.

What you want to see on the lamps can be represented logically as a list true and false values, for example if you wanted to represent the number 4 you could draw:

Code: Select all

1 0 1
1 0 1
1 1 1
0 0 1
0 0 1
and do the same for every other character you wanted to represent. That representation is in the spacial domain, meaning that for each character it tells you what lamps must be on.

In order to encode all the characters into a signal alphabet you have to transform that from the spacial domain into the signal domain, that tells you for each lamp what characters make it go on.

For example, let's do this transformation for the following 3 lamp configurations that want to represent the digits 2, 3 and 4 (I choose a 3x3 lamp array to simplify things):

Code: Select all

1 1 0    1 1 1    1 0 1
0 1 0    0 1 1    1 1 1
0 1 1    1 1 1    0 0 1
Now, for each of the 9 lamps, let's see if they are on or off for the 3 characters we want to represent:

Code: Select all

Lamp 0: [1 1 1]
Lamp 1: [1 1 0]
Lamp 2: [0 1 1]
Lamp 3: [0 0 1]
Lamp 4: [1 1 1]
Lamp 5: [0 1 1]
Lamp 6: [0 1 0]
Lamp 7: [1 1 0]
Lamp 8: [1 1 1]
That's it, now the information is in the signal domain, and we could generate the alphabet directly from this, but we can optimize things by removing duplicate signals. In this case we can see that Lamp 1 and Lamp 7 use the same signals, the same is happes to Lamp 2 and Lamp 5 and to Lamps 0, 4 and 8, so really we only need 5 signals:

Code: Select all

Signal 1: [0 0 1] -- Used by lamp 3
Signal 2: [0 1 0] -- Used by lamp 6
Signal 3: [0 1 1] -- Used by lamps 2 and 5
Signal 4: [1 1 0] -- Used by lamps 1 and 7
Signal 5: [1 1 1] -- Used by lamps 0, 4 and 8
Now to encode the signals into an alphabet. In order to avoid signals interfering with each other, we'll multiply each of the 5 signals by 10 (We could have multiplied them by 3, the number of characters to display, but for us humans used to work on base 10, it's easier to visualize when multiplied by 10, it just mean we are wasting some numbers), and we'll assign those "pure" signals to each of the lamps.

So when you build the 3x3 lamp array, you put on each lamp a condition of "Anything = signal_number", where "signal_number" is:

Code: Select all

50 40 30
10 50 30
20 40 50
As you can see, each lamp has the signal that we found it uses, multiplied by 10.

Now to create the alphabet of signals to put into the constant combinator. What we do here if for every one of our 5 signals, add to it the index of the character when the signal needs to be on. For example, signal 1 is [0 0 1], which means it only needs to be on when displaying the third character (index 2, since indexes start at 0), so we multiply the signal by 10 (again, to prevent overlapping) and add 2 to it, resulting in 12. Repeating this for all the characters in all the signals, we get:

Code: Select all

For signal 1: 12
For signal 2: 21
For signal 3: 31 and 32
For signal 4: 40 and 41
For signal 5: 50, 51 and 52
Some notes here, if a signal is never turned on (meaning it's [0 0 0 ... 0]) then it will not generate any alphabet entries at all. On the other hand, if a signal is always turned on (like the [1 1 1] signal 5 in this example) it will generate an alphabet entry for every character, this is why we must multiply the "pure" signals by at least the number of characters to avoid overlapping.

Now, since each alphabet entry is already separated by their "pure" signals, we can just mix them and send them together (by constant combinators, for example), with the certainty they will not activate any lamp unless the index of the character they belong to is subtracted from them (this is why we added the index earlier).

So in a constant combinator we need to add signals with the following numbers:

Code: Select all

12, 21, 31, 32, 40, 41, 50, 51 and 52
And finally, just before those signals enter the lamps, we must subtract form all at the same time the index of the character we want to display, an arithmetic combinator with the instruction "Each - signal_with_index => return Each" will do just that.

Here's the output from the script I wrote to automate all this for some digit characters samples:

Code: Select all

$ ./font_dictionary.py -d digits_smallest

  #     #       # #     # # #   #   #     # #   #       # # #     # #   # # #   
#   #     #       #       # #   # # #     #     # # #       #   # # #   # # #   
  #       #       # #   # # #       #   # #     # # #       #   # #         #   


Configuration for the display:
40 80 20 
60 50 70 
10 90 30 

Number of signals: 57
Configuration for signals:
13 15 16 18 23 24 25 27 28 29 32 33 34 36 37 
39 41 42 43 44 46 47 49 51 52 53 54 55 56 58 
59 60 64 66 68 69 70 73 74 76 77 78 79 80 82 
83 85 87 88 89 90 91 92 93 95 96 98
And here's the blueprint of the display I created with those:
3x3 digits
And another example with a bigger display:

Code: Select all

$ ./font_dictionary.py -d eight_bit_slim

Hi all,

Does anyone have a blueprint saved off for XKnight's 5 digit display? I'd love to use it, but it relies on curved railroads which are now removed so I cannot import it. I'm hoping to use for it for a minimalist 3 digit display.

Thanks!
