Item Counter and digital display (each piece is separate)
-
Item Counter:
Connect Input (any signal) with a GREEN wire to the top left Decider, diagonal from the Constant Combinator.
Take output (signal 'N') from the right side (opposite the Constant Combinator) with a RED wire.
Counts items per second by default, but it's easy to change the time by editing the Decider next to the Constant Combinator. (Default is 60 ticks = 1 second)
Set it to 514 (60×60÷7) for example to count SPM with 7 science belts connected.
-
Digital Display
Connect input as signal 'N' with a RED wire to the bottom right Arithmetic Combinators (or the power poles)
If you want more digits, simply copy the left two digits and repeat towards the left.
All digits are identical except the 'ones' digit where the combinator storing the font is located instead of a zero-blanking decider.
Only has numbers, use a different blueprint if you want letters.
