so i made this now to keep Track of how much i have. so that i know when i'm short of a Pack kind.

i used 9 Lamps and made sure that every Science Pack can only Stock up to 3k. so when all 9 Lamps are on from one Bar, i know that i have 3k packs.
3k is not the best to Divide by 3... but it worked and the Bar Increases at a Semi-Balanced Rate.
also used Arithmetic Combinators to Turn a Science Pack Signal into a Color Signal to it's Respective Color. (Red Science Pack -> Red Signal, etc.)
Simple, but works.
