Basic Item counters, compatible with most mods, uses Display Panels and Arithmetic Combinators to create counters that display the object being counted, as well as the count up to 999,999 of each item.
Included in the book is single item counters up to 5 item counters, plus extensions for those who want even more. Connect input to the to the Green Input of Combinator on the top row, Left end. there is also a Temperature Probe version which uses less screens since it only needs to display up to 1,000. I will continue to work on the details of these.
If you are wanting to use the extensions, just connect each Display Panel to the Combinator directly above it with a Green Line.
