Combinator based power detector

[Tistel]

As desider and arithmetic combinators need power to work.
You can use them to detect if there is power in a electric network.

Here is a simple example circuit.
It lights up a different lamp depending on if the left electric network has power.

It it split in two electric network and it measure the left one ( it expect the right one to always have enough power )
It will use two lamps to show the power status.
If there is power the lower light is on, if no power the upper light is on, when there is some power but not enough the light flicker back and forth.

How it is build
left:

• green + 1 -> green
  green < 100 -> green ( input count )

right

• green + 0 -> red
  red + 0 -> red
  green = red -> 1 yellow

How it work.
The left part loops the green signal from 0 to 100 over and over again.
( when the power drops it will count slower and stop when the power is out )

The right part check if the left part count fast by comparing the current green value with a slightly older value ( changed to red and delayed by the two arithmetic combinators )
