Binary Counter - a K'nex Ball Machine Path Separator

About: I like to build with K'nex and Lego.

Programmers' joke:

There are 10 kinds of people in the world: Those who understand binary, and those who do not.

Get it?

10 is the number 2 in binary.

Here are the instructions for the new path separator from my ball machine Grid Tower II. The binary counter is my most complicated path separator. It separates balls while at the same time counting in binary. You can add as many bits (binary digits) as you want. Below is the parts list for a 3-bit counter:
