Binary Adding Machine

Description

This is a 3D printable 1/2 scale version of the wooden binary adding machine by Matthias Wandel: http://www.sentex.net/~mwandel/

See a short demo of the 3D printed version here: First time glitched on "32", but second time worked as it usually does: http://youtu.be/GhgaMkGWSNI I may make a better video showing how it adds up a series of numbers, up to 63. The machine resets or wraps around 64.

Educational device to see the binary system in action. Watch as binary bits and bytes toggle in physical form. The steel balls will register the sum of all the values being added together.
