No marble out if there is one marble in.
Marble logic gate.
This is an amazing brain teaser because when there are more marbles on the board the riddle becomes harder.
I decided to make the or gate after the not gate because with these two you can make nand and and nor gates.
Logic gates are an abstract device which can be implemented with electromagnetic relays vacuum tubes or transistors.
The key mechanism in the or gate is the rotation of one of the cross beams.
So what do a and gate does.
No marble out if there is two marble in.
The first gate we did was the and gate.
If there is no marble in.
The purpose of the logic game is to make all marbles disappear and leave only one marble.
These implemenations have been successful in computing in part because of various properties of chainability durability and size beyond their basic binary stability.
The or gate was the first logic gate i designed that actually does something.
