Logic gates are an abstract device which can be implemented with electromagnetic relays vacuum tubes or transistors.
Marble logic gate.
These implemenations have been successful in computing in part because of various properties of chainability durability and size beyond their basic binary stability.
The purpose of the logic game is to make all marbles disappear and leave only one marble.
The game has 45 boards all arranged differently so you move from easier boards to more harder boards.
I decided to make the or gate after the not gate because with these two you can make nand and and nor gates.
The or gate was the first logic gate i designed that actually does something.
The first gate we did was the and gate.
This is an amazing brain teaser because when there are more marbles on the board the riddle becomes harder.
When we were reflecting on how to make the logic gates we needed we always started by stating what the gate is doing in common term.
No marble out if there is one marble in.
The key mechanism in the or gate is the rotation of one of the cross beams.
No marble out if there is two marble in.
