The final circuit consists of two subcircuits ... and comparison are implemented. The logic is based on the relationships P = Q+1, P = Q-1, P = Q+2, and P = Q-2. By combining inputs of Q using OR ...

The details are pretty involved, but in simple terms the construction features logic gates built in the game's city grid spaces ... functioning circuit – a simple computer.

The idea behind this project is to have a marble simulate current in a circuit, with the walls, pipes and planks acting as wires. Using some collision logic, I plan to add working logic gates (AND, OR ...

and Bill Gates’ Android phone. Android Circuit is here to remind you of a few of the many things that have happened around Android in the last week (and you can find the weekly Apple news digest ...
