Full Adder Circuit in Minecraft Redstone

Conor built this today, first creating a Half-Adder circuit and using structure blocks to copy and paste into the required Full-Adder layout. He then tested that the various combination of inputs gave the outputs specified in the truth table. The next build is to chain a number of these circuits to create a Ripple Carry Adder, but before that he has to create a smaller, vertical version of the circuit. He didn't want to copy a design from the web, he wanted to have a go figuring out himself. Designing logic circuits at age 10!

Conor and Dad had a rare game of Battleship in the afternoon. Almost used up all the white pegs.
