In 2015, our IT teacher asked us to work on a project of our choice for a couple of weeks. As we previously learned about circuitry and I really was into Minecraft at that time, I decided to create a calculator in the sandbox game.In Minecraft it's possible to create circuits by placing virtual wires and very basic electronic components.First, I designed a 4 Bit calculator in a circuit simulator and recreated it in Minecraft. I kept expanding the circuit and added a BIN2DEC/DEC2BIN converter, a 7-segment display and an incrementor/counter. I also created an interactive in-game tutorial for my teacher, so he could try the calculator himself.At the time I submitted the project, it had grown much larger than I ever expected it to become. I was quite proud of myself and the teacher liked it as well.
