Build server application

[Lasagnenator]

Minecraft name:My Minecraft name is Lasagnenator.
What do you like the most about redstone?:Redstone gives you many possibilities to explore electronics.
What's a thing you have made which demonstrates redstone knowledge?:I have built a 4-bit subtractor/adder which can switch between adding and subtracting.
What does it do?:The device uses XOR gates to determine what the output is. Then it uses an AND gate to see if there is a carry or not. For the subtraction part it invertes Input B and add a carry in.
Image and/or video, from imgur.com or youtube.com:The image of the Adder/Subtractor is http://imgur.com/tdU1kWF
Do you agree with the rules?:I agree with the rules of the server.

Hi, unfortunately this doesn't meet the requirements of a build server application. At the very least you need to be able to build an Arithmetic Logic Unit. This can be relatively easily acheived with what you have right now, as an ALU can be made just from running extra control lines into your adder/subtractor. I'll leave it up to you to figure out how to make one (may take some time to research), or you could apply for the school server and learn about ALUs there :3
