Hello people... I have been a no-life and created a massive 4-bit adder in MineCraft.
(Q: What is 4-bit adder?
A: It sums two 4-bits binaries to each other. for example 0001 + 0010 = 0011)
And that's not all. I also made 7-segment hexadecimal display and a converter what converts the binary to the segments of the display.

^ This is the adder. The 4 levers at the left are input 1, and the 4 levers at the right are input 2.
See that at the moment they are set to 0100 and 0011, as lever on = 1 and lever off = 0.

^ This is the 7-segment display. Note that it has 7 segments. At the moment it shows "7" which is 0111 in decimals, which is answer to 0100 + 0011.

^ This is the decoder converter typed thingy system wutever. It tests what is the answer, ranging from 0 to 15. At the right side you can see the 7 "OR gates" which lit the right segments.
Thank you for reading =P
