Even if you know it, the fact that computation can be achieved in an amazing range of different ways still comes as a surprise. Programmer lapinozz decided to prove the point by building a full adder ...

An elementary electronic circuit in the arithmetic logic unit (ALU) of every CPU. The half-adder does nothing more than add one bit to another. GPUs have millions of half-adder equivalents. The output ...

We worked our way up to logic gate implementations for half adders and full adders, as illustrated below. In closing, I asked you to start thinking about how we could use these functions to add two ...

Hi, first post here, this place has really come in handy a few times. Anyway, heres my question: I want to connect two 4 bit adders together (school related) in order to make it an 8 bit adder. Here's ...

Computers built using discrete logic chips? Seen it. Computers from individual transistors? Impressive, but it’s been done. A computer built out of electromechanical relays? Bring on the ozone! The ...

Most of us can do simple math in our heads, but some people just can’t seem to add two numbers between 0 and 3 without using paper, like [Aliaksei Zholner] does with his fluidic adder circuit built ...
