Description

Xorand is a four-input logic gate module designed for live manipulation of up to four separate image or pattern sources via front panel performance control switches.

While it may be a little bit tricky to describe what Xorand does, it is actually very easy and rewarding to use – just plug in some image or pattern signal inputs and start toggling the switches to tweak and adjust the output to your heart’s content 🙂

Xorand works by first converting each of Xorand’s four inputs into a digital (fully on or off) signal, then combined it together with each of the other inputs in one of three ways.  An input set to AND mode acts as a filter, only allowing other signals to show through where it is “lit” (+0.5V or greater).  Inputs in XOR/OR mode are either layered over each other like overhead transparencies (OR mode) or combined so that an even number of input images that are both “lit” at the same spot cancel each other and result in an “unlit” pixel (XOR mode).  XOR mode is particularly useful for producing complex, interrelated patterns that are directly related to the inputs, but that brings balance and “negative space” to otherwise simple visual compositions.

Xorand comes as an unpopulated PCB/panel set for DIY, which means you get the satisfaction and enjoyment of learning to build it yourself.  The Xorand Manual V0.1a provides all the information you need, including a shopping list for the electronic components required.
