Complete LZX Castle series manual (DIY kit version)

Castle is based around 3-bit binary digital signals:

Imagine 3-bit binary like an 8 layer cake. All combinations of 3 bits create 8 possible values. Ever seen NTSC color bars? If you send 3-bit binary into RGB, you get those colors.
All the inputs on the modules are comparators, so they can perform a 1-bit conversion of an analog signal:

The ADC module slices analog voltages up into 3-bit binary numbers:

If you patch a triangle waveform into the ADC, you get a step pyramid waveform out!
The DAC module converts 3-bit binary numbers into analog voltages:

There’s also a voltage controlled oscillator, these make horizontal or vertical bars in different sizes:

You combine the binary outputs to make complex patterns with these:

It gets freakin crazy when you start messing with the counter, shift registers, and flip flops, which allow you to program memory states and reveal the true digital nature of everything:

It follows LZX standards, for patching and interfacing video signals, and requires Cadet 1+Cadet 2 or Visual Cortex as core modules:…/842
