I thought long and hard about how to make a clock divider sound cool.

I gave up.

This is the successor to my original divider module (and it's short-lived 1U counterpart) but is slightly different in that it now has divisions down to /64 - that's it. For best results, use a trigger voltage of around 5-6V (more is better, within reason) although anything above around 3V will work. At audio frequencies you could even use it as a sub-octave generator, and feeding individual outputs into a R2R DAC can yield some interesting sounds.

Whilst this is outwardly identical to its predecessor, the underlying circuit has changed a little - instead of using discrete transistors, it now uses Schmitt triggers to clean up any input signals and, perhaps more importantly, invert the clock signal so that the divider will trigger on a rising edge, rather than a falling one. This means no more messing around with attenuators and whatnot.

Functionally, though, nothing has changed - it still divides clocks.

100% hand-made with surface-mount components, the panels are fabricated from 1.6mm FR4 (PCB material). Mounting hardware and a power cable are also supplied.


CURRENT CONSUMPTION: 50mA max (+12V), 0mA (-12V) - higher clocking rates will increase power usage

WHAT DOES IT DO? Given an input (typically a square wave) with a given frequency, this module will generate a range of square waves whose frequencies are a number of octaves lower than the input frequency. The 'power of two' part comes from the fact that the IC on board outputs frequency division of 2, 4, 8 etc.
If you think more in terms of beats-per-minute, then consider an input clock at 256bpm - the "/2" output will output a 128bpm square wave, "/4" will output a 64bpm square wave and so on down to 4bpm(!) at /64.
Alternatively, in terms of frequency: given an input with a frequency of 440Hz (concert A), the "/2" output will be at 220Hz (-1 octave), "/4" will be at 110Hz (-2 octaves) and so on down to ~5.5Hz (-6 octaves).
In either case, this functionality is useful if you wish to drive a number of modules at different tempos from a 'master' clock. The module also works at audio rates, and feeding the various outputs into an resistor DAC or similar can yield some interesting results.
