DIV2: Power-of-two clock divider (4HP)

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.

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