DelayNoMore 3

This module contains three PT2399 delay chips that feed into each other to create a loop.
The delay time for each stage is individually CV controlled and each stage has feedback controls to itself and the previous stage.

Each delay stage can be isolated and used on its own so the module can be used as a triple delay or a 3 stage delay.....kind of:
If you are familiar with the original DelayNoMore, you will know it is a crap delay but an excellent noise module, this one is designed to be much the same. The big differences being 3 delay stages instead of 2, CV control over all 3 stages instead of 1 and, as mentioned, the stages can be used individually.

To use, the input signal(s) can be patched into the 1-3 inputs and the three outputs can ll be used to get different signals. The 2nd row of inputs use the jack switches to forward the output of each stage to the input of the next, so if you wish to use the delays individually, use these inputs to break the loop.

There are pads on the PCB to place resistors in parallel with the LDRs in the vactrols, this is to tame the delay times somewhat. It is up to the builder to decide how lame or how out of control they want this module to be.

4HP MIX

The simplest module in the NLC range, a 4 input mixer. It has just 14 components to solder onto the PCB, so a very gentle intro to surface mount soldering.

The pots are 0 at centre, -1x gain to the left (inverts) and 1x gain to the right.

Pot 4 will act as a voltage offset if nothing is patched into input 4. It can supply -5V to +5V of offset. If you do not want any offset, leave pot 4 at midpoint, or patch your signal into input 4.

The module will work with audio and CV signals. It is useful for creating sequences from logic modules such as the Divide&Conquer, BOOLs or 1/n.

Bi-di Choppers

This is a dual stripped version of the original Chopper. A very easy build with few components. It can be used as a 1 into 2 switch or 2 into 1. A CV signal can be used to help control the switching point, tho Choppers are different from regular switches as the signals being switched also control the switching.
It can be used to process CV and audio signals.
The basic idea for the Chopper is from a 1975 paper titled – ‘A nonlinear modulator using delta principles’ by S.K. Mullick and K.R Srivathsan, although this version drops the comparator output, makes the slew stage adjustable, converts the 2 inputs so they can also be outputs and adds an in/out stage before the slew section.

1/n

This module is straight out of the Lunetta playbook. It is simply a CMOS 4018 with buffers on all of its inputs and outputs, along with a 4081 to enable further divisions.
The divide by is patch-programmable, simply patch whichever number you wish to divide by back into the input and feed it a clock. The other outputs will follow the 1/n at various phase differences depending upon what is going on.
You can get quite silly by feeding signals into the J1-J5 inputs (jam) and sending a high signal (anything over 1V) to the preset enable.

I can't believe it's not a VCO

PCB set = USD20
panel = USD20
assembled = USD180

This module is based on ideas presented in Electronotes #132. It is a VCF with a 'filter exciter' section to allow a wide variety of acoustic, semi-acoustic and not-acoustic-at-all sounds. In a sense it takes the concept of pinging the LPG or ringing a VCF one step (or 2) further. The decaying sound is fed back into the input via a VCA. The VCA can be controlled by a gate or an envelope (or both).
Another interesting point is higher frequency sounds tend to be louder.....which is what happens naturally in the big room.

Signum Hyperchaos

This is an expansion of Primal Hyperchaos, based on the description in a paper by C Li, et al. The internal signum switch has been brought out to the panel. It can be used as a stand-alone switch (don’t expect it to be clean and nice) or it can be used to inject signals into the hyperchaos circuit or control the switching of the hyperchaos. Some actions will make the oscillations stop; others will make them go nuts; experiment! 

It can be built to run at different speeds simply by installing different capacitors. Very easy build, no special components needed.
There are 5 different CV outputs and 1 gate output. The CV IN is associated with the CLIMAX pot which determines how high the peaks go. The module can be greatly influenced by the CV in signal and can exhibit some fairly nutty responses at times. 

IN1 and IN2 are the inputs for the Signum switch, they are also connected via their switching pins to the internal workings of the hyperchaos circuit. SW2 is also the internal switch for the hyperchaos circuit so if you use this input you will find that switching only occurs with an external signal. Use SW1 if you want to control the switching of the hyperchaos with an external signal.

As ‘signum’ implies, the switching signal is +1 or -1. This means you need a signal crossing 0 to make switching occur. A regular gate may or may not work, depending whatever else is going on at the time. The signum output is also the W output, as indicated on the panel.

GENiE - GEneralized Nonlinear Extrapolator

GEneralized Nonlinear Extrapolator 

This module is made of 3 neuron circuits and a difference rectifier. The neuron outputs are fed to the switching pins of the next neuron’s attenuated input; 1>2, 2>3, 3>1. This means the circuit will work with a single input signal, delivering all kinds of mayhem at the outputs. 

There are also 4 shared inputs so that the same signals can be fed to neurons 1&2 and neurons 2&3. The Difference Rectifier compares the outputs of neurons 1&3 to the output of neuron 2. If you want to use the neurons individually then turn down the input pots or use the upper neuron specific inputs to disconnect the signals coming from its neighbour. 

Just like a set of synaptically connected neurons, this module is noisy and unruly. It is never going to learn anything it lives in and for the moment. It can be used to process audio, CV or audio and CV……do whatever you like to it. 

The name is from the computer described in the 1964 Keith Laumer novel – The Great Time Machine Hoax, although this module differs in ability (can’t time travel or get married ….. afaik), the name is quite suitable.

SPASM - LDR controlled jerk chaos


This module takes the classic Sprott jerk circuit and replaces all the resistors with LDRs.....a 7 way vactrol. This means the brightness of the LED in the giant vactrol controls the frequency of the circuit.
It is a very easy build and will give you a very flexible chaotic circuit. The CV inject jack allows you to control the chaos with gates and CV, some signals will cause it to pause or stall, others will make it glitch & freak out. CV freq controls the LED which, in turn, controls the resistance in the LDRs.
It is a very flexible build; you can use any LDRs you like, so long as they are the same. You can also use any capacitors you like for CAP, so long as they are the same.
Of course, the LDRs and capacitors you choose will affect the behaviour & frequency range of the circuit. GL5516 LDRs go to 500kΩ off resistance whereas GL5549 go to 10MΩ+ (anywhere from 10MΩ to 20MΩ), so will be a lot slower but will give a much wider frequency range and some very unpredictable outputs. Similarly with capacitors 10uF will be a lot slower than 10nF.
If going for the more extremely slow values, GL5549 LDRs and 10uF caps, the module will stall at minimum pot settings and generally needs a CV on the CV freq input to make it operate. This is actually a good thing as you can turn the signals on and off with CV or gates.

(bad) Digital Filter Simulator

This module is based on ideas presented in a 1969 IEEE paper titled - Hybrid Implementation for Sampled-data controllers. The paper presents the canonical form of a generalised digital filter made using analogue elements.....yes this is an analogue circuit; all CMOS and op amps. I played around with various versions for a few years and, as usual, settled on the simplest and cheapest version.

Incoming audio signals (or CV if you want to use it as a pattern generator) are fed to a 4 bit A/D stage, these 4 bits then go thru a 4 stage delay (shift registers). Each delayed bit is re-united with its siblings via four D/A stages and the stepped signals are then fed back to the input via an attenuator/inverter stage and are fed to the summed output, again via an attenuator/inverter stage.

The circuit is controlled by the clock input that ticks over the shift registers. CV controlling the VCO that supplies the clock signal will in turn control the filter. The Range pot needs to be set to a suitable level, I like it when the peak LED is flickering. Range can also be controlled by CV which will allow you to shift from a 1 bit signal to a 4 bit or overdrive the crap out of it and lock everything up. It is interesting to supply clock signals that are multiples or divisions of the audio signal, but like all NLC modules, feel free to do whatever you like. As mentioned, supplied with a gate and a CV it will perform as a complex pattern generator as well.

I will get a demo up soon, but will promise this doesn't sound like a filter......it is very noisy and splatty.
