1U Sloth Chaos

These are Sloth chaos modules available in 1U 6HP panels.

The panels are available in Pulp and Intellijel formats, please specify when ordering.
Please note, the PCBs only have eurorack 10 pin power connectors, not the Pulp Logic 3 pin type.

They are available in 3 variations, the same as on the triple Sloth panel; Torpor (15-20 second orbits), Apathy (1-3 minute orbits) and Inertia (15-20 minute orbits). The same PCB is used for all 3 variations.

Each has 2 outputs which supply different signals drawn from different stages of the circuit. The input can be used to inject a signal into the circuit, some signals will have no effect, others will cause periodicity at different stages, others will alter the chaotic orbits. I find very slow sine signals, from the Feague, are very good. Of course you do not have to input any signal, the sloths will happily meander along without any help.

Dispersion Delay

This module is based on ideas suggested by Lucas Abela.

It is three vactrol based bandpass filters in parallel, each filter is fed into a voltage controlled delay stage. The outputs are available individually or there is an OUT ALL where all 3 signals are mixed.

Me being me designed the delays to go into stutter/zipper/breakdown territory to create the usual noise I love. If desired the delays can be built to remain in their normal operating regions.

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.
