Nonlinearcircuits (NLC)

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...

  NLC1087 Dual LPG This is a pretty standard lo-pass gate, except it uses the black box vactrol method seen in the Shat-noir Phaser and Noiro-ze VCF/VCA. DG analogue switches are used for...

  NLC1088 Mogue Mixer/VCA   MOGUE is a VCA and Mixer inspired by early Moog designs, with some mods to get them into ‘Eurorack standards’ (!). Both circuits can be overdriven to...

A simple and super useful mixer and line level output with added headphone monitor.  Inputs 3xMixer in : Signals in to mix  Phones in : Audio to monitor on...

  The NLC Dispersion Delay is three vactrol based bandpass filters in parallel, with each filter feeding into a voltage controlled delay stage. The outputs are available individually or...

The NLC Mobius PiLL is a chaotic noise module. There are several papers describing ways to couple PLL (phase locked loop) ICs to create chaos. I have been sitting on a stack of them...

  NLC1092 Delay No More 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...

Full kit to build the andrew f neron/difference rectifier module in euro; Includes the pcb,magpie modular white 16hp euro panel, pcb and panel parts, power cable etc.  This is a great module for...

  NLC1096 Neuron Diff Rectifier (White Magpie Version)   Full kit to build the Andrew F Neuron/Difference Rectifier module in Eurorack. Includes the PCB, Magpie Modular white 8hp...

  NLC1099 BBX 291 VCF   This module is based on the Buchla 291 vari-bandwidth bandpass filter, tho it uses the blackbox rather than vactrols. The CV sections have been changed from the...

Nonlinear Circuits Clump The NLC Clump is a 4x4 CV controlled matrix mixer (MM). This means there are 16 VCAs on-board along with 4 mixers. It can be used as a regular mixer if you prefer. The...

This is another somewhat lazy design, but a nice easy build.. Basically grabbed the NLC Triad and replaced the pots for Attack & Decay with vactrols Not sure why it hasn’t been done before,...

This module is a dual sample & hold with voltage controlled slew for each channel. It contains a simple jerk chaos circuit running at approx. 300Hz to supply a signal for sampling. So, it is...

This module was designed based upon suggestions from Alex Brunori. The idea is to play a video (or skype or whatever is the newest thing) fullscreen on your phone and place the phone on the LDR array...

  NLC1107 Bongo Fury   A triple version of the Bong0, one of those simple modules that pumps out way more character than it should. The sections can be controlled by signals on trigger or...

  NLC1108 Stooges This module contains three individual jerk chaos circuits. They can be built to run at different frequencies and are quite responsive to incoming gates and CVs, not necessarily...

  NLC1112 Frolic Sequencer   This module is an 8 stage sequencer/sequential switch. The stages can be controlled by CV or by gates and triggers or both. Feel free to run it audio rates and...

  NLC1113 Intimacy EQ+Drive This module is based on the Intersound IVP Pre-amp. It is not a clone as the inputs and outputs are changed to suit Eurorack voltages, nevertheless the core sections...

  NLC1114 Suppository Phaser   This module is supposed to be a phase shifter, but is so badly designed that it spits, sh!ts and burps all over the place. It can even do it without even...

  NLC1115 Valmorification EG This module is a slope/envelope/function generator. The core is based on that seen in the Serge Slope Generator, Korg PS3100 EG, Maths, Rampage and a dozen other...

This 4HP module is a thru 0 VCO using the SSI2130 chip. It is designed as an FM operator as per the concepts delivered by John Chowning, so for best results 2 or more are needed (get 6!), along with...

This module is a 24 stage phase shifter using LDRs in a black box. It is a little more complex to build than usual but most of the build is repetitious and not so difficult. I have added plenty of...

This module started out as an attempt to develop yet another chaos circuit by linking different nonlinear sub-circuits in series, from Chaotic Oscillator Based on Delay Line - Milan Stork. Then...

This module grew from one of those throwaway circuits in a 70s electronics magazine for a 2 input passive analogue XOR. Of course it is great and production of CMOS XOR 4030 and 4070 chips was...
