Nonlinearcircuits (NLC)

  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...

This module is inspired by an article from Harald Bode discussing ring modulators and multipliers. I can’t seem to find it atm but pretty sure it was AES, anyway it was one of those things that...

This module is a 22HP 10 channel vocoder based on the Syntovox 222. I own a 222 and have always been impressed with the sound and elegant design, so it was an easy choice of where to start. The...

Seven attenuators in an 8hp Eurorack module. Nothing too fancy.     On Demand Info These kits and assembled modules are offered on demand, click the link to learn more.

This module is an updated version of the 4U CMOSC (CMOS drone Oscillator). It consists of 6 oscillators; each can be switched between two frequencies set by a single pot. When the pot is in the...

The idea for this module came from a schematic that has been floating around the web for years - 'beat frequency indicator' This version drops the CV, pots and XNOR output of the original ‘Beat...

This module is based on four Signum circuits but converts them to process 4 signals rather than two, extracting positive and negative aspects of the incoming signals and re-attaching them to each...

This module is a simple 4 channel preset drum module with a distortion circuit added on the summed output. The distortion circuit can be used separately. The drums are based on the so called...

This module is loosely based on the Karplus Strong algorithm. You may get it to make some plucked string sounds or you might just get lost in a rubbery glitch mess. Most likely, Messrs. Karplus and...

This module is based on an article presented by E. Muller (Jan 1983 Elektor link to archive.org) in the “Ejektor” section, meaning it is an imperfect but interesting idea (my italics). Of...

In Australia, there is an entrepreneur called Dick Smith who ran a chain of electronic hobby stores in the 70s and 80s (now he makes breakfast cereal). He used to publish circuit books every year...

Working on the CellF project brought two members of our group into contact with Alvin Lucier. Originally, we planned to take CellF to NYC and hook the neurons directly to Alvin. Then covid happened,...

  NLC1135 Snake Joke (Black NLC) The core of this module, where the logic and processing happens, was designed by Tom Hirst. Tom has been using the design for a few years in his 4U system and...

This is a chaos module based on the Mackey-Glass equations which were developed to show the delay in physiological systems when producing or reducing certain cells in response to variations in...

  NLC1138 Razors (White NLC) This is a dual voltage controlled version of Razor on the Tinkle module. I have always enjoyed the Razor, especially when used with fast drum patterns, so it...

This module is a 4HP three input/eight output version of Let’s Splosh. The inputs are combined in different ways via difference rectifier circuits. These circuits take the difference between...

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...
