DJjondent vids using NLC & Serge
Jono has posted some great vids using nonlinearcircuits panel with his Serge panels, usually focusing on a single module each time.

board order
sent this off tonight.
note the power distro boards with space for Euro connectors.......Dan!
Also has more Korg 800dv ext input PCBs, dual VCA/panners, Envelope followers/LFOs and Vox filters/LFOs. I like LFOs.

vocal filter
This board contains 4 LFOs, with individual and summed outputs. Plus a set of four parallel fixed and variable bandpass filters with VC Q and a VC notch filter to form a vocal effects animator. This was inpired by the Vocal Effects Waveform Animator in Electronotes, but has been changed to give more functions, use available smd ICs and to make it ridiculously complex. Each of the variable filters has an individual output, the filters are also summed and passed thru a notch filter to get the vocal effects.
The summed LFO outputs are all different, each draws the outputs of three of the four LFOs, so summed outs consist of signals from LFOs 123, 234, 341 & 124.
There is a spare OTA stage which I may implement as a VCA, but not sure if I can be bothered at this point. This design has taken nearly 3 months to complete.
It will take up 6 columns on a NLC panel, thankfully no wiring to do.

Neuron / Difference Rectifier PCBs
AU$8 each (+ shipping AU$5 per order)
From thread on muffwiggler:
I keep getting asked about these so have sent off a design for a pcb containing 1 of each of these circuits.
The Difference Rectifier has 4 inputs (two + & two -) and two outputs. The Neuron has two inputs and one output. There is a pad labelled 'ext' where extra inputs can be added if desired (use a 100k resistor attached to the jack).
All inputs for both circuits can be wired to attenuating pots if required. The two pots on the PCB are the critical Offset and Invert controls for the Neuron. The Offset is slightly modded from the previous Double Neuron PCB as it now ranges between +V and -V and its effect is halved by the 200k resistor to give greater useful range.
Schematics and demos - Difference Rectifier and Neuron
Build manual pdf
The PCB is small so will suit Euro builders. Approx 1.5 by 2 inches.
The 2 board mounted pots (both 100k) are 1 inch apart, the idea is to mount the PCB to the panel with threaded pots. There are 2 mounting holes otherwise if you want to attach the board some other way.

new chaos circuit
Playing around with a new type of chaos circuit. It is an extension of the Muthuswamy/Chua 3 component chaos circuit (which has just an inductor, capacitor and a memristor). In this one I developed a circuit to mimic a complex memristive system. Whether it makes it into a synth module or not is uncertain, it needs five AD633s at $8 each. For now it is just some good pictures.
update from post on 28/4/2012:
A utility PCB, no pots, just jacks. Moog fixed filters - brass, vibes, humana, funk, harpsichord another fixed parallel BP voice filter (called gargle).
These can of course be used with any audio or noise source but are intended primarily as filters for the extra outputs on the Veena.
Also has white noise, pink noise, random vibrato, slow random, chunder (roar), two difference rectifiers and a 4046 phase locked loop circuit.
Somewhat pleased to find everything worked very nicely. I tweaked a couple of resistor values to get the white noise level off the rails and get the LED brighter and flashing more often. Otherwise it is fine.
One nice feature is to daisy chain the filters to get new sounds.
The 4046 PLL was a bit of a gamble but it sounds great, adds a bit of distortion and spits, screams and fizzes as it tries to track the incoming signal. I built the proto-type with nearly all ceramic caps, figuring that will be the worst it can sound, but it actually sounds good. the original Moog passive filters, that these are based on, were likely built with ceramics anyway.

Filter Panel
This one has
"it's 555..." resonator/drone/noise source with CV control of pulse width for all five stages (plus a CV all input)
"Bleeding Gates" VC Slew: double module each has three individual channels giving 6 in all.
"Double Jerkoff" two chaos generators based on Sprott's jerk circuit. Each has X, Y & Z outputs and inputs. the input signal can be used to get the outputs to sync (when it feels like it) with everything else
"Spam filter" transistor ladder VCF
VCF - filter based on Arp and Electronotes designs.
"Divine CMOS" sub-oscillator, harmonic divider/mixer, harmonic ring-modulator, pattern generator, sequencer....
The user manual can be found HERE
