fk1t VCF

1st play with the prototype.......which worked beautifully!
This has a core based on the Korg FK-1 pedal, which is a similar VCF to the ones found in the 800dv, 770 and 700 synthesizers. These VCFs have low pass and high pass stages in series. The main difference is this version uses vactrols as the variable resistors.

the giant B0N0

Basically I mated a vactrol PiLL with the DelayNoMore, so it has a PLL chip, a delay chip & 2 vactrols. Pretty much does whatever it wants most of the time.

Chopper & Mixer panels back in stock

more white & gold!

1050 MixSeq

This module is based on the Arp 1050 mix sequencer. Although this version drops the VCO and push button functions. Using the switches, it is an 8 step sequencer, two 4 step sequencers, an 8 input mixer, 8 stage sequential switch, two 4 stage sequential switches and there is also a difference rectifier giving the +ve and -ve difference between stages 1-4 and 5-8.

The assembled PCB shown was a proto-type but the sockets should all be on the same side and the LEDs are actually thru-hole. I just used smd LEDs as they are easy to remove.
It is pretty much all SOIC and 0805 components, but a pretty easy build.
PCB - US$22, 16HP panel  US$30, assembled - US$220

Open Source Eurorack cases

Local case builder and cellF designer Nathan has posted up all the files for his eurorack case designs. Feel free to choose one, send it to a lasercutter service or, better, take the file to your local hackerspace and get a new case with $5 worth of wood.
See the thread on Muffs for info on where to get these made and any other tips

Modular Addict

A new store for DIYers has opened in the USA - Modular Addict. They will stock a selection of NLC PCBs (and other designers too). They will have their own panel designs to suit the PCBs. Eventually they will also have components kits available.
Of course you can still purchase directly from me as well, it is nice to have options!

New in 2016

 From Arp2500, this is based on the 1006 Filtamp, minus the amp.....it is squirty
 The Giant Bono - a delay chip & a PLL with 2 vactrols.........just crap!
based on the ARP 1050 Mix-Sequencer, minus the switches and VCO. It is a standard 8 stage sequencer, or two four stage sequencers, or an 8 stage sequential switch, or two 4 stage sequential switches (good for routing audio and/or CV), or an 8 input mixer, or two 4 input mixers (with an 8 input output anyway) and there is a difference rectifier in there giving the positive and negative results of the difference between stages (1-4) and stages (5-8).
Also the LEDs spin around in a circle giving a nice light show.
16HP, no wiring, all smd.
There's actually not that many parts, the logic chips do all the work

Phaser/Flanger based on the Aries 329. It has 11 matched NPN pairs and a set of matched FETs. It is actually quite simple to match FETs, a circuit will be given in the build guide. Pretty much all surface mount.

FK1t VCF - inspired by the Korg FK-1 pedal. It has a similar topology to the early Korg filters found in the 700 and 800dv synths but uses vactrols. What could go wrong?

Pomona cable holder

Skye of Terminal Sound System very kindly sent me a cable holder and a link to listen to some of his music.
as you can see I am very pleased with the cable holder:

 From this:
To this!

I have TSS's album, A Sun Spinning Backwards, blasting away in the shed. Totally lush and trippy, do yourself a favour!

TRIAD - triple envelope generator

PCB - US$18
panel - US$20

These are AR or AD generators that will fire on a trigger or a gate, giving envelopes up to approx 25 seconds. A single gate to input 1 will fire all 3 envelopes, when nothing is plugged into inputs 2 & 3.

SMD chips and resistors, but a very easy build with minimal components.

Build guide is HERE

Custom Neurotic panel

Oh yes I still make 4U
tho the astute may notice 2 eurorack modules have slipped into the gaps.

I forgot what a challenge the Neurotic panel is, the transient envelope generators approach weird from opposite directions.
