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!
