PCB Eurorack panels

These PCB panels are only used as panels, they do not have any components soldered to them.

PCB Eurorack panels

These arrived this morning. 2mm white PCB Panels. On a few of them the NLC logos are missing a few spots of ink (most are perfect) but on the whole they look fantastic.

cellF panel & PCB pics

CellF Action - PCB = USD65, Panel = USD100, assembled = USD990. Shipping for PCB & panel set or assembled is USD20 to anywhere.

These are to help builders see how the PCBs look and are connected to the panel.

action panel

divider with staircase, quad logic with resistor ladder & VC slew, Quad oscillator / low pass filter, VCO, chopper, VCA

Delay no more, Vactrol PiLL, DP filter

FF chaos, Sloth, offset mixer

The PCB is mainly held to the panel by the 81 (or so) jacks, but the two pots at this end of the panel are threaded and bolted to the panel.

VCO pics

These are pics of the VCO in the VCO panel. the PCB is available as a DIY project, so these pics are to help any builders.

cellF panel #2 - action

This is the 2nd panel for the cellF neuron controlled synth. It contains:

7 stage divider (from /2 to /128) with a staircase output
chained logic module with related but individual logic circuits, the outputs are connected via a resistor ladder to give a SOU266 style random stepped CV...which has voltage controlled slew so can be a random smooth CV if you prefer
QUO/LPF an effective low pass filter, quadrature oscillator with high/low range so can be used as a VCO or LFO
VCO: tri-core with tri & square outputs
Chopper....chop slewy!
VCA
Delay No More: updated version with vactrol based CV 'control' of both delay stages and individual signal inputs and outputs for each stage. It maintains the same functionality as the original PCB version but can also be tamed and actually used as a delay (just)
Vactrol PiLL: a PLL based audio/noise source, it has no knobs
DP Filter: same as the PCB version
Sloth: 15 minutes per cycle chaos module
FF Chaos: a gate/CV controlled chaos module that produces two chaotic CVs and 2 gates of chaotically varying widths.
Offset Mix: CV and audio mixer, pots 3 & 4 can be used to add negative or positive offset voltages if the inputs are unused.

Chopper

Chopper - expected this week. This is an analogue switch on steroids. The concept came from a 60s chopper modulator circuit. It can be used as a VCO, a VCF, a waveshaper, ring modulator, analogue switch, LFO and VC gate generator....probably more. It can switch between two input signals with the actual input signals deciding when to switch, or the change can be VC or manually controlled. There is also a bi-directional switch as a separate circuit on the same PCB. this is functionally the same as the early Serge bi-di Router but uses a DG411 analogue switch rather than a 4007 to do the work.
