Divine CMOS returns

This is a slimmed down and modified version of the 4U Divine CMOS.
It can be used as a CV pattern generator with slew, frequency divider, gate pattern generator, envelope follower and a ring modulator that provides sub-harmonics that can be mixed together to create new sounds.
PCB - USD18
Panel - USD20







Small PSU PCB

...what a lame name, I was gonna call it 'hard candy' but can't be bothered. It was designed to power stand-alone Null-A panels.
Anyway, its about a simple PSU as you can get. Runs on 7812 and 7912 to give +/-12V. If you bolt them to a nice big heatsink, you could even get 1A per rail (using 1.5A spec'd regulators).

This PSU is powered by a 12VAC wallwart, so no need to wire any mains voltages.

The design is a slimmed down version of a PSU we use in the WAMod workshops, the only differences are:
  • only 1 eurorack connector instead of 7 
  • no 5V section
  • holes for installing spade connectors
so keeping these differences in mind please refer to the WAMod PSU build guide when putting this together.

USD8 each

Plague of Demons - thru0 VCO

PCB set - USD26
panel - USD24
assembled = USD280

available now

Build guide and panel template

This VCO uses DG202 (or equivalents) analogue switches to achieve the thru 0 function, based on ideas presented in Electronotes EN#75.
Very nice demo of sounds by Steve:









note 20 Jan 2018 - just got asked about this, so to be clear: the thru-0 mark in the centre of the panel is simply to indicate what type of VCO this is. I have no connection with Antumbra modules which use the same mark on all their panels (and were released a few months after this one).
