Vactrol Folks (Part Two)

The vactrol project mutated into a triple passive VCA/Low Pass Gate with selectable filters on each LPG. On top of that I seem to have developed a taste for point to point wiring...

Hello Friend

I built this module back in (I think) 2003, it's the CatGirlSynth CGS30 Band Pass Filter. Based on the Roland SH5 it's a simple little circuit so I built two. Unfortunately it fell victim to a ruthless pruning of the modular when I moved house so I sold it via VEMIA in 2008. It's one of those modules I kind of regret selling, so I was on the verge of buying a couple of boards and building another one when it popped up again at VEMIA more recently. I missed buying it back that time, but it has popped up again on eBay here

I love these sightings of my modules in the wild

Fly little one, fly !

Vactrol Folks..!

I'd been making vactrols, but it turns out managed to kill most of the LEDs with my heat gun. After hours of messing around with heatshrink, LEDs, LDRs, superglue and plastic foam wadding I gave up and just ordered some Xvive vactrols from Thonk...

Dalek Table II

I decided to rebuild the passive ring modulator properly with matched transistors and the correct kind of transformer. Not surprisingly these changes made all the difference with a more defined 'ring mod' sound and much much better carrier suppression. In this version I used Triad TY141P transformers (10K:10K) and BAT48 diodes

VC Oh..!

I was just waiting on my Half Wave Rectifier panel drying and thought I'd try out a CD40106 VCO design using (since it's simple enough) the old croc clips and gravity prototyping method. I'm going to have to build yet another case now.

And so it begins again...

24-24

Here's another thing I've had hanging around unfinished for far too many years, the Highly Liquid MD24 - a MIDI to gate converter. I finally wired this up last week and used a 3mm plywood offcut for the panel. The case has also been hanging around for a while, it's an ex BBC desktop case probably used to house a reverb remote - more recently it housed my Bat Detector...

Want Some Candy ?


I checked my trailcam for the first time in ages and found the cat had managed to trigger it just as the light was fading enough for infra-red mode
