NLC Tracky Dacks - build notes


 For those of you who aren't Australian, Tracky Dacks are Aussie Slang for tracksuit underpants/trousers.
To dak someone is to pull their pants down.

The module is a nice easy build. Easygoing, just like these clothes.
It's a voltage controlled envelope generator.

Its a bit like the Triad module, but the attack & decay use vactrols.

it is a simple circuit and the results are fun; lots of wobbly, evolving envelopes and it makes an interesting burst generator. 

It has an End-of-Cycle trigger output which restarts the
envelope if no gate is applied to the ‘Do It’ input

The official NLC Build guide is here

The wiki page is here:


"there are quite a few options to
choose when building this circuit or you can build it as per the PCB if
you prefer. The short version is build it as per the PCB except install
two 10M instead of the 2M2* " (NLC Build notes)..

Andrew recommends just installing 10M Ohms for both up & down vactrols


Some pics of the virgin PCB/panel


ICs first. 
a 555 timer and two 072 op amps


resistors next.
I'm installing 10M resistors for the vactrols instead of 2.2m





Caps next


BC847 transistor

and some signal diodes ...LL4148

NLC Motherload for 2022

 Andrew  of Nonlinear Circuits has been really busy this last year and I'm just catching up with a backlog of modules.


These are in the latest bunch of eurorack :



Frolic*
Intimacy*
The Sup of all wisdom*
Ming Rod
FM OP - six 
4HP Mix - 3 
Valmorification*
Encephalo Adjuster*
Poultry in Motion*
Flipflop chaos*
Tracky Dacks*
VC ADSR*
Sauce of Uncle*



I love building NLC modules. Andrew's build notes are educational in addition to making the builds easy.

NINA - 12 Voice Polysynth with Motorized Recall & Automation

...

Can't wait to see this. 
They will be launching on  kickstarter in about a month or so.
Finally, motorized rotary encoders which show your updated settings when you recall different patches.
It's interesting that drone technology is behind this development. 

 Its a twelve voice analog desktop polysynth with motorized knobs, from Australia.

Rome Panaromas

 Some pics of the Eternal City.

..



These  were taken with a old film-analog (panaromic) camera.
The Camera was a Russian Zenit Horizon 35mm.
I attempted to scan the negatives -- a bit washed out. One day I'll get these printed properly.
