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
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
to be continued....
