These are some build notes for the Poultry in Motion module.
Its a nonlinear circuits eurorack module.
Its got lots of uses.
VC Delay with a sync out.
Clock-divider
Clock (the PT2399 is the clock source)
VCO (with 12 suboscillator outputs)
Some pics of the virgin PCBs
The module uses a PT2399 chip.
It's a pretty common echo/delay chip used
in lots of guitar pedals.
Its CMOS technology developed by Princeton Technology Corp.
The PT2399 integrates a small DSP (with memory),
AD and DA converters.
a clock that manages the delay time and several op-amps.
This is all in the one chip

+ wiki
+ BOM
Parts:
The ICs from Mouser:
771-HEF4060BTD-T
595-SN74HC4040NS
The module also uses a vactrol.
DIY is fine with GL5506/GL5516, LED
and some heatshrink,
otherwise
something like NSL-32 will do
toggle switch
tayda a-4567
spdt on-on
LL4148 x 5
Radio diodes
Schotty diode - mouser
LM7805 voltage reg
Using a IC version
The bevel is on pin 1 side
BC847 & BC857 transistors
To be continued......
waiting on some parts.
