This is part 2 of my build notes for the Suppository of all Wisdom module.
It's supposed to be a phase shifter.
Part one of the build is here:
It's a vactrol controller phaser by NLC ( Nonlinear circuits).
The module combines ideas from the Steiner Phaser with the Lovetone Doppelganger.
It uses lots of LEDs and LDRs (Light dependent resistors).
The PCB so far.
I like to solder the ICs first.
The two phaser sections are in series and Andrew decided to drop
the stepped capacitors and use a 10nF thru-out instead.
I understand, there are 8 stages to this phaser.
There are 2 outputs named:
1. Stage 8
2. Mix out (this is a combination of stage 4 & stage 8)
There are 2 (audio) inputs:
AC in
DC in
There are 2 CV inputs/pots
Phase 1 and CV1 control stages 1-2,
Phase 2 and CV2 control stages 3-4.
I think the Colour Pots 1 & 2 are feedback pots.
One sends the signal from stage 4 back to stage 1 or into stage 5 (which totally
overloads stage 5 as it is already getting the same signal from stage 4….oh dear).
The other feedback pot sends the signal from stage 8 back to stage 1 or stage 4.
You'll be building a single light-tight box. with headers.... essentially make a big vactrol.
Made up of 4 LDRs surrounded by lots of LEDs.... everything effects everything else ...so results
might be a tad unpredictable.
Resistors & caps.
I'm using stepped caps
C1 = 4n7, C2 = 10n, C3 = 22n and C4 = 47n.
Schottky diodes
Headers to build the box
Andrew recommends :
"GL5506 or GL5516 or whatever"
I'm using GL5549 s only because I have a packet of them which I've hardly used .
LEDs:
Andrew recommends:
"red/yellow/green very bright ones"
+ LEDs
I'm going multi coloured.
Pretty !!!
Pots
