Some pics of my build for the 2nd of 4 new plugins for the 3-trins video synthesizer by

This is slightly different to the previous 2SPDT/4SPST build.

This SPST & SPDT uses a CMOS 4066. It's a Quadruple Bilateral Analog Switch.

The SPST&SPDT behaves like a CV controlled switch.

There are just 2 switches:
Switch A on the front & switch B on the rear.

Switch A has the following connections (on the extreme right in the photo above):
<> 1CTRL: Toggle input
<> 1Anc: Normally connected
<> 1Bno: Normally open
<> 1AB:Pole/common connector

The  "1CTRL" input is where you plug your modulation source (such as a LFO).
The pot on the right appears to modulate the 1CTRL input

Switch B on the rear has these connections:
<> 2CTRL: Toggle input
<> 2Bno: Normally open (multiple connection)
<> 2Bno: Normally open
<> 2Ano: Normally open

The  "2CTRL" input is where you plug your modulation source (such as a LFO).
The pot on the left appears to modulate the 2CTRL input

tOP header

Testing the perspex guards.... the transistor needs to be bent down for everything to fit.

Example patch:

So you take a signal, eg video from the header and patch it to 1AB.
Then run G- to 1Anc and B- to 1Bno.
Now patch one of the LFOs (eg F01a) to 1CTRL. The knob on the right appears to set the point where switching occurs ...you should start seeing the video input jumping from B- to R- in time with the LFO.

The B side is similar, but it just connects two points On or off, instead of the A sides 'this or that'.
