A visit to Non Linear Circuits - Perth, Western Australia

While on a recent trip to Perth I dropped by to visit my friend Andrew F of  Nonlinear Circuits.

I got to meet Pinky :-)

This is "Synth Porn"

And even more famous than Pinky are Randy & Bill
Randy is on the left. Bill who is only 4 months old is on the right.

Back to the synths:
This is all Eurorack format, consisting of :
2 tri-core VCOs 
2 LFOs 
2 LPGs 
3 VCAs 
VC spring reverb 
jerkoff chaos 
2x  Buchla inspired 281 EGs 
Sauce of Unce (SOU). Based on the Buchla 265

A new NLC Serge format Panel.

This comprises:
Two VCOs
Vibes (a collection of fixed filters) 

This is part of an electronic analog computer which Andrew rescued many years ago.  It's programmed using patchcords that connect op-amps, capacitors, resistors, etc. to carry out calculations.

                                A adder circuit. It's a lovely illustration of how the Op amp's
                                    negative feedback can be used to do computations.

 This circuit adds the 3 inputs.
Vout = -R4[V1/R1+V2/R2+V3/R3]

                                                                     The integrator.
This op-amp circuit performs the mathematical operation of Integration

 The output voltage is proportional to the integral of the input voltage. (ie: the size of the output is controlled by the length of time a voltage is present at its input). This is determined by the negative feedback capacitor which charges/discharges.

I'm not sure of the age of this computer. Maybe 1950s /  1960's ????
It's beautiful though.

Death is indiscriminate. We will all have to face it one day.
