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
diff-rectifier
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
diff-rectifier
Vibes (a collection of fixed filters)
VCA
Mixer
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.
Pieter Brugel-the-elder, "The Triumph of Death"
c. 1562. The original can be found in the Museo del Prado, Madrid
Skeletons hauling a wagon full of skulls.
Death is indiscriminate. We will all have to face it one day.
